Fiber Distribution Box
Fiber Optic Distribution Boxes for FTTH and FTTx Networks
Choose a fiber optic distribution box by the network node it must serve, not by port count alone. Match the splitter and splice plan, feeder and drop cables, connector interfaces, mounting method, environment and complete scope of supply, then send your BOM or network drawing for a model-level review.

Product Selection
Quick Selection Answer
First identify the network node and whether the project needs a conventional splitter-ready enclosure, a loaded PLC splitter box or a pre-connectorized fiber distribution box. Then verify adapter positions, splitter outputs, splice capacity, cable outside diameters, connector interfaces, mounting, environment and complete scope of supply. Approve the current drawing and BOM before relying on a model name or port count.

Fiber Distribution Boxes by Enclosure Material
These material groups are commercial starting points. Exact capacity, cable-entry range, dimensions, protection claims and supplied accessories belong on the individual product page and approved drawing.
Plastic Fiber Distribution Box
Plastic enclosures are a starting point for compact indoor, protected outdoor, wall-mounted and selected pole-mounted FTTx nodes. Confirm the exact resin, UV requirement, sealing, impact requirement and declared installation environment.
View plastic distribution boxesMetal Fiber Distribution Box
Metal enclosures suit projects that prioritize a rigid housing, secure access, structured wall mounting or higher-capacity organization. Confirm corrosion protection, coating, lock design, mounting hardware and the intended environment.

How to Select a Fiber Distribution Box
Shortlist by node function first, then reconcile port capacity, splitter outputs, splice capacity, cable entries, optical interfaces, material, mounting and maintenance access against the current drawing and BOM.
Six Checks Before Model Approval
- Define the network node — feeder split point, building entry, floor or MDU distribution point, pole-mounted subscriber node, pre-connectorized access point or final drop point.
- Separate the capacity figures — record adapter positions, splitter outputs, working splices, pass-through fibers and reserve separately.
- Build the cable-entry schedule — list feeder, branch and drop cables by quantity, outside diameter, direction and any mid-span requirement.
- Define the optical interface — specify connector family, APC or UPC polish, PLC ratio and package, pigtails and loaded, unloaded or pre-connectorized scope.
- Match material and environmental evidence — state climate, sun, dust, rain, flooding, corrosion, impact and mounting requirements; do not rely on an IP code alone.
- Check access and maintenance — review cover access, tray movement, fiber storage, bend control, labels, unused-port sealing and technician working clearance.
Nine RFQ Fields That Prevent Configuration Mismatch
| Network Position | Send the node type and a simple route diagram to establish the required functions. |
|---|---|
| Subscriber or Branch Outputs | List working outputs plus documented reserve to define adapter and splitter requirements. |
| Splitter Plan | Specify ratio, quantity, package and input/output connectorization to determine mounting and routing space. |
| Splice Plan | List feeder, branch, pigtail, pass-through and reserve splices to determine tray and storage needs. |
| Cable Schedule | Provide cable type, quantity, outside diameter, entry direction and any mid-span requirement. |
| Connector Interface | State connector family, APC or UPC polish, adapter quantity and pigtail plan. |
| Scope of Supply | Define unloaded, loaded or pre-connectorized scope so the quotation includes the intended components. |
| Installation Environment | State indoor or outdoor use, wall, pole or aerial mounting, climate and exposure. |
| Approval Package | Identify required drawings, BOM, sample, labels, test records and packaging before production. |
Compare Fiber Distribution Box Types
Use these product groups as commercial starting points. Keep exact dimensions, capacities, environmental claims and included accessories on the individual product page and approved drawing.
| Product Group | Starting Point | Buyer Must Verify |
|---|---|---|
| Plastic Distribution Box | Compact indoor, MDU, wall or selected outdoor FTTx points | Resin, UV exposure, sealing, impact, mounting and cable entries |
| Metal Distribution Box | Telecom rooms, secure wall mounting and organized higher-capacity distribution | Coating, corrosion environment, lock, grounding or bonding and hardware |
| SMC Distribution Box | Outdoor routes with project-specific mechanical and environmental requirements | Model-specific ingress, UV, impact, sealing and installation orientation |
| Splitter-Ready Box | Projects that install the PLC splitter separately | Splitter package, available space, pigtail routing, splice and adapter plan |
| Splitter-Loaded Box | Projects that require a defined factory assembly | Complete BOM, connector polish, optical test scope, labels and spare outputs |
| Pre-Connectorized Box or FAT | Quick ODN and reduced field-termination workflows | Interface family, port map, matching drops, unused-port sealing and compatibility |
Have a BOM, Network Drawing or Reference Model?
Send the node position, required outputs, splitter and splice plan, cable outside diameters, connector interface, mounting, environment, quantity and approval-document requirements. BWNFiber can identify candidate models and unresolved specifications before quotation.
Send your project package for a configuration reviewBuyer Approval Workflow
Approve the complete supplied configuration, not only the enclosure name. Configuration options are model-dependent and must be confirmed for the selected model and order.
- Send the network node, splitter plan, cable schedule, connector interface, environment and target quantity.
- Shortlist by function first, then material, mounting and nominal capacity.
- Request the current model drawing and a line-item BOM for the supplied assembly.
- Reconcile adapter positions, splitter outputs, splice capacity, cable entries, dimensions and accessories.
- Define sample or first-article approval when configuration risk justifies it.
- Approve labels, packing list, test-document scope and production configuration before release.
Quality Control and Test Evidence to Request
Quality approval should cover the supplied assembly rather than the empty enclosure alone. Define the evidence, pass criteria, sample size and report format in the RFQ.
- Current model drawing and line-item BOM for the enclosure, optical components and accessories
- Adapter panel, port map, connector orientation, PLC splitter and pigtail routing where included
- Splice trays, storage, cable entries, fixation parts, seals and unused-port plugs
- Continuity, insertion-loss, polarity or port-map records for loaded and pre-connectorized units when required
- Standard, tested configuration, cable seals, mounting orientation and validity conditions behind environmental claims
- Labels, mounting hardware, packing list and approved loaded or unloaded scope
Important: document availability depends on the model and ordered configuration. State each required record in the RFQ instead of assuming a category-wide test statement covers the order.
FAQ
Fiber Distribution Box Buying Questions
Eight buyer-focused answers for model matching, configuration approval and quotation preparation.
How many ports should a fiber distribution box have?
Use the approved subscriber or branch plan, documented reserve, splitter outputs, adapter positions and splice plan. Do not select capacity from subscriber count alone because the same nominal port count can represent different internal configurations.
What is the difference between an unloaded, loaded and pre-connectorized box?
An unloaded box omits some or all optical components. A loaded box includes a defined set of adapters, pigtails, splitters or trays. A pre-connectorized box is designed around a specified connectorized distribution system. The line-item BOM is the controlling document.
Can a fiber distribution box include a PLC splitter?
Selected models provide a defined splitter position or a loaded splitter configuration. Confirm the supported package, ratio, connectorization, pigtail routing and remaining splice and storage space for the exact model.
What quality documents are available?
Document availability depends on the model and ordered configuration. State the drawing, BOM, material declaration, optical test record, ingress evidence, inspection record and packing-list requirements in the RFQ.
Are all fiber distribution boxes IP65 or IP68?
No. Confirm the cited standard, tested configuration, cable seals, installed orientation and report. Assess UV, corrosion, impact, temperature, mounting and any regional enclosure requirement separately.
What information is needed for a fiber distribution box quotation?
Send the network node, port and splitter plan, splice plan, cable schedule, connector interface, mounting, environment, scope of supply, quantity, target schedule and required approval documents.
Can BWNFiber customize the adapter, splitter and cable-entry configuration?
Configuration options are model-dependent. Send the drawing or reference model and identify every requested change so engineering limits, tooling, MOQ, lead time and any sample process can be confirmed for the selected series.
What are the MOQ and lead time?
They depend on the model, loaded or unloaded scope, customization, quantity, material availability, sample approval and shipping plan. Confirm both values in the quotation for the approved configuration.
Applications
Fiber Distribution Box Application Scenarios
The network position changes the required splitter, adapter, cable-entry, sealing and mounting arrangement. Use these scenarios to narrow the shortlist before model-level approval.
Building and MDU Distribution
Match wall-mounted FTTH distribution boxes to the riser or floor cable plan, adapter count, splitter position, technician access and available installation space.
Outdoor Wall and Pole Distribution
Confirm mounting hardware, installed orientation, cable approach, sealing components, unused-port plugs, sun exposure, water path and the evidence required for the declared protection level.
Pre-Connectorized Quick ODN Nodes
Approve the box, splitter, port map, connector interface, matching drop cable, unused-port protection, labels and cleaning method as one system.
