## Summary description

The BlueOptics 295-1137-BL is a 3 m InfiniBand/fibre optic cable with QSFP connectors. It features male/male connectors for reliable data transmission. Ideal for high-speed networking applications.

## Long description

The BlueOptics InfiniBand/fibre optic cable 3 m QSFP Black is a 3-metre high-speed link with QSFP-to-QSFP connectors designed for short-reach data centre interconnects. It is specified for 40GBase-CR4 and InfiniBand applications and implements a passive direct attach twinax copper design suitable for rack-to-rack and intra-rack connections. The cable uses male QSFP connectors on both ends and follows MSA-compliant physical and electrical characteristics for compatibility with major switching, routing and storage platforms that accept passive 40G DAC links.
Advantages
This cable provides a low-latency, low-power connection for 40 Gbit/s links over a 3 m distance. As a passive Direct Attach Cable (DAC) it does not require additional transceivers or active components, resulting in reduced power consumption and simplified installation. Manufacturing to common MSA guidelines and the use of established cable and component suppliers aim to deliver stable electrical performance and long operational lifetime for data centre environments.
Suitable for
 40 Gigabit Ethernet (40GBase-CR4) short-reach links
 InfiniBand high-speed interconnects
 Direct connections between switches, routers and storage within or across adjacent racks
 FCoE and Fibre Channel applications that accept passive DAC cabling
Key specifications
 Length: 3 metres
 Connector type: QSFP male to QSFP male
 Data rate support: up to 40 Gbit/s
 Cable type: passive twinax copper (DAC), 30 AWG
 Application: 40GBase-CR4, InfiniBand, FCoE, Fibre Channel (short-reach)
 Compliance: MSA-compatible mechanical and electrical characteristics
 Typical use: rack and adjacent rack interconnects in data centres
How to use
Verify that the network equipment explicitly supports passive 40G DAC connections and QSFP direct-attach cables. Insert each QSFP connector into the appropriate QSFP port on your switches, routers or storage devices until the latch engages. Ensure both ends are seated and the link status indicators on the devices report a valid 40G connection. For best signal integrity, route the cable without tight bends and avoid sharp kinks; keep the length suitable for the intended rack spacing (3 m).
Usage recommendations
Use this passive BlueOptics 3 m QSFP DAC for short-distance, high-throughput links where low latency and low power consumption are priorities. Confirm device compatibility with passive twinax cables before deployment and perform an initial link test after installation. Avoid running the cable alongside high-power conductors and maintain bend radius recommendations to preserve long-term performance.
