16 Fibers MMC Female Type 1 Fiber16 Fibers MMC Female Type 1 Fiber Loopback Module, OM4
New Zealand engineering teams can use the documented values below to compare the product with the intended channel and as-built requirements. This 16-fiber OM4 MMC loopback combines a female APC connector with Type 1 allocation for multimode optical port diagnostics. It loops transmit optical routes back to the receive side without requiring a remote device. G.657.A2 glass, a 100mm internal loop and a 250mm full item provide a compact tool for production, commissioning and fault-isolation work.

Matching the module to a multimode port
Use this loopback where the test setup explicitly calls for 16-fiber OM4 and Type 1 allocation. The MMC female APC interface must mate with the compatible pinned APC port. Although OM4 and OS2 versions may share a connector product line, their fiber characteristics differ; therefore, this loopback 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. Evaluate whether that attenuation is suitable for the transmitter and receiver under test. A successful loop may support port-operation checks and burn-in; a failed loop still requires systematic investigation of this loopback, connector cleanliness, allocation and active electronics.
Repeatable handling and cleanliness
This manufactured assembly is rated for 50 mating cycles and has a 2.5mm OFNP cable with a 7.5mm minimum optical-fiber bend radius. Take care never to use the short loop as a pull handle. Clean and review 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
Record LPM-OM4-16MMC for the 16-fiber OM4 Type 1 configuration, with quantity and intended test-kit tags. Submit the relevant equipment test allocation if there is any uncertainty; therefore, an alternative Type 2 project-specific module can be discussed instead. New Zealand project orders can include documentation and labeling requirements alongside the technical configuration.
