## Summary description

The BlueOptics SFP3131BU5MM is a 5 m InfiniBand fibre optic cable featuring LC connectors and a core diameter of 9 µm. It supports full duplex communication, making it ideal for high-speed data transmission in data centers and networking applications.

## Long description

BlueOptics SFP3131BU5MM is a 5 m single-mode duplex fiber optic patch cord with LC/APC to LC/APC (8° angled polish) connectors and laser-optimized single-mode fiber (E9/125 µm, G.657.A1). The cable is yellow, features a flame-retardant LSZH jacket and is suitable for connecting patch panels, optical transceivers and other InfiniBand or fiber network equipment for transmission at 1310 nm and 1550 nm.
Advantages
The cable provides low attenuation (0.4 dB/km), low insertion loss and high return loss. It is manufactured with branded single-mode fiber from reputable producers and fitted with precision ceramic ferrule connectors that support up to 1500 mating cycles. Each unit is factory-tested with interferometer and OTDR and shipped with a measurement protocol for insertion loss and return loss. The product also conforms to Telcordia GR-326-Core and common industrial standards and uses an LSZH jacket to reduce smoke and avoid halogens in case of fire.
Suitable for
 High-speed InfiniBand and fiber channel connections in data centers
 Interconnection of optical transceivers and patch panels
 Longer-reach single-mode links at 1310 nm and 1550 nm

How to use
Inspect connectors and ports for dust or damage before installation. Align each LC/APC connector with the corresponding LC/APC port and insert until it clicks gently. Use the duplex clip or retainers on patch panels to secure the cable and avoid tight bends; follow the manufacturer's minimum bend radius for single-mode G.657.A1 fiber. For optimal performance, keep connector endfaces clean and store unused connectors with protective caps.
Usage recommendations
For reliable long-term performance, perform end-to-end testing after installation (OTDR or insertion loss measurement) and replace or re-clean connectors that show elevated loss or contamination. Choose the LSZH jacket when working in confined spaces or installations where low smoke and halogen-free behavior is required.
