Cavo in fibra ottica BlueOptics SFP3333BU1MK 1 m ST G.657.A1

The BlueOptics SFP3333BU1MK is a 1 m duplex fibre optic patch cord with ST/PC to ST/PC connectors and single-mode G.657.A1 (E9/125 µm) fibre. Designed for reliable high-speed data transmission, this yellow cable supports 1310 nm and 1550 nm wavelength ranges and is intended for short interconnects between patch panels, optical transceivers or network devices. The cable features a flame-retardant LSZH jacket for reduced smoke and no halogen release in case of fire.

Advantages

The cable uses laser-optimized single-mode fibre with low attenuation (~0.4 dB/km) and high return loss, and connectors fitted with zirconia ceramic ferrules for durable mating performance. Components are sourced from established fibre and connector manufacturers to support stable, low-loss links. Each unit is tested with interferometer and OTDR and shipped with measurement data for input loss and return loss.

How to use

Route the 1 m patch cord between the intended ST-terminated ports on patch panels or devices, ensuring connectors are clean and dust-free before mating. Align and insert each ST connector until the bayonet coupling engages; tighten only as required for secure connection. Avoid sharp bends and maintain the recommended minimum bend radius for G.657.A1 fibre to prevent increased attenuation. Store and handle the cable without excessive tensile force to preserve connector alignment and fibre integrity.

Recommendations

Inspect and clean connector endfaces with appropriate fibre cleaning tools before each insertion to maintain low insertion loss and high return loss. Use strain relief and proper routing in racks and enclosures to avoid microbends. For custom lengths or alternate connector polishing (UPC or APC), consult the supplier options.
