Ukuqaliswa kweenkqubo ezahlukeneyo ze-PON 1. iteknoloji ye-APON Phakathi kwiminyaka yee-1990, abanye abaqhubi benethiwekhi abakhulu baseka i-Full Service Access Network Alliance (FSAN), injongo yayo kukuqulunqa umgangatho odibeneyo wezixhobo ze-PON ukuze abenzi bezixhobo kunye nabaqhubi bangene I-PON eq...

Ngophuhliso lwezixeko zanamhlanje ezisingise kwimisebenzi emininzi, ubume bedolophu buba nzima ngakumbi nangakumbi, kwaye kukho amakhulu, amakhulu, okanye amawaka eendawo zokubeka iliso emhlabeni. Ukuqinisekisa ukuba amasebe asebenzayo ayakwazi ukubamba umfanekiso wevidiyo wexesha lokwenyani, ocacileyo kunye nokumgangatho ophezulu...

Ukukhokela: I-100G Ethernet ukusuka kuphando ukuya kwintengiso, idinga ukuxazulula iteknoloji engundoqo ye-interface, ukupakishwa, ukuhanjiswa, amacandelo abalulekileyo, njl njl. Ubuchwephesha obuphambili be-interface ye-100G ye-Ethernet yangoku iquka umgca womzimba, iteknoloji yokuguqulwa kwesiteshi, i-multi-fiber channel kunye ne-wave wave. I-sub-mult...

I-1.Isakhiwo esisisiseko se-PON PON (i-Passive Optical Network) i-PON yi-fiber-fiber bidirectional optical access network usebenzisa i-point-to-multipoint (P2MP) isakhiwo. Inkqubo ye-PON yenziwe nge-terminal ye-optical line (OLT), i-optical distribution network (ODN), kunye ne-optical network unit (ONU) kwi...

1.Icandelo leLaser I-laser iyona nxalenye ephambili yemodyuli ye-optical injecting current kwi-semiconductor material kwaye ikhupha ukukhanya kwe-laser ngokusebenzisa i-photon oscillations kunye nokuzuza kwi-cavity. Okwangoku, ezona lasers ziqhele ukusetyenziswa yiFP kunye neDFB lasers. Umahluko kukuba i-sem...

Ingqiqo esisiseko yonxibelelwano lwefiber optical. I-fiber optical yi-dielectric optical waveguide, isakhiwo se-waveguide esithintela ukukhanya kwaye sisasaze ukukhanya kwi-axial direction. Ifiber entle kakhulu eyenziwe ngeglasi yequartz, i-synthetic resin, njl njl. Ifiber yemowudi enye: i-core 8-10um, i-cladding 125um Multimo...
