## Summary description

The BlueOptics SFP2121BU7.5MK is a 7.5 m fibre optic cable designed for high-speed data transmission. It features LC connectors and a core diameter of 125 µm, ensuring reliable performance and compatibility with various devices. The G.657.A1 fibre type provides flexibility and durability, making it suitable for various networking applications.

## Long description

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.
Suitable for
Connecting patch panels to optical transceivers in single-mode networks
Short campus or data centre links requiring 7.5 m patch cords
High-speed telecom and ISP aggregation where 1310/1550 nm wavelengths are used
Environments requiring low-smoke, halogen-free cabling (LSZH)
Key specifications
Length: 7.5 m
Connector type: LC/PC to LC/PC (simplex)
Fibre type: Single-mode G.657.A1 (E9/125 µm)
Jacket: LSZH (low smoke zero halogen)
Wavelength compatibility: 1310 nm and 1550 nm
Typical attenuation: 0.4 dB/km
Ferrule material: Zirconia ceramic
Polish options: UPC or 8° APC (return loss optimisation)
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.
Usage 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.
