Abstract
The optical relay of a total optical network 650nm information transmission system relates to user terminal devices of optical networks composed of a supply conversion circuit, a fiber module supply process circuit, fiber module IP1 and fiber module IP2, in which, the supply conversion circuit converts 220AC voltage to +5V DC voltage circuit, the fiber module supply process circuit is connected on the +5V DC output circuit, IP1 and IP2 are connected to the output end of the fiber module supply process circuit and the input and output of IP1 are connected with the output and input of IP2, when a quartz fiber signal is converted into plastic fiber signal, the plastic fiber network has been connected with the quartz fiber network on the trunk and light is relayed by this invention to the terminal users with over 50m transmission distances and the plastic fiber system and public information network can be mutually communicated.
Description
Technical field
The present invention relates to a kind of network equipment, especially a kind of subscriber terminal equipment of optical-fiber network, " last kilometer " subscriber terminal equipment that just is commonly called as usually.
Background technology
The silica fiber network information on the existing backbone must be through light/electricity, electricity/light conversion when access user terminal, and this changing turns over journey and not only influence transmission speed, and causes signal attenuation, information distortion, is subject to external interference, and the information that also is prone to is stolen.
In order to change the above-mentioned defective in the existing information transmission, a kind of all-optical network just under study for action, all-optical network becomes the first-selection of (ultrahigh speed) broadband network at a high speed of future generation with its good transparency, wavelength routing characteristic, compatibility and extensibility.In order to reach at user terminal, be that last kilometer is still with optical transmission information, must convert existing 1550nm, 1310nm, 850nm silica fiber signal to 650nm plastic fiber signal respectively, could further be transformed into user terminal then, because the different positions of user terminal, signal produces decay in transmission course, continues because of the oversize needs of distance carry out 650nm light in plastic fiber system integration all-optical network, do not have optical relay, just can not finish the UNICOM of full light network diagram.
