1550EA
1550EA SERIES ITU YESE C-BAND ACHIRIRA-INOGONA EXTERNAL MODULATION OPTICAL TRANSMITTER
Features
◆Hunhu hwepamusoro: yekutanga mbiri mbiri microwave innovative itsva tekinoroji, RF predistortion tekinoroji insure mumamiriro emhando CNR=53dB, system inogona kuwana yakakura CTB.CSO.SBS index.
◆ Flexibility: iyo modulator tekinoroji yekunze modulator inosimbisa CSO kuita zvakanakisa, inovandudza fiber optical simba repamusoro, kuwana kureba kureba kuchinjirwa.SBS: 13-19, OMI, ITU wavelength inogadziriswa, AGC/MGC inosarudzwa, shandisa kunetiweki yakasiyana.
◆Intuitive: Laser ndiyo inonyanya kudhura zvikamu zvemuchina, muchina wakagadzirirwa microprocessor monitors mamiriro ekushanda e laser, iyo panel LCD hwindo rinoratidza maitiro ekushanda.
◆Network type: Sarudza All-piece status monitoring transponder garandi kuti isangane nenyika yese uye ienderane neSCTE HMS standard, inogonesa network manejimendi yekutarisa kugona.(Plag in type power supply): tora aluminium profile plug mu type switch power supply, inogona kushanda pa85 265Vac City Network Voltage, Pamwe nesarudzo yeDC48V magetsi (kuchengetedzwa kunodiwa);chassis kutonhora otomatiki tembiricha kutonga.
