Abstract:

The development of the physical layer for a high speed 10 Gigabitssec fiber optic wide area network, implementable by the Air Force in a five to ten year timeframe is addressed. First, to gain a generally acceptable degree of survivability while maintaining efficiency, it is concluded that a counter-rotating ring physical topology is most appropriate. To obtain high link capacity, links will consist of multiple channels, each operating at data rates manageable using switching. Then, for efficient information transfer in a multi- service environment, each channel will operate with Asynchronous Transfer Mode ATM, a fast packet switching technique. Many common logical network topologies are then overlayed onto this physical multichannel ATM ring foundation. Based on comparisons relative to several important criteria, a logical multi-ring architecture, with wavelength division multiplexing, is concluded to be the most promising alternative. An investigation of the media level implementation of this network, using the example of an eight channel link where each channel operates at 2.49 Gbps, shows that symmetrical, single-mode grating-based wavelength division demultiplexers and traveling wave optical amplifiers can be used to create bidirectional multichannel link spans exceeding 2000 km without electronic regeneration.
