Abstract
The utility model discloses an optical fiber transceiver, which comprises an optical module, an Ethernet exchange chip respectively supporting an optical fiber interface and an electrical interface and an isolated electric Ethernet interface, and is characterized in that a USB power supply interface and a power supply adaptive chip are further inclused, wherein the USB power supply interface provides plus 5V power supply which generates 3.3V and 2.5V power supply through the power supply adaptive chip to be respectively provided for the optical module, the exchange chip and the electric Ethernet interface. By adopting the optical fiber transceiver provided by the utility model, the debugging and the configuration of an optical fiber Ethernet can be performed by only using a high-power USB interface of a computer or notebook PC under the condition of inconvenient power supply access. Under the situation that the optical fiber Ethernet is widely applied to the current smart grids and digitized transformer stations, the optical fiber transceiver can serve as a safe and convenient debugging tool since power station secondary power source is not allowed to be accessed arbitrarily in the field of power station.

The fiber optic Ethernet widespread is in industrial circle, comprise factory, power plant, power station, communication base station etc., at power domain, construction along with intelligent grid, the construction of intelligent substation, digital transformer substation and relevant smart machine, fiber optic Ethernet extensively applies to current digitlization, intelligent field as a kind of communication standard standard.In the industry spot debug process of fiber optic Ethernet, generally adopt fiber optical transceiver connection device optical fiber interface and debugging to monitor the electric Ethernet interface of using computer, the debugging of being correlated with test.Power based on the general mode of the forceful electric power power supply of external 220V interchange or direct current that adopts of optic fiber converter that use in current market, in industry spot, especially want power supply in the docking station in the debugging of power station, access at some occasion power supplys may cause inconvenience, in addition, arbitrarily insert power supply and also can produce hidden danger the safe operation at scene.Based on the inconvenience of eliminating this utilization, and guarantee on-the-spot security consideration, need to simplify the access scheme of fiber optical transceiver power supply.
The utility model content
The utility model patent technical problem to be solved provides and a kind ofly only provides the fiber optical transceiver that power supply can work by standard USB interface, can't be separately when settlement computer connects fiber optical transceiver provides utilization under the external 220V forceful electric power power supply situation for fiber optical transceiver.
For solving USB power supply technique problem, a kind of fiber optical transceiver that the utility model provides, comprise optical module, support the exchange chip of the Ethernet of optical fiber interface and electrical interface, the electric Ethernet interface that band is isolated respectively, it is characterized in that: also comprise USB power supply interface and power adaptation chip, the USB power supply interface provides+power supply of 5V, and+5V power supply is supplied with optical module, exchange chip and electric Ethernet interface respectively by the power supply that the power adaptation chip produces 3.3V and 2.5V.
Aforesaid fiber optical transceiver is characterized in that: compatible MINI USB interface of described USB power supply interface and Type B USB interface.
USB interface power supply ethernet optical fiber transceiver of the present utility model is a kind of ethernet ieee 802.3 media converters that adopted the power supply power supply of standard USB interface, can realize 10/100Base-T twisted-pair feeder and 10/100Base-FX or 10,100Base-T twisted-pair feeder and 10, medium conversion between two kinds of media of 100Base-FX or extension Network Transmission distance, support 10/100M or 10M fully, the transmission rate of 100M, the transmission that light mouth and electricity mouth can work under 10M or the 100M speed is used.
The beneficial effect that the utility model reached:
The utility model is different from the general optical fiber transceiver and is that its electric power system has adopted the weakness power supply of USB standard interface through design.Can be implemented in and be inconvenient to insert under the state of forceful electric power power supply, only use the high-power USB interface of computer or notebook computer, can carry out the debugging and the configuration of fiber optic Ethernet.In current intelligent grid, digital transformer substation, be extensive use of under the fiber optic Ethernet situation, do not allow arbitrarily to insert in the field, power station under the situation of power station secondary power supply and can use the debugging acid of this equipment as safe and convenient.
