## Summary description

The BlueOptics SFP3131BU50MK is a 50 m InfiniBand fibre optic cable featuring LC connectors. It utilizes G.657.A1 fibre type with a core diameter of 9 µm, ensuring full duplex communication. Ideal for high-speed data transmission in data centers and networking applications.

## Long description

The BlueOptics SFP3131BU50MK InfiniBand fibre optic cable is a 50 m duplex LC-LC single-mode patch cord using G.657.A1 (9 µm core) fibre. Designed for full duplex communication, it supports transmission at 1310 nm and 1550 nm and is suitable for connecting optical transceivers, patch panels or other fibre endpoints in data centre and networking environments. The cable is delivered in yellow with LC/UPC connectors on both ends and a flame-retardant LSZH outer jacket for reduced smoke and no halogen release.
Advantages
This 50 m BlueOptics patch cord provides low attenuation (specified at approximately 0.4 dB/km) and low insertion loss with high return loss performance; connector polish options such as UPC or APC allow further optimisation of return loss where required. High-quality branded single-mode fibre and precision zirconia ferrules are used to ensure consistent, low-loss connections and a rated mating cycle lifetime up to 1500 matings. Each cable is tested with interferometer and OTDR and shipped with a measurement report for input loss and return loss to verify performance.
Suitable for
Connecting InfiniBand or optical transceivers in high-speed networking links
Patch panel to transceiver or transceiver-to-transceiver connections in data centres
Longer in-rack or inter-rack single-mode connections where 50 m length is required

Jacket material: LSZH (low smoke, zero halogen), yellow
Typical attenuation: ~0.4 dB/km
Mating durability: up to 1500 mating cycles
Tested with interferometer and OTDR; measurement report included
How to use
Route the BlueOptics SFP3131BU50MK cable between the required ports, avoiding tight bends and excessive tension. Align and insert the LC connectors into compatible LC ports on patch panels or transceivers until they click into place, ensuring the polished endfaces are clean and undamaged before mating. For best performance, keep connector endfaces capped when not in use and follow standard fibre handling procedures to prevent contamination or mechanical damage.
Usage recommendations
Clean connector endfaces with appropriate fibre cleaning tools before connection, use bend-radius-compliant routing and avoid exposure to chemicals or sharp edges. Choose UPC or APC polish according to return-loss requirements. Store and handle the LSZH cable to preserve its mechanical integrity and to maintain certified test results.
