The status of optical fiber access network
After recent years of research and practice, the first fiber optic cable to the curb (FTTC), Fiber to the Building (FTTB) is the consensus of telecom operators in the construction of access to fiber optic cable. The organization of the access cable is mainly used in the circular access trunk cable + star wiring cables, cable transfer equipment using a cable transfer box.With the popularization and promotion of the fiber, the fiber optic cable access in recent years demand for further growth:(1) fiber access number and proportion of large customers have greatly increased;(2) "light into the copper," the construction of the implementation of the strategy, resulting in the increase of the number of service access points;(3) a number of important customer requirements to protect the fiber optic cable on the wiring segments;(4) increased demand for FTTH constructionFiber access growth in demand, leading to greatly increase the building size and coverage of the fiber optic cable. Existing building patterns and the network organization has been unable to meet the needs of large-scale fiber optic cable construction, especially in big cities some of the fiber access user-intensive problems of the region is more prominent, the following problems:(1) access to the backbone fiber ring long construction period, can not meet the requirements of rapid deployment;(2) cable transfer box space is limited, is not conducive to expansion;(3) non-standard way optical switching box with fiber inside the cable fixing point and other resource consumption;
(4) a large number of customers wiring fiber optic cable to protect the existing ring cable structure in order to achieve the second route to increase the complexity of access to the backbone fiber optic cable used.

Classification and characteristics of the wiring cable access methods
There are three forms of fiber optic cable wiring, ring descending wiring method, star descending wiring method, star descending wiring method.A ring without decreasing curve fitting method.(1) ring connection routing decreasing curve fitting method.(2) for high-speed broadband services a wide range of needs, and rapidly growing urban and commercial areas.(3) using this curve fitting method, the transmission equipment shall constitute the ring core in loop without descending wiring, can be selected at any point in core, core accommodating high, may at any time to meet the requirements.(4) in a certain area was connected in a ring optical WAN (Wild Area Network) in this particular area it is easy to provide inter-building optical wiring network and realize the network branch is a high reliability wiring method.2 star descending wiring method(1) is basically a star wiring, but non-core decreasing form of wiring method.(2) applies subject to construction equipment, to ensure that the limited pipeline route using ring without diminishing the more difficult areas of the wiring method.(3) Wiring from the end office to remote users, decreasing core and ring descending curve fitting method, the core of the accommodation is very high, but also a immediately to meet demand wiring method.(4) fiber optic cable failure, you need the other fiber optic cable or other routing remedy, so a slightly lower reliability curve fitting method.3 star descending wiring method(1) consider the economic demand locations and cable connections to the core decreasing star descending curve fitting method.(2) applies to the demand dispersion in a wide range, and small changes, the user is more stability in the region.(3) each of the core dispersed users together for wiring, it is difficult to meet emergency needs, the core accommodation very poor.(4) does not predict accurately and frequently additional works, resulting in wasted investment.(5) fiber optic cable failure, and the star decreasing wiring method also is a less reliable method of wiring.

The status and role of the fiber access technology in the optical access network
Access network using optical fiber access technology known as optical access network. It is notonly in the telecommunications network, but also in the future of communication and informationnetwork with an extremely important position, plays a key role in future development. First, it isthe largest telecommunications network and communications network, and its construction costsaccounted for more than half of the total cost of the telecommunications network; Second, theoptical access network to directly face the majority of users and a variety of applications, itsquality of service and content directly affect the development of the network, in fact, most of their business simply by the access network without going through the core network can be completed; third, it is the completion of the most important part of the integrated services ofvoice, data, events, video and other BHP by the road. Therefore, it is the current information and communication in high-tech competition is most intense and fastest-growing part.
