Metropolitan WDM: Fact or Fallacy? The Requirements for Regional Reach in Metro Applications

Abstract

The term “metro DWDM” was first used to describe systems designed or packaged for fiber exhaust applications in local networks. Mainly targeted towards CLECs, the systems were non-amplified, point-to-point, and cheaper than new fiber. Essentially, they were a scaled-down adaptation of long haul (LH) DWDM. The removal of amplifiers helped to lower the cost while reducing the system’s reach significantly. However, this limitation seemed to aptly accommodate distances in the tens of kilometers found in the metro. Sometimes, booster amps were used immediately adjacent to the terminal equipment to overcome attenuation caused by low cost multiplexers. As DWDM topologies migrated to rings, it became expensive to use terminal multiplexer filters because each wavelength had to be dropped at each node.
