Gigabit PON (GPON) An Introduction • A new solution has emerged into the optical access market place –GPON (Gigabit PON), offering unprecedented high bit rate support while enabling transport of multiple services, specifically data and TDM, in native formats and at an extremely high efficiency. The main requirements as mentioned in ITU documents can be summarized as follows: • Full Service Support – including voice (TDM, both SONET and SDH), Ethernet (10/100 BaseT), ATM, leased lines and more. • Physical reach of at least 20 km with a logical reach support within the protocol of 60 km. • Strong Operation Administration and Maintenance (OAM&P) capabilities offering end to end service management. • Security at the protocol level for downstream traffic due to the multicast nature of PON.
Technology Trends Based on the broadband drivers, PON technologies are becoming more and more appealing to service providers. They can support : • Convergence trend • Advanced applications • Virtually unlimited bandwidth demand • Required business models • Infrastructure competition.
FTTH - System Architecture • Alcatel’s Fiber to the User (FTTU) solutions allow operators to extend the core optical network all the way to the user, eliminating the bandwidth bottleneck in the last mile. • The solution support both residential and small business customers, offering unprecedented voice, video and data over a single fiber. • The Alcatel 7342 Intelligent Services Access Manager Fiber to the User (ISAM FTTU) is a fully standards-compliant Gigabit passive optical network (GPON) solution with twice as much throughput as other Passive optical network (PON) solutions.
System Architecture (Contd.) • Being highly scalable and flexible it provide service for more than 2,300 subscribers when configured to terminate 64 subscribers per PON facility. • Can transport ATM, Ethernet and IP protocols using GPON encapsulation method (GEM) .
FTTU Components • 7342 Packet Optical Line Termination (P-OLT) • 7342 GPON Single Family Unit Optical Network Termination (GSFU-A) • 5523 Access Management System (AWS) • 5528 Web Access Manager (WAM)
Packet Optical Line Termination (P-OLT) • The 7342 P-OLT is the core of the GPON system. • It provides capability to terminate multiple passive optical network terminations to ONTs and connect those for user and control plane traffic to the operator's network using Ethernet technology.
7342 GPON Single Family Unit Optical Network Termination (GSFU-A) • The 7342 Single Family Unit ONT (GSFU-A) provides the capability to deliver triple play services. • The GSFU-A unit provides: • 2 x 10/100 Base T Ethernet interface • 4 POTS lines for voice (VOIP) • IPTV support • H.248 for VOIP signaling
7342 ONT The GSFU-A dimensions are 342H x 303W x 109D (mm).
Services Support The 7342 are a triple play capable platform. It supports the following services: • Voice • High Speed Internet Data • IP video

Optical Loss Maximum average splice loss 0.05 dB (all splices in one link from ONT to OLT). Maximum individual splice loss is 0.15 dB. • 1x4 splitter loss - 7.5 dB • 1x8 splitter loss - 11.3 dB • OFC Per KM loss - 0.35 dB • Connector loss - 3 dB In a distance from 3 KM upto 10 KM, considering all components and joints like : 8 Splicing positions 1 1x4 Splitter 1 1x 8 splitter and 2 Connectors Total Optical Loss varies from 26 dB to 29 dB at 1310 nm
Next Generation Network (NGN) • Next Generation Network is a packet-based network to provide telecommunication services, makes use of technologies in which service-related multiple broadband QoS-enabled transport functions are independent from underlying transport-related technologies. • It supports generalised mobility which will allow consistent and ubiquitous provision of services to users. • Interworking with legacy networks via open interfaces • Converged services between Fixed/Mobile • Compliant with all regulatory requirements; for example concerning emergency communications, security, privacy, lawful interception.
TCIL’s Proposed Network Initial deployment proposal consisted of a full end to end turnkey project including: • Implementation of an IP/MPLS backbone data transport equipment. • NGN network composed of: • MGCF and AGCF functions for H248 call control providing a full set of Class 4 and Class 5 voice services • Trunking GWs for transparent connectivity between PSTN and IP • Media Server (MRF) for access to tones and announcement resources • Overall Centralized network management
The above figure depicts target solution in compliance with IMS/TISPAN. The solution provides a user centric Broadband services delivery environment having the flexibility to grow in both mobile and fixed services as well as cost effective migration of installed base.
