Zy-1550-Dm 1550nm Directly Modulated Optical Transmitter

ZY-1550-DM 1550nm Directly Modulated Optical Transmitter It is designed according to CATV standard. It modulates CATV RF amplitude signal into 1550nm optical signal and then transmits it to optical node in HFC network through single-mode optical fiber. The maximum compensation distance is up to 50km and high isolation between two RF inputs.  Application:It is mainly used for TV signal medium-sized network transmission and the distribution network with short distance, it can be amplified after stage.Features:*47~ 862Mhz ( customized 1000MHz).*Support optical AGC,Switchable to MGC.*International famous DFB laser, output wavelength is ITU standard selectable.*Built-in WDM and VOA Variable Optical Attenuator.*Standard network management interface, in line with SNMP network management protocol.*Hot backup dual power modules.Principle Diagram  :Other Optical Transmitter recommended: ZY-1550-EM  1550nm External Modulated Transmitter Features:* This 1550nm optical transmitter can be used in long-distance transmission.* Double microwave source SBS control,+13~+19dBm adjustable,0.5dB stepping.* Adopt USA original AOI DFB laser and LiNbO3 external modulator.* RF gain of AGC/MGC mode is optional and OMI can be optimized at spot.* Perfect RS232 communication interface & SNMP network management.* Hot backup dual power modules.      /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
