6.6.1 Introduction
The 1830 VWM device can be used in point-to-point or ring deployments to multiplex
multiple CWDM/DWDM channels over a single fiber. Either the existing fiber is
reused or a single fiber is used to meet the increasing demand for service bandwidth.
Up to 8 fixed CWDM channels are multiplexed over a single fiber using this unit.
Figure 32 shows 5 CWDM channels that are multiplexed over a single fiber.

There are two types of ring locations. One is a channel termination location, with the
1830 PSS-32 that optically terminates all the channels using either the 4-channel or
the 8-channel termination module. The second location is the intermediate OADM
sites with 7210 SAS-M. These sites use the CWDM passive units to add or drop a
channel in both directions (east and west), for the node to process traffic.
Additionally, these sites provide express lanes for all other channels (that is, those
not processed locally by the node). The 1830 VWM provides an option to add or drop
up to 1, 2, 4 channels of fixed wavelength for local processing by the node.
6.6.2 Feature Description
The 1830 VWM clip-on device can be connected to the 7210 SAS node (the master
shelf) using the USB interface or the OMC interface, depending on the interface
supported by the 7210 SAS platform. Each of these clip-on devices is identified using
the shelf ID, which is set on the rotary dial provided on the device.
