Cabo de fibra ótica BlueOptics SFP2222BU20MK SC G.657.A1 20 m azul

The BlueOptics SFP2222BU20MK is a 20 metre single-mode fibre optic patch cord with SC/UPC connectors on both ends. It uses G.657.A1 (E9/125 µm) fibre designed for low-loss transmission at 1310 nm and 1550 nm wavelengths. The cable is jacketed with a flame-retardant LSZH material and features a zirconia ceramic ferrule for stable connector performance. Each unit is tested with interferometer and OTDR and shipped with a measurement protocol documenting insertion loss and return loss.

Advantages

This patch cord provides low input loss (under 0.2 dB per mated connector typical) and excellent attenuation characteristics suitable for long-distance single-mode links. The G.657.A1 fibre specification improves bend performance compared with older SMF types, allowing greater installation flexibility in constrained routing paths. Quality-brand components and zirconia ferrules increase durability and support up to typical industry mating cycles, while LSZH jacketing reduces smoke and toxic gas emission in the event of fire.

Key specifications

How to use

Check connector endfaces for contamination and clean with appropriate fibre cleaning tools before mating. Insert the SC connectors into the corresponding SC ports on patch panels or transceivers until a positive click is felt. Avoid tight bends and secure the cable along its route using suitable cable management to maintain the recommended bend radius for G.657.A1 fibre. When disconnecting, pull by the connector body and not by the cable jacket to prevent stress on the termination.

Recommendations

Store the cable coiled with a natural loop to avoid kinks. For optimal long-term performance, keep end caps fitted when connectors are not in use and perform periodic visual inspection and loss measurement if part of a critical link. Use LSZH cabling where low smoke and halogen-free behaviour is required by building regulations.
