Umuyoboro wa optique (uzwi cyane nka optique injangwe cyangwa modem optique), bivuga kwanduza binyuze kuri the fibre iciriritse, optique ya optique modulation na demodulation kubindi bimenyetso bya protocole yibikoresho byurusobe. Igikoresho cya Lightcat gikora nkigikoresho cyohereza imiyoboro minini yaho, imiyoboro ya metero nkuru hamwe nuyoboro mugari. Bitandukanye na optique ya optique, optique ya optique yakira gusa kandi ikanatanga urumuri, kandi ntabwo ikubiyemo guhindura protocole.
Modem nigikoresho cya elegitoronike gihindura ibimenyetso bya digitale kubimenyetso bisa kugirango byandikirwe, kandi bigabanya ibimenyetso byakiriwe kugirango ubone ibimenyetso bya digitale. Intego yacyo ni ugukora ibimenyetso bisa bishobora kwanduzwa byoroshye no kugarura digita yumwimererel ikimenyetso mukoresheje decoding. Ukurikije porogaramu, MODEM irashobora gukoresha uburyo butandukanye bwo kohereza ibimenyetso bisa, nka fibre optique, radio RF, cyangwa imirongo ya terefone.
Modem ya terefone ikoresha umurongo wamajwi kumurongo rusange wa terefone mugutumanaho amakuru ni most bikunze guhura na modem. Mu Cyongereza kivugwa, abantu benshi bavuga ko modem ya terefone ari "injangwe" cyangwa "amarozi" ishingiye ku murongo wa mbere w'icyongereza.
Ubundi modem isanzwe irimo modem ya kabili yo kubona amakuru yagutse, modem ya ADSL, na fibre modem. Terefone igendanwa ya digitale mubyukuri ni modem idafite umugozi. Ibikoresho bigezweho byo gutumanaho bigenewe kohereza amakuru menshi kure cyane kubitangazamakuru bitandukanye, bityo rero bikaba bishingiye kumikorere ya modem. Modem ya microwave irashobora gukoreshwa miriyoni ya bits kumasegonda. Modem ya optique ikoresheje fibre optique nkuko uburyo bwo kohereza bushobora kugera kuri Gbps zirenga icumi, ubu ni inkingi yo gutumanaho itumanaho Passive optique (Passive optique net), izwi kandi nka pasiporo optique ya fibre optique, ni ubwoko bwitumanaho rya fibre optique umuyoboro, urangwa no kutagira amashanyarazi kugirango utunganyirize ibimenyetso byuzuye, kimwe nindorerwamo murugo, ntabwo ikenera amashanyarazi kugirango igaragaze ishusho, usibye ibikoresho bya terefone bikenera gukoresha amashanyarazi, Imyanya hagati ikozwe ibintu byoroshye kandi bito bya fibre optique.
Ukurikije igitekerezo cya New Generation Network (NGN), umuyoboro w'itumanaho urashobora kugabanywamo ibice bibiri: umuyoboro wibanze hamwe nuyoboro. Umuyoboro wibanze uhwanye na relay gakondo n'imirongo miremire. Umuyoboro winjira ufite impeta ya fibre optique. Imikorere y'urusobekerane rwibanze hamwe nurusobe rwinjira biratandukanye, kandi uburyo bwo kohereza nabwo buratandukanye. Kubwibyo, porogaramu ya PON irashobora kugabanywamo ubwoko bubiri: PON yumuyoboro wibanze na PON yo kugera kumurongo. Iyambere ishingiye cyane cyane kuri WDM, naho iyanyuma ikoresha ibice byombi bya optique hamwe na WDM.
Ubumenyi bwavuzwe haruguru nibisobanuro bigufi kubyerekeranye numuyoboro wa optique uzanwa na Shenzhen HDV Phoelectron Technology LTD., Ni uruganda rukora ibikoresho byitumanaho nkibicuruzwa byingenzi. Ibikoresho byabo bifitanye isano na:oltonu/ umunyabwengeonu/ aconu/ fibreonu/ catvonu/ gpononu/ xpononu/ oltibikoresho /olthindura/ gponolt/ eponoltnibindi, ikaze abakoresha kuza kugisha inama ibicuruzwa.
