  1. 1. What is FTTH Fiber to the home (FTTH) is the delivery of a communications signal over optical fiber from the operator’s switching equipment all the way to a home or business, thereby replacing existing copper infrastructure such as telephone wires and coaxial cable. FTTH is a relatively new and fast growing method of providing vastly higher bandwidth to consumers and businesses, and thereby enabling more robust video, internet and voice services. Benefit of FTTH Compared with other access technology like xDSL, FTTH has below benefits: High Speed, FTTH access speed can reach 1000Mbps or 10Gbps, while xDSL is less than 100Mbps; Long Distance, for example, the common form of gigabit Ethernet (1Gbit/s) runs only to 300 ft (91 m). However, 1Gbit/s Ethernet over fiber can easily reach tens of miles; Future-Proof, the fiber data rate of the connection is usually limited by the terminal equipment rather than the fiber, permitting at least some speed improvements by equipment upgrades before the fiber itself must be upgraded. FTTH Technology GPON and P2P GPON and P2P are the mainstream technology used in FTTH deployment, below section describes basic concepts related to the fiber to the home (FTTH) solution from the user side to the network side on FTTH networking using PON and P2P upstream transmission, respectively. 1

  3. 3. User Side Concept Description Home Gateway (HGW or HG) A gateway device positioned for small office and home office (SOHO) users. It provides multiple service ports, such as POTS and LAN, wireless local area network (WLAN). The HGW supports routing and remote management and diagnosis. Access Side Concept Description PON A network that uses the point-to-multipoint (P2MP) network architecture. A PON network consists of an optical line terminal (OLT), an optical distribution network (ODN), and optical network units (ONUs). It uses optical fibers to transmit data, supports more users with less optical fibers, and provides high access rates. ODN A network that consists of optical fibers and passive optical components, such as one or more optical dividers. The ODN network provides highly reliable optical paths to connect ONUs to an OLT. Optical Line Terminal(OLT) An aggregation device located at a central office (CO), which terminates PON protocols, like Huawei OLT MA5600T/MA5603T/MA5608T. Optical Network Terminal(ONT) A user terminal that provides various ports for users. In PON networking, the PON board of an OLT communicates with an ONT through the intermediate ODN network. In point-to-point (P2P) networking, an OLT communicates with an ONT through a P2P Ethernet optical access board. 3
  4. 4. Split Ratio A ratio used for dividing a downstream optical signal into sub- signals in the PON system. A greater split ratio will result in a high optical power for signal transmission over the same physical distance. Network Side Concept Description IPTV head end A contents preparation platform in the IPTV system. It receives signals, converts media formats, and manages media materials. FTTx Fiber to the x (FTTX) is a generic term for any broadband network architecture using optical fiber to provide all or part of the local loop used for last mile telecommunications. The term is a generalization for several configurations of fiber deployment, ranging from FTTN (fiber to the neighborhood/node) to FTTD (fiber to the desktop). FTTP Fiber-to-the-premises, this term is used either as a blanket term for both FTTH and FTTB, or where the fiber network includes both homes and small businesses. FTTB Fiber-to-the-building, -business, or -basement, fiber reaches the boundary of the building, such as the basement in a multi-dwelling unit, with the final connection to the individual living space being made via alternative means, similar to the curb or pole technologies. FTTN 4
  5. 5. Fiber-to-the-node, -neighborhood, fiber is terminated in a street cabinet, possibly miles away from the customer premises, with the final connections being copper. FTTN is often an interim step toward full FTTH and is typically used to deliver 'advanced' triple-play telecommunications services. FTTC Fiber-to-the-curb/kerb, -closet, or -cabinet, this is very similar to FTTN, but the street cabinet or pole is closer to the user's premises, typically within 1,000 feet (300 m), within range for high-bandwidth copper technologies such as wired ethernet or IEEE 1901 power line networking and wireless Wi-Fi technology. FTTD Fiber-to-the-desktop, fiber connection is installed from the main computer room to a terminal or fiber media converter near the user's desk.
