[background technology]

The cable TV signal transmission is exactly to utilize optical transmission to finish, and optical transmission is the technology of transmitting with the light signal form between transmit leg and recipient.The course of work of optical transmission TV signal is carried out between optical sender, optical fiber and optical receiver three.In the optical sender of central machine room, RF (electromagnetic frequency) TV signal of input is become light signal, it is finished by electricity/optical transducer, the optical signals Optical Fiber Transmission guiding receiving equipment that is varied to receives, and optical receiver is reduced into the signal of telecommunication to the converting optical signals that obtains from optical fiber.Therefore the principle of optical transmission signal is exactly the overall process of electricity/light and light/electric conversion, is also referred to as optical link.

The backlight transmitter module that known cable TV is independently exported in the four port light stations all is a RF (electromagnetic frequency) input, assembly is realized and being connected of light station owner plate by connector or cable, the back emitted thermomechanical components generally requires two in the light station, the client carries out operating when transmitter is different to be disposed comparatively complicated, and signal demand switching, reliability and stability can be affected, simultaneously because the design reasons of mainboard can cause some demand to realize, can not allow the user be provided with easily as required, and present assembly depends on light station owner plate, can not safeguard independently and upgrade, working method is single in addition, to the device upgrade trouble, can not satisfy customer personalized demand.

[summary of the invention]

The utility model provides a kind of standardized optical sender assembly that can constantly upgrade, respond user's different needs, can realize several working ways at above deficiency.

The technical solution of the utility model is: the light station back emitted thermomechanical components that the utility model is related, have shell and intraware, intraware comprises RF signal input interface, pcb board, driver module, it is characterized in that, described intraware comprises 3 RF signal input interfaces and one ten pin DC interface, a route plate interface is arranged on shell, and route plate interface is electrically connected with the output line road of enclosure, and this route plate interface is provided with the route plate of an activity.

Described route plate has an input and an output, and different route plate inside have different functional circuit module, and input is connected to radio frequency, and output is connected to laser diode;

Ten pin DC interface are used for linking to each other with light station loam cake PCB, and being connected of direct current supply and direct current signal is provided;

The RF signal input interface carries out the RF signal by cable and light station and is connected;

The route plate inserts from route plate interface, and can change flexibly, and is very convenient.

The beneficial effects of the utility model are: by three RF signal input interfaces and different route plates, realize multiple different working method, according to different network environments, the business model of implementing also is not quite similar, and the needs that continuous upgrading is arranged, this design can respond user's different needs well, and satisfies network upgrade needs in the future; Can allow simultaneously this product realize standardization, make production, stock, product maintenance convenient more, this design adopts cheaply that mode realizes multiple function, and has good operability, make user's upgrading and change deployment cost to drop to minimumly, make product have the use value of longer time.
