Solarflare Communications has begun sampling what it claims is the first 40nm quad-port 10GBASE-T PHY chip.

The SFT9104 is Solarflare's fourth-generation PHY and has passed testing on links up to 100m, meeting a critical requirement in the 10GBASE-T standard for broad deployment.

According to Solarflare, the SFT9104 achieves 100-meter reach at one-third the power consumption of competitive products. Under normal 100m operation, the SFT9104 consumes just 2.5W per port. The chip has multiple data center power modes, including a 1.5W low power and latency mode for in-the-rack applications.

The SFT9104 is fully backwards compatible with both 1000BASE-T and 100BASE-TX, enabling seamless integration while preserving investments in existing infrastructures.

The SFT9104 is now sampling to key customers. Production schedule is slated in Q4.
