Description
The utility model relates to a kind of photoelectric technology, particularly a kind of Transmission Multiplexer in opposite directions of transmitting two channels with simple optical fiber.
Prior art must need two optical fiber as transfer medium when using same wavelength transmission to receive and sending out two groups of signals.When carrying out transmitted in both directions with simple optical fiber, must adopt two cover light end equipment of two wavelength, the general employing is dual wavelength wavelength division multiplexer technology (WDM), it need utilize the light source of two wavelength (1550/1310nm), transmit by two complete equipments, the cost of its transmission system is higher, and system complex inconvenience safeguards that the manufacturing cost of (WDM) wavelength division multiplexer is also expensive simultaneously.Above-mentioned dual mode all will cause the waste of resource and increase the complicacy of system.
The purpose of this utility model is to overcome defective of the prior art, a kind of two channel single fiber transmitted in both directions multiplexers are provided, so that the equipment of two optical ports is converted to an optical port very simply, in an optical fiber, transmits receipts in opposite directions and send out two light signals with same wavelength.
To achieve these goals, the utility model adopts following technology art scheme: comprising shell, settle opto-electronic conversion mechanism in the enclosure, and in a kind of two channel single fiber transmitted in both directions multiplexers of being constituted of electrical signal ports and light signal port, one end I/O arm of the optical directional coupler that will be coupled to form at the drop-down awl of molten condition by two optical fiber is connected with light signal emission port and light signal receiving port respectively, other end coupling arm then is a multiplexing port, joins with the joints of optical fibre.
Owing to adopted technique scheme, made to the utlity model has following significantly technique effect:
The utility model can transmit two groups of signals of sending and receiving of same wavelength in an optical fiber media, improved the utilization factor (1 times) of fiber optic network transmission, thereby reduced system cost.Existing pair of optical port receiving and sending equipment is converted to the monochromatic light port, transmits in an optical fiber, two perhaps that the equipment of two ends transmitted in both directions is used optical fiber are converted to the single fiber transmission.The added losses of its each input port can obtain different added losses values according to system design or demands of applications, and scope is between 1.5-6.0dB.The light isolation big (＞60dB), stable performance.Simple in structure, easy to use, with low cost.
The utility model will be further described below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the utility model dual wavelength optical directional coupler structural representation;
Fig. 2 is the utility model contour structures synoptic diagram.
With reference to accompanying drawing, the utility model comprises shell 1, settles opto-electronic conversion mechanism in the enclosure, and electrical signal ports 2 and light signal port 3.Be coupled to form an optical directional coupler 4 by two optical fiber at the drop-down awl of molten condition, one end I/O arm is connected with light signal emission port 5 and light signal receiving port 6 respectively, other end coupling arm then is a multiplexing port 7, with the joints of optical fibre is that light signal port 3 is connected, thereby has reached two properties that light signal transmits in opposite directions.
Multiplexing port 7 of the present utility model must be connected with the sloping optical fiber connector, makes the utility model steady operation to reduce reflection.
The utility model is a kind of Passive Optical Components.With character that is transmitted light signal and protocol-independent.Thereby support the communication protocol of nearly all web-transporting device, the scope of application is very wide.The transmitted in both directions of Ethernet for example.
