The demand for high speed data services continues to be rising, as carriers and service providers try to accommodate customers’ demands for high throughput broadband services and offer high throughput DWDM dark fiber managed services. Thus, the optical transport layer is pushed more and more toward the access and optical CPE which perform the mapping of the different client interfaces into the carrier OTN layer. Therefore, high bandwidth managed services can be offered and deployed easily as part of the carrier’s optical end to end DWDM infrastructure.
