Hunhu hweEDFA Optical amplifier
Kureba kwekushanda kweEDFAChinopa simba reOpticalinowira mukati chaimo mehurefu hwewavelength hwe1330-1600nm hwekutaurirana nefiber optic. EDFA Optical Amplifier inoshanda muC-band (1530-1565nm) ine hwindo rekurasikirwa nefiber rakaderera yakashandiswa zvakanyanya. Kuti vashandise zvizere bandwidth resources ye optical fibers, vanhu vakazvipirawo kugadzira EDFA Optical Amplifier muL-band (1570-1610nm). L-band iri pamuswe weEDFA amplifier gain spectrum, saka L-band EDFA Optical Amplifier inofanira kushandisa fibers refu uye simba repombi rakakwirira, kana kushandisa fibers dzakanyanya kudhakwa.
EDFA Optical Amplifier ine gain yakakwira (inopfuura 30-50dB) uye inopa gain yakatwasuka pamusoro peband yakafara (kusvika 30nm), zvichiita kuti ikodzere kuwedzera masaini mumatanho akawanda e optical, kunyanya mumasisitimu e dense wavelength division multiplexing (DWDM). Ruzha rwakaderera (4-8dB), rwunosvika pamuganho we quantum. Kana ikashandiswa kumasisitimu eWDM, crosstalk pakati pemachannels inoderedzwa uye ma amplifiers akawanda anogona kuderedzwa. Iine simba re saturation output rakawanda (10-20 dBm), inogona kushandiswa se power amplifier mushure me transmitter kuwedzera daro re transmission kana kugoverwa kwenhamba yema optical nodes asina relay lines. Simba repombi rinodiwa rakaderera (makumi ema milliwatts). Gain yacho haina chekuita ne polarization state ye fiber, saka ine kugadzikana kwakanaka. Zviri nyore kubatanidza nema transmission optical fibers, nekurasikirwa kwakaderera kwe coupling (<1dB). Kunze kwepombi source,EDFA amplifierinoumbwa nezvinhu zvisingashande. Saka, kana tichienzanisa nemaelectronic regenerative relays akaomarara uye anodhura, mutengo wesystem unodzikiswa zvakanyanya uye kuvimbika kunovandudzwa. Pamusoro pezvo, hunhu hwekuwedzera kweEDFA Amplifier hahuna chekuita ne bit rate yesystem uye fomati yedata, saka inogona kuwedzera nekutumira ruzivo rwedhijitari nerwe analog.
Zvakaipa zveEDFA Optical Amplifier ndeizvi: saizi yakakura; Nguva yehupenyu hwepombi haisi refu; Haigone kubatanidzwa nezvimwe zvishandiso, izvo zvinoderedza kushandiswa kweEDFA Amplifier mukubatanidzwa kwe optoelectronic (OEIC). Pamusoro pezvo, bandwidth yegain yeEDFA Optical Amplifier inongovhara chikamu chewindo rekurasikirwa rakaderera re quartz single-mode fiber, izvo zvinoderedza huwandu hwenzira dze wavelength dzinogona kugara ne fiber, inovawo kushaya kwayo.
