## Summary description

The BlueOptics 54M38-BL is a 3 m InfiniBand/fibre optic cable featuring SFP28 connectors on both ends. Designed for high-speed data transmission, it ensures reliable connectivity in data centers and networking environments. The male/male configuration allows for easy connection to compatible devices, making it an ideal choice for enhancing network performance.

## Long description

The BlueOptics 54M38-BL is a 3 m InfiniBand/fibre optic cable with SFP28 connectors on both ends. Designed for short-reach, high-speed connections, this male-to-male SFP28 cable supports 25G data rates and is suitable for linking compatible switches, routers and storage devices within racks or between adjacent racks. The cable implements a passive direct-attach twinax copper design optimized for low latency and low power consumption in dense data center environments.
Advantages
The cable provides a fixed 3 m connection with SFP28 male connectors at both ends, enabling plug-and-play installation in equipment that supports SFP28 direct-attach cables. Its passive twinax construction offers low power usage and reduced latency compared with active optical solutions for short distances. Built to MSA-compliant specifications and using high-quality components, the cable is intended to deliver consistent electrical signal transmission for Ethernet, FCoE and InfiniBand applications up to 25 Gbit/s at the specified length.
Suitable for
Interconnects between switches in rack or adjacent-rack deployments
Connections between servers and top-of-rack switches supporting SFP28
Short-distance links for storage systems and SAN hardware
Key specifications
Connector type: SFP28 male to SFP28 male
Length: 3 meters
Data rate support: up to 25 Gbit/s
Cable type: passive twinax copper (direct-attach)
Wire gauge: 30 AWG
Standards: MSA-compliant for SFP28/DAC interconnects
How to use
Ensure both devices support passive SFP28 direct-attach twinax cables and support the intended transmission protocol (Ethernet, FCoE or InfiniBand) at 25 Gbit/s. Insert the SFP28 connector firmly into the transceiver slot of each device until the latch engages. Route the cable to avoid sharp bends and mechanical stress; maintain the specified 3 m separation and secure the cable to prevent strain on connectors. If a device vendor requires specific configuration or firmware compatibility, verify settings and update firmware as recommended by the hardware manufacturer before placing the link into production.
Usage recommendations
Use this passive 3 m SFP28 DAC where short-reach, cost-effective, low-latency links are required. Avoid using the twinax cable for runs longer than the specified 3 m and check device compatibility with passive DAC operation to ensure reliable performance.
