Itumanaho rya optique ni iki?

Optical Wireless Communication (OWC) nuburyo bwitumanaho rya optique aho ibimenyetso bitangwa hakoreshejwe urumuri rutagaragara, infragre (IR), cyangwa ultraviolet (UV).

Sisitemu ya OWC ikorera ku burebure bugaragara (390 - 750 nm) bakunze kwita itumanaho rigaragara (VLC). Sisitemu ya VLC yifashisha diode itanga urumuri (leds) kandi irashobora guhindagurika kumuvuduko mwinshi cyane nta ngaruka zigaragara ziva kumatara nijisho ryumuntu. VLC irashobora gukoreshwa muburyo butandukanye bwa porogaramu zirimo LAN idafite umugozi, LAN itagira umugozi hamwe n’imodoka. Ku rundi ruhande, sisitemu ishingiye kuri point-to-point ya OWC, izwi kandi nka sisitemu yubusa ya optique (FSO), ikorera kumurongo wa infragre (750 - 1600 nm). Ubu buryo busanzwe bukoresha ibyuma bisohora laser kandi bigatanga amahame-yingirakamaro ya protocole mu mucyo hamwe n’ibiciro biri hejuru (urugero 10 Gbit / s kuri buri muhengeri) kandi bigatanga igisubizo gishobora gukemura ibibazo. Ishyaka ryitumanaho rya ultraviolet (UVC) naryo riragenda ryiyongera kubera iterambere rya vuba mumasoko akomeye yumucyo / detector ikorera mumirasire y'izuba itabona izuba (200 - 280 nm). Muri iri tsinda ryitwa ultraviolet ryimbitse, imirasire yizuba ntisanzwe kurwego rwubutaka, bigatuma bishoboka igishushanyo mbonera kibara fotone hamwe numurima mugari wakira ingufu zakiriwe utongeyeho urusaku rwinyuma.

Mu myaka ibarirwa muri za mirongo, inyungu mu itumanaho rya optique ryagarukiye cyane cyane mubikorwa bya gisirikare rwihishwa hamwe nibisabwa mu kirere harimo interineti ihuza abantu benshi. Kugeza ubu, isoko rya OWC ryinjira mu isoko ryaragabanutse, ariko IrDA ni igisubizo cyiza cyane cyogukwirakwiza imiyoboro mito mito.

Kuva kuri optique ihuza imiyoboro ihuriweho kugeza hanze ihuza imiyoboro ihuza itumanaho rya satelite, impinduka zitumanaho rya optique zirashobora gukoreshwa muburyo butandukanye bwo gutumanaho.

Itumanaho rya optique rishobora kugabanywamo ibyiciro bitanu ukurikije uburyo bwo kohereza:

1. Intera ngufi cyane

Itumanaho ryitumanaho muburyo bukusanyirijwe hamwe kandi bipakiye cyane.

2. Intera ngufi

Mubisanzwe IEEE 802.15.7, itumanaho ryamazi munsi yumurongo wumudugudu wumudugudu (WBAN) hamwe numuyoboro wihariye wibanze (WPAN).

3. Urwego ruciriritse

Imbere muri IR hamwe n’itumanaho rigaragara (VLC) kumiyoboro yaho idafite umugozi (WLans) kimwe n’imodoka-ku-modoka n’itumanaho-remezo.

Intambwe ya 4: Remote

Guhuza imiyoboro, bizwi kandi nk'itumanaho ryubusa rya optique (FSO).

5. Intera irenze

Itumanaho rya Laser mu kirere, cyane cyane ku masano hagati ya satelite no gushyiraho inyenyeri zo mu kirere.
