[Mawu Oyamba] Ukadaulo wogawa wavelength wochulukitsa ukhoza kugwiritsa ntchito mokwanira zida zazikulu za bandwidth zomwe zimabweretsedwa ndi malo otsika otsika a fiber single-mode. Malingana ndi mafupipafupi (kapena kutalika kwa mawonekedwe) a kuwala kwa njira iliyonse, gawani zenera lochepa la fiber mu njira zingapo, gwiritsani ntchito kuwala kwa kuwala monga chonyamulira chizindikiro, ndipo mugwiritseni ntchito multiplexer wavelength division multiplexer (multiplexer) pa mapeto otumizira.
Ukadaulo wogawika wavelength utha kugwiritsa ntchito mokwanira zida zazikulu za bandwidth zomwe zimabweretsedwa ndi gawo lotsika lotsika la fiber single-mode. Malingana ndi mafupipafupi (kapena kutalika kwa mawonekedwe) a kuwala kwa njira iliyonse, zenera lochepa la optical fiber limagawidwa m'njira zingapo, kuwala kwa kuwala kumagwiritsidwa ntchito ngati chonyamulira cha chizindikiro, ndi multiplexer wavelength division multiplexer (multiplexer). ) imagwiritsidwa ntchito kumapeto kwa kutumiza. Zonyamulira za kuwala kwa mafundewa zimaphatikizidwa ndikutumizidwa mu fiber optical kuti zitumizidwe. Pamapeto olandila, gawo la wavelength division multiplexer (wave splitter) limalekanitsa zonyamulira zowoneka bwinozi zomwe zimanyamula zizindikilo zosiyanasiyana pamafunde osiyanasiyana. Popeza kuti zizindikiro zonyamula kuwala zamitundu yosiyanasiyana zimatha kuonedwa ngati zodziyimira pawokha (popanda kuganizira za kusakhazikika kwa fiber optical), kuchulukitsa ndi kufalitsa ma siginecha angapo optical kumatha kuzindikirika mumtundu umodzi wa optical.
Fiber Access Technology
Ma optical fiber access network ndiye "makilomita omaliza" amsewu wazidziwitso. Kuti mukwaniritse kufalitsa kwachidziwitso chothamanga kwambiri ndikukwaniritsa zosowa za anthu, osati maukonde otumizira msana wa Broadband, komanso gawo lofikira la ogwiritsa ntchito ndilofunika kwambiri. Optical fiber access network ndiye ukadaulo wofunikira kuti chidziwitso chothamanga kwambiri chilowe m'mabanja masauzande ambiri. Mu optical fiber broadband access, chifukwa cha malo osiyanasiyana ofikira a ulusi wa kuwala, pali ntchito zosiyanasiyana monga FTTB, FTTC, FTTCab ndi FTTH, zomwe zimatchedwa FTTx. Chifukwa chake, imatha kugwiritsa ntchito mokwanira mawonekedwe a Broadband optical fibers, kupatsa ogwiritsa ntchito bandwidth yofunikira yopanda malire, ndikukwaniritsa mokwanira zosowa za burodibandi. Pakalipano, teknoloji yapakhomo ikhoza kupatsa ogwiritsa ntchito FE kapena GE bandwidth, yomwe ndi njira yabwino yopezera ogwiritsa ntchito mabizinesi akuluakulu ndi apakatikati.
Kukula kwa Optical Fiber Communication Technology
M'zaka zaposachedwa, ndi kupita patsogolo kwaukadaulo, kusintha kwa kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka anthu. Chotsatirachi ndichidule chachidule cha malo omwe ali ndi chitukuko chachikulu cha optical fiber communication. Kufotokozera ndi chiyembekezo, chitukuko cha machitidwe othamanga kwambiri, kusinthika kwa machitidwe a WDM apamwamba kwambiri.
Tikayang'ana pa chitukuko cha kuwala CHIKWANGWANI kulankhulana m'zaka zaposachedwapa, kumanga dziko nsana kuwala maukonde kuti ndi mandala kwambiri, kusinthasintha kwambiri ndi kopitilira muyeso-lalikulu mphamvu sangakhoze kokha kuyala maziko olimba thupi tsogolo National Information Infrastructure (NII), koma komanso makampani odziwa zambiri a dziko langa m'zaka 100 zikubwerazi ndi kuchoka kwa chuma cha dziko ndi chitetezo cha dziko ndizofunika kwambiri. Kukula kwamakampani olumikizirana ndi optical fiber ndi njira yosasinthika yolumikizirana yamakono.
