## Summary description

The BlueOptics SFP2121BU1MM is a 1m InfiniBand fibre optic cable designed for high-speed data transmission. It features LC connectors and an OS2 fibre type with a core diameter of 9 µm, ensuring reliable performance for networking applications.

## Long description

BlueOptics SFP2121BU1MM is a 1 metre LC–LC simplex fibre optic patch cord in yellow, designed for single-mode (OS2 / G.657.A1, 9/125 µm) transmission. It uses LC/APC connectors on both ends, a flame-retardant LSZH jacket and is intended for connecting patch panel ports, optical transceivers or other fibre equipment to support 1310 nm and 1550 nm signals.
Advantages
The cable offers low attenuation (0.4 dB/km), low insertion loss and high return loss, with the option to further optimise return loss by using APC polish. Components include branded single-mode fibre from recognised manufacturers and BlueOptics zirconia ferrules; connectors are produced by established suppliers and the ferrule design supports up to 1500 mating cycles. Each assembly is tested with interferometer and OTDR and shipped with a measurement protocol of insertion loss and return loss values.
Suitable for
Connecting optical transceivers (InfiniBand, SFP modules) to patch panels
Single-mode network links operating at 1310 nm and 1550 nm
Data centre and telecom fibre interconnects requiring LSZH jackets
Short fixed-length fibre runs where a 1 m LC–LC simplex lead is required

How to use
Verify that both ends are clean and free of dust before connector mating. Insert the LC connectors into the corresponding LC/APC ports of patch panels or transceivers, ensuring the APC key alignment for correct polish orientation. Avoid tight bends and secure the cable to prevent strain on connectors. For best optical performance, follow standard cleaning and handling procedures for single-mode fibre connections.
Usage recommendations
Store and handle the cable in a dry environment; maintain minimum bend radius per manufacturer guidance, use fibre cleaning tools before connection, and request custom lengths if different run distances are required.
