InfiniBand/fibre optic cable BlueOptics 00YL658-BO 7 m QSFP Male/Male

The BlueOptics 00YL658-BO is a 7 m InfiniBand/fibre optic active optical cable (AOC) with QSFP male-to-male connectors designed for high-speed short-reach links. It supports 40GBASE-SR4 multi-mode optical transmission and integrates optical transmitters and receivers in the QSFP modules at each end. The pre-assembled AOC eliminates the need for separate transceivers and patching while providing immunity to electromagnetic interference and consistent optical performance across a 7 metre channel.

Advantages

This 7 m QSFP-to-QSFP AOC offers native support for 40 Gbit/s multi-mode applications and is manufactured to MSA-compatible specifications for straightforward integration with hardware that supports equivalent 40G AOCs. The cable combines integrated transceivers and multi-mode fiber to deliver low latency and high bandwidth with no external patching or additional SFP/QSFP modules. Built from high-quality optical and electronic components, the cable provides stable optical power levels and digital diagnostic monitoring for remote status checks.

Suitable for

• 40G Ethernet short-reach links inside data centres
• High-speed InfiniBand or Fibre Channel over Ethernet connections
• Connecting QSFP ports on switches, routers and storage systems
• Server-to-switch or switch-to-switch aggregation within racks or between adjacent racks

Key specifications

• Length: 7 metres
• Connector type: QSFP male to QSFP male
• Standard: 40GBASE-SR4 compatible multi-mode operation
• Transmission medium: multi-mode fibre with integrated optical transceivers
• Maximum data rate: up to 40 Gbit/s aggregate
• Digital Diagnostics Monitoring (DDM/DOM) support for voltage, temperature, transmit and receive power and laser bias
• Designed for short-range multimode links inside data centre environments

How to use

Install the BlueOptics 00YL658-BO by inserting each QSFP male connector into corresponding QSFP ports on compatible network equipment until the module latches. Ensure ports are powered and configured to accept AOCs; the cable is plug-and-play on hardware that supports QSFP AOCs and 40GBASE-SR4 operation. Use the device management interface to verify link status and, if available, check DDM/DOM values to confirm proper optical levels and temperature during initial deployment.

Recommendations

Route the cable to avoid tight bends; respect the manufacturer’s minimum bend radius for multimode fibre. Verify that the host hardware officially supports QSFP AOCs with 40GBASE-SR4 signalling to ensure full compatibility. Use DDM/DOM readings for preventive maintenance and troubleshooting, and keep connectors clean and protected when not inserted.
