Optical add drop multiplexer description
The passive CWDM optical add drop multiplexer (CWDM OADM) sends and receives signals to/from CWDM GBICs installed in the switch. It is set to a specific wavelength that matches the wavelength of the CWDM GBIC. It adds or drops this specific wavelength from the optical fiber and allows all other wavelengths to pass straight through. The Nortel Networks CWDM OADM supports two separate fiber pathways traveling in opposite directions (east and west) so that the network remains viable even if the fiber is broken at one point on the ring.
