FAQ

What is the breakout configuration?

The cable connects one 200G QSFP56 port to two independent 100G QSFP56 ports, allowing a 200G uplink to connect directly with two 100G interfaces.

Is this DAC active or passive?

It is a passive Direct Attach Copper Cable using twinax copper conductors, which helps minimize power consumption and provides a cost-effective solution for short-distance connections.

What signaling technology does it use?

The cable uses four PAM4 transmission channels, with each channel supporting up to 56Gbps for 200G-class aggregate connectivity.

What cable gauges and lengths are available?

The cable is available in 26 AWG and 30 AWG configurations, with lengths up to 3 meters for short-distance data center and high-density rack applications.

Why is the eight-pair copper design important?

The eight differential copper pairs are optimized for high-speed PAM4 transmission, helping control insertion loss and crosstalk to maintain reliable signal integrity at 200G data rates.
