Title: Douglas Fisher and Synchronous Data Transmission
Introduction
Douglas Fisher is an inventor associated with Reading, United Kingdom, and Nortel Networks Corporation. His work includes a patent for transmitting synchronous data across multiple signal paths.
Latest Patents
Fisher is credited with 1 patent, titled “Concatenated Transmission of Synchronous Data.” The invention describes splitting a multiplexed client signal into lower-rate signals, sending them over separate paths, and reassembling them at the destination. It removes carrier overhead before reassembly, allowing the original client signal to be recovered. The method supports bandwidth trading through virtual concatenation of synchronous optical channels and enables transparent transmission across intermediate networks that do not themselves support virtual concatenation.
Career Highlights
Fisher’s listed patent is associated with Nortel Networks Corporation. It addresses the practical challenge of carrying customer signals across varied network infrastructure while preserving the client signal through inverse multiplexing and reassembly.
Collaborations
Fisher’s named coworkers include Robert Friskney and Nigel Baker. The available information does not specify their roles in the patent or their particular contributions.
Conclusion
Douglas Fisher’s patent focuses on flexible synchronous data transport, using multiple signal paths to carry and reconstruct a client signal across networks with differing capabilities.
