Intshayelelo emfutshane kuI-Laser yoGuqulelo oluQokeleyo
I-Laser yokuguqula ngokuthe ngqo (I-DML Laser) ifezekisa ukuguqulwa kwamandla okukhanya ngokulawula ngokuthe ngqo umsinga oqhubayo welaser. Ilaser yeDML ineengenelo zesakhiwo esilula, iindleko eziphantsi, kunye nokudibanisa okulula, kwaye isetyenziswa kakhulu kwiimeko zonxibelelwano ezikufutshane kunye nomgama wokudlulisela ≤ 10km, ezifana ne-5G fronthaul kunye noqhagamshelwano lweziko ledatha (100m-10km).
Kule mihla yophuhliso lobuchwepheshe olukhawulezayo, imfuno yeelaser ezisebenzayo kakhulu iyanda kwiindawo ezininzi. Nokuba kulandelwa ukuhanjiswa kwesignali okusebenzayo nokuzinzileyo okanye ubuchwepheshe bokubona ngokuchanekileyo obufunekayo, ilaser egqwesileyo ibalulekile. Namhlanje, siza kwazisa imveliso enzima enokuhlangabezana neemfuno ezininzi ezinzima - imodyuli ye-ROF-DML series 3GHz Direct Modulation Laser. Idibanisa ngobuchule ilaser, isekethe yomqhubi, i-cooler eyakhelwe ngaphakathi, kunye nesekethe yokulawula ubushushu, kwaye olu yilo ludibeneyo kakhulu luphucula kakhulu ukusebenza ngokubanzi. I-bandwidth yayo ye-modulation inokufikelela kwi-50KHz ukuya kwi-3GHz, ifuna kuphela umbane we-DC+5V. Isakhiwo sincinci kakhulu kwaye samkela ukupakisha imodyuli. Ayipheleli nje ekubeni uzinzo lwemowudi lubalaseleyo, kodwa ingxolo yobukhulu obuhambelanayo iphantsi, kwaye amandla okukhanya aphumayo nawo azinzile kakhulu. Ngeempawu zayo ze-bandwidth ephezulu kunye novakalelo oluphezulu lwe-RF signal modulation, ngokungathandabuzekiyo iba lolona khetho lubalaseleyo kwimithombo yokukhanya ye-analog RF signal modulation direct. Ngaba ufuna ukwazi ukuba ikhanya njani kwizicelo ezisebenzayo? Yiza uze uhlolisise nzulu nathi.
Imodyuli yeLaser ye-DML series 3GHz Direct Modulation idibanisa i-laser, isekethe yomqhubi, i-cooler eyakhelwe ngaphakathi, kunye nesekethe yokulawula ubushushu; Lo mthombo wokukhanya une-bandwidth ye-modulation ye-3GHz, uzinzo oluhle kakhulu lwemowudi, ingxolo ephantsi yoxinzelelo, kunye nozinzo oluhle lwamandla okukhupha. Iimpawu ze-bandwidth ephezulu kunye novakalelo oluphezulu lwesignali ye-RF zenza iimveliso ze-laser ye-ROF DML zibe lolona khetho lufanelekileyo lwesignali ye-analog RFimithombo yokukhanya yemodulation ngqo.
Iimpawu zemveliso: I-bandwidth yokuguquguquka kwe-50KHz ~ 3GHz; Ifriji eyakhelwe ngaphakathi kunye nesekethe yokulawula ubushushu; Ulwakhiwo oluncinci, upakisho lwemodyuli olune-DC + 5V power supply
Iindawo zokusetyenziswa: Ukulinganisa amakhonkco okuhambisa isignali ye-RF; Ukuhanjiswa kwewotshi; Umthombo wokukhanya kwembewu; Umthumeli wesignali ye-analog ye-Cable TV
