For UAE project teams, the key is to match this exact configuration to the port schedule, optical budget and delivery documentation. This 16-fiber OM4 MMC loopback combines a female APC connector with Type 1 map for multimode optical port diagnostics. It loops transmit routes back to the receive side without requiring a remote device. G.657.A2 glass, a 100mm internal loop and a 250mm total unit offer a compact tool for production, commissioning and fault-isolation work.

Specifications

Matching the module to a multimode port

Use this loopback where the test setup explicitly calls for 16-fiber OM4 and Type 1 map. The MMC female APC interface must mate with the proper pinned APC port. Because although OM4 and OS2 versions may share a connector series, their fiber characteristics differ, this module should be labeled and stored distinctly in the test kit.

Using insertion loss in the test setup

The passive loop introduces up to 0.7dB insertion loss and has at least 60dB return loss. Review whether that attenuation is suitable for the transmitter and receiver under test. A successful loop may support port-role checks and burn-in; a failed loop still requires systematic investigation of this module, connector cleanliness, map and active electronics.

Repeatable handling and cleanliness

This assembly is rated for 50 mating cycles and has a 2.5mm OFNP cable with a 7.5mm minimum optical-fiber bend radius. Do not use the short loop as a pull handle. Clean and examine the ferrule before insertion, cap it after testing and keep the 100mm loop free from sharp edges or tightly weighted cable bundles.

Ordering and Factory Support

State LPM-OM4-16MMC for the 16-fiber OM4 Type 1 model, with unit count and necessary test-kit identifiers. Provide the active equipment test map if there is any uncertainty, so an alternative Type 2 customized module may be discussed instead. Our UAE project support can review the requirement with Shenzhen production before a formal quotation is issued.
