MMC-16 APC to 8 x LC UPC Harness Cable, 16 Fibers, OS2
For Tanzanian site work, correct product selection should be followed by careful transport, connector inspection and retention of the fiber records. The 16FMMCLCSMF harness connects one MMC-16 APC female interface to eight LC UPC duplex connectors over OS2 fiber. All sixteen fibers are exposed as eight duplex pairs, providing a direct single-mode fan-out between MMC infrastructure and LC-based equipment or panels. This removes the intermediate cassette that would otherwise add hardware and another mated interface.

Eight duplex legs with separate connector budgets
The MMC connector side is rated at 0.35dB maximum insertion loss and 60dB minimum return loss. Each LC UPC interface is specified at 0.2dB maximum insertion loss and 50dB minimum return loss. Keeping the two connector types separate in the specification helps engineers build a faithful optical link budget for whichever duplex route is being tested.
Port mapping at the LC side
Eight comparable LC duplex connectors require explicit identification. Match each of the legs to the intended transmit and receive ports and preserve harness polarity through the rest of the link. The MMC connector is female and non-pinned; cross-check the pinned mating interface and APC compatibility before insertion. LC UPC ends must likewise connect to UPC, not APC, adapters.
Length, fan-out position and fiber care
Standard overall lengths are 1m (3ft), 2m (7ft) and 3m (10ft), with bespoke lengths in feet or meters. Place the branch point where the LC legs can reach their ports without side loading. G.657.A1 fiber has a 10mm minimum bend radius, whereas the complete cable further has dynamic and static bend needs that must be observed during dressing.
Ordering and Factory Support
Order 16FMMCLCSMF with overall length and number of units, and set out any LC leg-numbering scheme. For racks with various harnesses, customer-specific identifiers can tie each of the eight duplex legs directly to the port documentation. For Tanzanian deliveries, the order details should include any site identification needed by the installation team.
