Altice Labs, S.A. Fiber Gateway 4x4
Operational Description 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 Wi-Fi (Dual Band). 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. 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. Data transmission is always initiated by software, which is the passed down through the MAC, through the digital and analog baseband, and finally to the RF chip. Several special packets are initiated by the MAC. These are the only ways the digital baseband portion will turn on the RF transmitter, which it then turns off at the end of the packet. Therefore, the transmitter will be ON only while one of the aforementioned packets is being transmitted. This device automatically discontinue transmission in case of either absence of information to transmit or operational failure.
