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.
Figure 3 shows the single wavelength CWDM OADM network and equipment
side connections.
