On ECOC 2019, Gigalight successfully demonstrated 400G QSFP-DD SR8 optical transceiver based on 50G PAM4 and 200G QSFP56 FR4/LR4 optical transceiver applicable to 5G backhaul and data center, which aroused great interest of visiting customers and industry colleagues.
Gigalight 200G QSFP56 FR4/LR4 Optical Transceiver
The design of 200G QSFP56 LR4 and 200G QSFP56 FR4 optical transceivers adopt the frame of EML laser and DSP, which can meet the requirements of 0-70℃ commercial applications. The 200G QSFP56 LR4 optical transceiver has a maximum operating power of 7.5w at high temperature, while a transmission distance of 20km in full compliance with the protocol BER requirements, and the FEC margin of 100% excellent performance. 200G QSFP56 FR4 adopts CWDM EML laser with refrigeration, the maximum power consumption at high temperature is 7.0w, and the transmission distance is also 20km in full compliance with the protocol BER requirements. The updated version of 200G QSFP56 FR4 can reduce the power consumption to about 6W and meet the standard transmission distance of 2km if it meets the requirements of the data center.
By September 2019, Gigalight has released three commercial temperature 200G products based on PAM4 technology, namely 200G QSFP56 SR4, 200G QSFP56 FR4 and 200G QSFP56 LR4. These products all adopt self-developed and self-packaged high-speed optical devices, showing excellent performance enough to show that Gigalight has fully mastered the optical transceiver technology based on 50G PAM4 platform.
The 200G optical transceiver based on 50G PAM4 technology is in the early stage. Gigalight has launched 200G QSFP56 SR4 in early 2019, which is suitable for data center and high performance computing. The product adopts Gigalight‘s self-developed optical engine, with the maximum power consumption of 5W under high temperature, and has been tested and operated well in numerous clients. Gigalight also plans to release a low power version of 200G QSFP56 DR4 transceiver, further enrich the data center of the parallel solution in this year.
