BlueOptics SFP3133BU3MK cavo in fibra ottica InfiniBand 3m LC ST giallo

BlueOptics SFP3133BU3MK is a 3 meter duplex fibre optic patch cord with LC/UPC to ST/PC connectors and yellow LSZH jacket. The cable uses single-mode G.657.A1 fiber (9/125 µm) optimized for 1310 nm and 1550 nm transmission and is intended for full-duplex connections between patch panels, optical transceivers and other network devices.

Advantages

The cable offers low attenuation (specified at 0.4 dB/km), low insertion loss and high return loss; connector polish options (UPC or 8° APC) allow further return-loss optimization. Components include branded fibers from manufacturers such as Corning, Fujikura or YOFC and precision connectors with zirconia ceramic ferrules rated up to 1500 mating cycles. Each cable is tested with interferometer and OTDR and supplied with a measured insertion-loss and return-loss protocol.

How to use

Inspect connectors and cable for visible damage before installation. Clean connector endfaces according to standard fiber-cleaning procedures, then plug the LC duplex connector into the transceiver or patch-panel port and the ST connector into the corresponding port. Ensure correct duplex orientation for transmit/receive pairing and secure the cable to avoid sharp bends (observe the manufacturer’s minimum bend radius). After installation, verify link performance using appropriate optical test equipment.

Recommendations

Use in indoor environments where low smoke and halogen-free behavior is required; avoid tight bends and mechanical strain, keep endfaces clean, and consider UPC or APC polish choices based on return-loss requirements for your devices.
