户外接收器

outdoor receiver ZGD-R750/860 Field Optical Receiving is economical, high performed equipment which it is capable to receive and distribute the forward signal and transmitter the feedback signal.The materials used the anti-water albuminous case which is the most advanced in the world. In the other hand, for the inside circuit, after the digital analog convertering the low noise would be amplify which still grantee the CNR standard when receiving power very low. In order to keep the non-linear standard stable and proportional increase of the power,we place the LED on the panel to display the receiving power of the obverse optical fiber. link parameters forwardreceivingoppositetransmittingCNR(dB)>51CNR(db)>51CSO(dB)<-65CNR(db)>51CTB(dBc)<-65CNR(db)>51 optical parameters forwardreceiveOppositeTransmittingopticallength(nm)1100 1600Opticalwavelength(nm)1310±10inputopticalpowerrange(dBm)-9 +2Transmittingoptcalpower(mw)1-4mWOpticaltie-inmodelFC/APCOpticaltie-inmodelFC/APCOpticalreturnloss(dB)≥45Opticalreturnloss(dB)≥45 RFI parameters itemforwardoppositefrequencyband(MHz)47/87 75047/87860530/65Flatnessinband(dB)±0.75±1RFIimpedance(Ω)7575Returnloss(dB)≥16≥16Middleattenuation(dB)caninsertcaninsertMiddleslope(dB)caninsertcaninsertPortoutput104dBμVOutput>85dBμVinput other parameters PowerVoltageAC180V 250V/AC60VPowerConsumption<50WOperatingTemperature-10 50StorageTemprerature-20 65size260W*230D*160H(mm)weight2.5kg
