## Summary description

The BlueOptics SFP3131BU30MK is a 30 m InfiniBand/fibre optic cable featuring LC connectors. It utilizes G.657.A1 fibre optic type with a core diameter of 9 µm, ensuring full duplex communication. Ideal for high-speed data transmission in networking applications.

## Long description

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
Key specifications

Attenuation: approx. 0.4 dB/km (typical)
Jacket: LSZH (low smoke, zero halogen)
Duplex/full duplex support
Tested with interferometer and OTDR; measurement protocol included
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.
