An OC-48 SONET optical transmission system for gigabit computer networks

Results on the performance characteristics of four experimental prototype 2.5 Gb/s SONET optical transmission systems to be deployed in gigabit computer networks are presented. The long-term error performance of the systems has been evaluated with measured ultra low error rates of less than 10/sup -15/. This level of performance is an important feature in the design of high-speed computer communication networks. It also demonstrated that for a nonreturn-to-zero (NRZ) modulated 1310-nm transmitter, a negative dispersion penalty can be achieved for up to 200 km by using dispersion-shifted single mode fiber (DS-SMF). Therefore, DS-SMFs have a potential advantage over conventional SMFs for dual-window multi-Gb/s transmission systems, particularly for wavelength division multiplexed applications.<<ETX>>
