Intshayelelo kwi-3GHz Directly Modular Laser

Intshayelelo kuI-Laser yeModular ethe ngqo ye-3GHz

Kule mihla yophuhliso olukhawulezayo lobuchwepheshe, imfuno yeeleser ezisebenzayo iyanda kwiindawo ezininzi. Nokuba kukulandela ukuhanjiswa kwesignali okusebenzayo nokuzinzileyo okanye ubuchwepheshe bokubona ngokuchanekileyo obufunekayo, ieleser egqwesileyo ibalulekile. Namhlanje, singathanda ukwazisa imveliso enzima enokuhlangabezana neemfuno ezininzi ezinzima - uthotho lweROF DML 3GHzI-Laser yeModular ngqoimodyuli. Idibanisa ngobuchule i-laser, 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 kwemodyuli. Ayisiyonto nje yokuba 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.

1. Intshayelelo

I-3GHzIleyiza ye-DMLuthotho yimodyuli edibanisa ii-laser, iisekethe zomqhubi, iifriji, kunye neesekethe zokulawula ubushushu. Isici sayo esiphambili kukusetyenziswa kwe-signal direct modulation yangaphandle, ene-bandwidth ebanzi ye-modulation ye-50KHz ukuya kwi-3GHz, kwaye ifuna kuphela umbane we-DC+5V. Uyilo lwayo lujolise ekuboneleleni nge-bandwidth ephezulu kunye novakalelo oluphezulu.umthombo wokukhanya we-modulation ngqoisisombululo sokulinganisa imiqondiso ye-RF (i-radio frequency).

2. Iimpawu eziphambili kunye neenzuzo

I-bandwidth ephezulu: Ububanzi bexesha lokuguquguquka ukusuka kwi-50KHz ukuya kwi-3GHz.

Ukuhlanganiswa okuphezulu kunye nozinzo: Ukupholisa okwakhelwe ngaphakathi kunye nolawulo lobushushu kuqinisekisa amandla okukhanya azinzileyo (uzinzo oluqhelekileyo± 0.05 dB/8h), imo ezinzileyo, kunye nengxolo ephantsi yoxinzelelo.

Incinci kwaye kulula ukuyisebenzisa: ukupakisha okunemodyuli, ubungakanani obuyi-73x60x19.5 mm, umbane omnye.

Ukusebenza kakuhle kakhulu: yenzelwe ngokukodwa iimpawu ze-analog, ezinobuntununtunu obuphezulu.

3. Iiparameter zokusebenza eziphambili

Ububanzi bomda obuphakathi: Bubonelela ngeendlela ezahlukeneyo ze-1310nm okanye i-1550nm.

Amandla okuphuma kwe-optical: Kukho iinkcukacha ezimbini onokukhetha kuzo: 5mW kunye ne-10mW.

I-bandwidth yokuguqula (@ 3dB): ukuya kuthi ga kwi-3GHz.

Ujongano: Igalelo le-RF sisixhumi se-SMA-F esine-50 eqhelekileyoΩ Impedance ehambelanayo; Isiphumo se-optical singakhethwa kwizihlanganisi ezifana ne-FC/PC okanye i-FC/APC, kwaye ifayibha ingakhethwa kwi-single-mode (SMF) okanye kwi-polarization maintaining (PMF).

Iimeko zokusebenza: Ubushushu bokusebenza -10℃ukuya kuma-60℃, amandla aphezulu okufaka i-RF angama-20dBm.

4. IiNdawo zokufaka izicelo

Le mveliso ijoliswe ikakhulu kwiimeko ezifuna ukuhanjiswa kwesignali ye-analog esemgangathweni ophezulu, kuquka: amakhonkco okuhanjiswa kwesignali ye-analog RF; ukuhanjiswa kwewotshi; umthombo wokukhanya kwembewu;

Umthumeli wesignali ye-analog kwiTV yekhebula (iTV yekhebula).
