Kuri optique ya fibre optique, umurimo wingenzi wa transceiver nukwagura intera yohereza imiyoboro, ishobora kugabanya inenge umugozi wumuyoboro udashobora kohereza intera ndende kurwego runaka, kandi ukazana ibyoroshye kubirometero byanyuma, ariko kubo ninde mushya kuri transceiver Amwe mumakosa akunze gukorwa nabantu, nko kutamenya gutandukanya ihererekanyabubasha no kwakira iherezo rya fibre optique.Ni ukubera iki fibre optique transcevers igabanijwemo imashini niyakira?Ese A / B iherezo rya fibre optique ihinduranya bisanzwe?

Impera yimpera ya fibre optique igomba kuba iherezo ryihererekanyabubasha (iherezo) nimpera yakira (b iherezo).Impamvu ituma transceiver igabanywa mu ihererekanyabubasha no kurangiza kwakirwa ni uko transceiver ikeneye kohereza ibimenyetso mu byerekezo byombi iyo ikoreshwa, mubisanzwe ari bibiri.Abantu benshi bakoresha imiyoboro ya fibre imwe ku isoko;Impera zombi za transibre imwe ya fibre ni A-iherezo na B-iherezo.Uburebure bwumurongo kuri izi mpande zombi buratandukanye.Uburebure bwumurongo wihererekanyabubasha ni bugufi kuruta ubwakira.Mubyukuri, dual-fibre transceiver ntabwo ifite A na B iherezo, kuko uburebure bwumurongo kumpande zombi burasa.Gusa iyo uhuza TX (kohereza) impera na RX (yakira) iherezo, fibre imwe, nkuko izina ribigaragaza, ni fibre optique, kandi abanyamwuga bamwe babyita transceiver imwe-imwe, bivuga kohereza no kwakira ibimenyetso ku mpande zombi kuri fibre optique, kubera ko muburyo bumwe Module optique ikoreshwa imbere muri fibre transibre imwe ifite uburebure bubiri bwumucyo wasohotse, mugihe fibre-fibre ihuzwa na fibre optique, hamwe na firime yimbere ya optique guhagarika bifite uburebure bumwe gusa.

Amashanyarazi ya fibre optique agabanijwemo uburyo bumwe bwa fibre optique ya fibre optique hamwe na fibre optique ya fibre optique ukurikije umubare wa fibre.Ubwoko bumwe bwa fibre transceiver yanduzwa binyuze muri fibre optique, bityo urumuri rwandujwe kandi rwakiriwe rwanduzwa binyuze mumurongo umwe wa fibre optique icyarimwe.Muri iki gihe, kugirango ugere ku itumanaho risanzwe, uburebure bwumucyo bubiri bugomba kuba Byakoreshejwe Kuri Gutandukanya.Kubwibyo, optique ya module yuburyo bumwe bumwe bwa fibre transceiver ifite uburebure bubiri bwumucyo, muri rusange 1310nm / 1550nm, naho intera ndende ni 1490nm / 1550nm.Muri ubu buryo, hazabaho itandukaniro hagati yimpande zombi zoguhuza guhuza ibice bibiri, kandi impera imwe ya transceiver izaba itandukanye.Kohereza 1310nm hanyuma wakire 1550nm.Indi mpera ni kohereza 1550nm no kwakira 1310nm.Biroroshye rero kubakoresha gutandukanya, kandi inyuguti zikoreshwa muri rusange.Noneho hariho iherezo (1310nm / 1550nm) na B-iherezo (1550nm / 1310nm).Abakoresha bagomba gukoresha ab couple.Aa cyangwa bb guhuza ntabwo byemewe.
