BlueOptics SFP3133BU1MK InfiniBand fibre optic cable 1 m LC ST Yellow

The BlueOptics SFP3133BU1MK is a 1 m InfiniBand fibre optic patch cable with a duplex LC (UPC) connector on one end and an ST (PC) connector on the other. Constructed from G.657.A1 single-mode fibre with a 9 µm core diameter and a yellow LSZH jacket, this LC–ST cable supports full duplex transmission and is designed for 1310 nm and 1550 nm wavelengths. Connectors use zirconia ceramic ferrules and the assembly is factory-tested with interferometer and OTDR to verify low insertion loss and high return loss for reliable data links.

Advantages

The cable combines single-mode G.657.A1 fibre performance with laser-optimized polish options and low attenuation (typ. 0.4 dB/km), delivering stable long-distance and high-speed signal transmission. Its LSZH jacket reduces smoke and halogen emission in case of fire, meeting common safety standards. High-quality branded fiber and industry-grade connectors ensure durability and up to 1500 mating cycles, while supplied test measurement protocols document insertion loss and return loss values.

Suitable for

• High-speed InfiniBand and fibre channel interconnects requiring duplex LC–ST connections
• Patch panel to transceiver or equipment-to-equipment optical links in data centres
• Single-mode networks operating at 1310 nm or 1550 nm wavelengths
• Environments demanding low-smoke zero-halogen (LSZH) cabling for safety compliance

How to use

Install the BlueOptics SFP3133BU1MK by connecting the duplex LC connector to the corresponding LC port and the ST connector to the ST receptacle on the other device or patch panel. Ensure proper alignment and secure insertion until each connector latches or seats. Avoid bending the cable below the manufacturer’s recommended minimum bend radius and keep connectors clean by using dust caps when not connected. Verify link performance using the supplied insertion loss and return loss measurements or your own test equipment after installation.

Usage recommendations

Store and handle the cable in a clean environment and avoid tight bends or crushing forces. For best optical performance, keep connector end faces clean and, if necessary, perform connector cleaning before mating. Select the appropriate polish type (UPC or APC) according to your system’s return loss requirements and request custom lengths if a different run length is needed.
