InfiniBand/optický kabel BlueOptics CBL-NTWK-0944-MS28C20M-BL 2 m SFP28 samec/samec

The BlueOptics CBL-NTWK-0944-MS28C20M-BL is a 2 m InfiniBand/fibre optic cable with SFP28 male connectors on both ends. Designed for short-reach, high-speed links in racks and adjacent rack rows, this cable supports 25GBase-CR applications and is suitable for Ethernet, FCoE and InfiniBand traffic up to 25 Gbit/s over a 2 metre distance. The cable follows MSA-compliant SFP28 form-factor conventions and is intended for use where reliable, low-latency connections are required between switches, servers and storage devices.

Advantages

The cable combines a standardized SFP28-to-SFP28 interface with a 2 m length optimized for data center rack wiring, offering low latency and low power consumption typical of passive direct-attach twinax solutions. Manufactured using high-quality components and tested for compatibility with major hardware platforms, it provides consistent signal integrity and a service life designed for professional installations.

Suitable for

• Short-reach connections between switches in a rack or adjacent racks
• Server-to-switch direct links in data centers
• Storage system interconnects supporting 25G applications
• Environments requiring low-latency, low-power physical links

Key specifications

• Connector type: SFP28 male to SFP28 male
• Length: 2 metres
• Supported data rate: up to 25 Gbit/s
• Cable type: passive twinax copper (direct attach cable)
• Wire gauge: 30 AWG
• MSA-compliant SFP28 form factor
• Typical applications: Ethernet, FCoE, InfiniBand

How to use

Install the cable by inserting each SFP28 connector into the corresponding SFP28 port on your devices until the latch engages. Confirm that connected hardware supports passive 25GBase-CR direct attach twinax cables and check link status through device management interfaces. For best results, route the cable within the rack to avoid sharp bends and mechanical stress; maintain the 2 m separation for which the cable is specified.

Recommendations

Use this 2 m SFP28 direct attach cable for short copper links inside racks or between adjacent racks. Verify device compatibility with passive DACs, avoid tight bending radii, and keep connectors clean and free from dust. For longer distances or fibre-based infrastructure, select an appropriate optical transceiver and fibre cable instead.
