The amount of data traversing the cloud-datacenter is increasing exponentially, requiring more ports and higher-speed/port.
There are several major drivers for this growth:
1) Increased work-from-home, requiring workers to do more in the cloud
2) AI workloads, increasing data sent to/and from memory to GPUs to process data
As a result, datacenters require incessant demands on datarates, increasing from 10G-25G-100G-200G-400G. While the newest systems require 400G, 800G, and 1.6T per port, the major number of transceiver volumes are still dominated by the lower-speed datarates from 1G-10G-25G-100G. Hence, there still exists significant demand for 'legacy' products, especially in enterprise and non-hyperscale cloud-computing applications.
PhotonIC Advantage: CMOS vs. SiGe
Competitors for optoelectronic chips used in datacenter optics utilize an exotic SiGe process (8-inch wafer). While this special SiGe process has the best analog performance (Gain-Bandwidth) versus standard-CMOS (12-inch wafer), it has several major limitations:
PhotonIC is unique from its competitors, in that for our high-volume NRZ products (40G, 25G, 100G), we utilize a standard CMOS to operate at 25Gbps datarates for optical communications. Several patents have been filed and published, key IP that enables CMOS process to achieve the performance as a SiGe performance -- at half the price.
NOTE: While CMOS is good for some products that require intensive analog/digital integration, it is not optimized for analog-intensive applications. Hence, PhotonIC uses SiGe process where necessary, as well as CMOS process -- depending on product lines. For example, our active-copper-cable (ACC) products below are mostly analog, so we utilize SiGe for those.
