200G QSFP56 & QSFP-DD

The 200G optical module landscape is defined by two main types: 200G QSFP56 and 200G QSFP-DD. Each offers unique advantages in performance and compatibility, meeting the needs of modern data centers and high-speed networks.

200G QSFP56: As an evolution of the 40G QSFP+ and 100G QSFP28, the QSFP56 (Quad 50 Gigabits Small Form-factor Pluggable) is designed specifically for 200G Ethernet. It supports 4 x 50G channels, enabling higher network speeds. The key innovation in the QSFP56 is the transition from NRZ to PAM4 encoding, allowing for greater data rates and efficiency.

200G QSFP-DD: The QSFP-DD (Quad Small Form Factor Pluggable Double-density) transceiver complies with IEEE802.3bs and QSFP-DD MSA standards. Its “double-density” design supports twice the number of high-speed electrical interfaces compared to QSFP28. With NRZ modulation, it achieves data rates of 25G x 8 for 200G networks, while PAM4 modulation enables 50G x 4 for 400G networks. This makes it ideal for high-performance computing and cloud networks.

There are two main technical approaches for 200G modules:

• 4x50G PAM4 in the QSFP56 package for superior performance and data handling.
• 8x25G NRZ in the QSFP-DD package for low power consumption, reduced latency, and cost-effective deployment within data centers.

KanesBridge provides cutting-edge solutions with the following 200G optical modules: 200G QSFP56 SR4, 200G QSFP56 LR4, and 200G QSFP-DD SR4.
