BlueOptics WPN77-BO InfiniBand/fibre optic cable 10 m QSFP

The BlueOptics WPN77-BO InfiniBand/fibre optic cable 10 m QSFP is a 10-meter active optical cable (AOC) with QSFP connectors on both ends. Designed for data center and enterprise networking environments, this cable supports 40GBASE-SR4 multi-mode optical links and is suitable for connecting servers, switches and storage systems over short to medium rack-to-rack distances. The integrated optical transmitter and receiver on each end convert electrical signals to optical signals and are built to comply with industry MSA guidelines for QSFP interconnects.

Advantages

The cable provides 40 Gbit/s aggregate bandwidth per link using QSFP to QSFP termination and reduces electromagnetic interference compared to copper alternatives. As an active optical cable it integrates lasers and receiver electronics to maintain signal integrity over the 10 m length while minimizing insertion loss. The product is manufactured to industry module alignment and component standards to ensure predictable interoperability with hardware that supports 40GBASE-SR4 QSFP AOCs.

Suitable for

• Rack-to-rack links in data centers
• Server-to-switch connections in high-density environments
• Interconnects for storage arrays and SANs
• High-speed InfiniBand or Ethernet fabrics up to 40 Gbit/s

Key specifications

• Cable type: Active Optical Cable (AOC) with QSFP to QSFP connectors
• Length: 10 meters
• Transmission standard: 40GBASE-SR4 compatible, multi-mode fiber
• Data rate: up to 40 Gbit/s aggregate per link
• Connector form factor: QSFP (quad small form-factor pluggable)
• Features: integrated optical transmitter and receiver, Digital Diagnostics Monitoring (DDM) / Digital Optical Monitoring (DOM) support where host hardware provides access

How to use

Install the BlueOptics WPN77-BO by inserting each QSFP connector into the corresponding QSFP port on your network devices while the devices are powered down or following your hardware vendor’s hot-plug guidance. Verify that both endpoints support 40GBASE-SR4 or the intended protocol (Ethernet, Fibre Channel over Ethernet or InfiniBand) and that the device firmware recognizes AOC modules. When available, use the host’s diagnostic interface to read DDM/DOM parameters such as supply voltage, temperature and optical power for link validation.

Usage recommendations

Route the cable without tight bends and avoid mechanical stress near the QSFP housings. Ensure connected equipment supports QSFP AOCs and DDM/DOM if you require diagnostic monitoring. For consistent performance, use the cable in accordance with data center cabling best practices and verify compatibility with your switch or server vendor documentation before deployment.
