Introduction

Johnny Zhong is a prominent inventor based in Union City, CA (US). He has made significant contributions to the field of optical communications, holding a total of 12 patents. His work focuses on enhancing bandwidth and communication capacity through innovative technologies.

Latest Patents

One of Johnny Zhong's latest patents is the Optical Add/Drop Module, which is a WDM add/drop module. The drop portion of this module utilizes thin film filters or thin film interleavers. The add portion employs fused fiber interleavers for the less critical stages of the multiplexing process. In the final stage, fused fiber interleavers can be placed in series. A thin film interleaver with a flattop frequency response may also be used for the critical stage, where the multiplexed channels are closely spaced. This design ensures a relatively constant frequency response across a channel's bandwidth while minimizing cross talk at the channel edges.

Another notable patent is the Scalable and Movable DWDM Usage of CWDM Networks. This innovation provides systems and methods for integrating DWDM modules into existing CWDM systems, thereby increasing bandwidth without the need to replace current infrastructure. The DWDM modules can be transparently inserted into CWDM systems by reserving channels for DWDM use. This allows for a scalable number of DWDM wavelength channels, such as four, eight, or sixteen, to be utilized in both single and dual fiber systems, as well as ring systems.
