Product information

Description

The BlueOptics ET7302-DAC-50CM-BL is a 0.5 m InfiniBand/fibre optic direct attach cable with SFP28 male-to-male connectors designed for short-reach, high-speed connections in data centers and high-performance computing environments. This passive twinax copper cable conforms to 25GBase-CR signaling and the SFP28 MSA for reliable 25 Gbit/s links over 0.5 m. The cable is intended for direct, low-latency electrical signal transfer between compatible SFP28 ports on switches, routers, storage systems and servers.

Advantages

The cable delivers up to 25 Gbit/s data rates with low power consumption and low latency thanks to its passive twinax design. Compliance with SFP28 and MSA guidelines ensures predictable interoperability with hardware platforms that support 25GBase-CR SFP28 direct attach cables. The 0.5 m length is suitable for rack-to-rack or in-rack connections, reducing clutter while providing a compact, robust physical interface. High-quality components and industry-standard manufacturing practices contribute to long service life and high availability.

Suitable for

  • Short-reach links between SFP28 ports in racks and adjacent racks
  • 25G Ethernet, FCoE and InfiniBand applications requiring 25 Gbit/s over short distances
  • Connections between switches, routers, storage arrays and servers with SFP28 support

Key specifications

  • Length: 0.5 m
  • Connector type: SFP28 male to SFP28 male
  • Data rate: up to 25 Gbit/s
  • Cable type: passive twinax copper (30 AWG)
  • Compliant with 25GBase-CR signaling and SFP28 MSA
  • Typical applications: Ethernet, FCoE, Fibre Channel, InfiniBand (short reach)

How to use

Install the cable by seating each SFP28 connector into the corresponding SFP28 port on the network devices until the latch engages. Ensure devices are powered and configured to support passive DAC twinax cables and 25GBase-CR operation. Verify link status and negotiate speed on both endpoints. Avoid sharp bends and tensile stress on the cable; maintain recommended bend radius to preserve signal integrity. If a device does not recognize the cable, check port compatibility and firmware or software settings that may restrict third-party DAC modules.

Usage recommendations

Use this 0.5 m BlueOptics direct attach cable for short, fixed connections inside racks or between adjacent racks where low latency and low power consumption are priorities. Confirm that your hardware supports passive SFP28 DACs at 25G and, when possible, test one unit in your environment to ensure full compatibility with your specific switches or storage systems.
