Kuyambitsidwa kwa machitidwe osiyanasiyana a PON 1. Ukadaulo wa APON M'katikati mwa zaka za m'ma 1990, ogwiritsira ntchito maukonde akuluakulu adakhazikitsa Full Service Access Network Alliance (FSAN), omwe cholinga chake ndi kupanga mulingo wogwirizana wa zida za PON kuti opanga zida ndi ogwiritsa ntchito athe kulowa. PON ndi...

Ndi chitukuko cha mizinda yamakono kupita ku ntchito zambiri, mapangidwe a m'matauni akukhala ovuta kwambiri, ndipo pali mazana, mazana, kapena zikwi za malo owunikira pansi. Kuwonetsetsa kuti madipatimenti ogwira ntchito atha kumvetsetsa zenizeni zenizeni, zomveka bwino komanso zapamwamba ...

Mtsogoleli: 100G Efaneti kuchokera ku kafukufuku kupita ku malonda, akufunika kuthetsa matekinoloje ofunikira a mawonekedwe, kulongedza, kutumiza, zigawo zikuluzikulu, ndi zina zotero. Njira zamakono zamakono zamakono za 100G Ethernet zikuphatikizapo kusanjika kwa thupi, teknoloji yosinthira njira, njira zambiri za fiber ndi wave. Zambiri ...

1.Basic structure ya PON PON (Passive Optical Network) PON ndi imodzi ya fiber bidirectional optical access network pogwiritsa ntchito mfundo-to-multipoint (P2MP). Dongosolo la PON limapangidwa ndi optical line terminal (OLT), optical distribution network (ODN), ndi optical network unit (ONU) pa...

1.Laser gulu A laser ndi gawo lapakati kwambiri la optical module yomwe imalowetsa panopa mu semiconductor material ndipo imatulutsa kuwala kwa laser kupyolera mu photon oscillations ndi kupindula muzitsulo. Pakadali pano, ma laser omwe amagwiritsidwa ntchito kwambiri ndi FP ndi DFB lasers. Kusiyana kwake ndikuti sem ...

Lingaliro loyambira la kulumikizana kwa fiber. An optical fiber ndi dielectric optical waveguide, mawonekedwe a waveguide omwe amatchinga kuwala ndikufalitsa kuwala kwa axial direction. CHIKWANGWANI chabwino kwambiri chopangidwa ndi galasi la quartz, utomoni wopangira, etc. Single mode fiber: core 8-10um, cladding 125um Multimo ...
