FTTB and

Ethernet
Cascade
Networking
(ONU works
as an
independent
NE)
l ONUs are deployed in
corridors or fiber
distribution terminals
(FDTs) on the curb. They
connected to users
through twisted pairs.
l The networking between
the ONU and users is the
same as the xDSL
networking for a PON
network. The networking
applies in the following
scenarios:
– FTTB and FTTC
networking in xDSL
access mode, without a
home gateway (HGW)
– FTTB/FTTC+HGW
networking (The voice
service is provided
through the ONU.)
– FTTB/FTTC+HGW
networking (The voice
service is provided
through the HGW.)

(ONU works

extended
subrack)
l Extended subracks are
deployed in corridors or
FDTs on the curb. They
connected to users
through twisted pairs.
l The networking applies to
high-bandwidth access
scenarios and provides the
high-speed Internet
access service, voice
service, and IPTV service.
In the scenarios, an HGW
is configured on the user
side and VDSL2 is used
for downstream
transmission.
