InfiniBand/fibre optic cable BlueOptics SFP3131BU30MK 30 m LC Yellow

The BlueOptics SFP3131BU30MK is a 30 m InfiniBand / fibre optic cable with duplex LC connectors and a yellow LSZH jacket. It uses laser-optimized single-mode G.657.A1 fibre (9 µm core) designed for full duplex transmission at common wavelengths such as 1310 nm and 1550 nm. The cable is suitable for connecting patch panels, transceivers and other optical ports where single-mode LC-LC connections are required. Each cord is factory-tested for insertion loss and return loss with measurement data provided.

Advantages

This 30 m LC–LC single-mode patch cord combines low attenuation and high return loss to support error-free long-distance and high-speed links. The LSZH jacket reduces smoke and avoids halogen emissions in case of fire, meeting relevant industry norms. Connectors use zirconia ceramic ferrules and branded fibre to ensure consistent performance and durability through many mating cycles. A measurement protocol for insertion and return loss is included with each cable.

Suitable for

• Connecting optical transceivers (SFP/SFP+/InfiniBand) and patch panels
• Single-mode fiber links in data centers and server rooms
• Backbone and distribution cabling where LC–LC duplex is required
• Installations requiring low-smoke, zero-halogen (LSZH) jackets

How to use

Route the BlueOptics LC–LC patch cord between the required ports, taking care to avoid sharp bends and excessive pulling. Remove protective caps from LC connectors before insertion and align the keyed connector with the device port until it clicks. For duplex links ensure the transmit and receive fibers are connected to the correct TX/RX ports. After installation, verify link quality using appropriate optical test equipment or confirm device-level connectivity.

Usage recommendations

Store and install the cable within manufacturer-recommended bend radius limits; avoid kinking. Use the included test report to validate insertion and return loss values during acceptance testing. For permanent or outdoor runs, select appropriate routing and additional protection; for high-density environments label both ends for easy identification.
