## Summary description

The BlueOptics SFP2121BU30MM is a 30 m InfiniBand fibre optic cable featuring LC connectors and G.657.A1 fibre type. It is designed for high-speed data transfer with a core diameter of 125 µm, ensuring reliable connectivity for data centers and networking applications.

## Long description

The BlueOptics SFP2121BU30MM InfiniBand fibre optic cable 30 m LC Yellow is a single-mode patch cable designed for high-speed networking environments. It uses G.657.A1 fiber with a 125 µm core diameter and LC connectors on both ends, offering reliable optical transmission over a 30-meter distance. The cable's yellow jacket and LC terminations make it suitable for organized rack and data center deployments where clear identification and compact connectors are required.
Advantages
This InfiniBand fibre cable provides low attenuation and good bend performance thanks to the G.657.A1 fiber specification, improving signal integrity in dense cabling areas. The LC connector format delivers a compact connection profile that saves port space in switches and transceivers. A 30 m length covers typical intra-rack and short inter-rack runs without additional splicing or intermediate patching.
Suitable for
High-speed InfiniBand interconnects in data centers
Patching between switches, servers, and storage appliances
Short-distance backbone and horizontal cabling
Environments requiring color-coded fiber identification
Key specifications
Fiber type: G.657.A1 single-mode fiber
Core/cladding diameter: 125 µm
Connector type: LC to LC duplex
Cable length: 30 m
Jacket color: yellow
Application: InfiniBand and high-speed optical links
How to use
Install the cable by inserting the LC connectors into compatible transceiver ports or LC adapters, ensuring proper key alignment and secure latch engagement. Route the cable to avoid tight bends below the fiber's minimum bend radius and secure it with appropriate cable management accessories to prevent strain on the connectors. Verify link status on connected equipment and, if necessary, perform optical power or continuity checks to confirm signal integrity.
Usage recommendations
Keep the cable within its specified minimum bend radius, avoid excessive pulling force, and store with protective caps on unused connectors to maintain performance. Use color-coded routing and labeling in racks to simplify maintenance and reduce the risk of accidental disconnection.
