Latest Patents

Feng’s listed patent, “Optical-Line Terminating Device and Optical Communications System,” describes an optical line terminal (OLT) designed to manage power use across its transceivers. The OLT includes separate transceivers and control units for communicating with groups of optical network units (ONUs), along with a power supply and an OLT processing unit.

When the number of ONUs in either group falls below a predetermined threshold, the processing unit directs the corresponding control unit to turn off power to that group’s transceiver for a specified period. This approach is intended to reduce power consumption while maintaining separate control of the two optical communication paths.

Career Highlights

Feng’s listed patent reflects work in optical communications, particularly in controlling the power consumption of network equipment. The available details identify Mitsubishi Electric Corporation as his company and Tokyo, Japan, as his location.

Collaborations

Feng’s listed coworker is Satoshi Yoshima. The patent description concerns an OLT system with coordinated transceiver controls, though the available information does not specify individual contributions.

Conclusion

Chengguang Feng’s listed patent addresses energy management in optical communications by enabling an OLT to power down transceivers when their associated ONU groups fall below a set threshold.
