For UAE project teams, the key is to match this exact configuration to the port schedule, optical budget and delivery documentation. The LPM-SM-24MMC loopback offers a 24-fiber OS2 optical self-test route through one MMC female APC connector. Type 1 map returns transmit lanes to the receive side for diagnostics and burn-in. Its 24-fiber MMC interface, 100mm loop and 250mm total length make it suitable for controlled test environments where a compact multi-fiber loop is necessary.

• Fiber Count: 24 Fibers
• Fiber Mapping: Type 1

Specifications

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

The extra fibers change the ferrule mapping and the lanes returned by this module. Verify that the two the port and test process are intended for 24 fibers and Type 1 wiring. The female MMC APC connector needs a compatible pinned mate; do not assume that a from a mechanical standpoint comparable MMC interface guarantees the identical optical map.

Return loss and receiver conditions

This OS2 24-fiber version has 0.7dB maximum insertion loss and at least 40dB return loss. Provide its attenuation when assessing receiver operating conditions during the test. This module may help confirm 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. Preserve 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 state unit count. If this module will be shared across multiple benches, specify durable identification so it remains distinguishable from 16-fiber and OM4 loopbacks. Our UAE project support can review the requirement with Shenzhen production before a formal quotation is issued.
