ADSL фильтр

Function: Adsl splitter/filter can eliminate the interference between data signal and voice signal transmitted in the same telephone line and make the internet and telephone go both at the same time(Data signal for internet voice signal for telephone) The structure of Adsl splitter/filter: One RJ11 at one end for line. a telephone line at other endSpecification:POST PORT IMPEDANCEZr=600 ΩModem impedance30 kHz to 2208 KHz100 ΩInsertion loss@ 1004 Hz<0.3dBWith 5 filters200 to 3.4 kHz< 2.5 dB3.4 kHz to 4 kHz< 4 dBAttenuation distortion between 600 ohms resistive single filter(relative to 1004 Hz)200 Hz<f<3.4 kHz<0.3dB3.4 kHz to 4 kHz<0.75dBReturn loss(LINE to PHONE)SRL-L>=12dBERL>=10dBSRLH>=5dBReturn loss(PHONE to LINE)SRL-L>=13dBERL>=9dBSRLH>=3dBLongitudinal conversion loss LCL200 Hz to 1 kHz> 58 dB1 kHz to 3 kHz>53 dBDC resistance<12 ΩDelay distortion200Hz to 4 kHz<100 u secIsolation resistanceTip to Ring>10MΩStop band attenuation30 kHz<f<300 kHz>26 dB 300 kHz<f<2208 KHz>65dB inner picture: Outer package:
