Fibre optic cable EFB Elektronik MTPF12LCOM3-15 — 15 m OM3 MTP to 12×LC, 50 µm (purple)

EFB Elektronik MTPF12LCOM3-15 is a 15 m multimode fibre optic cable designed for short-range, high-density network interconnects. One end terminates in an MTP connector that aggregates 12 fibres; the other end breaks out into 12 LC connectors. The cable uses 50 µm OM3 multimode fibre, optimized for 10GbE and 40GbE links and commonly used in data centre rack-to-rack, patch panel and switch interconnect scenarios. The purple jacket denotes OM3 grade and helps with fast visual identification and structured cabling management.

Advantages

The cable offers a compact MTP-to-LC breakout that reduces port footprint while supporting parallel optics applications. OM3 50 µm multimode construction provides low insertion loss and controlled modal bandwidth suitable for short-reach high-speed links. The factory-terminated connectors ensure consistent performance and simplify deployment compared with field-terminated assemblies. The 15 m length provides flexibility for typical rack spacing without excess slack.

Suitable for

• Data centre rack-to-rack and switch-to-switch connections
• Patch panels and high-density fibre enclosures
• Parallel optics and MPO/MTP-based transceiver systems (eg. 40G/100G implementations)
• Short-range multimode links such as InfiniBand or Fibre Channel within equipment rooms

Key specifications

• Fibre type: OM3 multimode, 50 µm core
• Connector configuration: MTP (one end) to 12 × LC (other end)
• Length: 15 metres
• Jacket colour: purple (OM3 identification)
• Typical use: short-range, high-density parallel optic links
• Termination: factory-polished connectors for consistent optical performance

How to use

Route the cable through cable trays or underfloor pathways to avoid sharp bends and excessive tensile stress. Insert the MTP connector into the corresponding MTP/MPO port on the transceiver or patch panel, ensuring proper key orientation and alignment. Connect the 12 LC connectors into the LC ports of switches, patch panels or breakout modules, observing transmitter-to-receiver pair mapping as required by the equipment. Secure connectors and manage excess length with cable ties or cable management panels to maintain minimum bend radius and prevent microbending losses.

Usage recommendations

Inspect connector endfaces before installation and clean with approved fibre cleaning tools to prevent contamination-related loss. Avoid tight bends and compressions; follow vendor-specified minimum bend radius. Use labelled routing and patch panel documentation to keep track of the MTP-to-LC mapping and to simplify future maintenance or reconfiguration.
