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.
The following figure 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 the 7210 SAS. 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.
To assist inventory management, the operator must use the configure>system>vwm-shelf vwm-shelf-
id vwm-type vwm-type create CLI command to configure the vwm-shelf-id of the clip-on device attached
to the 7210 SAS node. The vwm-shelf-id must match the shelf ID that is set on the rotary dial of the clip-
on device. 7210 SAS devices use the configured vwm-shelf-id to communicate with the clip-on device. If
the shelf IDs do not match, the 7210 SAS cannot communicate with the device and does not provide any
information about the device. The 7210 SAS cannot detect a mismatch between the configured vwm-shelf-
id and the shelf ID set on the rotary dial.
Depending on the type of supported interface, USB or OMC, the 7210 SAS node can manage only a fixed
number of 1830 VWM devices. The software prevents attempts to configure more 1830 VWM devices than
can be supported by the interface in use. Use the show command supported by the 7210 SAS devices to
display the shelf inventory and alarm status information provided by the clip-on device.
