The optical network consists of an Optical Line Terminal (OLT) located at
the central office and Optical Network Terminals (ONTs) located at the
customer premises.
To allow for the transmission of downstream and upstream traffic on one
single fiber, different wavelengths are used for each direction.
Downstream traffic uses 1490 nm, while upstream traffic is carried on
1310 nm. For RF TV distribution, 1550 nm is used for downstream and
1610 nm is used for the upstream RF return path. The ONT uses optical
diplexers to separate the wavelengths.
This Job Aid covers the electronics module and housings listed in the
following table:
