Light TAP (demultiplexing scheme bare enlarge) spectral amplification equipment can not affect the original transmission link, the complete copy or multiple copies of data to downstream equipment, to ensure the stability and reliability of the data collected. With this series of splitters can solve most of the applications of data mirroring and acquisition, through OEO enlarge lower link can be resolved spectroscopic optical power down, and then lead to the back-end device receives data error occurs even receive data and other problems in the normal chain splitter spectroscopic when the optical signal intensity / power allocation according to the ratio of light corresponding to a plurality of link after spectroscopic, so the optical signal intensity after spectroscopic link / optical power will certain attenuation, and because the fiber and connector loss and dispersion itself, is likely to result in lower optical power down of the link, and then lead to the back-end device receives the data bit errors or receive data, phenomenon, splitting amplification equipment can perfectly solve this problem. TAP light branching optical amplifying apparatus can not only amplify the signal, there are the following greater functionality:? Amplifying an optical signal, while the distortion of the optical signal is shaped, and filter out the interference signal. ? Wavelength conversion. 1310nm to 1550nm wavelength can be achieved 1550nm to 1310nm wavelength or wavelength conversion. ? Combiner. Capable of more than 1310nm or 1550nm wavelength wavelength link together as a WDM wavelength transmission. Application Description: Operators generally proportional one point two splitters are mainly 5: 5,7: 3 and 8: 2, the proportion of one-third of the light the main points of 7: 1.5: 1.5 and 8: 1: 1; a division ratio of four light receptor is mainly 7: 1: 1: 1 25: 25: 25: 25, typically for a lower end of the spectral ratio of the light-relay needs to be added to ensure the normal rear end of the receiving device.
