GWR1000M CATV MiniNode

GWR1000M Optical MiniNode muaj ib qho chaw nres nkoj RF nrog rau pem hauv ntej txoj kev analog TV, DVB-C thiab CMTS DS cov teeb liab thiab cov kab hluav taws xob sab saud modem teeb liab ntawm hom tsis tu ncua lossis tawg dhau ntawm ib qho Bi-directional fiber lossis ob fibers. Nrog rau sab hauv tsev aluminium tuag-cam khwb cia vaj tse, GWR1000M yog qhov zoo tshaj plaws rau cov khoom siv fiber ntau rau hauv thaj chaw (FTTP), fiber ntau rau hauv pem teb (FTTF) lossis fiber ntau rau lub tsev (FTTB) daim ntawv thov ntawm CATV thiab internet networks. GWR1000M node muab ib qho RF tso zis mus txog 1.2 GHz (1218MHz) uas txhawb nqa ob peb lub TV terminals ncaj qha lossis tsav MDU amplifier hauv coaxial cable network.

GWR1000M node yog qhov zoo tagnrho rau cov ntawv thov ceev: MDU, tsev kawm qib siab, tsev kho mob thiab chaw ua lag luam. Nrog 20dBmV RF tso zis ntawm AGC hom, GWR1000M mininode tuav cov chaw tsim khoom me me yooj yim. Rov qab txoj kev transmitter tuaj yeem yog 1310nm lossis 1550nm ntawm 2^ndfiber chaw nres nkoj, nyob ntawm seb qhov system xav tau. Kev xaiv WDM thev naus laus zis tso cai rau ob txoj haujlwm ua haujlwm ntawm ib qho fiber ntau. CWDM rov qab txoj kev kho qhov muag wavelengths muaj los ua ke ntau ob txoj kev ntawm ib qho fiber ntau.

Raws li qhov chaw kho qhov muag sab hauv tsev, GWR1000M tuaj yeem ntsia tau rau ntawm phab ntsa los ntawm cov ntsia hlau lossis ntawm lub rooj. Nws tau tsim 6KV surge tiv thaiv ntawm txhua qhov chaw RF.

GWR1000M muaj ib qhov -20dB kuaj chaw nres nkoj, yooj yim saib xyuas txoj kev ua haujlwm rau pem hauv ntej thiab rov qab RF teeb liab.

GWR1000M tuaj yeem siv tau ntawm qhov chaw nres nkoj RF ywj pheej nrog lub chaw taws teeb 15V DC fais fab adapter, uas tso cai rau DC voltage poob qis dua 30 meter RG6 cable ntev. GWR1000M kuj tuaj yeem siv tau ntawm RF tso zis chaw nres nkoj.
