Product Description

GWT3500 yog qhov ncaj qha ntawm kev ua kom ncaj qha 1550nm DFB transmitter rau analog TV hauv zos Fiber ntau lub chaw faib khoom thiab cov TV cim ntsuas hluav taws xob ntev. Lub transmitter siv high linearity DFB laser, RF fais fab digital tsis siv neeg txheej txheem txheej txheem, nrog rau RF pre-distortion circuit tsim los ntawm Greatway Technology. Lub built-in microprocessor saib xyuas lub transmitter ua hauj lwm raws li txoj cai thiab cia li ua kom lub optimistic kev ua tau zoo. GWT3500 yog qhov zoo tagnrho rau analog TV fiber ntau faib hauv 20Km thiab QAM TV teeb liab kis tau tus mob ntev li ntawm 100Km.

Fiber tau qhia txog kev xa tawm CATV RF hauv xyoo 1990 vim nws qhov qis qis thiab yuav luag tsis muaj kev txwv bandwidth. RF rau fiber ntau converter yog cov khoom tseem ceeb tshaj plaws. Nrog lub suab nrov qis thiab microprocessor, tag nrho RF lub zog ntawm lub laser tuaj yeem raug teeb tsa kom raug, xyuas kom zoo tshaj qhov ntsuas qhov ntsuas qhov muag (OMI). Lub txias DFB laser nyob rau hauv lub transmitter ua kom ruaj khov DWDM optical wavelength rau kev tshaj tawm lossis tso cov kev pabcuam sib tham sib nqaim. Meanwhile txias DFB laser muaj zoo laser RIN (tus txheeb ze siv suab nrov) thiab ruaj khov laser tso zis zog. Ortel-Emcore siab linearity txias DFB laser thiab Greatway tsim tau raug pov thawj los ua ib qho kev ua tau zoo. GWT3500 optical transmitter tau dav siv los ntawm cov neeg siv khoom hauv North America, South America thiab Tuam Tshoj nrog kev ua tau zoo thiab ua pov thawj zoo.

Ua ke nrog Greatway siab lub zog kho qhov muag amplifier, GWT3500 transmitter tuaj yeem xa cov teeb liab TV zoo fiber ntau rau lub tsev lossis fiber ntau rau hauv tsev.
