The Total Access
®
351& 352 Single Family Unit (SFU) Optical
Network Terminations (ONTs) are Gigabit Passive Optical Network
(GPON) ONTs. The 351 SFU ONT has 2 POTS, and 1 Gigabit
Ethernet interface. The Total Access 352 has 2 POTS, and 2
Gigabit Ethernet interfaces. 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.
