Fiber Loopbacks

Projects in the Philippines benefit from keeping the configuration, branch identification and installation requirement consistent across every participating site. Here you will find fiber loopback modules for transceiver verification: duplex LC and SC loopbacks, attenuated 3dB versions, MTP/MPO loopbacks on OS2 and OM4, and MMC loopbacks for space-efficient interfaces.

For projects in the Philippines, keep the loopback design consistent across sites that share one hardware standard so test records stay comparable.

Review the ferrule before every insertion and cap the optical module immediately after use; single-mode testing is unforgiving about contamination.

Placing an Order and Factory Support

Every loopback module is optically tested before packing and ships with its dust cap fitted. When submitting the order, refer to the optical module by connector interface, fiber count, polish and attenuation; for other attenuation values, mapping types or connector combinations, send the test need with the inquiry and the factory will validate the manufacturable specification. Customers in the Philippines can include multi-site labeling or documentation requirements when requesting a project quotation.
