24 Fibers MMC Female Type 1 Fiber24 Fibers MMC Female Type 1 Fiber Loopback Module, OS2
New Zealand engineering teams can use the documented values below to compare the product with the intended channel and as-built requirements. The LPM-SM-24MMC loopback provides a 24-fiber OS2 optical self-test optical route through one MMC female APC connector. Type 1 allocation returns transmit lanes to the receive side for diagnostics and burn-in. Its 24-fiber MMC interface, 100mm loop and 250mm full length make it suitable for controlled test environments where a compact multi-fiber loop is intended.

A 24-fiber loop is not a 16-fiber substitute
The added fibers change the ferrule assignment and the lanes returned by this loopback. Cross-check that the two the port and test practice are specified for 24 fibers and Type 1 wiring. The female MMC APC connector needs a compatible pinned mate; take care never to assume that a from a mechanical standpoint alike MMC interface guarantees the matching optical allocation.
Return loss and receiver conditions
This OS2 24-fiber configuration has 0.7dB maximum insertion loss and at least 40dB return loss. Submit its attenuation when assessing receiver operating conditions during the test. This loopback may help ensure port electronics and diagnostic readings, but external optical path behavior must still be measured with the intended trunk, adapters and hardware patch leads.
Care of the loop and connector
The loop measures 100mm with +0/-25mm tolerance and the full item 250mm with +50/-0mm tolerance. Mating durability is 50 cycles. Retain the 7.5mm fiber bend minimum, avoid crushing the 2.5mm cable and review 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 record quantity. If this loopback will be shared across multiple benches, specify durable identification so it remains distinguishable from 16-fiber and OM4 loopbacks. New Zealand project orders can include documentation and labeling requirements alongside the technical configuration.
