Product Review

The Arista CAB-S-S-25G-3M supports up to 25Gb/s bi-directional data links and is compliant with both SFF-8402 and IEEE 802.3by, making it versatile for 25GBASE Ethernet applications. Its design incorporates AC coupled inputs and outputs and an enhanced EMI design, ensuring signal integrity and reduced electromagnetic interference across a 3.0m reach. However, the cable's reliance on a single 3.3V supply voltage and specific operating temperature and humidity ranges may limit its use in extreme conditions or environments outside the specified parameters.


The Arista CAB-S-S-25G-3M is designed for high-speed data transmission, providing up to 25Gb/s bi-directional data links. It is a passive copper cable with a length of 3.0 meters (9.8 feet), making it suitable for short-range connections between networking hardware. This cable is optimized for 25GBASE Ethernet applications, ensuring compatibility with the latest networking standards. Key features include compliance with SFF-8402, ensuring it meets the standards for SFP28 interfaces. It operates on a single 3.3V supply voltage, with both inputs and outputs being AC coupled. The design is hot pluggable, allowing for easy installation and removal without the need to power down the network system. With a 100 Ohm differential impedance, it is engineered to minimize signal loss and ensure reliable data transmission. The cable's construction includes a 28AWG wire gauge, which strikes a balance between flexibility and durability. This ensures that the cable can be easily routed through tight spaces without compromising on performance. Enhanced EMI design reduces electromagnetic interference, maintaining signal integrity even in environments with high electronic noise.
  • Compliance with IEEE 802.3by and RoHS standards indicates adherence to strict environmental and operational guidelines.
  • Operational efficiency is maintained across a wide range of temperatures and humidity levels, with operating case temperatures ranging from 0°C to 70°C and storage temperatures from -40°C to 85°C.
  • A relative humidity range from 5% to 85% (non-condensing) ensures performance in diverse environmental conditions.
Power requirements are minimal, with an input voltage range of 3.14V to 3.46V and a maximum power supply current of 4 mA, minimizing the energy footprint of network operations. The cable supports a data rate of 25 Gb/s, facilitating rapid data transfer and bandwidth-intensive applications. Cable impedance is specified between 90 Ohm and 110 Ohm, accommodating a range of network configurations and ensuring compatibility with a variety of devices. This specification is critical for maintaining signal quality over the length of the cable. In summary, the Arista CAB-S-S-25G-3M cable is a high-performance solution for connecting network devices over short distances. It combines high data transfer rates with compliance to industry standards and is built to operate reliably in a wide range of environmental conditions. Its design considerations for power efficiency, EMI reduction, and physical flexibility make it a versatile choice for modern data centers and networking environments.
