Huawei Optical Transmission SDH from Blueprint to Application



Synchronous Digital Hierarchy Overview

As IP networks are maintained and operated in a different way from Huawei SDH/MSTP networks.Carrier-class O&M requires visibility into the mysterious “cloud”, just like they do with traditional SDH/MSTP networks. This represents a big step forward in the shift from passive to proactive O&M.
 
In traditional SDH/MSTP-based bearer, factors affecting the QoS were relatively simple, and focus of operators was on network elements (NEs) and wireless coverage.
 
OTN introduction into an SDH network presents huge O&M challenges; the O&M workload increases significantly.
 
First, OTN devices themselves are more complicated. A piece of SDH equipment is basically a box of optical-fiber connections, making its O&M more easy.
