351 2 POTS/1 Ethernet Single Family
Unit (SFU) Optical Network Terminations (ONT) is a Gigabit
Passive Optical Network (GPON) ONT. The 351 SFU ONT
has 2 POTS, and 1 Gigabit Ethernet interface. The figure
above illustrates the
SFU ONT
inner enclosure. GPON
technology provides a consistent and common approach to
advancing the public communications network using:
•
Traditional telephone service is Plain Old Telephone Service
(POTS)
•
High speed data services
•
Video services
The GPON network consists of an Optical Line Terminal (OLT)
located at the central office and Optical Network Terminals
(ONTs) located at the customer’s premises. Between them lies the
Optical Distribution Network (ODN) consisting of fibers and
passive splitters or couplers.
In order 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.
The ONT employs
optical diplexers to separate the wavelengths.
