Product information

Description

Extralink InfiniBand/fibre optic cable EX.3678 is a single-mode patchcord designed for FTTH installations and short-distance optical links. The 5 m cable uses G.657.A1 fibre that provides improved bend performance compared with standard single-mode fibres. Terminated with an SC connector on one end and an LC connector on the other, the cable supports full-duplex transmission and is suitable for connecting optical equipment such as switches, media converters, OLTs and ONUs/ONTs.

Advantages

The cable combines a compact 3.0 mm jacket with G.657.A1 single-mode fibre to deliver reliable signal integrity and enhanced bending tolerance in confined routing environments. SC to LC termination enables easy integration between devices with different connector types, while the full-duplex pairing ensures simultaneous transmit and receive channels. The yellow jacket provides standard colour coding for single-mode links, simplifying identification in multi‑cable installations.

Suitable for

FTTH drop and in-premises connections between OLT and ONU/ONT
Patching between optical switches, routers and media converters
Short-distance backbone or equipment interconnects in data centres and telecom racks
InfiniBand or other single-mode optical links requiring SC-to-LC connections

Key specifications

Fibre type: single-mode G.657.A1
Length: 5 m
Connector types: SC (one end) to LC (other end)
Transmission: full-duplex (separate Tx/Rx channels)
Jacket colour: yellow (single-mode standard)
Cable diameter: 3.0 mm

How to use

Inspect connector endfaces before installation and clean if necessary to avoid contamination-related signal loss. Route the cable without sharp bends; although G.657.A1 fibre tolerates tighter radii than standard single-mode fibre, maintain smooth curves and avoid kinks. Plug the SC connector into the SC adapter or equipment port and the LC connector into the corresponding LC port, ensuring correct orientation and secure mating. Verify link status and optical power levels with appropriate test equipment after connection.

Usage recommendations

For best long-term performance, avoid repeated flexing near connector ends and secure the cable to prevent strain. Use dust caps when connectors are not mated and follow equipment manufacturer guidelines for port handling and optical power budgets.
