3. About GPON
Gigabit Passive Optical Network with Gbps downstream and 1.244Gbps Upstream
Passive Optical Power splitters used to share a single fiber with 32/64/128 ONTs/ONU
Dominant technology for delivering last kms access over fiber
International Standards Based Protocol ITU-T G.984.x and G.988 specified protocol developed by FSAN (Full Service Access Network) and interoperability by Broadband Forum (BBF)
G-PON use has been extended beyond providing FTTx Broadband Access to applications such as 2G/3G/LTE/WiMAX Mobile Backhaul (MBH) and Fiber to the Desktop
G-PON Dual IPv4 and IPv6 Stack support defined in G.988

9. G-PON for Railway Sector Broadband Railway Line (BRL) Networks

10. Example – RailTel Corporation’s Backbone DWDM Network
RailTel Corporation of India Limited, a Government of India undertaking under the Ministry of Railways, has built a state of the art backbone network of SDH & DWDM:
600 Cities

40,000 RKM (Routed km)
Present DWDM Network using STM-16 (2.488Gbps) 10,500 RKM
31 Points-of-Presence (PoPs)
100G which can be augmented to 400/800G capacity
14,000 RKM planned in 2012 across additional 44 cities to cover whole of India
Network ready to deliver 10G

Railway Signaling Gates - e.g. Sensor networking using IPv4/6, CCTV
Railway Level Crossings - e.g. Sensor networking using IPv4/6, CCTV
Security and Safety – e.g. CCTV placement every 200 to 500m using Linear bus ODN topology
Freight Corridor Monitoring – e.g. Intelligent Sensor networking using IPv4/6 and a linear bus ODN topology
Rail Coach Factories – e.g. TLS connectivity to departments and factory floor
Railway Colonies – e.g. Triple-play residential services
Railway Hospitals – e.g. Tele-medicine and Tele-presence
Railway Schools– e.g. Long Distance Learning (LDL) and Tele-presence

16. BRL Network “Two-spoke” G-PON ODN Topology
OLT is the hub of the virtual wheel. The trunk/feeder fibre is indicated by the solid red lines, the spokes, of which the fibre spurs off to the Primary Fibre Concentration Point (FCP).
ONT/ONUs grouped in clusters consisting of one or more zones, with each zone containing the Secondary Fibre Concentration Point (FCP).
“Two-spoke” a good candidate for using Linear Bus Splitter topology

26. Conclusion

27. Conclusion
G-PON’s passive, built-in traffic aggregation, seamless integration into existing fibre plants, huge user capacity, service oriented FCAPS, Advanced Security support, High Availability options such a path protection, and flexible ODN topology such a linear add/drop bus, makes it a perfect match for building Optical Broadband Railway Line (BRL) Access Networks
As Railway’s deploy G-PON for the Access and Edge Aggregation portion of their Optical Fibre communication (OFC) networks, it is expected that as of yet un-envisioned Railway-specific new revenue generating services and applications will be realizable due to G-PON’s any-play service architecture.
