Nhanganyaya ku3GHz Yakananga Modular Laser
Munguva ino yekukura kwetekinoroji nekukurumidza, kudiwa kwemalaser anoshanda zvakanyanya kuri kuwedzera munzvimbo dzakawanda. Kungave kutsvaga kutumira masaini kunoshanda uye kwakasimba kana tekinoroji inoda kunzwisisika, laser yakanaka yakakosha. Nhasi, tinoda kuunza chigadzirwa chinorema chinogona kusangana nezvinodiwa zvakawanda zvakaoma - ROF DML series 3GHzLaser yeModular zvakanangamodule. Inobatanidza neunyanzvi laser, driver circuit, built-in cooler, uye temperature control circuit, uye dhizaini iyi yakabatana zvikuru inowedzera kushanda kwese. bandwidth yayo ye modulation inogona kusvika 50KHz kusvika 3GHz, ichingoda DC+5V power supply chete. Chimiro chacho chakaoma zvikuru uye chinoshandisa module packaging. Haisi chete kuti mode stability yakanaka, asi ruzha rwakaderera, uye output optical power yakagadzikanawo. Ne high bandwidth yayo uye high sensitivity RF signal modulation characteristics, hapana mubvunzo kuti inova sarudzo yakanakisa yeanalog RF signal direct modulation light sources. Unoda kuziva kuti inopenya sei mumashandisirwo anoshanda? Uya unyatsoongorora nesu zvakadzama.
1. Nhanganyaya
Iyo 3GHzLaser yeDMLIyi module inobatanidza ma laser, ma driver circuits, mafiriji, uye ma temperature control circuits. Chinhu chikuru chayo kushandisa external signal direct modulation, ine wide modulation bandwidth ye50KHz kusvika 3GHz, uye inongoda DC+5V power supply chete. Dhizaini yayo ine chinangwa chekupa high bandwidth uye high sensitivity.mwenje wekuchinja kwakanangamhinduro yekutevedzera masaini eRF (radio frequency).
2. Zvinhu zvikuru uye zvakanakira
bandwidth yakakwirira: frequency yekuchinja inotangira pa50KHz kusvika pa3GHz.
Kubatanidzwa kwakanyanya uye kugadzikana: Kutonhodza kwakavakirwa mukati uye kudzora tembiricha kunovimbisa simba rakasimba rekuburitsa optical (kugadzikana kwakajairika)± 0.05 dB/8h), stable mode, uye ruzha rwakaderera.
Yakabatana uye iri nyore kushandisa: kurongedza kwemodular, saizi 73x60x19.5 mm, simba rimwe chete.
Kushanda kwakanaka kwazvo: kwakagadzirirwa zvakananga zviratidzo zveanalog, zvine kutaridzika kwakanyanya.
3. Zviyero zvekushanda zvakakosha
Hurefu hwepakati: Hunopa sarudzo dze1310nm kana 1550nm.
Simba remagetsi rinobuda: Pane zvinhu zviviri zvekusarudza kubva: 5mW uye 10mW.
Bandwidth yekuchinja (@ 3dB): kusvika ku3GHz.
Chinongedzo: Chinongedzo cheRF chinongedzo cheSMA-F chine mwero we50Ω kuenderana kweimpedance; Kubuda kwe optical kunogona kusarudzwa kubva kuma connectors akadai seFC/PC kana FC/APC, uye fiber inogona kusarudzwa kubva ku single-mode (SMF) kana polarization maintaining (PMF).
Mamiriro ekushanda: Tembiricha yekushanda -10℃kusvika 60℃, simba guru reRF rekupinda re20dBm.
4. Minda Yekushandisa
Chigadzirwa ichi chinonyanya kuitirwa mamiriro ezvinhu anoda kutapurirana kwechiratidzo cheanalog chemhando yepamusoro, kusanganisira: malink ekutapurirana kwechiratidzo cheRF cheanalog; kutapurirana kwewachi; Sosi yemwenje yembeu;
Chinotumira masaini eanalog eTV yetambo (TV yetambo).
