SONET
Synchronous Optical NETwork. Standard protocol that defines a group of
fiber-optic transmission rates that can transmit various bit-rate signals inside a
broadband synchronous signal. SONET was designed to allow for a
multi-vendor environment.
SNR
Signal-to-Noise Ratio. The SNR measures the quality of the intended signal
versus any background noise. Usually expressed in decibels (dB).
SQM

staging
Installation phase during which equipment might be integrated and made
ready for deployment.
switch
A network device that selects the path for sending traffic to its next
destination.
Synchronous Optical NETwork
See SONET.
system gain
The ratio of transmit power to receiver sensitivity, usually expressed in dB.
This ratio usually does not include antenna gain.
