the audio frequencies and below the infrared frequencies, used in radio transmission systems.
RMA
return material authorization. A form used to return products.
RT
remote terminal. Remote equipment of a supervisory system.

S
SBS
stimulated Brillouin scattering. The easiest fiber nonlinearity to trigger. When a powerful
light wave travels through a fiber, it interacts with acoustical vibration modes in the glass.
This causes a scattering mechanism to be formed that reflects some of the light back to the
source.
SMC
status monitoring and control. The process by which the operation, configuration, and
performance of individual elements in a network or system are monitored and controlled
from a central location.
SNMP
Simple Network Management Protocol. A protocol that governs network management and
the monitoring of network devices and their functions.
T
TEC
thermoelectric cooler. A device used to dissipate heat in electronic assemblies.
torque

(Newton-meters). The application of one pound of force on a lever at a point on the lever that
is one foot from the pivot point would produce 1 lb-ft of torque.
TX
