Purpose-Built Optical Return Path for Equipment Testing
BWN-LB-SC-MM is a passive SC/UPC duplex loopback for equipment checks using the specified OM1 or OM2 multimode configuration. State the required fiber grade in the inquiry so the configuration can be matched to your equipment.
Use this model where the equipment calls for an SC/UPC duplex multimode return path. Match the connector polish, selected fiber grade and optical limits to the equipment documentation; an SC port alone does not establish compatibility.
Connector: SC/UPC duplexInterface selected for the specified optical equipment and test port.
Fiber: OM1 / OM2 multimodeInternal fiber type matched to the intended optical interface.
Insertion Loss: ≤ 1.0 dB @ 850 nmPublished insertion-loss limit for this model. Request the applicable test conditions and test-record availability for the ordered configuration.
Return Loss: N/ANo return-loss value is stated for this multimode model. If your acceptance specification requires a return-loss limit, request confirmation for the ordered configuration.
Typical Applications
- Legacy multimode telecom and enterprise testing
- Multimode SC port verification
- Field maintenance and troubleshooting
- Production quality control
Use note: This passive loopback supports port-level checks. It does not replace a calibrated optical power meter or certify an installed fiber link.
Why Source Fiber Loopbacks from BWNFiber?
- Optical acceptance: request the agreed loss limit, test wavelength, inspection scope and available test-record format before order approval.
- Sample evaluation: verify the loopback with your target equipment before moving to a larger order.
- Project identification: discuss labeling, packaging and traceability requirements for deployment or production use.
- Configuration review: share the equipment model, interface and channel requirements for an application-level check.
Want to Test Before You Commit?
Send the target equipment model and quantity to request a sample, configuration review, datasheet or bulk quotation.
FAQ
Frequently Asked Questions
What does the SC/UPC Multimode Fiber Optic Loopback test?
It routes transmitted optical power back to the receive path so connected equipment can run supported port checks, alarms and diagnostic routines. The loopback is passive and does not create a measurement result by itself.
How do I confirm compatibility before ordering?
Confirm an SC/UPC duplex interface, the required OM1 or OM2 fiber, and the transmit-to-receive connection for your equipment. Check the operating wavelength, receiver input limits and supported diagnostic procedure. Ask for a configuration review if additional attenuation is required.
Can I request samples before a bulk order?
Yes. Include the target equipment, expected quantity and any labeling or packaging requirements so the sample configuration can be reviewed before shipment.
Can labeling and packaging be customized?
Project-specific identification and packaging can be discussed. Provide your labeling format, traceability requirements and packing quantities for review.
