24 Fibers MMC Female Type 1 Fiber Loopback Module, OS2
For Pakistani procurement and engineering teams, the specification provides a practical basis for checking compatibility before production is requested. The LPM-SM-24MMC loopback includes a 24-fiber OS2 optical self-test route through one MMC female APC connector. Type 1 layout returns transmit lanes to the receive side for diagnostics and burn-in. Its 24-fiber MMC interface, 100mm loop and 250mm entire length make it suitable for controlled test environments where a compact multi-fiber loop is project-specific.

A 24-fiber loop is not a 16-fiber substitute
The supplementary fibers change the ferrule allocation and the lanes returned by this test module. Make certain of that the two the port and test process are created for 24 fibers and Type 1 wiring. The female MMC APC connector needs a compatible pinned mate; make sure not to assume that a from a mechanical standpoint comparable MMC interface guarantees the identical optical layout.
Return loss and receiver conditions
This OS2 24-fiber version has 0.7dB maximum insertion loss and at least 40dB return loss. Specify its attenuation when assessing receiver operating conditions during the test. This test module can help review port electronics and diagnostic readings, but external connection behavior must still be measured with the intended trunk, adapters and hardware patch cords.
Care of the loop and connector
The loop measures 100mm with +0/-25mm tolerance and the entire unit 250mm with +50/-0mm tolerance. Mating durability is 50 cycles. Maintain the 7.5mm fiber bend minimum, avoid crushing the 2.5mm cable and examine the multi-fiber end face before each insertion to prevent debris from being transferred to the port.
Ordering and Factory Support
Order LPM-SM-24MMC for 24-fiber OS2 Type 1 testing, and indicate number of units. If this test module will be shared across many benches, specify durable identification so it remains distinguishable from 16-fiber and OM4 loopbacks. For Pakistan, a clear port or maintenance schedule helps us confirm the correct factory-built configuration before supply.
