Nkwukọrịta Fiber Optical
Teknụzụ nzikọrịta ozi nke fiber optical esitela na nzikọrịta ozi anya wee bụrụ otu n'ime isi ogidi nke nzikọrịta ozi ọgbara ọhụrụ.Ọ na-arụ ọrụ dị mkpa na netwọk mgbasa ozi nke oge a.

Njirimara nke nzikọrịta ozi eriri anya
1.Broadband ike ozi dị ukwuu
Ike nkwurịta okwu fiber optical dị ukwuu, na obosara nnyefe nke eriri anya dị ukwuu karịa obosara nke eriri ma ọ bụ waya ọla kọpa.Otú ọ dị, maka usoro eriri anya nke otu wavelength, ebe ọ bụ na ngwaọrụ njedebe dị oke oke, a naghị egosipụta obosara nnyefe nke eriri anya.Ya mere, a chọrọ usoro sayensị iji mee ka ikike mgbasa ozi dịkwuo elu.
2.Low ọnwụ, nwere ike ibunye n'ebe dị anya
Ọnụego ọnwụ nke nzikọrịta eriri anya dị ala karịa ọnụego nzikọrịta ozi nkịtị.The ngwa anya eriri bụghị nanị nwere obere ọnwụ, ma nwekwara ike na-ekwurịta okwu n'elu ogologo anya.Ogologo nkwurịta okwu kachasị ogologo nwere ike iru ihe karịrị mita 10,000, ya mere nkwurịta okwu fiber optical bara uru maka netwọk mmekọrịta.Ebe a na-atụnyere ọnụọgụ ozi na ọnụ ahịa nkwurịta okwu fiber-optic dị oke elu, yana nchekwa dị mma.
3. Strong mgbochi electromagnetic nnyonye anya
The ngwa anya eriri bụ tumadi ihe insulator ihe mere nke quartz dị ka a akụrụngwa, na ihe onwunwe bụ magburu onwe na mkpuchi na-adịghị mfe corroded.The kasị mkpa atụmatụ nke ngwa anya eriri nkwurịta okwu bụ ya ike mgbochi electromagnetic nnyonye anya ike, na ọ bụghị ya. emetụta eke sunspot ọrụ, ionospheric mgbanwe na àmụmà nnyonye anya, na ọ bụghị n'okpuru artificial electromagnetic nnyonye anya.Na ngwa anya eriri nkwurịta okwu nwekwara ike jikọta ya na ike eduzi na-etolite a abụọ-ahiri ngwa anya cable ma ọ bụ yiri na elu voltaji. eriri ọkụ.Njirimara a nke nkwurịta okwu fiber optic na-arụ ọrụ dị ukwuu na usoro nkwurịta okwu n'ọhịa nke ike eletrik siri ike.Enwere ike itinye nkwurịta okwu ike anya na ndị agha n'ihi na ọ nwere ike nweere onwe ya pụọ na nnyonye anya nke usu electromagnetic.
4.Good nchekwa na nzuzo
Na nnyefe nke ebili mmiri redio n'oge gara aga, ebe ọ bụ na ebili mmiri electromagnetic na-adaba n'oge usoro mgbasa ozi, a na-ebute nnyonye anya nke usoro mgbasa ozi dị iche iche, na nzuzo adịghị mma. Otú ọ dị, nkwurịta okwu fiber optical na-ejikarị ebili mmiri ọkụ na-ebufe mgbaàmà.A na-ejikọta akara ngosi anya kpamkpam na nhazi nke waveguide ngwa anya, na ụzarị ndị ọzọ na-agbapụta na-etinye uche na mpụta nke eriri anya, ọbụlagodi na mgbanaka nwere ọnọdụ ọjọọ ma ọ bụ akụkụ.Enwekwara ntapu ebili mmiri ole na ole.Ọzọkwa, n'ime usoro nkwukọrịta fiber optic, enwere ike itinye ọtụtụ eriri eriri anya n'otu eriri anya na-enweghị nnyonye anya.Ya mere, nkwurịta okwu eriri anya nwere ikike mgbochi mgbochi siri ike na nzuzo, yana ọrụ nchekwa nke nkwurịta okwu eriri anya dịkwa oke elu.
