A component that connects several transmit or receive units.
A device that sends a very short pulse of light down a fiber optic communication system
and measures the time history of the pulse reflection to measure the fiber length, the light
loss and locate the fiber fault.
A channel that provides voice communication between operation engineers or
maintenance engineers of different stations.

See Optical Time Domain Reflectometer
See Optical transponder unit
A device or subsystem that converts the accessed client signals into the G.694.1/G.694.2-
compliant WDM wavelength.
The ranger of optical energy level of output signals.
Extra bits in a digital stream used to carry information besides traffic signals. Orderwire,
for example, would be considered overhead information.
Two slots of which the overheads can be passed through by using the bus on the
backplane.
The action of transmitting the same information that is being received for any given
direction of transmission.
A performance resource object defined in the network management system. The left end
of a path is a device node whose port needs to be specified and the right end of a path is
a certain IP address which can be configured by the user. By defining a path in the
network management system, a user can test the performance of a network path between
a device port and an IP address. The tested performance may be the path delay, packet
loss ratio or other aspects.
