GWR1200 CATV Optical Node
Product Description
GWR1200 Optical Node muaj sab nraum zoov tuag-cam khwb cia txhuas vaj tse tso tawm rau pem hauv ntej txoj hauv kev analog TV, DVB-C thiab CMTS DS cov teeb liab thiab xa cov kab hluav taws xob hluav taws xob modem teeb liab ntawm hom tsis tu ncua lossis tawg dhau ntawm ib qho Bi-directional fiber lossis 2nd fiber. Lawv yog cov zoo tagnrho rau cov qib siab fiber ntau rau qhov chaw (FTTP) thiab fiber ntau rau lub tsev (FTTB) daim ntawv thov ntawm CATV thiab internet networks. GWR1200 node muab lub siab RF tso zis mus txog 1.2 GHz (1218MHz) uas yuav txo lossis tshem tawm qhov xav tau ntawm lub suab nrov tom qab hauv lub network.
GWR1200 node yog qhov zoo tagnrho rau cov ntawv thov ceev: MDU, tsev kawm qib siab, tsev kho mob thiab chaw ua lag luam. GWR1200 boasts 50dBmV tso zis uas tswj txhua qhov chaw tsim khoom loj. Rov qab txoj kev transmitter tuaj yeem yog 1310nm lossis 1550nm nyob ntawm qhov system yuav tsum tau ua. Kev xaiv WDM thev naus laus zis tso cai rau ob txoj haujlwm ua haujlwm ntawm ib qho fiber ntau. CWDM transmitters tau muab los ua ke ntau ob txoj kev ntawm ib qho fiber ntau.
Raws li qhov chaw kho qhov muag sab nraum zoov, GWR1200 tau tsim 4KV surge tiv thaiv ntawm txhua qhov chaw RF.
GWR1200 rov qab txoj kev transmitter tuaj yeem teeb tsa ntawm hom tawg kom txo cov suab nrov rov qab. Cov cuab yeej siv ib leeg fiber ntau thiab tau txais cov cim qis qis ntawm 1550nm thiab xa rov qab tuaj yeem raug txiav txim raws li 1310nm lossis 1610nm lossis CWDM wavelengthes nyob ntawm qhov xav tau ntawm lub cev. Raws li ib tug RFOG ntaus ntawv nws yog sib xws nrog DOCSIS® thiab tag nrho cov legacy HFC back office functionality.
