Key2 Optics Passive CWDM OADM/ROADM (Wiki: What is OADM/ROADM stand for?) is based on thin-film filter (TFF) technology and operates on a 20nm channel spacing ITU grid, with a CWDM wavelength range from 1270nm to 1610nm for CWDM transport network.
OADM is an important part of WDM network, which will dynamically reconfigure optical wavelength channels. That is, adjust the wavelength resource and fiber path in optical path layer, whenever the change of traffic and new demands from the transmission network is requested. OADM makes the most effective use of network resources.
