BlueOptics ET6402-AOC-1M-BO InfiniBand Fibre Optic Cable 1m QSFP Male

The BlueOptics ET6402-AOC-1M-BO InfiniBand Fibre Optic Cable 1m QSFP Male is a 1‑meter active optical cable (AOC) with QSFP male connectors on both ends designed for high‑speed, short‑reach interconnects in data centers and network racks. It integrates optical transmitter and receiver assemblies on each end and is compatible with 40GBASE‑SR4 applications and InfiniBand QSFP ports following common MSA form‑factor specifications. The cable supports low latency, high bandwidth links between switches, servers and storage systems while using multimode fiber for reliable signal transmission over the one‑meter span.

Advantages

The cable offers a compact QSFP‑to‑QSFP connection that eliminates separate transceivers, reducing port footprint and simplifying installation. As an active optical cable it provides electrical isolation and reduced heat compared with equivalent copper cables, while maintaining 40 Gbps class performance for Ethernet, Fibre Channel over Ethernet and InfiniBand interconnects. Its one‑meter length is suitable for short‑reach patching inside racks where predictable latency and signal integrity are required.

Suitable for

• Connecting QSFP ports between switches and aggregation devices inside server racks
• Direct links between high‑performance servers and storage arrays
• Short‑reach InfiniBand connections in HPC and cluster environments
• 40GBASE‑SR4 optical interconnects for data center patching

Key specifications

• Length: 1 meter
• Connector type: QSFP (male) on both ends
• Type: Active Optical Cable (AOC)
• Supported data rate: up to 40 Gbps aggregate (40G class)
• Application: 40GBASE‑SR4, InfiniBand, Fibre Channel over Ethernet compatible
• Fiber type: multimode fiber with integrated transceiver modules
• Form factor: QSFP MSA compliant

How to use

Install the cable by inserting the QSFP male connectors into QSFP ports on compatible switches, servers or storage devices until the connector latch engages. Ensure both ends are populated with QSFP ports that support 40GBASE‑SR4 or InfiniBand QSFP operation. No separate SFP/QSFP transceivers are required. Verify link status on connected devices and check interface settings to confirm negotiated speed and protocol. For best results, route the cable within the same rack or between adjacent racks to maintain the short‑reach design intent.

Usage recommendations

Avoid excessive bending and mechanical stress on the cable; maintain manufacturer minimum bend radius. Keep the optical connectors and QSFP cages free of dust and secure the cable to prevent strain on the connectors. When replacing equipment, power down ports if recommended by the hardware vendor before hot‑swapping to reduce risk of port damage.
