Node Optical GWR1200 CATV
Hōʻike huahana
Loaʻa i ka GWR1200 Optical Node kahi hale alumini make-cast waho e hoʻopuka ana i ke ala TV analog, DVB-C a me CMTS DS hōʻailona a me ka hoʻouna ʻana i nā hōʻailona modem cable upstream ma ke ʻano maʻamau a i ʻole ka ʻūhā ma luna o ka fiber Bi-directional hoʻokahi a i ʻole ka 2nd fiber. He kūpono lākou no ka fiber kiʻekiʻe i ka hale (FTTP) a me ka fiber i ka hale (FTTB) nā noi ma CATV a me nā pūnaewele pūnaewele. Hāʻawi ka GWR1200 node i kahi puka RF kiʻekiʻe a hiki i 1.2 GHz (1218MHz) e hōʻemi a hoʻopau paha i ka pono o ka post-node amplifier ma ka pūnaewele.
He kūpono ka node GWR1200 no nā noi haʻahaʻa kiʻekiʻe: MDU, nā kulanui, nā halemai a me nā paka ʻoihana. Hāʻawi ʻo GWR1200 i kahi hoʻopuka 50dBmV e lawelawe ana i kekahi ʻoihana nui. Hiki i ka transmitter ala hoʻi ke 1310nm a i ʻole 1550nm ma muli o nā koi ʻōnaehana. Hiki i ka ʻenehana WDM koho ke hana i nā hana ʻelua ma ka fiber hoʻokahi. Hāʻawi ʻia nā mea hoʻouna CWDM e hoʻohui i nā nodes ʻelua ala ma kahi fiber.
Ma ke ʻano he node optical waho, ua hoʻolālā ʻo GWR1200 i ka pale 4KV surge ma nā awa RF āpau.
Hiki ke hoʻonohonoho ʻia ka mea hoʻihoʻi ala hoʻi GWR1200 ma ke ʻano burst e hōʻemi i ka walaʻau ala hoʻi. Hoʻohana ka hāmeʻa i kahi fiber hoʻokahi a loaʻa nā hōʻailona o lalo ma 1550nm a hiki ke kauoha ʻia nā mea hoʻihoʻi e like me 1310nm a i ʻole 1610nm a i ʻole CWDM wavelengthes ma muli o nā koi ʻōnaehana. Ma ke ʻano he mea RFOG ua kūpono ia me DOCSIS® a me nā hana hoʻoilina a pau o ka HFC back office.
Nā hiʻohiʻona ʻē aʻe:
• Aluminum Die Cast Outdoor Hale.
• Elua mau pulupulu a i ole Single fiber bi-directional optical transmission.
• 1005MHz a i ʻole 1218MHz ala i mua RF bandwidth.
• Hoʻokahi 110dBµV a i ʻole 106 dBµV ʻelua mau hoʻopuka RF i mua.
• Ala i mua 15dB Slop a me 15dB attenuator.
• AGC pono ma -5dBm~+1dBm hoʻokomo optical.
• 5 ~ 85MHz / 204MHz hoʻihoʻi RF bandwidth koho.
• A hiki i ka 16 CWDM DFB laser wavelength e hana ana ma ke ano pahū.
• 4KV Surge Protection.
• 60V aiʻole 220V mana lako.
