1×2 90/10 Unbalanced Bare-Fiber PLC Splitter, 250 µm, Unterminated

BWN-PLC-MMST-1X2-NA-0.25-U9010

90/10 configuration at a glance

The BWN-PLC-MMST-1X2-NA-0.25-U9010 is a 1×2 unbalanced PLC splitter with nominal 90% and 10% output paths. The inspected build uses G.657.A1 250 µm unterminated leads, no connectors, a compact 40 × 4 × 4 mm package and lead lengths recorded as at least 1.0 m.

The two outputs must be budgeted separately. The ratio identifies nominal power distribution; it is not an insertion-loss value, and balanced 50/50 limits must not be substituted for this model.

Recorded configuration

Port-specific optical limits

The photographed sample recorded 90% path insertion loss of 1.18, 1.00 and 1.13 dB at 1310, 1490 and 1550 nm. The 10% path recorded 11.26, 11.18 and 11.24 dB. These are sample-specific readings, not universal guaranteed values. Use the approved purchase specification and the report tied to the delivered unit or lot for acceptance.

Integration and selection checks

• Confirm the physical 90% and 10% output labels before splicing.
• Calculate both paths with connector, splice, fiber and engineering margins.
• Verify the 40 × 4 × 4 mm package and lead routing against the host tray or enclosure.
• Protect the unterminated 250 µm leads with suitable routing, bend control and environmental protection.
• State the ratio, lead construction, length, quantity, destination and document requirements in the RFQ.
