Direct-attach copper cable for 25 GbE links

This Mellanox SFP28 passive copper cable provides a cost-effective alternative to fibre for 25 GbE Ethernet connections. It uses a single high-speed copper pair operating at data rates up to 25 Gb/s. The one-metre assembly complies with the SFF-8402 SFP28 standard and includes an EEPROM readable by the host system. It is suited for short-distance interconnects in data-centre environments.

CA-25G-N compliance with low latency

Cables up to two metres support IEEE 802.3 by CA-25G-N with low latency and no forward error correction. Longer assemblies from four to five metres use CA-25G-L with RS-FEC enabled, while 2.5 m and 3 m versions exist for either class. This one-metre unit therefore installs without FEC overhead. Rigorous production testing aims to ensure reliable out-of-the-box performance.

30 AWG gauge limits reach to short runs

The cable is built with 30 AWG conductors, which constrains its practical use to very short links such as adjacent rack equipment. Buyers needing longer spans must select a heavier-gauge or active cable not described here. The black jacket and SFP28 connectors on both ends complete the physical specification.

Questions about this item

Does the 30AWG copper pair need any periodic replacement or re-termination?

No, the passive copper assembly is tested for durability and requires no scheduled maintenance or re-termination during its service life.

What limits the 25Gb/s throughput first when the link runs continuously?

The 1 metre CA-25G-N assembly operates without forward error correction, so signal integrity over the copper pair is the first limiting factor under sustained load.

How much heat or noise does the cable add when it carries 25GbE traffic all day?

The passive design draws no power and generates no audible noise, so it adds negligible heat to the rack environment.
