Optical Carrier: The Backbone Of Modern Telecommunications Networks

Since the advent of the Internet and the World Wide Web, there has been a huge burst in the average consumer traffic. While consumers have been demanding larger bandwidth pipes, there real strain comes on the service provider networks that need to support this growing demand. Fortunately, with SONET technology, they need not invest in overhauling their networks every couple of years. The concept of Optical carrier has helped service providers stick to SONET and meet the growing bandwidth demands.

SONET technology uses the concept of synchronous frames that can be added and dropped from higher level frames with minimal computational complications. This is means that the traffic payload can be separated out from the overall traffic at any level of the hierarchy and this is invaluable for growing bandwidth demands. This is the primary reason for the longevity of SONET.

The fundamental unit of SONET networks is the STS-1 frame. Interestingly, this unit is processed only at the electrical level. Typically, there is no optical equivalent of STS-1. This means that within SONET, there is no link that can actually transmit a single STS-1 frame. However at 51.84 Mbps, this is the important bridge between the PDH and SONET networks.

The fundamental transport link in SONET is the OC3. This signal is basically aggregation of three STS-1 frames in the electrical domain. The electrical equivalent of OC3 is STS-3 and its link rate is thrice STS-1 or 155.52 Mbps.

The OC3 links are ideal for connecting large commercial buildings to the main central office transport networks. The reason is that these customer locations have sufficient base for high volumes of traffic. While OC3 links are great to link high density customer locations, the remote central offices are best linked using the next level of Optical carriers: OC12.

The OC3 and OC12 are great for linking low concentration of traffic. However, as one moves towards the network core the demands cannot be satisfied by these links. This is where links like the OC192 with nearly 10 Gbps capacity become important. As the name suggests, this has the capacity of 16 OC12 links and is ideal for the present core demands.

As described above, there is a SONET hierarchy Optical carrier for every section of the network. What this means for the service provider is that they can reuse their existing infrastructure and keep upgrading and appending capacity to it. Truly, SONET is a big blessing for the service providers and ultimately to the end users.
