A long-haul optical transport network spans thousands of miles – say New York to Los Angeles. Each section typically carries in excess of 10 terabits per second of data. These are very high performance, high speed, and high-capacity networks. Several innovative technologies expected to revolutionize long-haul networks are just around the corner.
On the transponder side, there are new DSPs with higher baud rates and more advanced signal processing and measurement capabilities offering real time measurement of line conditions coupled with the ability to self-adjust in order to optimize performance.
Regarding ROADM technology, continuous C+L will support C-Band and L-Band waves from the same WSS, forward Raman amplifiers will complement backward Raman technology to further extend reach and new integrated fiber distribution panels will reduce installation complexity by more than half. New thermal management techniques will complement this to reduce power and provide a “greener network.”
It’s a big list, and when you put it all together, you get a new generation of reliable long-haul networks which are easier to operate and maintain, with a lower cost per bit than ever before.
