FiberGateway

2.1 Summary
The FiberGateway is an Optical Terminal Equipment (ONT) unit for Passive Optical Networks (PON)
termination in a FTTH (Fiber-To-The-Home) service delivery architecture. FiberGateway communicates
with the OLT (Optical Line Terminal) for the PON side and with the customer’s premises for the client
side. This equipment supports triple-play services - high speed internet (HSI), voice (VoIP), video (IPTV)
and WPS (WI-FI Protected Setup). The use of the GPON fiber access technology does allow a
significant service delivery increase when compared with traditional xDSL technologies.
The FiberGateway equipment technology is based on GEM (GPON Encapsulation Method), and
complies with ITU-T G.984.x. recommendation as like as G.984.4 (OMCI) ensuring interoperability with
major GPON OLT vendors.
These base functionalities, together with the support for bit rates of up to 2.5 Gbps (downstream) and
1.24 Gbps (upstream), an optical network splitting ratio of up to 1:64 in a single fiber and a distance
range of up to 60 km, make the GPON technology and the FiberGateway the most efficient option for
passive optical network topologies, when integrated service delivery is an issue.
Together with multi-vendor OLT interoperability, other differentiated features of the FiberGateway
product include the use of an embedded optical reflective component that increases probing resolution
in case of FTTH probing. The FiberGateway is also one of the first single household integrated CPE
solution (ONT+GATEWAY).
As opposed to the point-to-point architecture, in which there is one physical port per client in the
Central Office, in GPON point-to-multipoint architecture there is only a single laser and photo-detector
in the Central Office (CO) to serve up to 128 CPEs. All the Optical Distribution Network is built by means
of passive equipment modules with a long live MTBF standards and very low OPEX
2.2 Technical Description
2.2.1 FiberGateway Main Functionalities
The FiberGateway is aimed for customer premises and complies with the ITU-T G.984.x
recommendation in order to transport (over GPON) and deliver (to premises domain) the full broadband
service pack.
Broadband service applications are commonly referred as below:
• High speed internet (HSI);
• Voice (VoIP) services (SIP/MEGACO H.248);
• TV (IPTV);
• WI-FI.
The multiplay environment is thus reinforced when combining the upper referred services.
