Cavo in fibra ottica BlueOptics SFP2121BU7.5MK 7,5 m LC giallo

The BlueOptics SFP2121BU7.5MK is a 7.5 m single-mode fibre optic patch cord with LC/PC to LC/PC simplex connectors and a yellow LSZH jacket. It uses G.657.A1 fibre with a core diameter of 125 µm (E9/125 µm) engineered for low attenuation and compatibility with standard 1310 nm and 1550 nm wavelength systems. The cable is intended for patch panel ports and optical transceiver interconnections where a flexible, durable single-mode link is required.

Advantages

The cable combines a G.657.A1 bend-insensitive fibre with a flame-retardant LSZH outer jacket to reduce smoke and eliminate halogen release in case of fire. Connectors are fitted with zirconia ceramic ferrules for consistent mating performance and long life up to the typical mating cycle specification. Attenuation is low (specified around 0.4 dB/km) and return loss is high; polish options (UPC or 8° APC) allow further optimisation of optical return loss when required. Each unit is factory-tested with interferometer and OTDR and shipped with a measurement protocol for input loss and return loss.

Key specifications

How to use

Route the BlueOptics LC‑LC patch cord between the required patch panel port and the optical transceiver, ensuring connectors are free of dust before insertion. When installing, avoid tight bends and maintain the manufacturer’s minimum bend radius to preserve the G.657.A1 bend-insensitive properties. Insert LC connectors until they click into place, verify link status on connected equipment and, if needed, compare measured insertion loss with the supplied measurement protocol.

Recommendations

Clean connector endfaces with appropriate fibre cleaning tools prior to every connection, store unused connectors with protective caps, and avoid routing the cable near sources of mechanical abrasion or excessive heat. For critical links, verify insertion loss and return loss with optical test equipment and select UPC or APC polish according to system return-loss requirements.
