Find Bare Fiber PLC Splitters for Splice Tray Integration
A bare fiber PLC splitter is the most compact PLC package: no steel tube, ABS cassette or rack chassis. It is designed to live inside a splice tray, closure or module that provides mechanical protection, bend control and fiber storage. Start with the published products above, then eliminate options that do not match the split configuration, package dimensions, fiber construction, pigtail length, termination, tray routing or optical budget.

Selection Guide
Compare Bare Fiber PLC Splitter Specifications Before Selecting a Model
Use these fields to shortlist bare fiber PLC splitter options before reviewing the exact datasheet and host-tray drawing. A matching output count does not confirm package fit, fiber protection or optical compatibility.
| 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. |
|---|---|
| Package Dimensions and Tray Fixation | Match the exact length, width and height to the available tray area. Confirm the fiber-exit direction, approved holder or fixation, strain control, bend management and cover clearance. |
| Fiber Construction | State whether the requirement uses 250 µm coated fiber or another approved buffer construction. Do not infer the lead construction from the words “bare fiber” alone. |
| Input and Output Length | Measure each route inside the tray or enclosure and include controlled service slack. Specify input and output lengths separately when the paths differ. |
| Termination and Splicing | Define unterminated leads, fusion splices or any connectorized ends. Confirm splice-protector storage, adapter capacity and label sequence in the host enclosure. |
| 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 terminated splitter. Check the exact configuration datasheet and test record. |
| Standards and Compliance | Verify applicable standards including ITU-T G.657, G.652.D and the relevant IEC/ITU optical fiber requirements for the selected fiber grade and splitter application. |
| Test Data and Documents | Request the current model datasheet, optical acceptance limits, port map, dimensional drawing and any project-specified compliance evidence. |
Published BWNFiber 1×4 Reference and Evidence Limits
Published 1×4 optical reference: BWNFiber’s current 1×4 specification page lists a 1×4 PLC option with maximum insertion loss ≤7.6 dB, uniformity ≤0.8 dB, APC return loss ≥55 dB, a 1260–1650 nm wavelength range and G.652.D or G.657.A2 fiber options. These values belong to that published 1×4 reference only and must not be applied to every bare fiber configuration.
Published bare-fiber form-factor reference: the same guide lists a 40×3×3 mm bare fiber form factor for a splicing tray or inline closure. Treat that dimension as a published 1×4 reference only; confirm the drawing for the requested splitter ratio and termination.
Package boundary: a BWNFiber blockless-mini page describes the steel-tube package as providing stronger shielding than a bare fiber splitter. The bare version therefore requires a host tray or enclosure designed to protect the splitter body, fiber transitions and stored leads.
Important: A complete current bare-fiber model inventory should be confirmed at quotation. No single dimension, insertion loss, uniformity, PDL, return loss, wavelength, temperature, fiber construction or termination statement applies across the entire category.
Package Comparison
Bare Fiber PLC Splitter vs Blockless Mini, Cassette and Rack Packages
Compare package families to decide whether the project should stay with a bare-fiber form factor or move to a blockless mini, cassette or rack-mounted PLC splitter package.
Bare Fiber PLC Splitter
Best for high-density splice trays, ODF modules and closures where minimum package volume is critical and the host tray can secure the assembly and manage 250 µm lead routing.
Blockless Mini PLC Splitter
Offers stronger secondary mechanical protection than bare fiber while keeping a compact steel-tube package. Suitable where fiber protection and handling robustness matter but tray space remains constrained.
Cassette PLC Splitter
Uses ABS cassette packaging with accessible pigtails and modular installation. Suitable for LGX and subscriber distribution boxes where connector access and module replacement are priorities.
Match Bare Fiber PLC Splitters to Your Tray, Closure and PON Budget
A reliable match starts with the PON topology, allowable path loss and protected tray design—not the compact package or advertised channel count alone. BWNFiber can compare the requirement with available bare-fiber references.
- 1×N or 2×N input and output configuration
- Split plan, cascade stage and port-label sequence
- Optical budget for every subscriber or branch path
- Splitter dimensions, fiber-exit direction and tray clearance
- Holder, fixation, strain control and bend management
- Fiber construction and input and output pigtail lengths
- Fusion-splice or connector termination and labels
Inspect the Complete Bare Fiber Splitter Assembly
Inspection requirements should follow the approved configuration, datasheet and order requirement. Review the optical paths and physical assembly together, including the compact splitter body, fiber exits, pigtails, labels, splices and tray fit.
- Input and output configuration and visible port mapping
- Insertion loss and channel uniformity for every path
- PDL, return loss, directivity and required wavelength limits
- Splitter dimensions, body condition and fiber-exit direction
- Fiber construction, pigtail lengths, labels and strain protection
- Splice or connector condition and optical test record
Important: Configuration, package dimensions, tray fit, insertion loss, uniformity, PDL, return loss, directivity, wavelength, temperature, fiber, termination and compliance evidence must be verified for the exact order; they should not be assumed across the category.
FAQ
Bare Fiber PLC Splitter Selection Questions
These questions cover tray fit, fiber protection, pigtail routing, optical-budget control and quotation preparation for bare fiber optical splitters.
What is a bare fiber PLC splitter?
A bare fiber PLC splitter is a compact planar-lightwave-circuit splitter supplied without the larger steel-tube, ABS cassette, LGX or rack housing used by other packages. It normally relies on an approved splicing tray or enclosure for routing, strain control and mechanical protection.
What is the difference between bare fiber and blockless mini PLC splitters?
A bare fiber splitter provides less secondary mechanical protection around the PLC assembly and fiber transitions. A blockless mini splitter uses a steel-tube package. Choose by available tray space, fiber protection, fixation and maintenance risk rather than size alone.
Is a bare fiber PLC splitter the same as an unpackaged PLC chip?
Not necessarily. Bare fiber describes a compact splitter form factor with fiber leads and limited secondary protection; it does not prove that the internal waveguide chip is completely unpackaged. Request the exact construction drawing instead of inferring the internal package from the category name.
Where should a bare fiber PLC splitter be installed?
Install it only in a compatible splicing tray, module or enclosure that provides fixation, bend control, fiber storage and environmental protection. Verify usable tray dimensions and cover clearance before approving the splitter package.
Which bare fiber PLC splitter configurations are available?
BWNFiber publishes a 1×4 reference that includes a bare fiber form factor. A complete current bare-fiber model inventory should be confirmed at quotation. Specify the requested 1×N or 2×N configuration, dimensions and optical limits before ordering.
How should 250 µm fiber and pigtail length be specified?
State the required input and output coating or buffer construction and measure each route inside the host tray. Specify input and output lengths separately when needed, with controlled service slack and no unsupported tight bends.
Are bare fiber PLC splitters supplied with connectors?
Do not assume the termination from the form-factor name. Define whether each lead is unterminated for fusion splicing or connectorized, and state any connector family and polish. The host tray must protect every splice, adapter and fiber transition.
How should a bare fiber splitter be protected in a tray?
Secure the splitter body in an approved holder, maintain the minimum bend control required by the selected fiber, protect transitions from pulling and crushing, and store service slack without crossing moving covers or tray hinges.
Which optical specifications should be checked for a bare fiber splitter?
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 a bare fiber PLC splitter be installed outdoors?
Only inside a closure, terminal or cabinet approved for the outdoor environment. The bare fiber splitter itself is not the environmental enclosure; verify host sealing, water protection, fiber routing, fixation and model temperature limits.
What technical documents should be checked before approving a bare fiber PLC splitter?
Request the model datasheet, dimensional drawing, port map, optical test limits and any project-required compliance evidence for the exact bare fiber PLC splitter. A category-page statement does not establish the same dimensions, performance or qualification for every model.
What information is needed for a bare fiber PLC splitter quotation?
Send the 1×N or 2×N configuration, fiber construction, input and output lengths, termination, splitter dimensions, host tray, optical limits, labels, quantity and schedule. Include a PON budget, BOM or drawing when available.
Applications
Bare Fiber PLC Splitter Applications
The host tray and enclosure define the allowable splitter dimensions, fiber routing, fixation and environmental protection. Confirm the complete installed assembly rather than selecting by compact size alone.
Splice Trays in Distribution Boxes
Match the splitter body and leads to the reserved tray area, splice-protector holders, fiber-storage route, bend control and cover clearance.
Fiber Splice Closures and Terminals
Install the bare splitter only in a closure or terminal that provides environmental sealing, body fixation, transition protection and enough tray capacity.
Custom Optical Modules and ODF Trays
Coordinate package dimensions, lead length, splice routing, labels and optical acceptance limits when integrating the splitter into a custom protected assembly.
