Zusammenfassung:An OADM filter is integrated into the optics package of optical receivers and transmitters of a wavelength division multiplexing (WDM) network. As the transmitter and the receiver already use collimated optics, eliminating several lenses and fiber attachments with their associate alignment, as well as the physical enclosure, importantly reduces the price of the transceiver-ADM filter combination in comparison with the cost for a separate transceiver and ADM filter. Furthermore, the arrangement allows for a more flexible network growth.
