MPO To 4 LC Duplex Breakout Cable

Specified build: one female UPC multi-fiber end, four LC UPC duplex Uniboot ends, 30 m OM4 trunk.

One Trunk Route, Four Duplex Destinations

30 m OM4 · 8 fibers · 1 MPO-compatible MTP®-8 female · 4 LC duplex Uniboot · Type B · OFNP

Run the shared cable along the main pathway, then distribute its numbered LC branches at the equipment end. The 2.0 mm fanout legs help organize the final connections without routing four separate duplex cables along the full distance.

Construction illustration: two sheath layers around the fiber assembly, with aramid reinforcement.

Separate the Trunk Path from the Final Fanout

The common trunk keeps the eight fibers together along the longer section of the installation. Inner and outer jackets surround the reinforced fiber assembly before it transitions into the end breakouts.

The double sheath adds physical protection compared with a similar single-sheath construction. No numerical crush rating is specified here, so the cable still needs suitable pathway support and protection from tight clamps or tray edges.

Set out the breakout locations before installation: the specified transition lengths are 0.84 m at the MTP® end and 0.91 m at the LC end. Include the connector access space when checking whether each end will reach its ports.

Reference cross-section; layer dimensions are illustrative and are not a manufacturing drawing.

Route the Finished Cable to Its Own Bend Limits

The 7.5 mm minimum radius belongs to the glass fiber. For the assembled cable, use 20 times its outside diameter while moving it and 10 times its diameter once installed.

For the published 3.6–4.5 mm main-cable range, those factors correspond to 72–90 mm during movement and 36–45 mm at rest. Confirm the delivered OD and any separate fanout-leg routing requirements with the order drawing.

Long-term and short-term tensile ratings are 100 N and 300 N respectively. Plan the installation load through the cable support method rather than through the LC latches or the multi-fiber connector housing.

The LC end has four duplex connectors, numbered 1–4. Each duplex body contains two optical ferrules.

Keep Each Pair Together at the Equipment End

A duplex Uniboot termination carries the two fibers of a branch through one compact cable entry. Four such terminations account for all eight fibers in this assembly; the branch numbers identify the four physical endpoints.

Allocate one duplex branch to each intended duplex optical connection. Attach the cabinet and port identifiers to the cable schedule so technicians can locate an individual pair without disturbing the other three.

The specified assembly is Type B. Confirm the complete MPO-position-to-LC-pair drawing and the transmit/receive assignment before installation; branch number alone does not establish which LC ferrule is Tx or Rx.

Generic US Conec MTP® component illustration. Male and female alternatives are shown; this order uses one female Base-8 end.

Match the Female UPC End to the Correct Port

The multi-fiber ferrule, housing key and retention parts form the MPO-compatible connection. Spring components support the ferrule inside the housing, with the rear crimp and boot completing the cable transition.

The selected female end has guide holes rather than projecting alignment pins. It requires a compatible pinned UPC mating interface. The alternative male pin hardware in the exploded view is not an extra connector supplied with this cable.

Verify the cassette or adapter interface, including gender and orientation, before ordering. The number of fibers populated in this Base-8 assembly comes from its configuration record, not from the generic component drawing.

Carry Four Duplex Connections Between Distribution Areas

The illustrated route places the common trunk between two cabinet areas. A compatible cassette presents the multi-fiber connection on one side, and four LC duplex branches reach the selected equipment ports on the other.

Select the cassette wiring and pinned UPC interface for this female cable end. The four LC branches provide separate optical paths; the drawing depicts duplex interconnection rather than a guarantee of SR4 lane breakout.

Equipment labels and speed examples in the reference topology describe that illustrated arrangement. Confirm your own module type, port configuration and channel budget before adopting a similar layout.
