Itumanaho ry'ikoranabuhanga rikoresha insinga rikoresha ikoranabuhanga rya optique ni iki?

Itumanaho ry’amajwi ridafite umugozi (OWC) ni ubwoko bw’itumanaho ry’amajwi aho ibimenyetso byoherezwa hakoreshejwe urumuri rugaragara, rudafite umurongo (IR), cyangwa urumuri rwa ultraviolet (UV).

Sisitemu za OWC zikora ku bunini bw'urumuri bugaragara (390 - 750 nm) zikunze kwitwa itumanaho ry'urumuri rugaragara (VLC). Sisitemu za VLC zikoresha diode zitanga urumuri (LEDs) kandi zishobora gutera umuvuduko mwinshi cyane nta ngaruka zigaragara ku itara n'ijisho ry'umuntu. VLC ishobora gukoreshwa mu buryo butandukanye burimo LAN idakoresha insinga, LAN y'umuntu idakoresha insinga n'imiyoboro y'imodoka. Ku rundi ruhande, sisitemu za OWC zishingiye ku butaka, zizwi kandi nka sisitemu za optique y'umwanya wigenga (FSO), zikora ku bunini bwa infrared (750 - 1600 nm). Izi sisitemu zikoresha imiyoboro ya laser kandi zitanga protocole transparent links zihendutse hamwe n'umuvuduko mwinshi w'amakuru (ni ukuvuga 10 Gbit / s kuri buri bunini bw'urumuri) kandi zigatanga igisubizo gishobora kugabanya ibibazo byo mu kirere. Gushishikazwa n'itumanaho rya ultraviolet (UVC) nabyo biri kwiyongera bitewe n'iterambere riherutse mu miterere y'urumuri rwa solid-state / detectors zikora muri spectrum ya UV idakoresha izuba (200 - 280 nm). Muri uyu muyoboro witwa deep ultraviolet band, imirasire y'izuba ntabwo igaragara cyane ku butaka, bigatuma habaho igishushanyo mbonera cy'icyuma gipima fotoni gifite icyuma gikira urumuri cyiyongera ingufu zakiriwe hatabayeho kongeramo urusaku rw'inyongera inyuma.

Mu myaka ibarirwa muri za mirongo, ubushake mu itumanaho rikoresha insinga za optique bwagabanutse cyane cyane ku bikorwa bya gisirikare byihishe no ku bikorwa byo mu kirere birimo intersatellite n'ibijyanye n'ikirere cyimbitse. Kugeza ubu, kwinjira ku isoko rya OWC byari bike, ariko IrDA ni igisubizo cyiza cyane cyo kohereza insinga mu ntera ngufi.

Kuva ku guhuza itumanaho hakoreshejwe ikoranabuhanga rya optique mu buryo bwa "integrated circuits" kugeza ku guhuza itumanaho ryo hanze kugeza ku itumanaho rya satelite, ubwoko butandukanye bw'itumanaho rikoresha ikoranabuhanga rya optique rishobora gukoreshwa mu buryo butandukanye bw'itumanaho.

Itumanaho rikoresha umuyoboro w’itumanaho rikoresha umuyoboro w’itumanaho rishobora kugabanywamo ibyiciro bitanu hakurikijwe urwego rw’itumanaho:

1. Intera ngufi cyane

Itumanaho hagati ya chips mu mapaki afite chips nyinshi kandi zipakiye neza.

2. Intera ngufi

Muri gahunda isanzwe ya IEEE 802.15.7, itumanaho ryo munsi y'amazi rikoreshwa mu buryo butaziguye hifashishijwe umuyoboro wa interineti w'ahantu hadakoreshejwe insinga (WBAN) na porogaramu za interineti z'ahantu hadakoreshejwe insinga (WPAN).

3. Intera iri hagati

Itumanaho ry’imbere mu kirere n’urumuri rugaragara (VLC) ku miyoboro ya interineti idafite insinga (WLans) ndetse n’itumanaho hagati y’ikinyabiziga n’ikinyabiziga n’ibikorwa remezo.

Intambwe ya 4: Kure

Uburyo bwo guhuza ibikorwa, buzwi kandi nka itumanaho ry’ahantu higenga (FSO).

5. Intera y'inyongera

Itumanaho rya laser mu kirere, cyane cyane ku bijyanye n'isano riri hagati y'ibyogajuru n'ishyirwaho ry'ibice by'ibyogajuru.
