QSFP-DD MSA to extend module bandwidth to 1.6 Tbps

The QSFP-DD Multi Source Agreement (MSA) plans to develop a new specification extending the bandwidth of the form factor to 1.6 Tbps. The new specification will leverage 200 Gbps serial PAM4 SerDes technology currently under development.The new specification will maintain the form factor’s eight lanes to provide an aggregate bandwidth capacity of 1.6 Tbps. The 1.6 Tbps module port will maintain backward compatibility with the entire family of QSFP...
