Optical Networking

Optical modules enable high-speed data path connections within the data center switching network, as well as to the external core and metro telecommunications network. PAM-4 based DSPs are primarily used within the data center switching network as they are cost-optimized for shorter ranges, while coherent optics DSPs are better suited for longer distances. Module form factors have greatly reduced in size over the past 5 years, fueled by a high degree of component integration into the DSP. Selecting a high performance, low-jitter reference clock source to the DSP is essential to maximizing bandwidth speeds and minimizing bit error rate.
