GWR1000M CATV MiniNode

Loaʻa iā GWR1000M Optical MiniNode hoʻokahi awa RF me ka TV analog ala hele mua, nā hōʻailona DVB-C a me CMTS DS a me 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 ʻelua mau fiber. Me nā hale make-cast alumini i loko, kūpono ʻo GWR1000M no ka fiber kiʻekiʻe i ka hale (FTTP), fiber i ka papahele (FTTF) a i ʻole fiber i ka hale (FTTB) nā noi ma CATV a me nā pūnaewele pūnaewele. Hāʻawi ʻo GWR1000M node i hoʻokahi huahana RF a hiki i 1.2 GHz (1218MHz) e kākoʻo pololei ana i nā pahu TV liʻiliʻi a i ʻole hoʻokele MDU amplifier i loko o ka pūnaewele uwea coaxial.

He kūpono ka node GWR1000M no nā noi haʻahaʻa kiʻekiʻe: MDU, nā kulanui, nā halemai a me nā paka ʻoihana. Me ka 20dBmV RF puka ma ke ʻano AGC, ʻo GWR1000M mininode e lawelawe maʻalahi i ka hale liʻiliʻi. Hiki i ka transmitter ala hoʻi ke 1310nm a i ʻole 1550nm ma ka 2^ndfiber port, ma muli o nā koi ʻōnaehana. Hiki i ka ʻenehana WDM koho ke hana i nā hana ʻelua ma ka fiber hoʻokahi. Loaʻa nā lōʻihi hawewe optical CWDM no ka hoʻohui ʻana i nā node ʻelua ʻaoʻao ma ka fiber hoʻokahi.

Ma ke ʻano he node optical i loko, hiki ke kau ʻia ʻo GWR1000M ma ka paia e nā ʻili a i ʻole ma ka papaʻaina. Ua hoʻolālā ʻo ia i ka pale ʻana o 6KV ma nā awa RF āpau.

Loaʻa iā GWR1000M hoʻokahi awa hoʻāʻo -20dB, nānā maʻalahi i ke ala hana i mua a me ke ala hoʻi i ka hōʻailona RF.

Hiki ke hoʻohana ʻia ʻo GWR1000M ma ke awa kūʻokoʻa RF me kahi mea hoʻopili mana 15V DC mamao, kahi e hiki ai i ka hāʻule o ka uila DC ma lalo o 30 mika RG6 lōʻihi. Hiki ke hoʻohana ʻia ʻo GWR1000M ma ke awa puka RF.
