GWR3300 Quad Return Path receiver
Tlhaloso ea Sehlahisoa
GWR3300 rack Mount Return Receiver e etselitsoe ho amohela lets'oao la ho khutla la CATV. Ka har'a rack ea 19 ”1RU, ho na le li-receiver tsa optical tse 4 tse ikemetseng, tse amohelang mats'oao a optical a tsoang ho node ea rona ea optical haeba ho na le fiber ho ea mohahong kapa marang-rang a mane a PON haeba fiber e ea lapeng. Moamoheli e mong le e mong o na le PIN diode ea lerata e tlase, preamplifier ea GaAs, setlhola se tlase sa band pass le amplifier ea boemo bo holimo ea RF, e fanang ka boemo ba tlhahiso ea 45dBmV karolong e ka morao ea 19” 1RU. PIN diode e ts'ehetsa 1260nm ~ 1650nm optical wavelength, ho kenyelletsa le 1310nm e tsebahalang, 1550nm le liteishene tse ling tsa CWDM. Ka phanele e ka pele, ho na le boema-kepe bo le bong ba -20dB RF le attenuator e le 'ngoe e sa fetoheng bakeng sa moamoheli e mong le e mong, e nolofalletsang ho hlophisoa ha tsela e' ngoe le e 'ngoe ea ho khutla ea RF. Bandwidth ea moamoheli e mong le e mong oa tsela ea ho khutla ke 5MHz ~ 204MHz, e tsamaisanang le node ea optical RF band e arohaneng ea 42/54MHz, 65/85MHz, 85/102MHz, 204/258MHz, e tšehetsang Docsis 2.0, Docsis 3.0 le modem ea cable ea Docsis 3.1 holimo. Ka mantsoe a mang, GWR3300 e ka sebetsana le matšoao ohle a CATV a holimo, ho sa tsotellehe li-node tsa optical kapa li-micronodes tsa RFoG.
Ntle le mekhoa e mene e ikemetseng ea ho khutlisa liphetho tsa RF, ho na le boema-kepe bo le bong ba RF bo kopanyang liphetho tse 'ne tsa moamoheli joalo ka tlhahiso e le' ngoe ea RF, e loketseng khokahano ea boema-kepe ba CMTS US.
Ka ts'ebetso e phahameng ea photodiode le amplifier e nyalisitsoeng, GWR3300 e fana ka sehlopha se hloekileng sa ho khutla bakeng sa matshwao a phahamisang a Cable Modem. Letšoao la matla a optical le boema-kepe ba tlhahlobo ea RF phanele e ka pele e ka bonts'a boemo ba moamoheli.
Likarolo tse ling:
• 1550nm/1310nm dual wavelength.
• RPR e ikemetseng e 4 ho rack e le 'ngoe ea 19” 1U e tloaelehileng.
• Lerata le tlaase, photodiode e phahameng ea linearity.
• 5- 204 MHz RF Bandwidth.
• Lisefa tse peli tsa li-band pass ho theola lerata le holimo.
• Tokiso ea tlhahiso le tlhahlobo ea -20dB RF e fumaneha ka pele phanele.
