Insertion ABS Box Module
Plug-In PLC Power Distribution Modules
Fiber Optic Insertion ABS Box and LGX PLC Splitter Modules
These passive fiber-optic modules divide optical power in FTTH and PON networks; they are not automotive ABS control modules. Shortlist by split ratio, then approve the connectorized module against the PON loss budget and the physical interface of its distribution box, cabinet or LGX-style shelf.

Quick Answer
What Is an Insertion ABS Box Module?
An insertion ABS box module is a passive fiber-optic PLC splitter in a removable, front-access housing. Supplier catalogs may call it an insertion module PLC splitter, plug-in splitter or LGX PLC splitter module, but those labels do not establish universal dimensions. Approval requires two separate checks: optical performance against the PON budget and mechanical compatibility with the host slot, ports and maintenance clearance.

Package Comparison
Insertion Module vs Cassette and Rack-Mounted PLC Splitters
Choose the package by the installed interface and maintenance method. Similar splitter ratios do not make these packages mechanically interchangeable.
| Decision Point | Insertion ABS Box / LGX Module | Cassette PLC Splitter | Rack-Mounted PLC Splitter |
|---|---|---|---|
| Installed Interface | Removable module with front-access adapters in a compatible slot or shelf | Protected ABS cassette with external pigtails routed inside a host enclosure | Complete rack unit for a defined cabinet width and rack space |
| Primary Fit Check | Module width, height, depth, guides, fixing and insertion clearance | Cassette footprint, pigtail exit, bend control and tie-down space | Rack width, rack units, mounting depth, rear clearance and cable management |
| Maintenance Access | Front connector access and a clear module removal path | Enclosure access without stressing external pigtails | Front and rear access according to the rack design |
| Use This Page When | The host accepts a plug-in insertion or LGX-style module | The project needs a protected cassette with routed pigtails | The splitter is specified as a rack-mounted assembly |
Decision Boundary
When to Choose — or Reject — an Insertion / LGX Module
A plug-in format earns its place only when it improves access without creating a fit or loss problem. Use the installed assembly, not the package name, as the decision unit.
| Project Condition | Decision | Reason and Required Evidence |
|---|---|---|
| Compatible LGX-style slot with front adapter access | Shortlist insertion / LGX | Obtain the host and module drawings; confirm guide, fixing, insertion direction, populated depth and removal path. |
| Compact FDB with protected internal routing but no plug-in slot | Compare blockless or ABS cassette | A smaller package may fit the tray and bend-control layout better; verify pigtail exits and strain relief. |
| Many splitter ports managed as one rack assembly | Compare a rack-mounted splitter | Rack-level cable management and access may be clearer than multiple unmatched modules. |
| Outdoor location without a rated host enclosure | Reject the module-only proposal | The module does not replace the site enclosure. Specify sealing, cable entry, condensation control and environmental qualification separately. |
| Supplier cannot provide a dimensional drawing or terminated optical limits | Hold purchase approval | A matching ratio and connector label cannot establish mechanical fit or end-to-end loss compliance. |
Selection Guide
How to Choose an Insertion ABS Box Module
A matching output count is only the first filter. Use the fields below to build a requirement that engineering, purchasing and the supplier can verify against the same documents.
| 1×N or 2×N Configuration | State the exact input and output count. For a 2×N design, explain how both inputs are used and define the required input and output identification. |
|---|---|
| Host Slot and Module Dimensions | Match width, height and depth to the approved slot or reserved mounting area. Verify the guide, fixing method, insertion clearance and removal path. |
| Mounting and Insertion Direction | Confirm front or rear insertion, adapter orientation, door clearance and access for installing or removing the module without disturbing adjacent fibers. |
| Adapter Count and Port Map | Define every input and output adapter, port-label sequence and cascade stage. Confirm that the host panel provides the correct opening and connector access. |
| Connector and Polish | State the interface and UPC or APC polish for every port. Confirm mating adapters and patch cords; APC and UPC interfaces must not be physically mixed. |
| Optical Budget | Calculate acceptable loss for every route, including the splitter, connectors, splices, fiber distance, equipment margin and any cascaded splitter stage. |
| Insertion Loss and Uniformity | Use the maximum insertion-loss and channel-uniformity values for the exact configuration. Do not substitute a generic category claim or another split ratio. |
| Wavelength, PDL, Return Loss and Directivity | Define the operating band and acceptance limits for the complete connectorized module. Check the exact model datasheet and test record. |
| Test Data and Documents | Request the current model datasheet, optical acceptance limits, port map, dimensional drawing and any project-specified compliance evidence. |
| Model | Published Configuration | Selected Published Limits | Buyer Action |
|---|---|---|---|
| BWN-PLC-IM-1X2-SC-APC | 1×2, SC/APC, G657A or customized fiber | 1260–1650 nm; insertion loss 3.8/4.0 dB for P/S grades; return loss 55 dB; −40 to 85°C | Confirm the grade, dimensions and port layout on the current datasheet. |
| BWN-PLC-IM-1X8-SC-APC | 1×8, SC/APC, G657A or customized fiber | 1260–1650 nm; return loss 55 dB; −40 to 85°C | Request the model-specific insertion-loss, uniformity and dimensional limits. |
| BWN-PLC-IM-2X4-SC-APC | 2×4 LGX/insertion module, SC/APC, G657A or customized single-mode fiber | 1260–1650 nm; insertion loss ≤7.6 dB; uniformity ≤1.0 dB; PDL ≤0.3 dB; return loss 55 dB; −40 to 85°C | Define the use and labeling of both inputs, then verify host-shelf fit. |
Specification notice: Published figures above are model-specific sourcing references, not category-wide guarantees. “G657A” does not establish whether a model uses G.657.A1 or G.657.A2; confirm the exact fibre designation when it matters to the project. Availability, dimensions, optical limits, connector configuration, environmental range and compliance evidence remain subject to the approved datasheet, drawing, test criteria and order documents.
Procurement Controls
Mistakes to Avoid Before Sample or Batch Approval
Treat each item below as a release gate. If the evidence is missing, record an open point rather than converting an assumption into a purchase specification.
| Common Mistake | Field Consequence | Corrective Check |
|---|---|---|
| Buying by “LGX” name alone | The module may not engage the guides, fixing point or available depth. | Approve dimensioned module and host drawings with the same revision reference. |
| Using bare-device loss as the installed limit | Adapters and mated connectors consume unrecorded budget. | State whether limits include connectors and test the complete terminated path. |
| Leaving APC / UPC polish implicit | Wrong mating interfaces can create reflection and physical damage risk. | Put polish, connector family and adapter orientation on the BOM and port map. |
| Approving an empty-box fit | The door may load connectors or force patch cords below their routing radius. | Check the populated assembly with boots, patch cords and the door in its operating position. |
| Accepting one sample without batch traceability | Later deliveries may change labels, housing, interfaces or optical grade unnoticed. | Freeze the approved revision and link batch test records to model, PO and lot. |
What Changes Cost and Lead Time?
A public unit price is not a project quotation. These variables change material, assembly, testing, documentation or schedule; ask suppliers to identify them separately.
| Driver | Why It Changes the Offer | RFQ Instruction |
|---|---|---|
| Split ratio and 1×N / 2×N topology | Port count changes the PLC device, adapter count, housing width and test paths. | State every input and output and identify any cascade stage. |
| SC or LC, APC or UPC, and adapter loading | Interface choice changes components, polishing, assembly and complete-path loss. | Define both ends and require confirmation that quoted loss includes the ordered interfaces. |
| Custom housing, guides, labels or port map | Mechanical changes require drawing control, tooling or nonstandard assembly work. | Separate standard and customized items; request drawing approval before production. |
| Test and compliance evidence | Port-by-port records, environmental evidence or customer-specific reports add work beyond a generic certificate. | List required methods, limits, sample size, report fields and document language. |
| Quantity, packaging and delivery schedule | Component allocation, lot size, serialization and export packing affect production planning. | State sample and batch quantities, destination, required date and repeat-order forecast without assuming a guaranteed lead time. |
Practical Deployment Review
Three Fit Problems a Datasheet Alone May Not Reveal
A module can match the listed slot dimensions and still be difficult to install or maintain. Review the assembly with adapters populated and the enclosure in its normal operating position.
Door and Connector Clearance
Housing depth is not the complete installed depth. Add the adapter, connector body, strain relief and the patch-cord route; then check that the door closes without forcing a bend or loading the adapter.
Removal Without Service Disruption
Confirm that technicians can release and remove the module without unplugging unrelated subscriber ports or pulling adjacent fibres. A removable module has little maintenance value when the release point is blocked.
Outdoor Enclosure Boundary
The host box provides sealing, cable-entry control and site protection. A published module temperature range does not, by itself, establish that the connectorized assembly is suitable for rain, dust, condensation or the local enclosure environment.
Illustrative FTTH scenario (not a customer case): for a wall-mounted distribution box using a 1×8 SC/APC module, approve the slot with all nine front interfaces represented, the intended patch-cord route in place and the door closed. This exposes connector-clearance and bend-control conflicts that an empty-box dimensional check can miss.
Standards and Evidence
How Standards Support Model Approval Without Replacing It
Use standards to define the system context or test method, then require evidence for the exact ordered assembly. A reference to a standard is not proof that every model in a category has been tested or certified to it.
| Reference | Relevant Scope | Correct Use on This Page | What It Does Not Prove |
|---|---|---|---|
| ITU-T G.984.2 | GPON physical media dependent layer and optical-network requirements | Use as system context when the project defines the PON path budget and physical-layer limits. | It does not certify a BWNFiber splitter model or establish host compatibility. |
| IEC 61300-3-4:2023 | Methods for measuring attenuation of optical components | Reference the project-approved method when specifying insertion-loss measurement. | A method reference does not establish the acceptance limit or show that a model passed. |
| IEC 61300-3-6:2008 | Return-loss measurement procedures for a fibre-optic device under test | Use when the order or test plan calls for return-loss measurement. | It does not replace a model-specific test record. |
| IEC 61300-3-35:2022 | Visual inspection of connector end faces | Use to define inspection of debris, scratches and defects before mating. | Visual inspection does not replace attenuation or return-loss measurement. |
| IEC 61753-031-2:2014 | Performance requirements for non-connectorized single-mode 1×N and 2×N branching devices in a controlled environment | Use only when the project and supplier evidence match the standard's exact device and environment scope. | Its scope does not automatically qualify a connectorized insertion-module assembly. |
What BWNFiber Can Review From the Inquiry
BWNFiber can compare the submitted topology, host drawing, interface schedule and acceptance requirements with published configurations, then identify fields that still need model-document confirmation.
What the Project Owner Must Approve
The network designer or project owner remains responsible for the PON budget, host enclosure, applicable standard editions, environmental conditions and final acceptance criteria. These inputs cannot be inferred from a category name.
Supplier Selection
Compare Suppliers by Evidence, Not Adjectives
“High reliability” and “standard LGX” are not acceptance evidence. Score each bidder against the same project documents and keep unsupported fields open.
| Evidence Category | Minimum Review Item | Escalate When |
|---|---|---|
| Mechanical compatibility | Revision-controlled dimensioned drawing, guide/fixing details, adapter orientation and installed clearance | The drawing is generic, undimensioned or does not identify the quoted model. |
| Optical acceptance | Exact split ratio, grade, connector condition, maximum insertion loss, uniformity, PDL, return loss and test method where specified | Values mix bare devices and connectorized assemblies or omit maximum limits. |
| Port and label control | Approved port map, input/output identification, label content and orientation | A 2×N input function or field port sequence is left to production interpretation. |
| Traceability | Model, drawing revision, PO/lot reference and test record linked to the delivered batch | The report cannot be matched to the received units or approved revision. |
| Change control and repeat supply | Written notification requirement for housing, fiber, connector, label or performance-grade changes | The supplier may substitute components without buyer approval. |
| Project support boundary | Clear statement of what the supplier can verify and what remains the network designer's responsibility | The bidder guarantees network performance without the topology, link budget or site conditions. |
BWNFiber capability boundary: BWNFiber can review a submitted topology, host drawing, connector schedule and acceptance requirement against an available module configuration. Final compatibility, standards applicability and network acceptance remain subject to the approved documents, the delivered lot and the project owner's validation.
Buyer Checklist: Resolve Four Approvals Before the PO
Do not let a single model name stand in for the full requirement. Record one approved value or drawing for each decision below so purchasing does not have to interpret an engineering assumption.
- Topology approval: 1×N or 2×N configuration, cascade position and port map
- Mechanical approval: host drawing, module envelope, guides, fixing and removal path
- Optical approval: per-path budget, connector interfaces and model acceptance limits
- Commercial approval: exact revision, quantity, label/packing rules, required evidence, destination and schedule
If any one of these approvals is missing, keep the model at shortlist status rather than treating it as purchase-ready.
Inspect the First Approved Assembly
Use the approved drawing, port map and optical limits as the acceptance baseline. A generic category sheet cannot show whether the delivered module matches the intended slot and terminated optical paths.
- Compare dimensions, guides and fixing points with the approved host drawing.
- Check input/output count, adapter orientation, port labels and connector polish.
- Review housing condition, adapter alignment and connector end faces.
- Verify insertion loss and channel uniformity for every required path.
- Check PDL, return loss, directivity, wavelength and temperature only where the order documents specify them.
- If OTDR is used for installed-link troubleshooting, do not treat it as a substitute for the specified component attenuation and return-loss measurements.
- Retain the test record against the model and order reference.
FAQ
Insertion ABS Box Module Selection Questions
Short answers to the questions that usually block model approval or a complete quotation.
What is an insertion ABS box module?
An insertion ABS box module is a PLC splitter housed in a compact plug-in enclosure with accessible input and output adapter ports. It is designed for an approved slot, shelf or reserved space inside a distribution box, cabinet or panel.
Is an insertion ABS box module the same as an LGX PLC splitter?
BWNFiber's insertion category includes models described as LGX cassette or insertion modules. However, LGX dimensions and mounting details must be confirmed for the exact host shelf or box; the category name alone does not guarantee fit.
What is the difference between an insertion module and a cassette PLC splitter?
An insertion module presents adapters on a plug-in housing for direct connector access. A cassette PLC splitter in BWNFiber's separate CT category uses an ABS protective housing with external pigtails. Choose by host mounting, interface and maintenance method.
Why use a plug-in PLC splitter module?
A plug-in module can concentrate splitter protection, adapters and port labels in a removable unit, which may simplify access and replacement. The benefit depends on an exact mechanical match with the host enclosure and enough connector clearance.
Which 1×N and 2×N insertion module configurations are available?
BWNFiber publishes insertion examples across 1×N and 2×N configurations, including 1×2, 1×8 and 2×4 models. Exact availability, module size, port arrangement and optical limits must be confirmed for the requested model.
How do I choose the host box or LGX shelf?
Confirm the slot width, depth and height, fixing or guide system, insertion direction, front clearance, adapter count, cable routing, door clearance and environmental protection. Approve the module and host enclosure as one installed assembly.
How do I choose the adapter interface and connector polish?
Match the adapters to the network interface. APC and UPC interfaces must not be physically mixed. State the connector family, polish, input and output count, adapter orientation and port numbering in the order specification.
What is the difference between 1×N and 2×N insertion modules?
A 1×N insertion module uses one optical input, while a 2×N module uses two. For a 2×N requirement, define how both inputs are used, label every port and calculate the optical budget for each input-to-output path.
Which optical specifications should be checked for an insertion module?
Verify insertion loss for every path, channel uniformity, polarization-dependent loss, return loss, directivity, operating wavelength and temperature for the exact model. Connectorized assemblies require acceptance limits for the complete terminated configuration.
Can an insertion module be installed outdoors?
An insertion module may be installed only inside an outdoor enclosure approved for the location. The plug-in splitter itself should not be treated as a standalone weatherproof enclosure; verify the host box rating, sealing, cable routing and model temperature limits.
What technical documents should be checked before approval?
Request the model datasheet, dimensional drawing, port map, optical test limits and any project-required compliance evidence. A category-page statement does not establish the same dimensions, performance or qualification for every model.
What information is needed for an insertion module quotation?
Send the 1×N or 2×N configuration, module or slot dimensions, host enclosure, adapter count, connector and polish, fiber requirement, optical limits, labels, quantity and schedule. Include a PON budget, BOM or reference model when available.
Applications
Insertion ABS Box Module Applications
The same splitter package behaves differently depending on where technicians must insert, connect and later remove it. Review the application by access and protection requirements.
Wall-Mounted Distribution Boxes
Use a plug-in module only when the box provides a defined mounting space, reachable front adapters and a fiber route that remains clear when the door closes.
LGX Shelves and Optical Cabinets
Prioritize repeatable insertion, visible port identification and removal without disturbing adjacent modules or patch cords.
Indoor and Outdoor PON Nodes
The host enclosure, rather than the plug-in module, must provide the environmental protection required at the site. Verify sealing and cable entry separately from splitter performance.
Move From Shortlist to Approved Configuration
Need Insertion ABS Box Modules for a PON Project?
Send the BOM, host drawing and optical budget you have. The response can then focus on unresolved fit, interface and acceptance details instead of repeating information already defined by your project.
