## Summary description

The BlueOptics SFP2121BU3MM is a 3 m long InfiniBand fibre optic cable featuring LC connectors. It utilizes G.657.A1 fibre optic type for optimal performance in data transmission. Ideal for high-speed networking applications.

## Long description

BlueOptics SFP2121BU3MM is a 3 meter single-mode LC/APC to LC/APC simplex fibre optic patch cord in yellow, using ITU-T G.657.A1 (9/125 µm) fibre. It is designed for reliable transmission of 1310 nm and 1550 nm signals and for connecting patch panel ports, optical transceivers or other LC/APC interfaces in InfiniBand and high-speed networking environments. The cable has a flame-retardant LSZH outer jacket for reduced smoke and no halogen release.
Advantages
The SFP2121BU3MM offers low attenuation (0.4 dB/km), low insertion loss and high return loss. Connectors use a zirconia ceramic ferrule and branded fibre from established manufacturers to ensure consistent, loss-minimised performance and a rated mating durability of up to 1500 cycles. Each cable is tested with interferometer and OTDR and ships with a measurement protocol showing input loss and return loss values.
Suitable for
 Connecting optical transceivers (LC/APC) in InfiniBand and Fibre Channel systems
 Patch panel to transceiver or patch panel-to-panel interconnects
 Long-reach single-mode links at 1310 nm and 1550 nm

How to use
Inspect connector endfaces for cleanliness before insertion. Align the LC/APC connectors and insert gently into the corresponding LC/APC ports on transceivers or patch panels until they click. Avoid tight bends by following the manufacturer’s minimum bend radius and route the cable securely to prevent strain on connectors. For removal, depress the LC latch and pull straight out without twisting.
Usage recommendations
Store and handle the fibre patch cord in a clean environment; clean connector endfaces with appropriate fibre cleaning tools if signal loss increases. If a different cable length is required, custom lengths are available on request.
