  2. FTTC (Fibre To The Cabinet) • Fiber to the Cabinet (FTTC) is a telecommunication architecture based on fiber-optic cables run to a cabinet serving a neighborhood. Customers connect to this cabinet using traditional coaxial cable or twisted pair wiring. Why FTTC? • Low Cost • Non-blocking or low-blocking performance better supports convergence • Extremely flexible to deploy; supports Moves, Adds & Changes • Enables consolidation of electronics into a centralized Telecommunications Room • Allows the use of a variety of media from the Exchange to the user

  3. What is the FTTx? • Fiber to the x (FTTX) is a generic term for any network architecture that uses optical fiber to replace all or part of the usual copper local loop used for telecommunications. • The four technologies, in order of an increasingly longer fiber loop are: • Fiber to the node / neighborhood (FTTN) / Fiber to the cabinet (FTTC) • Fiber to the kerb (FTTK) • Fiber to the building (FTTB) /Fiber to the Premises (FTTP) • Fiber to the home (FTTH)

  5. FTTx Features and Benefits • Quicker installation and maintenance • Superior blowing performance • Greater design flexibility and consistently high performance levels • Easily absorbs new users and technologies • Compatible with a variety of mini-cables • Tube bundles available as single tube or multiple tube sizes for maximum flexibility • Light-weight, reduced-diameter mini-cables allow higher fibre counts in smallertubes • Lower day-1 costs for building the network

  6. FTTx Features Benefits Contd. • Tube bundles fully assembled in the factory, providing significant cost benefits • Only product to blow in is the fibre—no need to blow tubes into sub ducts • Fewer connection points • Shorter installation times and therefore reduced labour costs • Longitudinal water blocking allows cost-effective closures and simple clamping • Network can be developed in line with network and budget requirements • Reduced network modification and maintenance costs • Increased ability to reach new customers and generate revenue immediately

  7. FTTH (Fiber to the Home) • Fiber to the home (FTTH) is the ideal fiber-optics architecture. • In this architecture, fiber deployment is carried all the way to the customer's home (premises). • Fiber Optic service to the home is the fastest, most reliable and secure method and far surpasses anything that Broadband or "wireless" could ever even dream of. • Today’s vast cellular and wireless network runs and "communicates" via a fiber optic backbone. • This is the only way such vast amounts of data can be transported from caller to caller -quickly and securely.

  8. FTTH (How It Works) • In an FTTH system, equipment at the head end or CO is interfaced into the public switched telephone network (PSTN) using DS-1s and is connected to ATM or Ethernet interfaces. Video services enter the system from the cable television (CATV) head end or from satellite feed. • All of these signals are then combined onto a single fiber using WDM techniques and transmitted to the end user via a passive optical splitter. The splitter is typically placed approximately 30,000 feet from the central office (CO). The split ratio may range from 2 to 32 users and is done without using any active components in the network. The signal is then delivered another 3,000 feet to the home over a single fiber. An ideal FTTH system would have the ability to provide all of the services users are currently paying for, such as circuit-switched telephony, high-speed data, and broadcast video services. • At the home, the optical signal is converted into an electrical signal using an optical electrical converter (OEC). The OEC then splits the signal into the services required by the end user. Ideally, the OEC will have standard user interfaces so that special set-top boxes are not needed to provide service. These interfaces would include RJ11 jacks for telephony, RJ45 jacks to high-speed data, and 75 ohm coax ports for CATV and DBS service.

  9. The Future • The desire for two-way, video-based services such as interactive television, distance learning, motion picture-quality videoconferencing, and videophones is expected to continuously increase. • Some observers believe that there is already a worldwide demand for these futuristic services today. The capability to meet this demand and continuously add new services at mouse-click speed is creating enormous competitive pressures. • Such capability also offers tremendous revenue potential. Service providers who are able to offer these services to an ever-growing customer base can double or even triple their revenue in a short period of time. • As a result, demand for fiber technologies such as FTTH are on the rise. Technology advancements in the area of WDM are expected to further refine and enhance the technology, enabling more service providers to justify the investment in FTTH.
