1×2 85/15 Unbalanced Bare-Fiber PLC Splitter, 250 µm, Unterminated

BWN-PLC-MMST-1X2-NA-0.25-U8515

Model BWN-PLC-MMST-1X2-NA-0.25-U8515 is a single-mode 1×2 unequal PLC splitter with nominal 85% and 15% outputs, G.657.A1 250 µm leads, no connectors and a 40 × 4 × 4 mm package. Use the exact model limits and approved physical port map—not the nominal ratio alone—when checking a tray, closure or optical route.

Quick answer

This is an exact-SKU record for a 1×2 85/15, 250 µm, unterminated PLC splitter—not a generic 1×2 selection guide. The supplied model sheet states a 40 × 4 × 4 mm package and separate insertion-loss limits for the nominal 85% and 15% outputs. Approval still requires the controlled port map, host-tray fit and complete route budget.

Primary action: Request the current model datasheet, dimensional/port-map drawing and model-matched test-record format.
Secondary action: Send the host-tray drawing and route budget for a configuration-gap review.

Exact configuration and model limits

Optical limits shown on the supplied model sheet

These are model-sheet limits supplied for the reviewed build. Confirm the current controlled datasheet revision, test conditions and whether any finished assembly interfaces are included before using them as acceptance limits.

Sample test record

The supplied photo records serial 25120100002, inspected on 2025-12-14. The values below describe that sample only; they are not a promise that every production unit will have identical measurements.

Before release, ask for the agreed production or batch test record and confirm the measurement method, reference method, instrument, calibration status, wavelengths and pass/fail limits.

Application and compatibility conditions

This compact, unterminated build can be considered for a protected splice tray, closure or custom module when all of the following are confirmed:

1. The approved drawing identifies the input, nominal 85% output and nominal 15% output on the physical leads.
2. The 40 × 4 × 4 mm package, fiber exits, service slack and splice protectors fit the host tray without pinching, crushing or crossing a moving cover or hinge.
3. The enclosure provides the mechanical and environmental protection that the bare 250 µm leads and compact device require.
4. Every route passes the project’s maximum-loss and minimum-loss/receiver-input checks using model- and condition-matched values.
5. The network owner or qualified designer approves the topology, equipment limits, wavelengths, direction and acceptance method.

An 85/15 label does not by itself approve a GPON, XGS-PON or other route. It describes nominal power distribution, while the finished device’s insertion-loss limits and the complete route budget control compatibility.

How this model differs from related splitter options

What to confirm before ordering

• Approved commercial SKU, factory P/N and document revision.
• Controlled drawing with the physical input/85%/15% port map and lead labels.
• Maximum and, where required, minimum input-to-output loss by wavelength and direction.
• Whether the specified loss includes connectors, adapters, splices or no added interfaces.
• Host tray/closure dimensions, fixation, fiber routing, bend control, splice storage and cover clearance.
• Required sample, first-article, batch or unit test scope and report format.
• Label, serial/lot, packaging and change-notification requirements.
• Required compliance documents for the exact model and destination; none are claimed on this draft without model-level evidence.
