Connects two network devices with SFP28 ports, including 25 GbE switches, servers, routers and adapters.

  • Recommended for data centers, high-end servers and enterprise wiring closets
  • Compatible with Arista, Cisco, Dell, Juniper and Mellanox equipment
  • Zinc die-cast male SFP28 connectors for superior EMI resistance
  • Ergonomic pull tabs for fast hot-swap connections/disconnections in crowded networks
  • Simpler alternative to fiber optics in short-range network connections


The Smart Solution for 25G Network Cable Connections
This Cisco-compatible SFP cable is recommended for fast, clear signal transmission in 25 Gbps networks in data centers, high-end server rooms and enterprise wiring closets. The N280-02M-28-BK is a cost-effective, low-power alternative to fiber optic cabling in high-speed interconnect applications, including network storage and enterprise networking. It conforms to SFF-8432 standards and is compatible with equipment open to third-party cables, including equipment from Cisco, Arista, Dell, Juniper and Mellanox.

Expert Construction for Reliable Data Transfers
The N280-02M-28-BK is ideal for network engineers, IT managers and installers working with servers, switches, adapters and routers that require connections through SFP28 ports at short range. Zinc die-cast male SFP28 connectors and flexible 30 AWG conductors resist EMI line noise and maintain smooth high-frequency response. Ergonomic pull tabs allow easy hot-swap connections and disconnections in crowded network components.

Fully Compliant to Fit Almost Any Application
In addition to fitting the latest SFP28 MSA (Multi-Source Agreement) SFF-8432 architecture, this cable meets or exceeds strict 25GBase-CR1 standards, as well as IEEE 802.3by and RoHS. Its male connectors fit all SFP28 ports and are the equivalent of Cisco’s SFP-H25G-CU2M cable.

System Requirements

Conforms to SFF-8432 standards and compatible with the following manufacturers’ equipment that are open to third-party cables: Arista, Cisco, Dell, Juniper, Mellanox (not compatible with HP)
