Yet, the online equipment of the terminal that has in optical fiber network system only is used for providing the function of filtering data, usually this Terminal Type is hardware firewall or router with traffic management function, when the online equipment of this Terminal Type is delayed machine or outage, because no longer providing data, it flows, can make the data between the optical fiber communication network between different local sides to transmit, just form broken string between fiber optic network, the solution for problems is not yet arranged at present.
The utility model content
For the defective of prior art, the utility model discloses a kind of optical signal transceiver device, fiber optic network still can keep UNICOM when running into terminal equipment when machine or power interruptions.
For achieving the above object, the utility model is achieved through the following technical solutions:
The optical signal transceiver device, comprise two-way light Transmit-Receive Unit, every road light Transmit-Receive Unit comprises a smooth transmitting element and a light receiving unit, described smooth transmitting element and light receiving unit are connected to photoelectric conversion unit, photoelectric conversion unit is electrically connected to electric signal transmission interfaces, wherein is connected with same diverter switch between two-way light Transmit-Receive Unit and photoelectric conversion unit.
Its operation principle is as follows: the light Transmit-Receive Unit is in order to receiving and dispatching light signal, and light signal is sent to photoelectric conversion unit, and photoelectric conversion unit is used for completing light signal to the conversion of the signal of telecommunication; Diverter switch is optionally to connect two-way light Transmit-Receive Unit.
When transceiver of the present utility model is used in the online equipment of terminal of fiber optic network, when delay machine or power interruptions of online equipment occurs, the light signal of changeable two groups of light Transmit-Receive Units transmitting-receiving transmits mutually, two of the online equipment connection of terminal local side optical network units just can be kept the transmission of light signal therewith, prevent that online equipment from causing the network system broken string because of the machine of delaying or power interruptions.
Wherein, diverter switch can manual switchover, also can adopt automatic switchover, and when using when automaticallying switch, described diverter switch is connected with controller, and controller is electrically connected to electric signal transmission interfaces.
Adopt said structure, diverter switch has two kinds of concrete implementations: a kind of is the light diverter switch of locking-type, has switching signal and triggers the pin position, triggers the pin position as control end with this switching signal; Another kind is the light diverter switch of non-locking-type, has detecting pin position, as control end.
In order to reduce the volume of product, improve integrated degree, described two-way light Transmit-Receive Unit, photoelectric conversion unit, electric signal transmission interfaces are positioned on same circuit board.
Optical signal transceiver device of the present utility model, normally following connectivity scenario during use: described smooth Transmit-Receive Unit is connected with the optical transceiver of local side fiber plant, and described electric signal transmission interfaces is connected to the online equipment of terminal.
By above-mentioned improvement, transceiver of the present utility model is arranged on the online equipment of terminal of fiber optic network, can prevent that online equipment from causing Internet Transmission to interrupt because working as the disconnection of machine or power supply.
