For Nigerian deployments, this product should be evaluated as part of the complete network path, including its connectors, mapping and acceptance values. This OM4 MMC-to-LC harness fans one MMC-16 APC female connector out to eight LC UPC duplex legs. Sixteen bend-insensitive multimode fibers provide eight duplex paths for switches, servers or patch panels. While assembled at the factory LC branches eliminate the need for an individual multimode cassette, the single 2.5mm plenum trunk keeps the main route compact.

Direct fan-out for multimode equipment
The fan-out harness is suitable when a MMC-based parallel interface must connect to LC duplex hardware using OM4. It does not itself perform electronic conversion or change lane speeds; it provides the passive fiber assignment only. Establish that the active port expects this breakout arrangement and that each LC leg is assigned to the matching duplex destination.
MMC and LC optical values
Maximum insertion loss is 0.35dB at MMC and 0.2dB at LC. Minimum return loss is 40dB for the MMC APC interface and 30dB for LC UPC. OM4 attenuation is 2.3dB/km at 850nm and 0.6dB/km at 1300nm. Use these figures with the transceiver budget and other connections to assess every whole duplex link.
Managing eight LC duplex branches
Specify stock length choices of 1m (3ft), 2m (7ft) or 3m (10ft), or request project-specific meter and foot lengths. Eight branch pairs need orderly routing to prevent crossed transmit and receive connections. Label the legs before bundling, support the fan-out body body and keep the 7.5mm minimum fiber bend radius near the connector interfaces.
Ordering and Factory Support
Specify 16FMMCLCOM4 with the needed length and quantity. Supply your preferred LC branch identifiers and MMC label data; the factory might align these markings with the rack’s duplex-port numbering to simplify future moves and troubleshooting. For Nigerian orders, our team can check the requirement before coordinating manufacture and international delivery.
