## Summary description

The BlueOptics SFP9131BU5MK is a high-quality 5 m fibre optic cable designed for reliable data transmission. It features a CS connector on one end and an LC connector on the other, ensuring compatibility with various devices. With a core diameter of 9 µm and OS2 fibre type, this cable supports full duplex communication, making it ideal for high-speed networking applications. Its yellow color makes it easy to identify in installations.

## Long description

The BlueOptics SFP9131BU5MK CS LC OS2 5 m Yellow fibre optic cable is a 5-metre single-mode patch cord designed for reliable, low-loss optical connections. It has a CS connector on one end and an LC connector on the other, uses OS2 / G.657.A1 laser-optimized single-mode fibre with a 9 µm core, and comes in a yellow LSZH jacket for easy identification and reduced smoke emission in case of fire. The cable supports full-duplex transmission and is suitable for linking patch panels, optical transceivers and other active equipment in telecom and data centre environments.
Advantages
The CS-to-LC configuration provides compatibility between devices with different connector types while maintaining low insertion loss and high return loss. The use of laser-optimized single-mode fibre (OS2 / G.657.A1) delivers excellent attenuation characteristics suitable for 1310 nm and 1550 nm wavelengths. High-quality zirconia ferrules and branded fibre ensure consistent performance and long-term reliability. The LSZH jacket reduces toxic and corrosive gases in the event of fire and the yellow colour improves cable management and traceability in installations.
Suitable for
 Interconnection between optical transceivers and patch panels with CS and LC ports
 Data centre and server room fibre patching
 Telecommunication links operating at 1310 nm and 1550 nm
 Environments requiring low-smoke, zero-halogen cabling
Key specifications

How to use
Inspect connectors and cable for visible damage before installing. Align and insert the CS connector into the CS port and the LC connector into the LC port until secure; ensure duplex orientation matches the transmit/receive pairing on both ends. Route the cable following existing cable management paths, avoiding tight bends and excessive tension to preserve the fibre bend radius. After installation, verify optical link performance using an appropriate power meter or OTDR and keep the supplied measurement protocol for reference.
Usage recommendations
Store and handle the cable in protective packaging until installation to prevent contamination of ferrules. Maintain bend radii recommended by the manufacturer, avoid sharp bends and secure the cable with non-compressive ties. For links requiring the lowest possible return loss, request APC-polished connectors at the time of order. Use the included test report to validate each link after installation and periodically inspect connectors for cleanliness to ensure error-free transmission.
