Nkwukọrịta Optic Fiber

Optical fiber communication refers to a way of transmitting information using light and optical fiber, which is a kind of wired communication. Light modulated to carry information.

Kedu mgbe nkwukọrịta fiber optic pụtara?

Nkwurịta okwu fiber anya bụ isi ụzọ nnyefe nke netwọk nkwurịta okwu ọgbara ọhụrụ. Akụkọ mmepe ya bụ naanị afọ iri ma ọ bụ iri abụọ, o we gabiga ọb͕ọ atọ: multimode ogologo-wavelength eriri, ogologo-wavelength multimode eriri na ogologo-wavelength otu-mode eriri. The use of fiber optic communication is the history of communication. Nkwenye nke nkwurịta okwu fiber optical bụ nnukwu mgbanwe na akụkọ ihe mere eme nke nzikọrịta ozi. Karịrị 20 obodo gụnyere United States, Japan, United Kingdom, na France ekwuputala nkwa ha na mmepe nke mgbasa ozi fiber optical, na agakwaghị wuo ngwa anya cable nkwurịta okwu ahịrị.

Ọmụmụ na mmepe nke nkwurịta okwu fiber anya bụ mgbanwe dị mkpa na akụkọ ihe mere eme nke nkwukọrịta, na nzikọrịta ozi satịlaịtị na nzikọrịta ekwentị ka edepụtara dịka teknụzụ na 1990s. Mgbe ịbanye na narị afọ nke 21st, n'ihi mmepe ngwa ngwa nke ọrụ ịntanetị yana uto nke ọdịyo, vidiyo, data, na ngwa mgbasa ozi, enwere mkpa ngwa ngwa maka ikike buru ibu (ultra-high-speed na ultra-ogologo-anya) Sistemụ nnyefe ngwa anya na netwọkụ.
