GLB3500M-3 Terr TV hamwe numuyoboro mugari LNB hejuru ya fibre
Ibisobanuro ku bicuruzwa
GLB3500M-3 numuyoboro mugari wa CWDM mugari wa fibre ya fibre, yohereza bibiri bya 290MHz ~ 2350MHz Satellite RF (ishyigikira UK 290MHz ~ 2340MHz cyangwa Uburayi 300MHz ~ 2350MHz) hamwe na 45MHz ~ 806MHz TV TV yo ku isi kuri fibre imwe ya SM kubakoresha benshi.Umuyoboro mugari wa RF uri kuri 1530nm cyangwa 1550nm, TV yo ku isi RF iri kuri 1570nm.Hano hari fibre optique CWDM mux cyangwa igikoresho cya demux kuri optique ya optique cyangwa kwakira kugirango tumenye fibre imwe.
SMATV (Satellite Master Antenna TV) irazwi cyane gutanga TV ya satelite na TV yo kwisi kubiyandikishije baba mumazu cyangwa mugace.Gakondo ya SMATV irashobora gukwirakwiza ibice bya antenne ikoresheje multiswitch kubakira ibyogajuru hejuru ya kabili ya coaxial.Bitewe nigihombo kinini kuri satelite yo hejuru, intera ya kabili ya SMATV iri munsi ya metero 150 nubwo hamwe na amplifier kumurongo.Bitandukanye na sisitemu isanzwe ya Quattro LNB SMATV, umurongo mugari wa LNB SMATV ifite igice cya kabiri cya RF hamwe numubare wa kabili, bikiza ikiguzi cyo kohereza.Nyuma ya fibre yinyubako, umurongo mugari wa SMATV optique yakira igomba gukorana na dCSS multiswitch kugirango igire umusaruro umwe wa RF hamwe na 32 ukoresha imbaraga, aho buri mukoresha kuri oned unicable satelite abafatabuguzi ba STB.Iyi fibre imwe yinyubako hamwe numuyoboro wa coaxial kubakoresha benshi mumazu bituma kwishyiriraho insinga no kuyitaho byoroshye.
GLB3500M-3 fibre ihuza fibre ikubiyemo GLB3500M-3T optique yohereza hamwe na GLB3500M-3R optique yakira.Hamwe na laseri ya CWDM / Photodiode hamwe n urusaku ruke RF yunguka igenzura, GLB3500M-3T irashobora gutanga RF nziza cyane kuri 32pcs GLB3500M-3R optique yakira neza.
Ibindi biranga:
• Amazu yuzuye ya aluminium.
• Umuyoboro mugari 3 wigenga RF hejuru ya SM fibre.
• Umuyoboro mugari wa RF: umurongo mugari LNB 290 ~ 2350MHz cyangwa 45 ~ 806MHz.
• Photodiode Yumurongo muremure.
• Urusaku ruke RF Yunguka Igenzura.
