MMC-16 APC to 8 x LC UPC Harness CableMMC-16 APC to 8 x LC UPC Harness Cable, 16 Fibers, OS2
Singapore high-density designs should assess this item together with panel access, cable routing and the complete optical loss allowance. 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 link.

Eight duplex legs with separate connector budgets
The MMC connector interface 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 distinct in the specification allows engineers build a well-defined link budget for whichever duplex channel is being tested.
Port mapping at the LC side
Eight analogous LC duplex connectors require distinct identification. Match each branch to the intended transmit and receive ports and retain harness polarity through the rest of the path. The MMC connector is female and non-pinned; make sure of 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 total lengths are 1m (3ft), 2m (7ft) and 3m (10ft), with lengths built to order in feet or meters. Place the cable fan-out where the LC legs may reach their ports without side loading. Whereas the full cable additionally has dynamic and static bend specifications that should be observed during dressing, G.657.A1 fiber has a 10mm minimum bend radius.
Ordering and Factory Support
Order 16FMMCLCSMF with total length and quantity, and give any LC leg-numbering scheme. For racks with several harnesses, customer-specific markings may tie each of the eight duplex legs directly to the port documentation. Singapore and regional project orders can be reviewed for interface compatibility, packing details and delivery coordination.
