Isingeniso esifushane ku-I-Laser Yokushintshashintsha Okuqondile
I-Laser Yokushintshashintsha Okuqondile (I-DML Laser) ifinyelela ukuguqulwa kwamandla okukhanya ngokulawula ngqo amandla okushayela kwe-laser. I-laser ye-DML inezinzuzo zesakhiwo esilula, izindleko eziphansi, kanye nokuhlanganiswa okulula, futhi isetshenziswa kakhulu ezimweni zokuxhumana zebanga elifushane ngebanga lokudlulisa ≤ 10km, njenge-5G fronthaul kanye ne-data centre interconnection (100m-10km).
Esikhathini samanje sokuthuthuka kwezobuchwepheshe okusheshayo, isidingo sama-laser asebenza kahle siyakhula emikhakheni eminingi. Kungakhathaliseki ukuthi kulandelwa ukudluliselwa kwesignali okusebenzayo nokuzinzile noma ubuchwepheshe bokuzwela okunembile obudingayo, i-laser enhle kakhulu ibalulekile. Namuhla, sizokwethula umkhiqizo osindayo ongahlangabezana nezidingo eziningi eziyinkimbinkimbi - i-ROF-DML series 3GHz Direct Modulation Laser module. Ihlanganisa ngobuhlakani i-laser, isekethe yomshayeli, i-cooler eyakhelwe ngaphakathi, kanye nesekethe yokulawula izinga lokushisa, futhi lo mklamo ohlanganiswe kakhulu uthuthukisa kakhulu ukusebenza okuphelele. I-bandwidth yayo yokuguquguquka ingafinyelela ku-50KHz kuya ku-3GHz, idinga kuphela ukunikezwa kwamandla kwe-DC+5V. Isakhiwo sincane kakhulu futhi samukela ukupakishwa kwemodyuli. Akukhona nje kuphela ukuthi ukuzinza kwemodi kuhle kakhulu, kodwa umsindo wokuqina ohlobene uphansi, futhi amandla okukhanya okukhiphayo nawo azinzile kakhulu. Nge-bandwidth yayo ephezulu kanye nezici zokuguquguquka kwesignali ye-RF ezwela kakhulu, ngokungangabazeki iba yisinqumo esingcono kakhulu semithombo yokukhanya ye-analog RF signal direct modulation. Uyafuna ukwazi ukuthi ikhanya kanjani ezinhlelweni ezisebenzayo? Woza uzohlola ngokujulile nathi.
Imojula ye-DML yochungechunge lwe-3GHz Direct Modulation Laser ihlanganisa i-laser, isekethe yomshayeli, i-cooler eyakhelwe ngaphakathi, kanye nesekethe yokulawula izinga lokushisa; Lo mthombo wokukhanya une-bandwidth yokuguquguquka engu-3GHz, ukuzinza kwemodi okuhle kakhulu, umsindo ophansi wokuqina, kanye nokuzinza kwamandla okukhipha okuhle. Izici zokuguquguquka kwesignali ye-RF ephezulu kanye nokuzwela okuphezulu kwenza imikhiqizo ye-laser ye-ROF DML ibe yisinqumo esingcono kakhulu sesignali ye-analog RFimithombo yokukhanya yokuguquguquka okuqondile.
Izici zomkhiqizo: Ububanzi bokuguquguquka kwe-50KHz ~ 3GHz; Isekethe yokulawula izinga lokushisa eyakhelwe ngaphakathi; Isakhiwo esincane, ukupakishwa kwemodyuli enogesi we-DC + 5V
Izindawo zokusetshenziswa: Ukulingisa izixhumanisi zokudlulisa isignali ye-RF; Ukudluliselwa kwewashi; Umthombo wokukhanya kwembewu; Umthumeli wesignali ye-analog yekhebula le-TV
