Book excerpt: This chapter provides a global network service provider’s view on the technology development and product commercialization of 100-Gb/s for optical transport networks. Optical channel capacity has been growing over the past four decades to address traffic demand growth and will continue this trend for the foreseeable future to meet the ever-increasing bandwidth requirements. In this chapter, optical channels are re-classified into three basic design types. Commercial 100-Gb/s channel development experienced all three types of channel designs before eventually settling on the single carrier PM-QPSK format with coherent detection, which appears to be the optimal design in the industry. A series of 100-Gb/s channel related field trials were performed in service providers’ networks to validate the technical merits as well as business advantages of this new capacity standard before its deployment. Introduction of the 100-Gb/s channel brings new opportunities to boost fiber capacity, accommodate increases in client interface speed rates, lower transmission latency, simplify network management, and speed up the realization of next generation optical add/drop functions.
