1×2 80/20 PLC Splitter with 250 µm Leads and No Connectors

BWN-PLC-MMST-1X2-NA-0.25-U8020

Model: BWN-PLC-MMST-1X2-NA-0.25-U8020

This model divides one single-mode optical input into two unequal target paths: 80% and 20%. It uses G.657A1 250 µm unterminated leads, an input/output lead length of at least 1.0 m, and a compact 40×4×4 mm body. Specify it only after confirming the host tray or closure, port identification and the allowable loss for both routes.

Primary CTA: Request model confirmation and a quotation. Send the model, quantity, host tray or closure, required port labels, both path budgets and the document pack you need.

Quick specification answer

BWN-PLC-MMST-1X2-NA-0.25-U8020 is a 1×2 unequal PLC splitter for projects that require one 80% target output and one 20% target output. The supplied model record lists a 1260–1650 nm operating window, G.657A1 250 µm leads, no connectors, at least 1.0 m lead length and a 40×4×4 mm body. Use the exact model limits—not generic 1×2 values—when closing the optical budget.

Key configuration

• 1 input × 2 unequal outputs
• Target split: 80% / 20%
• G.657A1 single-mode fiber, 250 µm coating
• Unterminated leads; no factory connectors on this SKU
• Input/output lead length: ≥1.0 m on the supplied unit record
• Body: 40×4×4 mm
• Operating wavelength: 1260–1650 nm
• Operating and storage temperature listed on the supplied unit record: −40 °C to +85 °C

The target percentage describes the intended optical-power distribution. It does not replace the insertion-loss limits or the complete route budget.

Model-specific technical specifications

Port map and maximum optical limits

* Values transcribed from the supplied model/unit record. Engineering/QA must approve the controlled specification before publication or contractual use.

Do not identify the 80% and 20% outputs by fiber position, color or assumed routing. Use the approved port label and the report associated with the order. Reversing the two outputs can invalidate the local and downstream path budgets.

Sample-unit measurement record

The supplied first-party image shows one physical unit together with a serial-specific data/test sheet. The following values describe that photographed unit; they are not a guarantee for every production unit.

For purchasing or acceptance, use the approved maximum limits and the report tied to the ordered unit or batch. Do not budget from a sample's measured minimums.

Application and compatibility conditions

This configuration can be evaluated for a protected splice-tray or closure design where one route needs the higher-power output and another route uses the lower-power tap. Approval depends on the complete design, including:

1. the host's available 40×4×4 mm body space and fixation method;
2. routing and protection for 250 µm fibers and stored service slack;
3. an unambiguous input/80%/20% label plan;
4. the maximum allowable loss on both routes, including connectors, splices, fiber, other passive components and engineering margin;
5. the required wavelength plan and active-equipment limits; and
6. the report, drawing and acceptance criteria specified in the purchase order.

The 1260–1650 nm operating range is a device attribute. It does not by itself prove end-to-end compatibility with a particular OLT, ONT, monitoring receiver, PON class or network topology.

How to select and release this model

1. Freeze the ratio and port roles. Confirm that the design requires an 80% higher-power path and a 20% lower-power path—not a 50/50 1×2 splitter.
2. Close both path budgets. Use 1.60 dB for the 80% path and 8.50 dB for the 20% path as the provisional model maximums, pending the approved controlled datasheet.
3. Confirm the host. Provide the tray or closure drawing, usable internal dimensions, fixation method, fiber route and splice-protector locations.
4. Confirm lead construction and length. This SKU is documented with 250 µm G.657A1 leads and at least 1.0 m length. Confirm whether the order needs separate input/output lengths.
5. Define port identification. State the labels and route assignment for input, 80% output and 20% output.
6. Define evidence and acceptance. State whether the order requires a controlled datasheet, drawing, serial or batch report, label photo, packaging record or other release document.

Differences from related products

These are selection boundaries, not proof that one technology or package is universally better.

Use cases and non-fit conditions

Potential fit, subject to engineering approval:

• a protected tray or closure with direct fusion-splice interfaces;
• an unequal branch where both route budgets have been calculated using the exact port limits;
• a build that can safely route and protect 250 µm leads; and
• an order that requires model-level optical evidence rather than generic family values.

Do not select this SKU when:

• an equal 50/50 split is required;
• factory connectors or a plug-in module are required;
• the host cannot protect 250 µm leads or secure the compact body;
• the 20% path cannot tolerate the specified maximum insertion loss;
• the package-family requirement excludes the approved construction; or
• the project expects standards/certification evidence that has not been confirmed for this model.

Evidence and quality-control requirements

The supplied image demonstrates that one unit was recorded at 1310, 1490 and 1550 nm for IL and PDL, with RL recorded as passing above 55 dB. Before a purchase order is released, define the evidence required for the actual order. Recommended acceptance fields are:

• model and revision;
• serial or batch identifier;
• input/80%/20% port mapping;
• approved maximum IL and PDL at the required wavelengths;
• RL/directivity acceptance limits;
• fiber type, coating diameter and lead lengths;
• body dimensions and package-family classification;
• connector status;
• test method/equipment/conditions, if contractually required; and
• disposition and retest record for any exception.

BWNFiber should not publish a universal testing or certification claim for this SKU until QA approves the supporting process records.
