Applied Optoelectronics (AOI) has begun sampling 400G optical modules designed to demonstrate the feasibility of on-board optics (OBO), as outlined in specifications such as the recently-released version 1.1 of the onboard optical module specification published by the Consortium for Onboard Optics (COBO). AOI is an active member of COBO.
In contrast to traditional pluggable optical modules, OBO modules are designed to be used in higher-speed data...
