First product combining electronics and photonics 1. How are the 400G and 800G FR4 RXOE for LuxshareTech better than what's currently on the market?
The POET 400G and 800G FR4 RXOEs are highly integrated solutions, combining electronics and photonics components in close proximity, which is essential for optimal performance at such high speeds. The optical signal gets converted to electrical signal by the photodiodes and the small electrical signal has to be immediately amplified by the TIA to enhance the quality of the received signal. The close integration of the TIA and the other components on the POET RXOE chiplet promises superior performance compared to discrete solutions. Those require assembly of the TIA, high-speed photodiodes and optical demultiplexer as separate components on the transceiver circuit board, all using wire bonds. The POET solution is a single chip that includes all of these components, pre-assembled and tested at wafer scale. It’s one of the reasons this technology can be a game-changer in cost, scale and performance for the industry.
3. What about these products is similar to what POET has sent
to ADVA? And what about these ones is different?
These 400G/800G RXOEs and the ADVA OEs that we announced on January 18th are both for data center applications. They both serve the 2km to 10km reach needs within the data center. However, the products for ADVA are for 100Gbps applications whereas these RXOEs for LuxshareTech are for higher speed applications, 400G and 800Gbps. The other major difference is the inclusion of TIA on the 400G and 800G RXOEs, which is not integrated on our OE for ADVA’s engines. The ADVA OEs are for a particular data center need, having to do with optimizing the use of legacy 100G ports. The 400G/800G RXdOEs are chiplets that will be included in fully functional 400G and 800G transceiver modules for general use. POET expects to combine these with its 400G/800G transmit OEs when they are available.
