Izihlanganisi Optical: injongo, iintlobo, iimpawu ze izihlanganisi

Ukuza kuthi ga ngoku, liphuhlise iintlobo ezingaphezu kwe-70 izihlanganisi ngeenjongo ezahlukeneyo kumgca fibre-optic le. Eyona eqhelekileyo - izihlanganisi twatsa optic ukuba abe ngumfuziselo uhlobo plug. Loqhakamshelwano izihlanganisi ezifana sebenzisa amaqhoshana ezikhethekileyo optic. Ngezi zixhobo le izihlanganisi lokukhwela woqondo isenokuba iintlobo enye okanye eziliqela.

Inkcazelo design isinxibelelanisi optical

izihlanganisi Pluggable enombala ngolu hlobo lulandelayo: i-ifayibha busisigxina kwi ngendlela ekhethekileyo udidi kwincam "ferrule", nto leyo lifakwa faka-egxile. Izinto zokubopha izihlanganisi kwi zombini isenokuba uhlobo okanye yangaphakathi onencula okanye lock. Kwezinye iintlobo zezixhobo iyafuneka ukudibanisa ngababini kabini Imisonto optic, ingakumbi ngenxa izihlanganisi optic uhlobo kabini kuye kwakhiwa. Ekuqaleni, ukuphunyezwa izixhobo ezifana kuyafikelelwa ngenxa ikliphu zeplastiki macala equka socket apho olungisiweyo iperi izihlanganisi, emva kokuba fixed Kwasika esiswini. Kakhulu le njongo izihlanganisi kunye nezakhiwo square. Noko ke, ekuhambeni kwexesha kwaba yimfuneko ke kwanokuba kuqulunqwe izihlanganisi kabini ifayibha okufana ne iphakheji enye.

Inqanaba elilandelayo yophuhliso ngokuveliswa izihlanganisi fibre optic iye yaba nokudalwa ezizodwa uhlobo izihlanganisi bhanti liphela buffer ukutyabeka. Namhlanje, nangona kunjalo, olu hlobo ayikho ethandwa kakhulu ngenxa ubunzima yokufumana ingenamthungo ezikumgangatho ophezulu, nkqu kunye nokusetyenziswa indlela yokwenza iwelding. Okwangoku, kubathengi eziphambili izihlanganisi zichazwayo Japan kunye United States.

ukucaciswa basic

Ipharamitha eziphambili izihlanganisi optic bandwidth, uzinzo lwexesha elide kunye nokumelana neemeko yangaphandle. Bandwidth luchaphazela umva vangama kunye nokulahlekelwa yokufaka umfanekiso. Ezi mpawu zixhomekeke ukubana ezinqamlezayo ye nezamazembe kunye engile ephakathi kwabo. Kukhutshwe uphawu ukusuka nokuvakalisa Fresnel kwi umda eyahlula eendaba ezimbini. Ixabiso ilahleko eliphezulu, apho kungene isinxibelelanisi na eziphango optical. Olu phawu kuchaphazela isixa ilahleko iyonke phecana. Le parameter kuxhomekeke ecaleni osecaleni (ukungalungelelani) umphakathi enxulumene imicu optic.

I parameter ebalulekileyo elandelayo - ngumfanekiso umva. Umthombo iphambili nefuthe lolu laka, - umda ukwahlukana phakathi eendaba amabini (umoya kunye nomsonto). Eli candelo unako ukufikelela amanani abalulekile. Ngaphezu koko, lo umva-vangama kunokuba ziyatshintsheka kwi kwexesha, oko kukuthi, phantsi kwempembelelo yeemeko lwangaphandle ekugqibeleni bakwazi ukwahlukana kwindlela yakho yonke.

audio optical

Ke kaloku iqashiso baduma kwi iinkqubo isixhobo yomsindo ningazuza iintambo ezinesigqubuthelo seplastiki. Inzuzo ephambili yezi micwe kukunqongophala ingxolo, kwaye ke ngoko, uphawu uya kuhlala ecacileyo kwaye upholile, nangona ubude ukwandiswa. Ifayibha optic zingqineke ngokwabo yokusebenza ethembeke imeko umoya, apho iingcingo zekopolo abazange bakwazi ukumelana ingxolo. Ithekhnoloji computer ezithandwa kakhulu cable SPDIF (Sony-Philips Digital Interface) - i-interface yokudlulisela Imiqondiso ezirekhodiweyo ifomu yedijithali. It nokudluliswa Imiqondiso audio phakathi izixhobo ngaphandle ilahleko esemgangathweni ekugqibeleni kwenzeka xa indlela analog.
