Summary
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 (BBF.247).
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 (BBF.247 certified), 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.
