Yethula isisombululo esisha se-RF phezu kwe-fiber Link esingu-40GHz

Yethula okushaI-40GHz RF phezu kwefayibhaIsixazululo sesixhumanisi

Emkhakheni wokuxhumana nge-microwave, indlela yendabukoIsixhumanisi se-RF phezu kwefayibhaIsixazululo besilokhu sivinjelwa yizinkinga ezimbili ezinkulu: Izintambo ze-coaxial ezibizayo kanye nama-waveguides awakhulisi nje kuphela izindleko zokuthunyelwa, kodwa futhi abophe ngokuqinile ukudluliswa kwesignali ngebanga, kanye nokumbozwa kwebhendi yemvamisa kanye nokuqina nakho kunzima ukuhlangabezana nezidingo zezinhlelo zokusebenza ze-broadband. Sibhekene nalesi simo, siyajabula ukukuncoma - uchungechunge lwe-ROFBox 40GHz External Modulation Broadband Analog RF RF phezu kwe-fiber Link. Lokhu akuyona nje umkhiqizo; kuyiphepha lempendulo elihle kakhulu esilithumele ukuze lidlule imikhawulo yomzimba.

Lo mkhiqizo omusha usebenzisa ukudluliswa kwe-optical kwe-modulation yangaphandleI-RF phezu kwefayibhaIsixazululo sesixhumanisi, esisekela ukuguqulwa okungenakulahlekelwa kwezibonakaliso ze-RF ngaphakathi kobubanzi be-ultra-wideband obungu-1-40GHz. Sithatha indawo yemidiya yensimbi yendabuko ngezixhumanisi ze-optical fiber, siphula ngokuphelele imikhawulo ebonakalayo yebanga lokudlulisela.

Izinzuzo zayo eziyinhloko ziseku: ukuthembeka okuphezulu kwebhendi ephelele: Ukumbozwa kwebhendi ebanzi engu-1-40GHz, kuhlanganiswe nomklamo olungiselelwe kahle, oqinisekisa ukukhiqizwa kabusha okunembile kobukhulu besiginali kanye nesigaba; Ukweqa okusebenzayo kwezindleko: Gwema izintambo ze-coaxial ezibizayo kanye nezinhlangano ze-waveguide, kunciphisa izindleko zokuthunyelwa ngaphezu kuka-60%; Ukuphumelela kwamandla okulwa nokuphazamiseka:Ukudluliswa kwefayibha yokukhanyaimelana ngokwemvelo nokuphazamiseka kwe-electromagnetic, futhi ukuzinza kwesignali ezindaweni eziyinkimbinkimbi kuthuthukiswe kakhulu.

Kusukela ekudlulisweni kwesignali ekuxhumaneni okungenantambo okude kuya ekwabiweni okunembile kwezibonakaliso zesikhathi, bese kuba ukusetshenziswa okungokoqobo kwezinhlelo ze-telemetry kanye nemigqa yokulibaziseka, ingakwazi ukuzivumelanisa kahle, inikeze ukwesekwa okuqinile kwezimo ezahlukahlukene ze-microwave ye-broadband futhi ivule imingcele engenzeka yokuchaza kabusha izinhlelo zokusebenza ze-microwave ye-analog broadband.

Izici zomkhiqizo ze-40GHz RF phezu kwe-fiber Isixhumanisi:

I-bandwidth ephezulu iyatholakala kusukela ku-1 kuya ku-40GHz

Ukusabela kwe-RF okuhle kakhulu kanye nobubanzi obuguquguqukayo

Imodi yokusebenza esobala ngokuphelele, esebenza kumakhodi ahlukahlukene esignali, amazinga okuxhumana kanye nezinqubo zenethiwekhi

Ama-wavelength asebenzayo angakhethwa njengo-1550nm kanye no-1310nm

Ihlanganisa izifunda zokulawula amandla okuzenzakalelayo (i-APC) kanye nezifunda zokulawula izinga lokushisa okuzenzakalelayo (i-ATC).

Ifakwe i-laser esebenza kahle kakhulu kanye ne-optical amplification module ukuze kufezwe ukulungiswa kwenzuzo kanye nokulawula okuzenzakalelayo

I-amplifier ye-RF yomshayeli eyakhelwe ngaphakathi inganikeza ukuguquguquka okwengeziwe kwezinhlelo zokusebenza

Izinkambu zohlelo lokusebenza

I-antenna ekude

Ukuxhumana kwe-analog optical fiber okude

Ukuxhumana kwezempi ngamaza amathathu

Ukulandelela, Ukulawula kanye Nokulawula (TT&C)

Imigqa yokulibaziseka
