Fibre optic cable BlueOptics SFP2121BU0.5MK 0.5 m LC OS2 9 µm

The BlueOptics SFP2121BU0.5MK 0.5 m LC OS2 9 µm is a single-mode fibre optic patch cord designed for short interconnections in high-speed networks. It uses LC connectors on both ends and a 9 µm core single-mode fibre suitable for OS2 applications. The 0.5 metre length and simplex LC–LC configuration make this cable suitable for connecting optical transceivers, patch panels and other fibre equipment where a reliable, low-loss short link is required. The cable is supplied in BlueOptics’ standard yellow jacket and built to industry safety and performance standards.

Advantages

This fibre patch cord delivers low attenuation and high return-loss performance typical for OS2 single-mode fibres, supporting transmission at common wavelengths such as 1310 nm and 1550 nm. Connectors are manufactured with zirconia ceramic ferrules for stable alignment and long mating life. The cable’s LSZH (low smoke zero halogen) jacket reduces toxic and corrosive emissions in case of fire and meets common regulatory norms. Each unit is tested after production with interferometer and OTDR methods and supplied with a measurement protocol documenting insertion loss and return loss.

Key specifications

How to use

Inspect both LC connector endfaces for dust or contamination and clean with an appropriate fibre cleaning tool if required. Insert the LC connectors into the corresponding transceiver or patch panel ports until a click confirms secure engagement. Route the cable to avoid sharp bends and maintain the manufacturer’s minimum bend radius to prevent increased loss. For removal, depress the connector latch and withdraw straight out to avoid damaging the ferrule or port.

Recommendations

Use the 0.5 m LC–LC OS2 patch cord for short, high-quality connections inside racks and patch panels. Keep connectors capped when not in use and store spares in a dust-free environment. For installations requiring extremely low return loss or long-term outdoor exposure, consider selecting the appropriate polish type and jacket specification to match the installation conditions.
