1×3 Unbalanced PLC Splitter, 70/15/15, SC/APC ABS, 3 m

BWNF-PLC-ABS-1×3-70-30-SCAPC-3M

Proposed model: BWNF-PLC-ABS-1×3-70-30-SCAPC-3M — TBC: formal SKU-to-report mapping required

This 1×3 unbalanced PLC splitter has one input, one nominal 70% output and two nominal 15% outputs in a protected ABS module. The supplied build record identifies G657A fiber, 3.0 mm × 3 m pigtails, SC/APC terminations and a 1260–1650 nm operating window. Use the model-specific port map and approved optical limits; do not substitute an equal-split 1×3 table or a 1×3 FBT coupler.

Browse the broader cassette PLC splitter family, review PLC splitter selection fields, or return to the fiber optic splitter product directory when this exact build does not match the requirement.

Primary CTA — Request a model and test-record review: Send the target topology, required port assignment, loss budget, host enclosure, quantity and delivery location. BWNFiber will return the proposed model mapping, available drawing/datasheet, model-specific acceptance limits and quotation status after internal confirmation.

What Does 70/30 Mean on This 1×3 Model?

For the photographed build, 70/30 is a shorthand for three outputs: output 1 is marked 70%, while outputs 2 and 3 are each marked 15%. The two tap outputs therefore share the remaining 30%. This interpretation is specific to the supplied report and physical labels; it should not be assumed for another 1×3 splitter without its approved port map.

The optical budget must use loss values, not nominal percentages alone. The network designer must add fiber, splice, connector, splitter and engineering-margin losses for every complete path and compare the result with the approved OLT/ONU or equipment power limits.

Verified Configuration of the Photographed Build

Measured Serial Example at 1310 and 1550 nm

The supplied Final Test Report records the following measurements for serial PLC1*320240 95461. These are traceability data for that photographed build, not universal limits for every unit or a substitute for the approved model specification.

Before publication or PO release, QA must confirm the measurement scope, equipment/method, calibration traceability, whether connector loss is included, the applicable acceptance limits and whether the serial may be shown publicly.

Where This Splitter Fits

This configuration may fit a designed optical-distribution route that needs one higher-share continuation path and two lower-share local branches. The network diagram must identify the intended role of every output and prove that all resulting paths remain inside the equipment power budget.

Do not select this model only because 70/30, 1×3 or SC/APC appears in a BOM. Also confirm:

• PLC rather than FBT technology;
• the 70/15/15 port convention and physical labels;
• operating wavelength and required optical limits;
• G657A fiber and 3.0 mm × 3 m pigtails;
• connector family and APC polish at every mating interface;
• ABS-module dimensions, cable exits and routing clearance;
• the complete end-to-end optical budget and required margin.

Non-fit conditions

Do not use this page to approve:

• an equal-split 1×3 or 1×4 design;
• a 1×3 FBT coupler selected for a different wavelength window or coupling function;
• a design that requires a different connector, fiber grade, tail diameter/length or enclosure;
• a path that has not been checked against model-specific loss limits;
• a compliance or environmental requirement that is not covered by the approved product packet.

PLC and FBT Are Not Interchangeable Labels

BWNFiber already publishes a separate 1×3 FBT product with overlapping SC/APC, 3.0 mm, 3 m and 70:30 ordering language. That does not make it a direct substitute for this proposed PLC model. Release either item only after the BOM identifies the technology, wavelength requirement, output convention, path-specific optical limits, package and test evidence.

For a technology comparison, use the dedicated PLC-vs-FBT guide. This page is limited to the exact proposed PLC configuration.

The existing 1×3 SC/APC FBT splitter record remains a separate technology-specific product page.

How to Validate the Model Before an RFQ or Purchase Order

1. Fix the identity. Confirm the commercial SKU, factory part number and revision on the same approved record.
2. Fix the port map. Mark IN, 70%, 15% and 15% on the drawing and physical labels.
3. Close every path budget. Use the approved maximum loss for each output, plus fiber, connector, splice and margin assumptions.
4. Confirm the interface. Match SC/APC with the mating adapters and patch cords; do not mix APC and UPC interfaces.
5. Confirm mechanical fit. Check the module envelope, tail exits, routing space and bend control in the intended box or cabinet.
6. Define acceptance evidence. State whether the order requires a datasheet, drawing, serial report, label sample, end-face record or other inspection file.
7. Freeze the PO description. Put the exact ratio convention, port labels, fiber, tail, connector, package, optical limits, quantity and revision on the order.

RFQ Input Checklist

Send the following information:

• proposed model or reference part number;
• network diagram and the role of the 70% and 15% paths;
• operating wavelengths and equipment optical classes;
• maximum allowed loss for each complete path and required margin;
• 1×3, 70/15/15 output assignment;
• G657A requirement, including subtype if required;
• 3.0 mm pigtail diameter and 3 m length, or approved alternatives;
• SC/APC on input and all outputs;
• ABS module envelope and host-enclosure constraints;
• required drawing, datasheet, serial test report and label format;
• quantity, sample requirement, delivery location and target schedule.

Secondary CTA — Request the product packet: Ask for the approved SKU mapping, drawing/datasheet, model acceptance table and available serial-level test documentation before a sample or batch PO.
