Ulwazi

Ngokuthuthukiswa kwesistimu yokuxhumana ye-optical enebanga elide, umthamo omkhulu kanye nesivinini esiphezulu, ikakhulukazi uma izinga elilodwa lamagagasi lishintsha ukusuka ku-40g kuya ku-100g noma ngisho ne-super 100g, ukuhlakazeka kwe-chromatic, umphumela ongaqondile, ukuhlakazeka kwemodi ye-polarization kanye neminye imiphumela yokudlulisela ekukhetheni. .

Isandulelo esithi FTTH sisho ifayibha ekhaya futhi ngokuqondile kumatheminali abasebenzisi. Lobu futhi ubuchwepheshe ebesibuphishekela futhi sibuhlola iminyaka engaphezu kwengama-20. Ngenxa yokuphumelela okuqhubekayo kwezindleko, ubuchwepheshe, isidingo nokunye, lobu buchwepheshe buye bakhuthazwa futhi bathuthukiswa kabanzi. Kwabezindaba...

I-1) Isandulelo: Ngokuvela okusheshayo kwamabhizinisi ahlukahlukene, izimboni ezengeziwe ziyaqaphela ukuthi kuyadingeka ukugqekeza "ibhodlela" le-bandwidth ngokushesha ngangokunokwenzeka, futhi i-optical fiber iyindlela engcono kakhulu yokudlulisa. I-Optical fiber inezinzuzo ezimbili ngaphezu kwe ...

Umsebenzi wokubuka izibalo zomlayezo: faka "isikhombikubona sombukiso" kumyalo ukuze ubuke amaphakethe angalungile ngaphakathi nangaphandle kwechweba, bese wenza izibalo zokunquma ukukhula kwevolumu, ukuze wahlulele inkinga yephutha. 1) Okokuqala, i-CEC, ifreyimu, namaphakethe wephutha we-throttles avela ku-t...

Uma isixhumi esibonakalayo semojula ye-optical efakiwe yehluleka ukusebenza kahle, ungakwazi ukuxazulula inkinga usebenzisa izindlela ezintathu ezilandelayo: 1)Hlola ulwazi lwe-Alarm lwemojula yokubona. Ngolwazi lwe-alamu, uma kunenkinga ngokwamukela, ngokuvamile kubangelwa...

Inani lamandla okukhanya lizoba nomthelela onembile futhi osobala esignali ngesikhathi senqubo yokudlulisa, futhi lawa mandla okukhanya nawo alula ukuhlola. Leli nani lingahlolwa ngamandla okubona. Amandla okubona - sebenzisa imitha yamandla okubona ukuze uhlole ukuthi...
