    description
      "This module defines configuration and operational state data
for transceivers (i.e., pluggable optics).  The module should be
used in conjunction with the platform model where other
physical entity data are represented.

In the platform model, a component of type=TRANSCEIVER is
expected to be a subcomponent of a PORT component.  This
module defines a concrete schema for the associated data for
components with type=TRANSCEIVER.

A transceiver will always contain physical-channel(s), however
when a line side optical-channel is present (i.e. ZR+ optics)
the physical-channel will reference its optical-channel.
In this case, the optical-channels components must be
subcomponents of the transceiver. The relationship between the
physical-channel and the optical-channel allows for multiple
optical-channels to be associated with a transceiver in addition
to ensuring certain leaves (i.e. output-power) are not duplicated
in multiple components.

If a transceiver contains a digital signal processor (DSP), such
as with ZR+ optics, the modeling will utilize hierarchical
components as follows:
PORT --> TRANSCEIVER --> OPTICAL_CHANNEL(s)
The signal will then traverse through a series of
terminal-device/logical-channels as required. The first
logical-channel connected to the OPTICAL_CHANNEL will utilize the
assignment/optical-channel leaf to create the relationship. At the
conclusion of the series of logical-channels, the logical-channel
will be associated to its host / client side based on:
* If the TRANSCEIVER is directly within a router or switch, then
 it will use the logical-channel ingress leaf to specify the
 interface it is associated with.
* If the TRANSCEIVER is within a dedicated terminal (Layer 1)
 device, then it will use the logical-channel ingress leaf to
 specify a physical-channel within a TRANSCEIVER component
 (i.e. gray optic) that it is associated with.";
