16 Fibers MMC Female Type 1 Fiber Loopback Module, OM4

Singapore high-density designs should assess this item together with panel access, cable routing and the complete optical loss allowance. This 16-fiber OM4 MMC loopback combines a female APC connector with Type 1 map for multimode optical port diagnostics. It loops transmit channels back to the receive side without requiring a remote device. G.657.A2 glass, a 100mm internal loop and a 250mm total product feature 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 map. The MMC female APC interface must mate with the specified pinned APC port. Although OM4 and OS2 versions may share a connector range, their fiber characteristics differ; consequently, the loopback assembly 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. Examine whether that attenuation is proper for the transmitter and receiver under test. A successful loop may support port-purpose checks and burn-in; a failed loop still requires systematic investigation of the loopback assembly, connector cleanliness, map and active electronics.
Repeatable handling and cleanliness
This optical 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 attempt to use the short loop as a pull handle. Clean and check 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
Document LPM-OM4-16MMC for the 16-fiber OM4 Type 1 variant, with quantity and correct test-kit markings. Give the active hardware test map if there is any uncertainty; consequently, an alternative Type 2 customized module may also be discussed instead. Singapore and regional project orders can be reviewed for interface compatibility, packing details and delivery coordination.
