Gịnị kpatara Fiber Optic Repeater?
Ezubere usoro Kingtone Fiber Optic Repeaters iji dozie nsogbu nke akara ekwentị na-adịghị ike, nke dị ọnụ ala karịa ịtọlite ọdụ ọdụ ọhụrụ (BTS).Isi ọrụ nke sistemu RF Repeaters: Maka njikọ ala, akara sitere na BTS na-enye nri na Master Unit (MU), MU wee gbanwee akara ngosi RF ka ọ bụrụ akara laser wee nye nri na eriri iji bufee na Remote Unit (RU).RU wee gbanwee akara laser ka ọ bụrụ akara RF, wee jiri Power Amplifier mee ka ike dị elu na IBS ma ọ bụ antenna mkpuchi.Maka njikọ elu, Bụ usoro ntụgharị, a na-enye akara sitere na ekwentị mkpanaaka na ọdụ ụgbọ mmiri MU nke MS.Site na duplexer, mgbama na-abawanye site na ụda mkpọtụ dị ala iji kwalite ike mgbaama.Mgbe ahụ, a na-enyefe akara ngosi na RF fiber optical module wee gbanwee gaa na akara laser, mgbe ahụ, a na-ebufe akara ngosi laser na MU, akara ngosi laser sitere na RU na-atụgharị gaa na mgbaàmà RF site na transceiver RF.Mgbe ahụ, a na-ebuli akara ngosi RF ka ọ bụrụ akara ike ọzọ enyere na BTS.
Atụmatụ:
- Fiber Optic RF Repeater bụ ngwọta a pụrụ ịdabere na ya iji gbasaa ma melite mpaghara mkpuchi nke netwọk TETRA 400MHz.
- Ihe mejupụtara modulu abụọ bụ isi, Master na ọtụtụ ngalaba ohu.
- 33, 37, 40 ma ọ bụ 43dBm ike mmepụta ike, izute ụkpụrụ sistemụ.
- Ntinye na mmezi ubi dị mfe na-ebelata ibugharị na ụgwọ ọrụ
- Mgbama mgbasa ozi na fiber optic repeater adịghị enye nsogbu site na mmetụta ndị ọzọ
- Nye ọrụ mkpuchi RF ngwa ngwa na ọdụ ọdụ TETRA gị
- Nha kọmpat na arụ ọrụ dị elu na mkpuchi mmiri adịghị mma maka nrụnye n'èzí na ime ụlọ
