## Summary description

The BlueOptics QK737A is a 50 m InfiniBand fibre optic cable featuring LC connectors and OM4 fibre type. With a core diameter of 125 µm, it ensures high-speed data transmission and reliability for data centers and networking applications.

## Long description

The BlueOptics QK737A InfiniBand fibre optic cable 50 m LC OM4 is a single multimode OM4 fibre assembly with LC connectors designed for high-speed data transmission in networking and data centre environments. The cable has a 50-metre length and a 125 µm core diameter, offering low attenuation and stable signal integrity for short- to medium-range links. It is intended for use where InfiniBand connectivity and multimode OM4 performance are required.
Advantages
This InfiniBand fibre optic cable combines OM4 multimode performance with LC connectors to provide enhanced bandwidth and reduced modal dispersion compared with lower-grade multimode fibres. The 50 m length supports flexible installation in racks and between cabinets while maintaining consistent signal quality. The 125 µm core diameter and fibre construction deliver predictable attenuation and reliable connectivity for densely packed networking equipment.
Suitable for
InfiniBand links in data centres and high-performance computing (HPC) clusters
Inter-rack and intra-rack connections where 50 m multimode cabling is required
Switch-to-switch and switch-to-server multimode fibre connections
Short- to medium-range high-bandwidth optical links
Key specifications
Fibre type: OM4 multimode
Connector type: LC to LC
Length: 50 metres
Core/cladding diameter: 125 µm core (multimode standard cladding)
Application: InfiniBand and multimode optical networks
Typical use range: short- to medium-distance high-bandwidth links
How to use
Confirm compatibility of the LC connector interfaces and the supporting InfiniBand equipment before installation. Route the 50 m cable through cable management systems or trays, avoiding tight bends and excessive pulling force. Terminate each end into the appropriate LC ports on the transceivers, switches or adapters, ensuring secure seating of the connectors. After installation, verify optical link status and perform signal testing to check attenuation and link quality.
Usage recommendations
Handle the cable by the connector boots and maintain minimum bend radius to prevent microbending losses. Clean LC connector end-faces before mating and avoid exposure to dust and moisture. For best performance in InfiniBand or high-bandwidth environments, pair OM4 multimode cable with compatible OM4-rated transceivers and follow your data centre's cabling standards.
