Gịnị bụ nkwukọrịta ikuku optical?

Nkwurịta Okwu Ikuku Ojii (OWC) bụ ụdị nkwukọrịta anya ebe a na-eji ìhè a na-ahụ anya, infrared (IR), ma ọ bụ ultraviolet (UV) na-ebufe mgbaàmà.

A na-akpọkarị sistemụ OWC nke na-arụ ọrụ na ogologo ebili mmiri a na-ahụ anya (390 — 750 nm) dị ka nkwukọrịta ìhè a na-ahụ anya (VLC). Sistemụ VLC na-eji diode na-ewepụta ìhè (LEDs) eme ihe ma nwee ike ịkụ aka n'ọsọ dị elu na-enweghị mmetụta a na-ahụ anya na mmepụta ọkụ na anya mmadụ. Enwere ike iji VLC mee ihe n'ọtụtụ ngwa dị iche iche gụnyere LAN ikuku, LAN nkeonwe na netwọk ụgbọala. N'aka nke ọzọ, sistemụ OWC nke dabere na ala, nke a makwaara dị ka sistemụ oghere oghere efu (FSO), na-arụ ọrụ na ugboro ole na ole dị nso na infrared (750 — 1600 nm). Sistemụ ndị a na-ejikarị laser emitters eme ihe ma na-enye njikọ doro anya na protocol dị ọnụ ala yana ọnụego data dị elu (ya bụ, 10 Gbit/s kwa ogologo ebili mmiri) ma na-enye ngwọta nwere ike inye nsogbu azụ. Mmasị na nkwukọrịta ultraviolet (UVC) na-etokwa n'ihi ọganihu ndị na-adịbeghị anya na isi mmalite/ihe nchọpụta ìhè siri ike na-arụ ọrụ na spectrum UV-blind sun spectrum (200 — 280 nm). N'ime ihe a na-akpọ eriri ultraviolet miri emi, radieshon anyanwụ adịghị mma n'ala, nke na-eme ka o kwe omume imepụta ihe nchọpụta foton-counting nwere ihe nnata sara mbara nke na-eme ka ike enwetara dịkwuo elu n'enweghị mgbakwunye mkpọtụ ndabere ọzọ.

Ruo ọtụtụ iri afọ, mmasị na nkwukọrịta ikuku anya ejedebela naanị na ngwa agha zoro ezo na ngwa mbara igwe gụnyere njikọ mbara igwe dị n'etiti satịlaịtị na oghere miri emi. Ruo taa, ntinye aka n'ahịa OWC ebelatala, mana IrDA bụ ngwọta nnyefe ikuku dị mkpụmkpụ nke na-aga nke ọma nke ukwuu.

Site na njikọ anya na sekit agbakwunyere ruo na njikọ njikọta n'èzí ruo na nkwukọrịta satịlaịtị, enwere ike iji ụdị nkwukọrịta ikuku anya dị iche iche mee ihe n'ọtụtụ ngwa nkwukọrịta dị iche iche.

Enwere ike kewaa nkwukọrịta ikuku anya n'ime ụdị ise dịka oke nnyefe si dị:

1. Ebe dị anya nke ukwuu

Nkwukọrịta Interchip n'ime ngwugwu multi-chip a kpọkọtara ma sie ike.

2. Ebe dị anya dị mkpirikpi

N'ihe gbasara IEEE 802.15.7, nkwukọrịta mmiri n'okpuru ikuku n'okpuru ikuku Body Local Area Network (WBAN) na ngwa ikuku Personal Local Area Network (WPAN).

3. Oke dị n'etiti

Nkwukọrịta ọkụ dị n'ime ụlọ na nke a na-ahụ anya (VLC) maka netwọk mpaghara ikuku (WLans) yana nkwukọrịta ụgbọala-ruo-ụgbọala na ụgbọala-ruo-ụgbọala.

Nzọụkwụ nke 4: N'ebe dị anya

Njikọta ụlọ, nke a makwaara dị ka nkwukọrịta oghere oghere efu (FSO).

5. Anya ọzọ

Nkwukọrịta laser n'ime mbara igwe, karịsịa maka njikọ dị n'etiti satịlaịtị na ntọala nke kpakpando satịlaịtị.
