## Summary description

The BlueOptics SFP3131BU15MK is a 15 m InfiniBand fibre optic cable with LC connectors. It features OS2 fibre type and a core diameter of 9 µm, ensuring high-speed data transmission and minimal signal loss. Ideal for data centers and high-performance computing environments.

## Long description

The BlueOptics SFP3131BU15MK InfiniBand fibre optic cable 15 m LC is a single‑mode duplex LC‑to‑LC patch cord designed for high‑speed data transmission in data centres and high‑performance computing environments. The cable uses G.657.A1 (E9/125 µm) laser‑optimized single‑mode fibre with a 9 µm core diameter and a yellow LSZH jacket, and is specified for transmission at 1310 nm and 1550 nm. Connectors use zirconia ceramic ferrules and the assembly is tested with interferometer and OTDR to provide documented insertion loss and return loss values.
Advantages
The cable offers low attenuation (approximately 0.4 dB/km) and low insertion loss for reliable long‑distance single‑mode links. Its LSZH (low smoke zero halogen) jacket reduces smoke and halogen emissions in case of fire, making it suitable for use in enclosed facilities. Precision polished LC connectors with quality ferrules ensure high return‑loss performance and up to 1500 mating cycles. Each unit is delivered with a measurement protocol for insertion loss and return loss.
Suitable for
Interconnections between InfiniBand or optical transceiver ports in data centres
High‑performance computing clusters and server racks
Patch panel to transceiver or patch panel to patch panel connections
Environments requiring low smoke and halogen‑free cabling (LSZH)
Key specifications

How to use
Route the BlueOptics LC‑LC cable between the two LC ports to be connected, avoiding sharp bends and securing the cable to cable management to prevent strain on the connectors. Before insertion, verify connector cleanliness and, if necessary, clean connector endfaces with appropriate fibre cleaning tools to prevent increased insertion loss. Insert the duplex LC connectors into the corresponding duplex adapter or transceiver slot until they latch; reverse the process to disconnect. Store the cable coiled without tight loops when not in use.
Usage recommendations
Use this single‑mode 15 m LC‑LC patch cord for short‑ to medium‑range single‑mode links inside racks and across patch panels. Maintain minimum bend radius as specified by the manufacturer, keep connectors capped when idle, and use the included test report to verify link performance during installation and troubleshooting.
