Feature Issue on Optical Performance Monitoring (OPM). The next-generation integrated performance monitor (NGIOPM) will prove to be a necessary tool for MCI to monitor and maintain its optical transmission network. The functions and requirements described for NGIOPM are intended for incorporation into various transmission network elements such as add-drop multiplexers (ADMs), optical cross-connect switching, regenerators, and other optical components. The NGIOPM will (i) provide transmission integrity including guaranteed performance to customers service-level agreements (SLAs) as well as meeting company engineered transmission performance objectives; (ii) reduce costs by eliminating or decreasing labor intensive testing; and (iii) increase network reliability by reducing network downtime.
