Chiyambi cha 3GHz Directly Modular Laser

Chiyambi chaLaser Yokhazikika ya 3GHz Mwachindunji

Munthawi ino ya chitukuko cha ukadaulo mwachangu, kufunikira kwa ma laser ogwira ntchito kwambiri kukuwonjezeka m'magawo ambiri. Kaya kutsata kutumiza ma signal kogwira mtima komanso kokhazikika kapena ukadaulo wofunikira wowunikira molondola, laser yabwino kwambiri ndiyofunikira. Masiku ano, tikufuna kuyambitsa chinthu cholemera chomwe chingakwaniritse zosowa zambiri zovuta - mndandanda wa ROF DML 3GHzLaser Yokhazikika Mwachindunjimodule. Imaphatikiza mwanzeru laser, driver circuit, cooler yomangidwa mkati, ndi temperature control circuit, ndipo kapangidwe kake 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 packing. 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 sensitivity high 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.

1. Chiyambi

3GHzLaza ya DMLMndandanda ndi gawo lomwe limaphatikiza ma laser, ma driver circuits, mafiriji, ndi ma temperature control circuits. Mbali yake yayikulu ndikugwiritsa ntchito external signal direct modulation, yokhala ndi bandwidth yayikulu ya 50KHz mpaka 3GHz, ndipo imangofunika DC+5V power supply yokha. Kapangidwe kake cholinga chake ndi kupereka bandwidth yayikulu komanso kukhudzidwa kwakukulu.gwero la kuwala kolunjikanjira yothetsera zizindikiro za RF (mafupipafupi a wailesi).

2. Makhalidwe ndi ubwino wapakati

Kutalika kwa liwiro: Ma frequency a modulation amachokera pa 50KHz mpaka 3GHz.

Kuphatikiza kwakukulu ndi kukhazikika: Kuziziritsa komangidwa mkati ndi kuwongolera kutentha kumaonetsetsa kuti mphamvu yotulutsa yokhazikika (kukhazikika kwachizolowezi)± 0.05 dB/8h), mawonekedwe okhazikika, komanso phokoso lochepa.

Yaing'ono komanso yosavuta kugwiritsa ntchito: ma CD opangidwa modular, kukula kwake ndi 73x60x19.5 mm, magetsi amodzi.

Kugwira ntchito bwino kwambiri: kopangidwira makamaka zizindikiro za analog, zokhala ndi mphamvu zambiri.

3. Magawo ofunikira a magwiridwe antchito

Kutalika kwa mafunde pakati: Kumapereka zosankha za 1310nm kapena 1550nm.

Mphamvu yotulutsa kuwala: Pali zinthu ziwiri zomwe mungasankhe: 5mW ndi 10mW.

Bandwidth yosinthira (@ 3dB): mpaka 3GHz.

Chiyankhulo: Cholowera cha RF ndi cholumikizira cha SMA-F chokhala ndi 50 yokhazikikaΩ Kugwirizana kwa impedance; Chotulutsa cha kuwala chingasankhidwe kuchokera ku zolumikizira monga FC/PC kapena FC/APC, ndipo ulusi ungasankhidwe kuchokera ku single-mode (SMF) kapena polarization maintaining (PMF).

Mikhalidwe Yogwirira Ntchito: Kutentha kwa ntchito -10℃mpaka 60℃, mphamvu yayikulu kwambiri yolowera ya RF ya 20dBm.

4. Minda Yogwiritsira Ntchito

Chogulitsachi chimayang'ana kwambiri zochitika zomwe zimafuna kutumiza chizindikiro cha analog chapamwamba kwambiri, kuphatikizapo: maulalo otumizira chizindikiro cha analog RF; Kutumiza kwa wotchi; Gwero la kuwala kwa mbewu;

Chotumizira chizindikiro cha analogi cha TV ya chingwe (TV ya chingwe).
