GWR3300 Quad ụzọ nloghachi
Nkọwa ngwaahịa
Emebere GWR3300 rack mount back reps nnata maka nnabata CATV ime ụlọ. N'ime 19 "1RU rack, enwere ndị na-anata ihe nleba anya nke 4 nwere onwe ha, nke na-enweta akara ngosi anya ụzọ nloghachi site na oghere anya anyị ma ọ bụrụ na fiber na ụlọ ma ọ bụ netwọọdụ PON anọ ma ọ bụrụ na eriri na-abanye n'ụlọ. Onye ọ bụla nnata nwere arụnyere na obere mkpọtụ PIN diode, GaAs preamplifier, obere band pass filter na elu mmepụta ọkwa RF amplifier, na-enye ihe ruru 45dBmV ọkwa mmepụta na 19 "1RU azụ panel. PIN diode na-akwado 1260nm ~ 1650nm anya wavelength, gụnyere 1310nm na-ewu ewu, 1550nm na ọwa CWDM ndị ọzọ. Na n'ihu panel, e nwere otu -20dB RF ule ọdụ ụgbọ mmiri na otu na-aga n'ihu na-agbanwe agbanwe attenuator maka onye ọ bụla nnata, na-enyere mfe nhazi nke ọ bụla nloghachi ụzọ RF mmepụta larịị. The bandwit nke ọ bụla nloghachi ụzọ nnata bụ 5MHz ~ 204MHz, dakọtara ngwa anya ọnụ RF band nkewa nke 42/54MHz, 65/85MHz, 85/102MHz, 204/258MHz, na-akwado Docsis 2.0, Docsis 3.0 na Docsis 3.1 cable signals modem elu RF. N'ikwu ya n'ụzọ ọzọ, GWR3300 nwere ike ịnagide akara ngosi CATV niile, n'agbanyeghị oghere anya ma ọ bụ RFoG micronodes.
Ewezuga ụzọ nlọghachi azụ anọ nwere onwe ya, enwere otu ọdụ ụgbọ mmiri RF na-ejikọta nsonaazụ nnata anọ dị ka otu mmepụta RF, nke dabara na njikọ ọdụ ụgbọ mmiri CMTS US.
Site na fotodiode dị elu na ngwakọ ngwakọ, GWR3300 na-enye eriri ụzọ nloghachi dị ọcha maka akara mgbago elu-Modem USB. Ngosipụta ike anya na ọdụ ụgbọ mmiri ule RF dị n'ihu panel nwere ike igosi ọkwa nnata.
Atụmatụ ndị ọzọ:
• 1550nm / 1310nm dual wavelength.
• 4 RPR nọọrọ onwe ya n'otu rack ọkọlọtọ 19" 1U.
• mkpọtụ dị ala, fotodiode linearity dị elu.
• bandwit 5-204 MHz RF.
• Ihe nzacha bandwit abụọ iji mebie mkpọtụ na-ebuli elu.
• Ndozi mmepụta na -20dB RF ule dị na ihu panel.
