Hi Ranjeet,
Meanwhile, companies such as Wave-Splitter Technologies are pursuing the development of 25-GHz channel demultiplexing using arrayed-waveguide-grating routing technology and interleavers. Interleaving is frequently used in 50-GHz channel spacing. Basically, one set of 100-GHz-spaced channels or wavelengths is going in one direction and another set of wavelengths is going in the opposite direction.
The fiber Bragg grating technology that supports 25-GHz and 12.5-GHz channel spacing will allow carriers to increase the number of channels in the C-band without requiring other major component upgrades in the network, such as additional amplifiers, according to Ciena. The same technology could also be used in the L-band and S-band.
