BlueOptics SFP2121BU50MK InfiniBand fibre optic cable 50 m LC Yellow

The BlueOptics SFP2121BU50MK InfiniBand fibre optic cable is a 50 m LC–LC simplex patch cord designed for single-mode transmission using G.657.A1 fiber. Finished in yellow with LC/PC connectors on both ends and a flame-retardant LSZH jacket, this cable supports 1310 nm and 1550 nm wavelengths and is intended for reliable interconnection of optical transceivers, patch panels and active networking equipment in data centers and telecom enclosures.

Advantages

This cable uses G.657.A1 single-mode fiber optimized for low bend loss and stable signal transmission over the specified distance. The LSZH outer jacket reduces smoke and avoids halogen emissions in case of fire, meeting common safety requirements for indoor installations. Connectors employ high-quality zirconia ceramic ferrules and branded components that provide consistent insertion/return loss performance; each cable is factory-tested with interferometer and OTDR and shipped with a measurement protocol documenting input and return loss.

Suitable for

• Interconnecting optical transceivers in switches, servers and storage devices
• Patch panel to patch panel connections in data centers and server rooms
• InfiniBand and high-speed networking links requiring single-mode LC terminations
• Cable runs where reduced bend sensitivity is required (tight routing or cabinet transitions)

• Durability: zirconia ceramic ferrule, up to ~1500 mating cycles (manufacturer specification)
• Testing: interferometer and OTDR test with measurement report included

How to use

Route the BlueOptics LC–LC patch cord between the two LC ports to be connected, taking care to maintain minimum bend radii and avoid sharp kinks. Remove protective dust caps from the LC connectors before insertion and, if present, clean connector endfaces with appropriate fiber cleaning tools to ensure low insertion loss. Insert the LC connectors into the transceiver or patch panel ports until they latch; repeat on the opposite end. After installation, verify link status and review the included measurement report to confirm insertion and return loss are within acceptable limits.

Usage recommendations

Store and handle the cable coil without twisting and maintain recommended bend radius for G.657.A1 fiber. Use dust caps whenever connectors are not engaged, perform end-face cleaning before mating, and follow equipment manufacturer guidelines for optical power levels to avoid receiver damage.
