BlueOptics JNP-40G-AOC-20M-BO InfiniBand fibre optic cable QSFP 20 m Male/Male

The BlueOptics JNP-40G-AOC-20M-BO InfiniBand fibre optic cable is a 20 m active optical cable (AOC) with QSFP connectors on both ends, designed for 40GBASE-SR4 links. It integrates a transmitter and receiver on each end for multimode fiber optical signal transmission and supports high-speed data protocols such as Ethernet, Fibre Channel over Ethernet and SDH/SONET up to 40 Gbit/s over the 20 m link. The cable follows MSA-compatible QSFP specifications and is intended for integration in systems that support the corresponding original AOC interface.

Advantages

The cable provides low-latency, EMI-immune optical connectivity and eliminates the need for separate transceivers and patching by offering a pre-assembled QSFP-to-QSFP solution. Built and tested to work with major hardware platforms that support the same form factor, it includes digital diagnostics monitoring (DDM/DOM) for real-time reporting of supply voltage, laser bias current, optical transmit/receive power and temperature. The use of quality optical components and compliance with MSA standards contribute to long operational lifetime and stable signal integrity.

Suitable for

• Connecting QSFP ports between switches and routers in data center racks
• Direct links between servers and storage systems requiring 40 Gbit/s bandwidth
• High-performance InfiniBand or Ethernet backplane and top-of-rack connections
• Short-reach multimode fiber links inside equipment rooms and cabling aisles

Key specifications

• Form factor: QSFP-to-QSFP active optical cable
• Nominal data rate: up to 40 Gbit/s aggregate (40GBASE-SR4)
• Length: 20 metres
• Fiber type: multimode (MSA-compliant AOC)
• Integrated features: transmitter and receiver modules on both ends
• Monitoring: Digital Diagnostics Monitoring (DDM/DOM) per MSA SFF-8472
• Connector gender: male QSFP on both ends

How to use

Install the cable by inserting each male QSFP connector into the corresponding QSFP socket on compatible switches, routers or server adapters. Ensure that the host devices support QSFP AOC modules and, if necessary, enable DDM/DOM in the device management interface to access diagnostic parameters. There is no need for separate transceivers or patch cords; handle the cable by the connector housings and avoid sharp bends along the multimode fiber section to preserve optical performance.

Usage recommendations

Verify compatibility with the network device vendor documentation before installation, confirm that DDM/DOM is supported if remote diagnostics are required, and route the cable to avoid tight bends and mechanical stress. For reliable operation, use the cable indoors in controlled environments and follow equipment manufacturer guidance for hot-plugging QSFP modules.
