BlueOptics SFP3131BU4MK Καλώδιο οπτικών ινών InfiniBand 4 m LC κίτρινο

The BlueOptics SFP3131BU4MK is a 4 m InfiniBand fibre optic patch cord with duplex LC/UPC to LC/UPC connectors, designed for single-mode transmission using G.657.A1 fiber. With a yellow LSZH outer jacket and laser-optimized single-mode fiber (9/125 µm), this LC–LC cable supports transmission at common wavelengths (1310 nm and 1550 nm) and is intended for short- to medium-reach interconnections in racks, patch panels and optical transceiver links in data centers and networking environments. Each unit is factory-tested for attenuation and return loss and shipped with a measurement protocol.

Advantages

This 4 m LC–LC patch cord offers low attenuation (typical 0.4 dB/km) and high return-loss performance with the option to optimize polish types (UPC or 8° APC) where applicable. The cable uses branded single-mode fiber from established manufacturers and precision zirconia ceramic ferrules for consistent optical mating and durability up to the specified mating cycle. The LSZH jacket reduces smoke and eliminates halogen release in case of fire, meeting industrial safety expectations and Telcordia GR-326-Core requirements.

How to use

Inspect connector endfaces and cable for visible contamination before installation and, if needed, clean using approved fiber-cleaning tools. Route the 4 m patch cord between the two LC ports avoiding sharp bends and excessive tension; maintain the manufacturer recommended minimum bend radius for single-mode fiber. Plug the LC duplex connectors into matching LC ports on patch panels or transceivers, ensuring correct polarity for duplex links. After installation, verify link integrity and loss values using appropriate test equipment; compare measurements with the supplied protocol.

Recommendations

Store and handle the patch cord in a dry, dust-free environment. Use dust caps when connectors are not in use, avoid kinking the cable, and follow standard ESD and fiber-safety procedures when connecting or disconnecting. For applications requiring different polish or specific attenuation targets, request custom polish options or custom lengths from the supplier.
