Product information

Description

SFP28 Direct Attach Cable BlueOptics SFP-H25G-CU2M 25GBASE-CR 2 m is a passive copper twinax cable designed for short-reach 25 Gb/s links. Intended for use with SFP28 ports, this 2-meter cable provides a direct attach solution for connecting switches, network interface cards (NICs) and servers in rack and data centre environments. The cable supports 25GBASE-CR signalling and offers a simple, low-latency physical connection without the need for transceivers or fibre handling.

Advantages

The BlueOptics SFP-H25G-CU2M delivers reliable 25 Gb/s connectivity with lower power consumption compared to active optics. Its passive twinax construction reduces latency and provides consistent signal quality for short distances up to 2 meters. The integrated SFP28 connectors simplify installation and eliminate separate transceiver units, lowering hardware complexity in top-of-rack and server-to-switch deployments.

Suitable for

  • Direct switch-to-switch connections within racks
  • Server or NIC to switch links in data centres
  • Short-reach 25 Gb/s uplinks and cross-connects
  • High-density networking installations where low power and low latency are required

Key specifications

  • Interface: SFP28 to SFP28 (direct attach)
  • Data rate: 25 Gigabit per second
  • Physical medium: Passive twinax copper
  • Length: 2 meters
  • Typical use-case range: short-reach, within rack or adjacent racks
  • Latency: low, passive connection without optical conversion
  • Power: passive cable with no additional power requirement for the link

How to use

Insert each SFP28 connector into the corresponding SFP28 ports on the devices to be connected, ensuring the latch engages to secure the connection. Verify that both devices are configured for 25 Gb/s operation and that any required interface settings or link aggregation are applied at the switch or host. No additional transceivers or fibre handling are required; the cable functions as a direct copper link between compatible SFP28 ports.

Usage recommendations

Use this 2 m passive copper cable for short, high-bandwidth links inside racks or between adjacent racks. Confirm port compatibility and firmware support on switches and NICs before deployment. Avoid sharp bends and excessive pulling force to preserve signal integrity and connector reliability.
