POET Technologies today announced that it has started sampling 400G FR4 and 800G 2xFR4 receive optical engines (RXOEs). POET will partner with Luxshare Technology Co., Ltd. (“LuxshareTech”), a global technology provider for data-communication facilities and enterprise-level products to enable the sale of power-efficient and cost-optimized 400G and 800G transceiver solutions.

"LuxshareTech is focused on expanding its 400G and 800G pluggable transceivers portfolio for the data center market,” said Mike Gao, GM of LuxshareTech’s Opto-electronic business unit. "We are pleased to work with POET Technologies and use their highly integrated chiplet platform to enable us to achieve a solution with superior performance and ease of compact module assembly.”

“The 400G and 800G FR4 RXOEs are the first of their kind to integrate photonic and electronic components on a single interposer chiplet. We expect customers to benefit from the simplified design, superior performance and lower cost offered by POET’s wafer-scale integration and passive assembly of components,” said Raju Kankipati, Vice President of Product Management at POET. “We are excited to work with LuxshareTech as a lead customer. LuxshareTech’s experience in designing and manufacturing high-speed optical transceivers and POET’s innovative technology can be mutually beneficial in bringing high-volume and low-cost solutions to the data center market.”

The POET 400G FR4 RXOE, produced by Super Photonics Xiamen, the Company’s JV, integrates a quad trans-impedance amplifier (TIA), four high-speed photodiodes and an optical demultiplexer integrated in a single chiplet measuring 12x5mm. The 800G 2xFR4 RXOE consists of an integrated octal trans-impedance amplifier (TIA), eight high-speed photodiodes and two optical demultiplexers in a single chiplet measuring 15x5mm. Customers of POET’s RXOEs have the option to procure the engines with integrated fiber array unit (FAU), which provides an even more complete solution for next-generation data center interconnects. The 400G and 800G RXOEs achieve superior performance through better integration of photodiodes and TIA and exceed the industry standard specifications for 400GBASE-FR4 interfaces.

POET expects to complete design verification testing and reliability qualification of the RXOEs in the first half of 2023 and start production in the second half of 2023.
