GLB3500MT Terr TV na Sat Fibre Optic Transmitter
Ibisobanuro ku bicuruzwa
GLB3500M ni modular 45 ~ 2600MHz RF hejuru ya fibre ihuza, ikwirakwiza imiyoboro ya tereviziyo yo ku isi hamwe na L-Band RF imwe kuri fibre imwe.
Satellite itaziguye (DBS) na Direct to Home (DTH) nuburyo buzwi cyane bwo kwishimira TV ya satelite kwisi yose. Kubikora, antenne ya satelite, umugozi wa coaxial, splitter cyangwa swift nyinshi hamwe niyakira rya satelite birakenewe. Ariko, kwishyiriraho antenne ya satelite birashobora kugora abiyandikisha baba mumazu. SMATV (satelite mater antenna TV) nigisubizo cyiza kubantu baba mu nyubako cyangwa abaturage gusangira ibyokurya bimwe bya satelite na antenne ya TV yo ku isi. Hamwe na fibre fibre, ibimenyetso bya SMATV RF birashobora kugezwa kuri 30Km kure cyangwa bigakwirakwizwa mubyumba 32 bitaziguye, mubyumba 320 cyangwa 3200 cyangwa 32000 binyuze muri GWA3530 fibre optique.
GLB3500M igizwe na GLB3500MT module yoherejwe na module ya GLB3500MR. Moderi ya GLB3500MT ifite icyambu kimwe cyangwa bibiri byinjira muri RF mugihe GLB3500MR ifite icyambu kimwe gisohoka RF. Hamwe n'umurongo muremure wa 1550nm idakonje ya lazeri ya DFB, fotodiode hamwe n urusaku ruke RF yunguka kugenzura, GLB3500MT irashobora gutanga imiyoboro myiza ya tereviziyo yo ku isi hamwe na satelite RF hejuru ya fibre kubakoresha bake cyangwa ibihumbi by'abafatabuguzi ba FTTH binyuze muri EDFA. Hamwe na 1310nm / 1490nm / 1550nm WDM ihitamo, GLB3500M irashobora gushyiramo L-Band + TV RF hejuru ya GPON / GEPON. Usibye verisiyo ya modular, GLB3500M irashobora kugira 19 ”1RU iyo ubisabye. Fibre yo munzu yububiko bwa plastike ya GLB3500MR ni GFH2000 optique LNB, aho umufatabuguzi wa FTTH akenera fibre imwe gusa kandi asohora ibimenyetso bya satelite mubyumba byinshi mumuryango.
Ibindi biranga:
• Gucomeka aluminiyumu apfa amazu.
• Ihuriro rimwe ryinjiza RF hamwe numuyoboro mugari: 45 ~ 2600MHz cyangwa.
• Ibice bibiri bitandukanye bya RF byinjijwe, harimo:
-Icyerekezo kimwe cya tereviziyo yo ku isi, umurongo mugari: 174 -806 MHz.
-Imwe muri LNB RF yinjiza, umurongo mugari: 950MHz ~ 2150MHz (13V cyangwa 18V DC ihitamo kuri LNB ubisabye).
• Icyambu kimwe gisohoka RF.
• Umurongo muremure 1550nm idakonje DFB Laser na Photodiode.
• Urusaku ruke RF Yunguka Igenzura.
