Data Center 200G QSFP56 Solutions

FIBERSTAMP focuses on the markets of cloud data center high-speed optical interconnection and provides a complete product solution for the path architectures of Next-Generation Data Center (NGDC) optical interconnects. Our products can cover 100G ports and then evolve to 200G ports based on PAM4 technology, and finally upgrade to 400G ports. The smooth upgrade path of the technology conformed to the laws of technology and market development.

Data Center Intra-connection

For the Data Center Intra-connection applications, we provide a complete 200G QSFP56 PAM4 optics portfolio with carrier-grade reliability. The optics are hermetically sealed and compliant with the stringent GR468-Core standard to meet the internal application requirements of ultra-large-scale data centers. The following table shows the pluggable optics that cover the transmission distance of 100m to 2km.

Product Name Part Number Reach
200G QSFP56 SR4 FST-200G-SR4 100m
200G QSFP56 AOC FSAP-200G-xxxM 100m
200G QSFP56 DR4 FST-200G-DR4 500m
200G QSFP56 UR4 FST-200G-UFR4 2km
  • 200G QSFP56 SR4 and 200G QSFP56 AOC reach up to 100m over 4 pairs of OM4 MMF
  • 200G QSFP56 DR4 reach up to 500m over 4 pairs of SMF
  • 200G QSFP56 UFR4 (with lower power consumption than FR4) reach up to 2km over a pair of SMF

Data Center Interconnection

To meet Data Center Interconnection (DCI) applications, there are several optical modules with transmission distances covering 10km to 40km.

Product Name Part Number Reach
200G QSFP56 LR4 FST-200G-LR4 10km
200G QSFP56 ER4 FST-200G-ER4 40km
  • 200G QSFP56 LR4 reach up to 10km or 20km over a pair of SMF
  • 200G QSFP56 ER4 reach up to 40km over a pair of SMF


Among the 200G PAM4 optics, the FIBERSTAMP's 200G QSFP56 LR4 optical module is in a leading position in the industry and has the following characteristics:

  • With excellent performance of Pre-FEC BER and Post-FEC BER, 100% FEC margin can be ensured.
  • Different brands switches are tested operating well through client interoperability compatibility testing.
  • With low-power optimization technology, the power consumption is less than 7W, which meets data center needs.
  • With automatic production line and excellent product consistency, timely and large-scale delivery can be ensured.
  • With PAM4 CDR based on DSP technology, excellent performance of the transmission can be ensured.

The 200G pluggable optics based on 50G PAM4 technology will surely become the only way for the next-generation data center. With the improvement of the 50G PAM4 ecosystem, the cost-effectiveness of FIBERSTAMP's 200G QSFP56 optics will be further highlighted. We believe that there is a very broad market space in the future for 200G QSFP56 PAM4 optics.
