Optical fiber by the cold into products

FTTH (Fiber To The Home), just as its name implies is a piece of optical Fiber directly To The family. Specifically, it is to point to will FTTH optical network unit (ONU) installed in homes users or enterprise users place, in addition to the optical access series FTTD (optical fiber to the desktop) outside the most close to the light of the user access network application type. The significant technical characteristics FTTH is not only provide more bandwidth, and enhance the network to data format, rate, the wavelength and the transparency of the agreement, eased restrictions on environmental conditions and electricity supply requirements, simplified the maintenance and installation. Said to FTTH would first have to talk about optical fiber access. Optical fiber access is to point to the bureau between users and completely with fiber as transmission media. Optical fiber access can be divided into active optical access and passive optical access. The main technology of optical fiber user nets transmission technology is light waves. At present the reuse of the optical fiber transmission technology development quite quickly, the most practical is already in. According to the extent of the optical fiber deeply users, can be divided into FTTC, FTTZ, FTTO, FTTF, FTTH, etc.

Cold meet products in foreign countries in FTTH engineering extensively, and has been confirmed, king in place of stability, more convenient and reliable than welding. Cold meet products include optical fiber connectors and optical fiber cold in fast by the son of two products. And for optical fast in connectors, given the limitations of the cold by technology, almost all adopt the preset fiber technology, this kind of product operation is simple, but it was easy to produce false in docking, long-term stability of the product is of certain hidden trouble, at present the preset of optical fiber technology are all in the research into the stage of these conditions launched box build by laying bricks or stones optical fiber cold meet the son, from operation, performance, application range full beyond the similar foreign products.
