Chiyambi chachidule chaLaser Yosinthira Molunjika

Laser Yowongolera Molunjika (Laser ya DML() imakwaniritsa kusintha kwa mphamvu ya kuwala mwa kuwongolera mwachindunji mphamvu yoyendetsera ya laser. Laser ya DML ili ndi ubwino wa kapangidwe kosavuta, mtengo wotsika, komanso kuphatikiza kosavuta, ndipo imagwiritsidwa ntchito makamaka pazochitika zolumikizirana zazifupi ndi mtunda wotumizira ≤ 10km, monga 5G fronthaul ndi data center interconnection (100m-10km).

Munthawi ino ya chitukuko chaukadaulo mwachangu, kufunikira kwa ma laser apamwamba kukuchulukirachulukira m'magawo ambiri. Kaya kutsata kutumiza ma signal kogwira mtima komanso kokhazikika kapena ukadaulo wofunikira wozindikira molondola, laser yabwino kwambiri ndiyofunikira. Lero, tikupereka chinthu cholemera chomwe chingakwaniritse zosowa zambiri zovuta - module ya ROF-DML series 3GHz Direct Modulation Laser. Imaphatikiza mwanzeru laser, driver circuit, built-in cooler, ndi temperature control circuit, ndipo kapangidwe kameneka kophatikizana kwambiri kamathandizira kwambiri magwiridwe antchito onse. Bandwidth yake yosinthira imatha kufika 50KHz mpaka 3GHz, imafuna mphamvu ya DC+5V yokha. Kapangidwe kake ndi kakang'ono kwambiri ndipo kamagwiritsa ntchito ma module packaging. Sikuti kukhazikika kwa mode kokha ndikwabwino, komanso phokoso lamphamvu ndi lochepa, ndipo mphamvu yotulutsa yowunikira nayonso ndi yokhazikika kwambiri. Ndi mawonekedwe ake apamwamba a bandwidth komanso mawonekedwe a RF signal modulation, mosakayikira imakhala chisankho chabwino kwambiri cha magwero a kuwala a analog RF signal direct modulation. Kodi mukufuna kudziwa momwe imagwirira ntchito moyenera? Bwerani mudzafufuze mozama nafe.

Gawo la DML la 3GHz Direct Modulation Laser limaphatikiza laser, driver circuit, built-in cooler, ndi temperature control circuit; Gwero la kuwala ili lili ndi modulation bandwidth ya 3GHz, mode stability yabwino kwambiri, low relative intensity phokoso, komanso output power stability yabwino. Ma high bandwidth ndi high sensitivity RF signal modulation makhalidwe a ROF DML laser products kukhala chisankho chabwino kwambiri cha analog RF signalmagwero a kuwala kolunjika.

Zinthu zomwe zili mu malonda: Kusinthasintha kwa mphamvu ya 50KHz ~ 3GHz; Firiji yomangidwa mkati ndi dera lowongolera kutentha; Kapangidwe kakang'ono, ma phukusi a module okhala ndi magetsi a DC + 5V
Malo ogwiritsira ntchito: Kuyerekeza maulalo otumizira chizindikiro cha RF; Kutumiza kwa wotchi; Gwero la kuwala kwa mbewu; Chotumizira chizindikiro cha analogi cha TV ya chingwe
