BlueOptics CBL-MPO12-4LC-SMF-1M InfiniBand fibre optic cable MPO 4x LC 1m

The BlueOptics CBL-MPO12-4LC-SMF-1M InfiniBand fibre optic cable is a 1 meter multimode-structured singlemode patch lead designed for high-density network environments. It features an MPO (12-fiber) connector on one end and four LC connectors on the other, enabling parallel optics connections and easy fan-out to LC-based transceivers. The cable uses G.657.A1 singlemode fibre with a 125 µm cladding diameter, offering low attenuation and good bend performance suitable for racks, patch panels and short intra-rack runs.

Advantages

This BlueOptics cable combines a compact MPO interface with multiple LC terminations to simplify connections between parallel transceivers and LC ports without additional conversion modules. The G.657.A1 fibre type provides improved bend tolerance compared with older singlemode variants, reducing signal loss in constrained cable routes. At 1 meter length the assembly minimizes slack in patching scenarios and supports consistent performance for InfiniBand and other high-speed data applications.

Suitable for

• Connecting MPO-based parallel optics transceivers to multiple LC transceivers or ports
• Intra-rack or short inter-rack fibre patching where a 1 m length is required
• High-density server, switch and storage environments using InfiniBand or other high-speed links
• Data centres requiring improved bend performance in tight routing paths

Key specifications

• Connector 1: MPO (12-fiber) multi-fiber connector
• Connector 2: Four LC duplex connectors
• Fibre type: G.657.A1 singlemode fibre
• Core/cladding: 125 µm cladding diameter
• Length: 1 m
• Intended use: InfiniBand and high-speed optical links

How to use

Identify the MPO end and align it with the MPO port on the parallel transceiver or patch panel, ensuring correct key orientation before insertion. Route the cable to the destination LC ports and plug each LC connector into the corresponding transceiver or patch panel adapter. Avoid sharp bends and maintain reasonable bend radii during installation to preserve the G.657.A1 fibre's performance. Perform insertion loss and continuity checks after installation to confirm signal integrity.

Recommendations

For best results, keep the cable length appropriate for the rack layout to reduce excess slack, use dust caps when connectors are not mated, and follow fibre handling practices: avoid twisting, ensure clean connectors, and maintain bend radii consistent with G.657.A1 specifications.
