GWR3300 Quad Return Path receiver
Product Description
GWR3300 khib mount rov qab txoj kev receiver yog tsim los rau sab hauv tsev CATV rov qab teeb liab tau txais.Nyob rau hauv 19 "1RU khib, muaj ntau tshaj 4 txoj kev ywj pheej rov qab kho qhov muag receivers, uas tau txais txoj kev rov qab kho qhov muag teeb liab los ntawm peb cov optical nodes nyob rau hauv cov ntaub ntawv ntawm fiber ntau rau lub tsev los yog plaub PON network nyob rau hauv cov ntaub ntawv ntawm fiber rau lub tsev.Txhua tus txais muaj lub suab nrov PIN diode, GaAs preamplifier, low band pass lim thiab siab tso zis theem RF amplifier, muab txog li 45dBmV tso zis theem ntawm 19 "1RU rear vaj huam sib luag.Tus PIN diode txhawb 1260nm ~ 1650nm optical wavelength, suav nrog cov nrov 1310nm, 1550nm thiab lwm yam CWDM raws.Nyob rau pem hauv ntej vaj huam sib luag, muaj ib tug -20dB RF xeem chaw nres nkoj thiab ib tug nruam adjustable attenuator rau txhua tus txais, ua kom yooj yim teeb tsa ntawm txhua txoj kev rov qab RF tso zis theem.Qhov bandwidth ntawm txhua qhov kev xa rov qab tau txais yog 5MHz ~ 204MHz, sib piv qhov kho qhov muag ntawm RF band splitting ntawm 42/54MHz, 65/85MHz, 85/102MHz, 204/258MHz, txhawb Docsis 2.0, Docsis 3.0 thiab Docsis 3.1 RF cable modem.Hauv lwm lo lus, GWR3300 tuaj yeem cuam tshuam nrog tag nrho CATV cov kab hluav taws xob sab saud, tsis hais qhov kho qhov muag lossis RFoG micronodes.
Dhau li ntawm plaub txoj kev ywj pheej rov qab RF tso tawm, muaj ib qho RF chaw nres nkoj sib txuas plaub qhov kev tso tawm tau txais los ua ib qho RF tso zis, uas yooj yim rau CMTS US chaw nres nkoj txuas.
Nrog rau kev ua haujlwm siab photodiode thiab hybrid amplifier, GWR3300 muab cov kab rov qab huv rau Cable Modem up-streaming signals.Qhov taw qhia lub hwj chim kho qhov muag thiab RF xeem chaw nres nkoj ntawm lub vaj huam sib luag pem hauv ntej tuaj yeem qhia tus neeg txais cov xwm txheej.
Lwm yam nta:
• 1550nm / 1310nm dual wavelength.
• 4 ywj siab RPR hauv ib qho 19 "1U txheem khib.
• Tsis tshua muaj suab nrov, siab linearity photodiode.
• 5- 204 MHz RF Bandwidth.
• Ob pawg hla cov lim dej kom txo qis lub suab nrov nrov.
• Tso zis hloov thiab -20dB RF xeem muaj nyob rau pem hauv ntej vaj huam sib luag.
