Fibre optic cable EFB Elektronik O0680.1 — OM3, 1 m, MT-RJ to LC, 50 µm core, turquoise

EFB Elektronik O0680.1 is a 1 m multimode fibre optic cable (OM3) with an MT-RJ connector on one end and an LC connector on the other. The cable uses 50 µm core multimode fibres and is finished in a turquoise sheath. It is designed for short, high-speed multimode optical links such as InfiniBand and data centre interconnects, providing a compact MT-RJ to LC connection for server racks and network equipment.

Advantages

The cable is built with aramid yarn reinforcement for improved tensile resistance and long‑term mechanical stability. The sheath is halogen‑free and flame‑retardant (LSZH) in line with common safety standards. Connectors are manufactured and tested to meet recognised quality grades for multimode fibre, and each unit is 100% checked with an individual test protocol, ensuring consistent optical performance for short-reach multimode applications.

Suitable for

• InfiniBand links and other high-speed multimode connections
• Server rack patching and intra-rack interconnects
• Data centre horizontal and equipment-side short-reach links
• Network equipment connections requiring MT-RJ to LC interface

Key specifications

• Fiber type: Multimode OM3
• Core diameter: 50 µm
• Length: 1 m
• Connectors: MT-RJ (one end) to LC (other end)
• Sheath colour: Turquoise
• Jacket type: Low Smoke Zero Halogen (LSZH)
• Reinforcement: Aramid yarn for tensile strength

How to use

Inspect connector endfaces for contamination and clean with appropriate fibre cleaning tools before insertion. Route the 1 m jumper in the rack or cabinet with gentle bends, avoiding kinked or tightly looped runs to preserve optical performance. Insert the MT-RJ and LC connectors into matching ports until the connectors click or seat fully; ensure correct polarity if used in duplex pairs. Verify link integrity with suitable optical test equipment or by checking the link status on connected devices.

Usage recommendations

Store and handle the cable to avoid excessive bending radius and mechanical strain. Use LC- and MT-RJ-compatible dust caps when connectors are not in use. For installation in fire‑sensitive environments, the LSZH jacket reduces toxic smoke and corrosive gases compared with standard PVC jackets.
