Description

MTP-16 APC to 8 x LC UPC Harness, 16 Fibers, OM4, Crossover

Factory-terminated MTP-16 APC to 8× LC UPC duplex breakout harness for high-density multimode OM4 data center interconnects. The OM4 multimode MTP-16 connector on one end breaks out to eight LC UPC duplex legs on the other end, giving a 16-fiber (Base-16) channel mapped with Crossover (Type B inverted) polarity. The assembly uses bend-insensitive OM4 fiber (50/125 µm) under LSZH jacket and is 100% factory tested for insertion loss and return loss, ready for direct plug-in between Base-16 OM4 MTP trunk cables and LC switch ports or patch panels.

MTP-16 APC to 8 × LC UPC Harness, 16 Fibers, OM4, Crossover — Base-16 factory-terminated breakout assembly with violet LSZH jacket

Key Features

  • Base-16 OM4 breakout: one MTP-16 connector breaks out to 8× duplex LC UPC legs, enabling 400G/800G SR4.2 and OM4 parallel optics deployments.
  • Crossover (Base-16) polarity: inverted Type B mapping for direct connection between MTP cassettes at both ends.
  • Low insertion loss: MTP-16 ≤ 0.35 dB typical; LC UPC ≤ 0.2 dB typical per IEC 61753-1 Grade B.
  • High return loss: UPC end ≥ 30 dB multimode per IEC 61300-3-4.
  • OM4 bend-insensitive fiber: 50/125 µm OM4 with 7.5 mm minimum bend radius, optimized for 850 nm VCSEL transmission.
  • LSZH jacket (violet): OFNR-rated violet jacket per TIA-568.3-E OM4 color code.
  • 100% factory tested: insertion loss and endface geometry per IEC 61300-3-35; test report shipped with each assembly.

Applications

  • 400G SR4 / 800G SR4.2 multimode parallel optics breakout
  • Hyperscale spine-leaf architecture with multimode OM4 backbone
  • MPO/MTP cassette to LC patch panel fan-out
  • QSFP-DD / OSFP transceiver fan-out to LC ports
  • Multimode OM4 backbone links in enterprise equipment rooms
