GLB3500M-4D Satelite enye DWDM FTTH hamwe na GPON
Ibisobanuro ku bicuruzwa
GLB3500M-4D ni umuyoboro mugari wa DWDM mugari wa fibre ya RF, wohereza Satellite RF enye 950 ~ 2150MHz hamwe na 174 ~ 806MHz TV yo ku isi RF kuri fibre imwe ya SM kubakoresha benshi ba FTTH. Ibyogajuru bine bya RF birashobora kuba VL / VH / HL / HH kuva muri Quattro LNB imwe cyangwa static 32UB kuva kuri satelite enye dCSS LNBs.
Satelite enye zifite transponders nyinshi kuri buri cyogajuru. Mubyukuri, 20% gusa biri muri satelite irazwi mubiyandikishije 80%. Ibintu byose biva kuri satelite enye hejuru ya coaxial kugeza fibre fibre kuri buri rugo bihenze. Sisitemu ya GLB3500M-4D ihitamo transponders izwi cyane kubakoresha bose. 32 transponders kuri buri cyogajuru igomba gushiramo ibintu bigaragara cyane muri satelite. Hamwe na 4ch ya tekinoroji ya DWDM nimbaraga nyinshi 1550nm optique amplifier, GLB3500-4D irashobora kwinjiza satelite 4 hamwe na transponders 128 zose muri sisitemu iyo ari yo yose ya GPON cyangwa XGPON. Kuri dCSS LNB ihagaze neza, imashini ya satelite irashobora kuba uburyo busanzwe bwo kureba ibyogajuru byose uko ari 4 byatoranijwe.
GLB3500M-4D ihuza fibre ikubiyemo GLB3500M-4TD DWDM ya optique yohereza hamwe na GLB3500M-4RD4 FTTH yakira optique. Ibyakirwa neza bifite ibyambu 4 bya RF, buri cyambu gishyigikira kureba 32UB yinjira ya satelite yose yinjira. Hamwe na laseri ya DWDM / Photodiode hamwe n urusaku ruke RF yunguka igenzura, GLB3500M-4TD imwe irashobora gutanga RF yo murwego rwohejuru kuri 32 GLB3500M-4RD4 optique yakira neza cyangwa ibihumbi n'ibihumbi bya GLB3500M-4RD4 optique ikoresheje imbaraga nyinshi za optique.
Ibindi biranga:
• Gucumbikira aluminiyumu hamwe na heatsink nziza hamwe na RF kwigunga.
• Quattro imwe LNB (cyangwa enye dCSS LNBs) na TV ya Terr hejuru ya SM fibre imwe.
• Umuyoboro wa satelite enye RF: 950MHz kugeza 2150MHz.
• Hindura 13V / 18V DC kuri Quattro LNB cyangwa dCSS LNB.
