Description

MTP-8 to 4 x LC UPC Harness, 8 Fibers, OM4, Type B

Factory-terminated MTP-8 (UPC) to 4× LC UPC duplex breakout harness for high-density multimode optical interconnects inside data centers. The OM4 multimode MTP connector on one end breaks out to four LC UPC duplex legs on the other end, mapping an 8-fiber (Base-8) channel with Type B (crossover) polarity. The assembly uses bend-insensitive OM4 fiber (50/125 µm) under LSZH jacket and is 100% factory tested, ready for direct plug-in between OM4 MTP trunk cables and LC switch ports in 40G/100G/400G parallel optics deployments.

MTP-8 to 4 × LC UPC Harness, 8 Fibers, OM4, Type B — factory-terminated multimode breakout assembly with violet LSZH jacket

Key Features

  • Base-8 OM4 breakout: one MTP-8 connector breaks out to 4× duplex LC UPC legs, ideal for SR4 parallel optics migration.
  • Type B (crossover) polarity: standard polarity for direct connection between MTP cassettes at both ends of a link.
  • Low insertion loss: MTP ≤ 0.35 dB typical; LC UPC ≤ 0.2 dB typical, fully interchangeable 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 up to 150 m @ 100G.
  • 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

  • 40G SR4 / 100G SR4 / 400G SR4.2 parallel optics breakout
  • Hyperscale spine-leaf architecture with multimode OM4 backbone
  • MPO/MTP cassette to LC patch panel fan-out
  • QSFP / QSFP28 / QSFP-DD transceiver fan-out inside racks
  • Multimode OM4 backbone links in enterprise equipment rooms
