Product Overview
DIMI 24 Fiber MPO-24 UPC to 12× LC Duplex UPC OM4 Breakout Cable converts one high-density 24-fiber MPO interface into twelve independent LC duplex connections. It is designed for data center distribution, Base-24 infrastructure migration and equipment-side fiber fanout.
Built with OM4 50/125 μm multimode fiber, the assembly combines one MPO-24 / MTP-24 connector with twelve LC duplex branches. MPO gender, polarity, main cable length, fanout-leg length, jacket and branch labeling can be configured according to the actual cabling architecture and rack layout.

24F MPO-24 to 12× LC Duplex Structure & Mapping
One MPO-24 connector carries twenty-four fibers through a single high-density interface. The breakout section distributes those fibers into twelve LC duplex branches, with two fibers allocated to each duplex optical path.
This allows a Base-24 MPO connection to terminate directly at LC-based equipment or patching interfaces without an additional MPO-to-LC cassette at the breakout point.
MPO Side: 1× MPO-24 / MTP-24 UPC
Breakout Side: 12× LC Duplex UPC
Total Fiber Count: 24 Fibers
Duplex Channels: 12
Fiber Mapping Must Match the Complete Channel
The twenty-four MPO fiber positions form twelve two-fiber LC duplex channels, but there is no single universal pin-to-LC sequence that should be assumed for every installation.
The required Tx/Rx mapping depends on the selected polarity method, MPO key orientation, gender/pinning, adapters or cassettes in the channel and the equipment interfaces at both ends.
Type B is commonly specified for MPO breakout assemblies, but it should not be selected only because it is common. The final mapping should be confirmed against the end-to-end topology before production.
Recommended RFQ information: MPO gender, required polarity, existing cabling method, LC branch sequence, transceiver or port information and a simple connection topology.
Key Advantages
12 Duplex Links from One MPO-24
Twenty-four fibers are distributed into twelve LC duplex branches through one high-density MPO interface.
Direct MPO-to-LC Connection
Connect a Base-24 MPO distribution point directly to LC duplex endpoints where a fixed harness is more suitable than a cassette.
Controlled Polarity & Mapping
Type B or project-specific mapping can be configured according to the complete optical channel.
Custom Length, Jacket & Labels
Main cable length, fanout-leg length, jacket rating and LC01–LC12 identification can be configured for the rack layout.
Typical Applications
Data Center Distribution
Distribute one 24-fiber MPO connection into twelve LC duplex links near equipment or patching areas.
Network Migration
Retain existing MPO-24 backbone capacity while presenting LC duplex interfaces at the distribution or equipment side.
Rack-Level Cabling
Route individually labeled LC duplex branches from one MPO-24 connection to nearby equipment ports inside the rack or row.

FAQ
Ordering and Configuration Questions
Q: What is an MPO-24 to 12× LC duplex breakout cable?
A: It is a 24-fiber harness with one MPO-24 / MTP-24 connector on one side and twelve LC duplex branches on the other. The assembly converts one high-density multi-fiber interface into twelve duplex optical paths.
Q: How should polarity and fiber mapping be specified?
A: The mapping should be selected according to the complete optical channel, including MPO key orientation, gender/pinning, adapters or cassettes and the Tx/Rx arrangement of the connected equipment. Type B is common, but the final mapping should be confirmed before production.
Q: Can cable length and LC fanout-leg length be customized?
A: Yes. Main cable length, fanout-leg length, LC01–LC12 identification, jacket and packaging can be configured according to the rack-routing and project requirements.
Q: When should I use a breakout harness instead of an MPO cassette?
A: A direct MPO-to-LC harness is useful for fixed equipment-side fanout and relatively short rack-level connections. For longer permanent backbone runs or networks that require frequent moves, adds and changes, an MPO trunk with modular cassette distribution may provide easier long-term management.
