Fibre optic cable BlueOptics SFP2121BU5MK 5 m LC OS2 9 µm

The BlueOptics SFP2121BU5MK 5 m LC OS2 9 µm is a single-mode fibre optic patch cable designed for high-speed data transmission between network devices. It features LC simplex connectors on both ends and OS2 / G.657.A1 single-mode fibre with a 9 µm core diameter. The cable is supplied in a 5 metre length with a yellow LSZH jacket and is intended for connecting patch panels, optical transceivers and other fibre ports that require LC-LC single-mode links.

Advantages

This 5 m LC-LC single-mode cable provides low attenuation and high return loss characteristics suitable for 1310 nm and 1550 nm signal transmission. The LSZH jacket reduces smoke and avoids halogen release in case of fire, meeting common industry safety standards. Connectors use zirconia ceramic ferrules and are manufactured to provide reliable mating cycles; factory testing with interferometer and OTDR is performed and measurement protocols for insertion loss and return loss are included with each cable.

Suitable for

• Connecting optical transceivers in switches, routers and servers
• Patch panel to patch panel or patch panel to transceiver links
• Single-mode LAN, data centre and telecom backbone connections
• Short horizontal or vertical interconnects inside racks or cabinets

• Jacket: LSZH (low smoke, zero halogen), yellow
• Designed wavelengths: 1310 nm and 1550 nm
• Typical attenuation value: approximately 0.4 dB/km (manufacturer specification)
• Tested with interferometer and OTDR; measurement protocol supplied

How to use

Unpack the BlueOptics 5 m LC-LC single-mode cable and remove protective caps from the LC connectors before insertion. Align the LC connector latch with the device port and push gently until it clicks to ensure a secure connection. Avoid tight bends and kinks in the fibre; maintain a minimum bend radius as recommended for single-mode fibre to prevent increased attenuation. When disconnecting, depress the latch and pull the connector straight out to avoid damaging the ferrule.

Usage recommendations

For optimal performance, route the cable away from mechanical stress and electromagnetic interference sources, keep connector endfaces clean using appropriate fibre cleaning tools, and store spare cables with dust caps fitted. Use the supplied test protocol to verify insertion loss and return loss after installation. If a different polish type (UPC or APC) is required for system compatibility, select the suitable variant at time of ordering.
