Different protection and restoration mechanism is the most important feature of automatic switched optical network (ASON). Through testing 1356NT, which is an optical network planning and design tool of Alcatel-Lucent Company, this paper analyzes the restoration time and proposes the application strategy of different circuits. It is significant for the plan and design of ASON. Keywords-automati...

An optical package for mounting VCSEL and PIN diodes for transmitting and receiving optical signals has been developed. The diodes couple to the fibers in a commercial MT connector. The package is quite compact with its physical size significantly smaller than that of the MT connector. This design simplifies the testing and assembly of the optical components because the MT connector with the lo...
