UdushyaRF hejuru ya fibreigisubizo
Muri iki gihe, imiterere y’amashanyarazi igenda irushaho kuba ingorabahizi ndetse no kugaragara kw’ibimenyetso bihindagurika, uburyo bwo kugera ku buryo bworoshye, bwo kureshya no ku buryo buhamye bw’ibimenyetso by’amashanyarazi byagutse byabaye imbogamizi ikomeye mu bijyanye no gupima no gupima mu nganda. Uburyo bwa RF over fiber analog broadband optical transceiver link ni uburyo bushya bwo guhanga udushya.kohereza fibre y'urumuriigisubizo cyagenewe gukemura iki kibazo.
Iki gikoresho gishyigikira gukusanya no kohereza ibimenyetso bya interineti biva kuri DC bijya kuri 1GHz mu buryo bwihuse, kandi gishobora guhindurwa mu buryo bworoshye n'ibikoresho bitandukanye byo gutahura, birimo ibikoresho bipima ubu, ibikoresho bifite voltage nyinshi n'ibindi bikoresho bipima inshuro nyinshi. Iherezo ryacyo ryo kohereza rifite uburyo bwa 1 MΩ/50 Ω bushobora guhindurwamo BNC, bufite uburyo bwo guhuza n'amakuru menshi. Mu gihe cyo gutunganya ibimenyetso, ibimenyetso by'amashanyarazi birahindurwa bigahindurwamo ibimenyetso by'urumuri, hanyuma byoherezwa ku mpera yo kwakira binyuze mu migozi y'urumuri ikoresha uburyo bumwe hanyuma bigasubizwa neza ku bimenyetso by'amashanyarazi bya mbere hakoreshejwe module yo kwakira.
Ni ngombwa kuvuga ko uruhererekane rwa R-ROFxxxxT ruhuza uburyo bwo kugenzura urwego rw'ikoranabuhanga (ALC), bushobora kurwanya neza ihindagurika ry'ibimenyetso riterwa no gutakaza fibre no kwemeza ko imikorere ihoraho mu gihe cyo kohereza amakuru mu ntera ndende. Byongeye kandi, module yo kohereza amakuru ifite agakoresho gatuma amakuru ahindagurika kandi gashobora guhinduka, gashyigikira impinduka eshatu zihinduka za 1: 1/10: 1/100: 1. Ibi bituma abakoresha bashobora kunoza urwego rwo kwakira ibimenyetso hashingiwe ku bintu nyabyo no kwagura urwego ruhindagurika rwa sisitemu.
Kugira ngo huzuzwe ibisabwa mu igerageza rya mudasobwa cyangwa igendanwa, uru ruhererekane rw'amamodoka rushyigikira umuriro wa bateri na remote control, kandi rufite uburyo bwo guhagarara bwihuse bwinjira mu buryo bwikora mu gihe nta ngufu zikoreshwa, bigatuma bateri y'igikoresho iramba. Amatara ya LED ari imbere atanga ibitekerezo by'igihe nyacyo ku mikorere, birushaho kongera ubushobozi bwo gukora no gukoresha neza ibikoresho.
Haba mu bihe nko kugenzura ingufu, gupima umurongo wa radiyo, cyangwa igerageza ry’ubushakashatsi bwa siyansi, uruhererekane rwa R-ROFxxxxT rushobora guha abakoresha ibisubizo byizewe, byoroshye kandi birwanya cyane uburyo bwo kohereza amajwi ari kure.
Ibisobanuro by'ibicuruzwa bya RF hejuru ya fibre
Urukurikirane rwa R-ROFxxxxTRF hejuru y'umugozi w'inyuziIhuza rya transceiver ya analog broadband optical transceiver ni igikoresho cyo kohereza amakuru cya fiber optic kure cyagenewe gupima ibimenyetso by'amashanyarazi bya DC kugeza kuri 1GHz mu buryo bw'igihe nyacyo mu bidukikije bigoye bya elegitoronike. Module yo kohereza amakuru ifite 1 MΩ/50 Ω BNC input, ishobora guhuzwa n'ibikoresho bitandukanye byo kumva (probes zigezweho, probes zifite voltage nyinshi cyangwa ibikoresho byihariye byo gupima inshuro nyinshi). Muri module yo kohereza amakuru, ikimenyetso cy'amashanyarazi cyinjiye kirahinduka kigahindurwamo ikimenyetso cy'amashanyarazi, hanyuma cyoherezwa muri module yo kwakira amakuru binyuze muri fibre optique imwe. Module yo kwakira amakuru ihindura ikimenyetso cy'amashanyarazi mo ikimenyetso cy'amashanyarazi. Kohereza amakuru y'amashanyarazi bigengwa no kugenzura urwego rw'amashanyarazi kugira ngo bikomeze gukora neza kandi bihoraho, bitagize ingaruka ku gutakaza amakuru. Module zombi zo kwakira amakuru zishyigikira umuriro wa bateri na remote control. Module yo kohereza amakuru y'amashanyarazi irimo kandi attenuator ihindagurika ishobora guhinduka (1: 1/10: 1/100: 1) yo guhindura urwego rw'ibimenyetso byakiriwe kugira ngo binoze urwego rw'amashanyarazi. Byongeye kandi, iyo igikoresho kidakoreshwa, gishobora kwinjizwa kure mu buryo bwo guhagarara bufite ingufu nke kugira ngo kizigame ingufu za bateri, kandi itara rya LED ryerekana imikorere.
Ibiranga ibicuruzwa
Umuyoboro wa DC-500 MHZ/DC-1 GHZ ni ubushake
Indishyi y'igihombo cyo gushyiramo optique idahindagurika
Inyungu irahinduka kandi urwego rw'ingufu z'injira ruranozwa
Ifasha mu gucunga kure kandi ikoresha batiri, bigatuma yoroherwa no gukoreshwa hanze
