Long-Haul Network Testing
Long-haul networks carry a lot more data than any type of network, and over much greater distances. Optically speaking, they require the most complex testing-chromatic dispersion (CD) and polarization-mode dispersion (PMD) being some of the parameters to keep in check.
High bit rates and synchronized data transmission put prime importance on detailed testing of the SONET/SDH infrastructure. Parameters such as data integrity, delays, amplification and attenuation become far more critical to control, at every step of the networks' life cycle.
