## Summary description

The BlueOptics SFP-25G-C2M-BL is a 2 m InfiniBand/fibre optic cable with SFP28 connectors. It features male/male connectors for reliable data transmission. Ideal for high-speed networking applications.

## Long description

The BlueOptics SFP-25G-C2M-BL is a 2 m Direct Attach Cable (DAC) with SFP28 male-to-male connectors designed for high-speed short-reach links. It supports 25GBase-CR electrical transmission and is suitable for Ethernet, Fibre Channel over Ethernet (FCoE) and InfiniBand environments when used with compatible SFP28 ports. The cable implements passive twinax copper construction with 30 AWG conductors and is MSA-compliant, enabling direct rack-to-rack and intra-rack connections between switches, routers and storage systems that accept SFP28 DACs.
Advantages
This 2 m SFP28-to-SFP28 DAC offers low latency and low power consumption compared with active optical modules, making it efficient for short distances in data center environments. Manufactured to MSA specifications and using high-quality components, the cable provides stable electrical signalling for 25 Gbps links and is compatible with major hardware platforms that support 25GBase-CR passive DACs. The passive twinax design reduces complexity and potential failure points, contributing to long operational lifetime and predictable performance.
Suitable for
Short-reach 25 Gbps connections between network switches
Direct connections between servers and storage systems with SFP28 ports
Top-of-rack and adjacent-rack interconnects in data centers
Environments using Ethernet, FCoE or InfiniBand protocols at 25G
Key specifications
Connector type: SFP28 male to SFP28 male (twinax)
Length: 2 meters
Data rate: up to 25 Gbps
Cable type: passive twinax copper, 30 AWG conductors
Standards: MSA-compliant for SFP28 25GBase-CR applications
Power consumption: passive operation (very low power)
How to use
Insert each SFP28 connector into the corresponding SFP28 port on the devices to be linked, ensuring ports support passive 25GBase-CR DACs. Route the 2 m cable to avoid sharp bends and mechanical strain; use gentle cable management to maintain signal integrity. No external power or configuration is required for the cable itself, but verify device firmware and port settings to enable 25 Gbps operation and the intended protocol (Ethernet, FCoE or InfiniBand).
Usage recommendations
For reliable operation, confirm host and switch compatibility with passive SFP28 DACs and update device firmware where necessary. Avoid excessive bending radius, protect the cable from prolonged compression, and use appropriate rack cable management to reduce stress. For critical links, consider testing a sample in your specific hardware setup to validate link training and protocol support before wide deployment.
