GLB3500E-2R FTTH LNB
Product Description
GLB3500E-2R satellite TV FTTH Optical LNB ndeye fiber optic inogamuchira inoshandura optical siginecha kuita RF kune anosvika mana setiraiti anogashira mumba imwe. Kushanda neGreatway GLB3500E-2T satellite TV optical transmitter, GLB3500E-2R yakavaka-muSatCR module inobata ne wideband satellite RF, inoburitsa 4 setiraiti mushandisi mabhendi pane imwe SatCR RF chiteshi kune 4 unicable satellite vanogamuchira.
Regular LNB iLow Noise Block, inoshandura Ku Band 10.7GHz~12.75GHz RF kana C Band 3.7GHz~4.2GHz RF kusvika 950MHz~2150MHz IF kune sat receiver. 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 zvinogona 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.
GLB3500E-2R ine 1310nm/1490nm/1550nm WDM sarudzo port yekushanda pamwe neGPON ONU mune chero FTTH application, iyo inogonesa zvechinyakare setiraiti Quattro LNB zvirimo zviiswe muGPON system.
Zvimwe Zvimiro:
•High Linearity Photodiode.
•SC/APC faibha kuisa.
