1550nm Sab nraud Optical Transmitter
Qhov no series sab hauv-modulated transmitter ua RF-rau-optical teeb liab hloov dua siab tshiab hauv 1550nm kis tau tus mob txuas.
1U 19 'cov ntaub ntawv txheem nrog cov kua siv lead ua kua (LCD / VFD) nyob rau hauv pem hauv ntej vaj huam sib luag;
Zaus bandwidth: 47-750 / 862MHz;
Cov zis hluav taws xob los ntawm 4 mus rau 24mw;
Advanced pre-distortion kho Circuit Court;
AGC/MGC;
Tsis siv neeg fais fab tswj (APC) thiab Tsis Siv Neeg Kub Tswj (ATC) Circuit Court.
Feature Ob qho tib si sab nraud modulator thiab laser yog imported los ntawm Tebchaws Meskas lossis Nyiv.
Zoo meej pre-distortion Circuit Court kom ntseeg tau qhov zoo tshaj plaws CTB thiab CSO thaum CNR nyob rau hauv highstandard.
Zoo meej SBS suppress Circuit Court thiab kho SBS hauv 13,16, 18, haum rau ntau hom CATV net.
AGC tswj.
Sab hauv ob lub zog uas tuaj yeem hloov pauv tau.
Tsis siv neeg lub plhaub kub tswj.
Internal microprocessor software muaj kev ua haujlwm ntawm laser xyuas, parameter zaub, ceeb toom txhaum, net tswj thiab lwm yam.Thaum qhov kev ua haujlwm tsis zoo ntawm lub laser tawm ntawm tus nqi ruaj khov ntawm cov software, lub tshuab yuav ceeb toom.
Lub transmitter muab RJ45 thiab RS232 tus qauv interface rau kev sib txuas ntawm lub computer thiab saib xyuas.
