FTTH Optical Receiver yog dab tsi?
IbFTTH Optical Receiver, feem ntau hu ua Optical Node lossis ONU receiver module, yog ib qho khoom siv hauv FTTH tes hauj lwm uas demodulates downstream optical signals (feem ntau ntawm 1550 nm rau CATV thiab 1490 nm rau PON cov ntaub ntawv) rau hauv coaxial RF outputs rau TVs, teeb - saum lub thawv, thiab modems. Tsis zoo li ib txwm tooj liab-raws li tshuab, ibFTTH Optical Receiverleverages qis- poob ib zaug- hom fiber ntau (SMF) kom ua tiav qhov nrawm nrawm txog 10 Gbps, txhawb nqa peb npaug - cov kev pabcuam ua si (video, suab, ntaub ntawv).
FTTH Optical Receiverunits tau muab faib ua active (powered, nrog amplifiers) thiab passive (tsis muaj hwj chim, WDM{0}}raws li) hom. Cov qauv ua haujlwm tshwj xeeb ** Tsis Siv Neeg Gain Control (AGC)**¹ kom ruaj khov RF tso zis ntau ntau thoob plaws qhov sib txawv ntawm cov khoom siv kho qhov muag (-20 dBm rau +2 dBm raug), kom ntseeg tau tias 80-105 dBμV outputs. PassiveFTTH Optical Receivervariants, zoo li cov uas muaj WDM², multiplex PON (1310/1490 nm) thiab CATV (1550 nm) cov teeb liab tsis muaj kev nthuav dav, zoo tagnrho rau qis - fais fab kev teeb tsa hauv tsev. Ua thawjSab saum toj FTTH Optical Receiver manufacturers 2025suav nrog Terra, Fibconet, Softel, thiab Fullwell, tsim cov khoom siv raws li DOCSIS 3.1 thiab GPON/XGS-PON cov qauv.

FTTH Optical Receiver ua haujlwm li cas?
Kev ua haujlwm ntawm ibFTTH Optical Receiverpib nrog lub photodiode (piv txwv li, InGaAs PIN) kuaj pom lub teeb pom kev zoo los ntawm OLT⁵, hloov photons mus rau photocurrent ntawm cov nyhuv photoelectric. Qhov tam sim no tau nthuav dav los ntawm qhov qis- suab nrov transimpedance amplifier (TIA) ua raws GaAs thawb- rub theem, nrog AGC circuits xyuas cov tswv yim fais fab los kho qhov nce dynamically- tuav lub tiaj ± 0.75 dB hla 1 GHz.
