MMC-16 APC to 8 x LC UPC Harness Cable, 16 Fibers, OS2

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 connection.

Product Highlights

• MMC Female to LC UPC Duplex, 16 Fibers
• OS2 9/125µm, G.657.A1
• MMC insertion loss ≤0.35dB, return loss ≥60dB
• LC insertion loss ≤0.2dB, return loss ≥50dB
• Harness Polarity wiring scheme
• 2.5mm Plenum (OFNP) cable
• Standard length options: 1m (3ft), 2m (7ft), 3m (10ft)

The MMC end 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 an accurate loss budget for whichever duplex path is being tested.

Eight similar LC duplex connectors require clear identification. Match each leg to the intended transmit and receive ports and preserve harness polarity through the rest of the channel. The MMC connector is female and non-pinned; verify the pinned mating interface and APC compatibility before insertion. LC UPC ends must likewise connect to UPC, not APC, adapters.

Standard overall lengths are 1m (3ft), 2m (7ft) and 3m (10ft), with custom lengths in meters or feet. Place the fan-out where the LC legs can reach their ports without side loading. G.657.A1 fiber has a 10mm minimum bend radius, while the complete cable also has dynamic and static bend requirements that should be observed during dressing.

Order 16FMMCLCSMF with overall length and quantity, and include any LC leg-numbering scheme. For racks with multiple harnesses, customer-specific labels can tie each of the eight duplex legs directly to the port documentation.
