The performance of conventional add drop multiplexer (ADM) was limited due to greater cost involved in optical to electrical and electrical to optical conversions during addition and removal of wavelengths (information) along the line. Configurable optical add-drop multiplexers (COADMs) give the flexibility of adding or removing the wavelengths without the optical to electrical and electrical to optical conversions. Secondly, COADMs are very cost effective. This paper studies the performance of a 4 × 4 wavelength COADM. The performance at various wavelengths is compared on the basis of gain, noise figure and optical signal to noise ratio (OSNR).
