UdushyaRF hejuru ya fibreigisubizo

Muri iki gihe kirushijeho kuba ingorabahizi ya electromagnetiki no guhora hagaragara ibimenyetso byerekana ibimenyetso, uburyo bwo kugera ku budahemuka bukabije, intera ndende kandi ihererekanyabubasha ry’amashanyarazi yagutse byabaye ikibazo gikomeye mu bijyanye no gupima no gupima inganda. RF hejuru ya fibre analog Broadband optique transceiver ihuza ni udushyakwanduza fibre optiqueigisubizo cyagenewe gukemura iki kibazo.

Iki gikoresho gishyigikira igihe nyacyo cyo gukusanya no kohereza ibimenyetso bya Broadband kuva DC kugeza 1GHz, kandi birashobora guhuzwa neza nibikoresho bitandukanye byo gutahura, harimo nubushakashatsi bwubu, amashanyarazi menshi hamwe nibindi bikoresho byo gupima inshuro nyinshi. Impera yacyo yohereza ifite 1 MΩ / 50 Ω ihinduranya BNC yinjiza, igaragaramo ubwuzuzanye. Mugihe cyo gutunganya ibimenyetso, ibimenyetso byamashanyarazi byahinduwe kandi bigahinduka mubimenyetso bya optique, hanyuma bigahita byoherezwa kumpera yakira hakoreshejwe fibre optique ya fibre optique hanyuma igasubizwa neza mubyuma byamashanyarazi byumwimerere na module yakira.

Twabibutsa ko urukurikirane rwa R-ROFxxxxT ruhuza uburyo bwikora bwo kugenzura urwego rwikora (ALC), rushobora guhangana neza n’imihindagurikire y’ibimenyetso biterwa no gutakaza fibre kandi ikemeza imikorere ihoraho mugihe cyoherejwe kure. Mubyongeyeho, uburyo bwo kohereza bufite ibikoresho byo guhuza n'imiterere kandi bigahinduka, bishyigikira ibintu bitatu byahinduwe 1: 1/10: 1/100: 1. Ibi bifasha abakoresha guhitamo urwego rwo kwakira ibimenyetso rushingiye kubintu bifatika no kwagura urwego rwa sisitemu.

Kugirango uhuze ibisabwa byumurima cyangwa igendanwa, uru ruhererekane rwamasomo rushyigikira amashanyarazi ya batiri no kugenzura kure, kandi rugaragaza uburyo bwubwenge bwihagararaho bwinjira bwinjira mumashanyarazi make mugihe kidakoreshwa, bikongerera neza ubuzima bwa bateri. Amatara yerekana LED kumurongo wimbere atanga ibitekerezo-nyabyo kumikorere, bikarushaho kunoza imikorere nibikorwa byibikoresho.

Haba mubihe nko gukurikirana ingufu, gupima radiyo, cyangwa ubushakashatsi bwubushakashatsi bwa siyansi, urukurikirane rwa R-ROFxxxxT rushobora guha abakoresha ibimenyetso byizewe, byoroshye, kandi birwanya cyane kwivanga ibimenyetso byokwirakwiza kure.

RF hejuru ya fibre Ibisobanuro

Urukurikirane R-ROFxxxxTRF hejuru ya fibre Ihuzaanalog Broadband optique transceiver ihuza ni fibre optique ya kure yoherejwe muburyo bwihariye bwo gupima igihe nyacyo cya DC kugeza 1GHz ibimenyetso byamashanyarazi mubidukikije bigoye bya electronique. Module yohereza iranga 1 MΩ / 50 Ω BNC yinjiza, ishobora guhuzwa nibikoresho bitandukanye byunvikana (probe iriho ubu, voltage nini cyane cyangwa ibikoresho byihariye byo gupima inshuro nyinshi). Mu guhererekanya module, ibimenyetso byamashanyarazi byinjijwe byahinduwe kandi bihinduka mubimenyetso bya optique, hanyuma byoherezwa kubakira byanyuze muburyo bumwe bwa optique fibre. Module yakira ihindura ibimenyetso bya optique isubira mubimenyetso byamashanyarazi. Ikwirakwizwa rya signal ya optique igengwa nuburyo bwikora kugirango igumane imikorere ihamye kandi ihoraho, idatewe nigihombo cya optique. Byombi transceiver module ishyigikira amashanyarazi ya batiri no kugenzura kure. Module yohereza optique ikubiyemo kandi imiterere ihuza n'imihindagurikire y'ikirere (1: 1/10: 1/100: 1) kugirango uhindure urwego rwakiriwe kugirango uhindure urwego rugaragara. Mubyongeyeho, mugihe igikoresho kidakoreshwa, kirashobora kwinjizwa kure muburyo buke bwo guhagarara kugirango ubike ingufu za bateri, kandi urumuri rwa LED rwerekana imikorere.

Ibiranga ibicuruzwa

Umuyoboro mugari wa DC-500 MHZ / DC-1 GHZ birashoboka

Indishyi zijyanye no guhuza ibicuruzwa

Inyungu irashobora guhinduka kandi ibyinjijwe bigenda neza

Gushyigikira kugenzura kure kandi ikoreshwa na bateri, bigatuma byoroha gukoreshwa hanze
