BlueOptics CBL-MPO12-4LC-OM4-5M-BO InfiniBand fibre optic cable 4x LC MPO 5m

The BlueOptics CBL-MPO12-4LC-OM4-5M-BO InfiniBand fibre optic cable is a 5 m multi-mode OM4 patch cable with a single MPO (12-fiber) connector to four LC duplex connectors, designed for high-density, high-speed optical links. The cable uses laser-optimized 50 µm OM4 fibre to support full-duplex communication and low attenuation across short- to medium-range data centre and enterprise connections. Its LSZH (low smoke zero halogen) sheath reduces smoke and toxic emissions in case of fire, and the assembled connectors incorporate zirconia ceramic ferrules to maintain stable optical performance and long mating life.

Advantages

This InfiniBand fibre cable provides low insertion loss and high return loss suitable for demanding optical networks. Manufactured with branded multi-mode fibres and proven connector components, the cable is factory-tested using interferometry and OTDR and is supplied with measured input loss and return loss values. The compact MPO-to-4x LC duplex configuration enables efficient port consolidation on patch panels and transceivers while the OM4 fibre specification improves modal bandwidth and supports higher data rates over multi-mode links.

Suitable for

• Data centre uplinks and cross-connects between MPO trunk and LC patch panels
• InfiniBand and high-speed Ethernet short- to medium-reach links
• Connecting MPO-enabled transceivers to multiple LC duplex ports
• High-density rack installations where space and cable management are critical

Key specifications

• Length: 5 m
• Fibre type: OM4 multi-mode, 50 µm core
• Connector A: MPO (multi-fibre push-on), UPC-polished
• Connector B: 4 × LC duplex, UPC-polished
• Jacket: LSZH (low smoke zero halogen), flame-retardant
• Polishing: UPC (ultra physical contact) for reduced back reflection
• Tested: interferometer and OTDR with printed input and return loss measurements
• Compliance: manufactured to common industrial safety and material standards (IEC, RoHS)

How to use

Route the cable through the planned cable management path and avoid sharp bends that exceed the manufacturer’s minimum bend radius. Align and insert the MPO connector into the MPO trunk or transceiver receptacle until it latches, and plug each LC duplex connector into the corresponding LC port on the patch panel or transceiver, observing correct polarity for full-duplex operation. Ensure connectors are clean before mating to prevent contamination-related signal loss; use appropriate fibre cleaning tools or wipes. After installation, verify link performance using an optical power meter or appropriate test equipment and compare measured insertion and return loss to the supplied measurement protocol.

Usage recommendations

Store and handle the cable in a clean environment, keep protective caps on connectors when not in use, and avoid compressive forces or kinking. For permanent installations in public or confined spaces, the LSZH jacket reduces harmful emissions. For long-term reliability, schedule periodic visual inspections and cleaning of connector endfaces and retest links after any significant reconfiguration.
