In ultra long haul high speed communications, optical link budget and dispersion are the two major obstacles engineers encounter with. Dispersion is the phenomenon in which the phase velocity of a wave depends on its frequency (wavelength). It is sometimes called chromatic dispersion due to the wavelength dependency nature. This issue becomes prominent for higher data rate (shorter pulse width) as well as longer transmission distance.
It is an optical line protection service board which provides low-cost redundant solution for broadband transmission networks. The main feature of this card is it is easy to install and it provide backup solution.
Rackmount chassis for various network cards. Featuring 1+1 redundant power supplies, 18 slots of (1 slot for system control card, 2 slots for power supplies & 15x slots for network cards).
