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.
