## Summary description

The BlueOptics CBL-403-BO is a 3 m InfiniBand/fibre optic cable featuring QSFP connectors on both ends. It is designed for high-speed data transfer in data centers and networking environments, ensuring reliable connectivity and performance.

## Long description

The BlueOptics CBL-403-BO InfiniBand/fibre optic cable 3 m QSFP is a 3-meter duplex fibre link with QSFP connectors on both ends, intended for high-speed interconnects in data centers and professional networking environments. Designed to support low-latency, high-throughput connections, this cable provides a compact and standardized interface for servers, switches and storage systems that use QSFP ports.
Advantages
This 3 m QSFP fibre cable delivers high data-rate capability and stable optical performance suitable for demanding network topologies. Its QSFP-to-QSFP termination reduces the need for additional adapters, while the predetermined length simplifies rack-to-rack or chassis-to-chassis connections. The cable construction ensures consistent signal integrity and minimal insertion loss across the link, contributing to reliable long-term operation in dense installations.
Suitable for
 High-speed server-to-switch links in data centers
 Interconnects between network switches and storage arrays
 InfiniBand fabrics and HPC cluster backbones
 Patch connections within optical distribution frames and racks
Key specifications
 Connector type: QSFP on both ends (quad small form-factor pluggable)
 Length: 3 meters
 Fibre type: multimode optical fibre (compatible with InfiniBand and common QSFP transceivers)
 Performance: engineered for low insertion loss and low latency
 Usage environment: indoor, structured cabling and data center racks
How to use
Install the cable by aligning the QSFP connector keys with the port receptacles and gently inserting until the connector is fully seated. Route the cable within racks or trays to avoid sharp bends and maintain the recommended minimum bend radius for multimode fibre. For patching, use the 3 m length to connect adjacent equipment or neighboring rack units; verify link status on both devices after connection and check optical power levels if required.
Usage recommendations
Handle with care to prevent fibre damage: avoid excessive pulling, kinks and tight bends. Keep connector endfaces clean and protected when not in use; use appropriate cleaning tools before mating to maintain optimal optical performance. For highest reliability, follow data center cable management best practices and verify compatibility of QSFP transceivers and ports before deployment.
