Wavelength Division Multiplexing (WDM) systems use different types of sites to manage signal transmission and amplification across long distances. These include:

OLA (Optical Line Amplifier):Amplifies optical signals to compensate for losses over long distances.

OTM (Optical Terminal Multiplexer):Located at the endpoints of the WDM system, it multiplexes and demultiplexes wavelengths.

REG (Regenerator):Regenerates optical signals to restore their quality after significant attenuation.

OADM (Optical Add-Drop Multiplexer):Adds or drops specific wavelengths at intermediate points without affecting others.

Each type of site plays a critical role in ensuring efficient and reliable operation of WDM networks.
