GWR1000M CATV MiniNode

GWR1000M Optical MiniNode waxay leedahay hal deked oo RF ah oo leh dariiqa hore ee analooga TV, DVB-C iyo CMTS DS calaamadaha iyo calaamada fiilada kor u kaca ee modemka joogtada ah ama qaabka dilaaca ee ka sarreeya hal fiber-jiho ah ama laba fiilood. Guryaha aluminiumka ah ee gudaha ku jira, GWR1000M waxay ku habboon tahay fiber-ka horumarsan ee dhismaha (FTTP), fiber ilaa dabaqa (FTTF) ama fiber-ka dhismaha (FTTB) codsiyada CATV iyo shabakadaha internetka. GWR1000M node wuxuu bixiyaa hal wax soo saar RF ilaa 1.2 GHz (1218MHz) kaas oo si toos ah u taageera dhowr terminal TV ama ku wadida cod-weyneeye MDU shabakada fiilada coaxial.

GWR1000M node waxay ku fiican tahay codsiyada cufnaanta sare: MDU, jaamacadaha, isbitaalada iyo jardiinooyinka ganacsiga. Iyada oo leh wax soo saarka 20dBmV RF ee qaabka AGC, GWR1000M mininode waxay u qabataa aasaaska cabbir yar si ku habboon. Gudbiyaha dariiqa soo celinta wuxuu noqon karaa 1310nm ama 1550nm 2^nddekedda fiber, taas oo ku xidhan shuruudaha nidaamka. Tiknoolajiyada WDM ee ikhtiyaarka ah waxay u oggolaanaysaa hawlgallada laba-geesoodka ah ee hal fiber ah. CWDM dariiqa soo celinta mawjadaha indhaha ayaa diyaar u ah inay isku daraan noodhka laba-geesoodka ah ee hal fiber ah.

Sida noodhka indhaha gudaha, GWR1000M waxaa lagu dhejin karaa darbiga iyada oo la adeegsanayo boolal ama miiska. Waxay naqshadaysay 6KV ilaalinta qallafsan ee dhammaan dekedaha RF.

GWR1000M waxay leedahay hal deked tijaabo ah -20dB, si fudud ula socoshada dariiqa hore u shaqaynta iyo dariiqa soo noqoshada calaamada RF.

GWR1000M waxaa lagu shubi karaa dekada RF ee madaxa banaan oo leh adabtarada korantada ee 15V DC, taas oo u ogolaanaysa hoos u dhaca korantada DC wax ka yar 30 mitir dhererka fiilada RG6. GWR1000M waxa kale oo lagu shubi karaa dekedda wax soo saarka RF.
