Optical transceiver nibikoresho byanyuma byo kohereza ibimenyetso bya optique.

1. Ubwoko bwa transceiver optique:
Optical transceiver nigikoresho gihindura E1 nyinshi (igipimo cyo kohereza amakuru kumirongo yimigozi, mubisanzwe ku gipimo cya 2.048Mbps, iki gipimo gikoreshwa mubushinwa nu Burayi) mubimenyetso bya optique kandi ikohereza (imikorere yacyo nyamukuru ni ukumenya amashanyarazi- optique).no guhindura urumuri-amashanyarazi).Amashanyarazi ya optique afite ibiciro bitandukanye ukurikije umubare wibyambu bya E1 byoherejwe.Mubisanzwe, insimburangingo ntoya ya optique irashobora kwanduza 4 E1, kandi nini nini ya optique irashobora kohereza 4032 E1.

Amashanyarazi ya optique agabanijwemo analog optique ya transiporo hamwe na optique ya optique:
1) Analog optique transceiver

Ikigereranyo cya optique transceiver ikoresha tekinoroji ya PFM yo kohereza ibimenyetso byamashusho mugihe nyacyo, nicyo gikoreshwa cyane muri iki gihe.Ihererekanyabubasha ryambere rikora modulisiyo ya PFM kumashusho yerekana amashusho, hanyuma ikora amashanyarazi-optique.Nyuma yikimenyetso cya optique cyoherejwe kumpera yakira, ikora optique-to-amashanyarazi, hanyuma ikora demodulation ya PFM kugirango igarure ibimenyetso bya videwo.Bitewe no gukoresha tekinoroji ya moderi ya PFM, intera yohereza irashobora kugera kuri 30 Km byoroshye, kandi intera yo kohereza ibicuruzwa bimwe ishobora kugera kuri 60 Km, cyangwa na kilometero amagana.Mubyongeyeho, ibimenyetso byamashusho bifite kugoreka gake nyuma yo koherezwa, hamwe nikimenyetso kinini-cy-urusaku hamwe no kugoreka bito bitari umurongo.Ukoresheje ikoreshwa rya tekinoroji ya tekinoroji ya tekinoroji, ihererekanyabubasha ryerekana amashusho nibimenyetso byamakuru birashobora kandi kugaragara kuri fibre optique kugirango ihuze ibikenewe byimishinga yo gukurikirana.

Ariko, iyi analog optique transceiver nayo ifite ibibi bimwe:
a) Gukemura ibibazo biragoye;
b) Biragoye kumenya imiyoboro myinshi yoherejwe hamwe na fibre imwe, kandi imikorere izatesha agaciro.Kugeza ubu, ubu bwoko bwa analog optique transceiver irashobora kohereza gusa amashusho-4 kumashusho kuri fibre imwe;
c) Kubera ko ikoreshwa rya analog modulation na demodulation ikoreshwa, ituze ryayo ntabwo iri hejuru bihagije.Hamwe no kongera igihe cyo gukoresha cyangwa guhindura ibiranga ibidukikije, imikorere ya optique ya transceiver nayo izahinduka, bizana bimwe mubitagenda neza kumushinga.

2) Transpiver ya Digital optique
Kubera ko ikoranabuhanga rya digitale rifite ibyiza bigaragara mubice byinshi ugereranije nubuhanga gakondo bwa analogi, nkuko tekinoroji ya digitale yasimbuye ikoranabuhanga risa mubice byinshi, digitisation ya optique ya transceiver nayo ni inzira byanze bikunze.Kugeza ubu, hari uburyo bubiri bwa tekiniki yuburyo bwa digitale ya optique transceiver: imwe ni MPEG II ishusho yogusenya amashusho ya optique ya transceiver, naho ubundi ni compression ya digitale optique transceiver.Kwiyerekana kwishusho Digitale optique ikoresha muri rusange ikoresha tekinoroji ya MPEG II yo guhuza amashusho, irashobora guhagarika amashusho yimuka muri N × 2Mbps yamakuru kandi ikohereza binyuze mumasoko asanzwe y'itumanaho cyangwa binyuze muri fibre optique.Bitewe no gukoresha tekinoroji yo guhuza amashusho, irashobora kugabanya cyane umurongo wohereza ibimenyetso.
