I-Optical fibre zokuxhumana iyindlela eyinhloko yokudlulisa amanethiwekhi okuxhumana esimanje.Umlando wokuthuthuka kwayo ishumi leminyaka elilodwa noma amabili kuphela.Ihlangabezane nezizukulwane ezintathu: i-short-wavelength multimode fiber, i-long-wavelength multimode fiber kanye ne-long-wavelength single-mode fiber.

Ngokuthuthuka okusheshayo kwe-inthanethi, ibanga lokudlulisela lamapheya asontekile kanye nomthelela wokuphazamiseka kazibuthe kagesi kunqunyelwe, okukhawulela ukuthuthukiswa kwenethiwekhi.Ngakho-ke, i-transceiver optical iye yavela.Ukusetshenziswa kwe-fiber optic transceivers kuthatha indawo ...

Ngemva kokufakwa kwe-module optical, ukuhlola ukusebenza kwayo kuyisinyathelo esibalulekile.Lapho izingxenye ze-optical kuwo wonke uhlelo lwenethiwekhi zinikezwa umthengisi ofanayo, uma uhlelo lwenethiwekhi lungasebenza ngokujwayelekile, asikho isidingo sokuhlola ngokwehlukana izingxenye ezingaphansi. yohlelo.Nokho, iningi...

I-Optical Fiber Communication I-Optical fibre communication technology iye yavela ekuxhumaneni okubonakalayo futhi isibe yizinsika eziyinhloko zokuxhumana zesimanje.Idlala indima ebalulekile kumanethiwekhi esimanjemanje ezokuxhumana.Njengobuchwepheshe obusafufusa, ukuxhumana nge-fiber optical sekuthuthukile...

Njengamanje, umncintiswano ozungeze i-5G ushisa ngokushesha emhlabeni jikelele, futhi amazwe anobuchwepheshe obuhamba phambili ayaqhudelana ukuze akhiphe amanethiwekhi awo e-5G.I-South Korea ihambe phambili ekusunguleni inethiwekhi yokuqala yezohwebo ye-5G emhlabeni ngo-Ephreli kulo nyaka.Izinsuku ezimbili kamuva, i-US telec...

Umgomo wokuxhumana obonakalayo Umgomo wokuxhumana umi kanje.Ekugcineni kokuthumela, ulwazi oludlulisiwe (njengezwi) kufanele luguqulwe lube amasignali kagesi kuqala, bese amasignali kagesi ashintshwa abe yilaser ekhishwa yi-laser (umthombo wokukhanya) , ngakho t...
