1550nm Yekunze Optical Transmitter
Iyi nhevedzano yemukati-modulated transmitter inoita RF-to-optical siginecha shanduko mu1550nm yekufambisa link.
1U 19 'yakajairwa kesi ine liquid crystal kuratidza (LCD/VFD) pamberi pepaneru;
Frequency bandwidth: 47-750 / 862MHz;
Simba rekubuda kubva ku4 kusvika ku24mw;
Advanced pre-distortion correction circuit;
AGC/MGC;
Automatic power control (APC) uye Automatic tembiricha yekudzora (ATC) dunhu.
Feature Ose ari maviri ekunze modulator uye laser anounzwa kubva kuUnited States kana Japan.
Yakakwana pre-distortion circuit inovimbisa yakanakisa CTB neCSO kana CNR iri pakakwirira.
Yakakwana SBS inodzvinyirira dunhu uye inogadziriswa SBS mu13, 16, 18, inokodzera mhando dzakasiyana dzeCATV net.
AGC kutonga.
Internal kaviri simba iro rinogona kuchinjwa otomatiki.
Automatic shell tembiricha control.
Yemukati microprocessor software ine basa rekutarisa laser, parameter kuratidza, kukanganisa yambiro, net manejimendi zvichingodaro.Kana iyo parameter yekushanda yelaser yabuda kunze kweiyo yakagadziriswa kukosha kwesoftware, muchina unozoyambira.
Iyo transmitter inopa RJ45 uye RS232 yakajairika interface yekubatanidza komputa uye yekutarisa.
