24 Fibers MMC Female Type 1 Fiber Loopback Module, OS2

Projects in the Philippines benefit from keeping the configuration, branch identification and installation requirement consistent across every participating site. The LPM-SM-24MMC loopback gives a 24-fiber OS2 optical self-test optical route through one MMC female APC connector. Type 1 mapping returns transmit lanes to the receive side for diagnostics and burn-in. Its 24-fiber MMC interface, 100mm loop and 250mm overall length make it suitable for controlled test environments where a compact multi-fiber loop is applicable.

Specifications

A 24-fiber loop is not a 16-fiber substitute

The additional fibers change the ferrule map and the lanes returned by the optical module. Validate that both the port and test practice are suited to 24 fibers and Type 1 wiring. The female MMC APC connector needs a compatible pinned mate; take care not to assume that a mechanically equivalent MMC interface guarantees the equivalent optical mapping.

Return loss and receiver conditions

This OS2 24-fiber configuration has 0.7dB maximum insertion loss and at least 40dB return loss. State its attenuation when assessing receiver operating conditions during the test. The optical module may help establish port electronics and diagnostic readings, but external optical path operation must still be measured with the intended trunk, adapters and equipment patch leads.

Care of the loop and connector

The loop measures 100mm with +0/-25mm tolerance and the complete item 250mm with +50/-0mm tolerance. Mating durability is 50 cycles. Respect the 7.5mm fiber bend minimum, avoid crushing the 2.5mm cable and review the multi-fiber end face before every 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 list unit count. If the optical module will be shared across numerous benches, order durable identification so it remains distinguishable from 16-fiber and OM4 loopbacks. Customers in the Philippines can include multi-site labeling or documentation requirements when requesting a project quotation.
