Purpose-Built Optical Return Path for Equipment Testing
The BWNFiber SC/UPC OM4 Fiber Optic Loopback is designed for higher-bandwidth multimode SC applications. It meets the performance needs of modern multimode networks requiring OM4 fiber.
The SC duplex interface is suited to telecom, access-network, enterprise and laboratory equipment that uses SC optical ports. Its internal OM4 multimode path supports repeatable port checks while reducing the number of loose patch cords in the test setup.
Connector: SC/UPC duplexInterface selected for the specified optical equipment and test port.
Fiber: OM4 multimodeInternal fiber type matched to the intended optical interface.
Insertion Loss: ≤ 1.0 dB @ 850 nmFactory-tested optical loss limit for the finished loopback assembly.
Return Loss: N/ASpecified reflected-power performance for the singlemode optical path.
Typical Applications
- High-performance multimode SC testing
- Data center and enterprise multimode verification
- Field maintenance and production QA
- Laboratory optical testing
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?
- 100% optical testing: finished assemblies are checked against the stated optical requirements before shipment.
- 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 OM4 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?
Check the connector interface, fiber type, optical power range and test method. For MPO products, also confirm gender, pin configuration, polarity, fiber count and TX/RX channel mapping.
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.
