6. e 22kHz output from the satellite tuner cannot be transferred on the fiber between LB EO and LB OE because this signal goes the other way The LB OE can nevertheless detect voltage and or tone and put them to the GPI output on the LB OE Using a separate communication line two digital signals using D422MG or similar these signals can be transferred to the LB EO Another alternative is controlling the LB EO directly using either Gyda or GPI inputs The LB OE will always detect the voltage tone from the satellite tuner or other equipment and set the GPI according to the detected tone and voltage A 22 kHz tone on top of the LNB power supply indicates high band 11 7 12 75 GHz and no tone is for low band 10 7 11 7 GHz Vertical polarization is chosen with a voltage less than 15 volts typically 13 volts Most LNBs will set vertical polarization within a voltage window for instance from 11 5 to 14 2 volts dependant of the LNB Accordingly the horizontal polarisation is voltage greater than 15 volts typically 18 volts for instance from 15 8 to 19 0 volts If the voltage is near 15 for instance between 14 2 and 15 8 the polarization will be uncertain The example voltages are LNB manufacturer dependant please check the user manual for the LNB voltage thresholds 4 1 Mounting the connector module The details of how the connector module is mounted is found in the user manual for the sub rack frame FR 2RU 10 2 This manual is also avai

9. ital satellite signals is also important Many analogue satellite signals which tend to have higher power will reduce the signal to noise ratio on the digital signals This is because the link s power must be reduced according to the total power of the link Noise figure of the link is a number usually in dB that states how much the signal to noise ratio S N ratio is reduced from the input to the output If the S N ratio from the dish is X dB the noise figure on the link is Y dB the S N ratio on the output will be X Y dB Dependant on the application fiber loss total power on signal and power of the laser one link will typically add 4 5dB noise for fiber distances less than 3000 meters A coaxial cable will attenuate more on higher frequencies than lower If the attenuation on 2GHz is more than the noise figure for the L band link there will be a system nevion com 4 LB OE Rev E improvement regarding total signal to noise ratio Therefore to distance from the dish to the receiver must be significant more than 200 meters dependant of the coaxial cable specification for getting return of the investment of the L band link If the application needs galvanic isolation the L band link is a very good way to achieve this functionality nevion com 5 LB OE Rev E 2 Specifications 2 1 RF Characteristics Frequency band width 950 2150 MHz Return loss gt 10dB RF interface F connector Monitor interface BNC attenuated s
