About to optical communication, simba rekutonga rinoratidza kuve rakakosha nzira kana zvasvika pakugadzikana pamwe nehunyanzvi hwezviratidzo munzvimbo yavanoda. Nekuwedzera kwekuda kwekumhanya uye kugona kwemanetiweki ekutaurirana, pane kudiwa chaiko kwekutonga simba remwenje masaini anofambiswa kuburikidza nefiber optics zvinobudirira. Izvi zvakakonzera kugadzirwa kwe fiber optic attenuators sechinhu chinodiwa chekushandisa mufibers. Ivo vane yakakosha application mukuita seattenuators nekudaro kudzivirira kusimba kwemasaini ekuona kuenda kumusoro zvichikonzera kukanganisa kumidziyo yekugamuchira kana kunyange yakamonyoroka masaini mapatani.
Fiber attenuation inova musimboti wekutanga mufiber optic link inogona kutsanangurwa sekurasikirwa kunoitwa pasimba rechiratidzo iro riri muchimiro chechiedza painopfuura nemu. fiber optic tambo. Uku kudzikisira kunogona kuitika nekuda kwezvikonzero zvakasiyana zvinosanganisira kuparadzira, kutora, uye kukotama kurasikirwa. Kunyangwe kudzikisira kwechiratidzo kwakaringana haifanire kusvika kune yakanyanyisa nhanho sezvo ichikuvadza kushanda kwe optical communication system. Kugadzirisa dambudziko iri, attenuators anoshandiswa mukudzidzira kudzikisa kusimba kwechiratidzo kusvika padanho rekushandisa kwayo kunoshanda uye kushomeka kwekuita kwehupenyu hwetiweki.
Mune an optical communication system, chiratidzo chinofanira kunge chiri cheimwe nhanho yesimba inodiwa neanogamuchira kugadzirisa chiratidzo. Kana chiratidzo chine simba rakawanda, saka inoremedza mugamuchiri uye dzimwe nguva inotungamira kune zvikanganiso, uye kana iyo chiratidzo ichitakura yakaderera simba, ipapo mugamuchiri anogona kusakwanisa kuona chiratidzo nenzira kwayo.Fiber optic attenuatorskuita basa repakati mukuchengetedza chiyero chakadaro kunyanya kana madaro ari mapfupi zvichikonzera kuwanda kwesimba repamusoro rinogona kuve ruzha pane inotambirwa.
Kune makirasi maviri efiber optic attenuators, imwe neimwe inosiyaniswa nekuvakwa kwayo uye basa: Fixed attenuators uye akasiyana attenuators. Fiber optic attenuators inowanikwa mumagadzirirwo akasiyana uye mhando, uye imwe neimwe yadzo yakakodzera kune chaiyo kushandiswa kana kudiwa. Fixed Attenuators vayevereri vepasirese nepo vanosiyana-siyana vari vatendi chaivo.
Fixed Attenuators: Aya maattenuators anopa mwero wakaenzana weattenuation uye anowanzo shandiswa mumamiriro ezvinhu, uko kunoenderana nhanho yekudzora inodiwa. Fixed attenuators anowanzo gadzirwa kune mamwe mazinga ekuyeredzera, akasiyana anogona kusiyana kubva akati wandei dB kusvika makumi edB. Mukana mukuru weaya marudzi emafayibha kureruka kwekushandisa pamwe nekuisa mune akasiyana akajairwa optical communication system.
Variable Attenuators: Kune rimwe divi, zvinosiyana-siyana zvinodzivirira zvinobvumira rusununguko rwekusiyanisa huwandu hwekudzikisira hunoshandiswa nekuda kwekusiyana kwayo mugadziriso weattenuator. Kugadziriswa uku kunogona kuve kwakazara nemanyorero kana kunogona kufambiswa nekushandiswa kwemagetsi ekutonga. Variable attenuators vanogona kushandiswa mukusiyana-siyana kwesimba masisitimu uko masaini anogona kuuya nesimba rakasiyana panguva dzakasiyana uye nekudaro uko simba rawo ringada kugadziridzwa nguva nenguva. Ivo vanogona kuwanikwa mune yakawanda bvunzo uye kuyerwa uko masaini anosiyana uye anosiyana.
Fiber optic attenuatormuchirevo chechinyorwa chino, zvisinei, zvinoreva chinhu chinowedzera chakagadzirwa nechinangwa chakaenzana chekurebesa chiedza kusvika pamwero wakafanorongwa. Mune mamwe mazwi, izvi zvinogona kuitwa kuburikidza nemaitiro akadai se adsorption, diffraction, uye kufungisisa. Vese vari vatatu vane zvazvakanakira uye vanosarudzwa zvichienderana nekutsanangurwa kwekushandisa kuri kuitwa.
Absorptive Attenuators: Aya attenuators anosanganisira zvinhu zvinonyatsonyura 'chikamu chechiratidzo chemaziso uye chinodzivirira kubva pakusimba zvakanyanya. Imwe yedzakakura dhizaini yekutarisisa kana uchigadzira attenuators zvichienderana neabsorptive inoshanda masisitimu isarudzo yechinhu uye chimiro kuitira kuti izvi zvipe iyo ingangoita yenguva dzose kudzoreredza pane inodiwa wavelength span pasina kuunza kurasikirwa kwakawedzera.
Kuparadzira Attenuators: Chiedza chekuparadzira-chakavakirwa vatendi vanoshanda pamusimboti wekuita nemaune kurasikirwa nenzira yekukanganiswa kwenzvimbo mufiber kuitira kuti chimwe chechiitiko chechiedza chirove pamadziro epakati uye chipararire kunze kwefiber. Nekuda kweizvozvo, iyi mhedzisiro yekuparadzira inotungamira kune kupera simba kwechiratidzo pasina kukanganisa kugona kwekuzvarwa kwefiber. Iyo dhizaini inofanirwa kuvimbisa kugovera uye inotarisirwa PUF mapatani kuitira kuti vawane iwo anodiwa attenuation mazinga.
Reflective Attenuators: Reflective attenuators vanoshanda pamusimboti wemhinduro, uko chikamu chechiratidzo chechiedza chinodzoserwa kumashure chakananga kunobva, zvichideredza kutapurirana kwechiratidzo munzira yekumberi. Aya attenuators anogona kusanganisira zvinoratidzira semagirazi mukati menzira yekuona kana kuiswa kwemagirazi munzira. Kurongeka kwehurongwa kunofanirwa kuitwa nenzira yekuti zvinoratidzira zvinokanganisa sisitimu nenzira yekuti chiratidzo chechiratidzo chinokanganisa.
Fiber optic attenuators zvinhu zvakakosha zvemazuva ano optical communication masisitimu, ayo vagadziri vanofanirwa kusarudza nekungwarira. Kuburikidza nekudzorwa kwezviratidzo zvesimba, aya magajeti anovimbisa yakachengeteka uye inoshanda kuyerera kwedata mukati metiweki. Mukupararira, fiber attenuation ndiko kudzikira kwechiratidzo kunoitika pamusoro pechinhambwe chakapihwa semhedzisiro yechiratidzo chechiratidzo, kupindira, uye kuparara. Kuti ugadzirise dambudziko iri, kune akasiyana marudzi eattenuators ayo mainjiniya angangofanira kuziva nekushandisa. Mukufambira mberi kwe tekinoroji yekukurukurirana tekinoroji, munhu haakwanise kufuratira kushanda kwefiber optic attenuators sezvo michina yekubaya nekugadzira icharamba yakakosha mukufambiswa kwemapuratifomu aya akaomarara.
