GLB3500A-2R Twin Fiber Optic LNB

GLB3500A-2R setiraiti LHCP/RHCP FTTH Optical LNB isfiber optic inogamuchira inoshandura optical sign kuita RF kweanopfuura maviri anogamuchira setiraiti. Kushanda neGreatway GLB3500A-2T satellite TV fiber optic transmitter, GLB3500A-2R inoburitsa zvemhando yepamusoro Terrestrial TV+ LHCP uye Terrestrial TV + RHCP RF chiratidzo kumhuri imwe ine vanopfuura vaviri vanogamuchira setiraiti. Iyi FTTH Twin LNB inogona kuva nemagetsi maviri eRF, imwe neimwe RF port inogona kushandura LHCP kana RHCP inobuda chiratidzo ne13V kana 18V DC simba kubva kune satellite inogamuchira.

RegularLNBndizvoLowNoiseBkukiya, kushandura Ku Band 10.7GHz~12.75GHz RF kana C Band 3.7GHz~4.2GHz RF kuenda ku950MHz~2150MHz IF yemugamuchiri akagara. PaSMATV pamusoro pefiber system, imwe transmitter inoshandura LNB IF kuita fiber. Mushure me fiber optic amplifier nePON, chiratidzo chemaziso chinogoverwa kumazana kana zviuru zvemhuri dzeFTTH. Pamba yega yega ine fiber tambo, imwe yekuona inogamuchira inoshandura fiber kuita Sat IF. Fiber yekupinda inotendeukira ku950MHz ~ 2150MHz IF inobuda kune yakagara inogamuchira.

Satellite Optical receiver inoita basa rakafanana nerenguva dzose LNB, iri "virtual" LNB kumba. Satellite Optical receiver inogona kunzi Optical LNB kana Fiber LNB.

Regular LNB inoiswa mundiro yakatarisa mudenga. Optical LNB inoiswa chero kumba uko kune fiber inowanikwa. Zviri mukati meimwe yenguva dzose LNB inogona kugadzirwazve kusvika ku500K optical LNBs.

Yenguva dzose LNB ine polarities yakatwasuka kana yakatwasuka (13V/18V) uye bhendi repamusoro kana bhendi rezasi (0Hz kana 22KHz). Nekuburikidza neCWDM/DWDM tekinoroji, yekuona LNB inogona kuita basa rakafanana reRF port inotsigira DiSEqC.

GLB3500A-2R ine 1310nm/1490nm WDM sarudzo yekushanda pamwe chete neGPON/EPON ONU mune chero FTTH kesi, inogonesa kuisa satellite TV pamusoro peGPON/EPON network.
