GLB3500MT Terr TV thiab Sat Fiber Optic Transmitter
Product Description
GLB3500M yog ib qho modular 45 ~ 2600MHz RF tshaj fiber ntau txuas, xa cov Terrestrial TV raws thiab ib leeg L-Band RF tshaj ib fiber.
Direct Broadcasting Satellite (DBS) thiab Direct to Home (DTH) yog txoj kev nyiam tshaj plaws rau kev txaus siab rau satellite TV thoob ntiaj teb. Txhawm rau ua nws, satellite kav hlau txais xov, coaxial cable, splitter lossis multi-switcher thiab satellite receiver yog tsim nyog. Txawm li cas los xij, kev teeb tsa satellite kav hlau txais xov yuav nyuaj rau cov neeg siv khoom nyob hauv cov tsev. SMATV (satellite mater kav hlau txais xov TV) yog ib qho kev daws teeb meem zoo rau cov neeg nyob hauv lub tsev lossis cov zej zog sib koom ib lub phaj satellite thiab cov kav hlau txais xov hauv av. Nrog fiber ntau cable, SMATV RF teeb liab tuaj yeem xa mus rau 30Km nyob deb lossis faib rau 32 chav ncaj qha, mus rau 320 lossis 3200 lossis 32000 chav tsev ntawm GWA3530 fiber optic amplifier.
GLB3500M muaj GLB3500MT transmitter module thiab GLB3500MR receiver module. GLB3500MT transmitter module muaj ib lossis ob lub RF input ports thaum GLB3500MR muaj ib qhov chaw nres nkoj RF. Nrog high linearity 1550nm uncooled DFB laser, photodiode thiab tsis tshua muaj suab nrov RF nce tswj Circuit Court, GLB3500MT tuaj yeem xa cov khoom zoo hauv Terrestrial TV thiab satellite RF tshaj fiber ntau rau ob peb tus neeg siv ncaj qha lossis ntau txhiab tus FTTH cov neeg siv ntawm EDFA. Nrog 1310nm / 1490nm / 1550nm WDM kev xaiv, GLB3500M tuaj yeem ntxig L-Band + TV RF hla GPON / GEPON. Ib sab ntawm modular version, GLB3500M tuaj yeem muaj 19 "1RU version raws li kev thov. Cov fiber ntau rau lub tsev yas vaj tsev version ntawm GLB3500MR yog GFH2000 kho qhov muag LNB, qhov twg FTTH cov neeg siv khoom tsuas yog xav tau ib qho fiber ntau hauv thiab tso tawm satellite teeb liab rau ntau chav hauv tsev neeg.
Lwm yam nta:
• Compact aluminium tuag cast vaj tsev.
• Ib leeg ua ke RF input nrog bandwidth: 45 ~ 2600MHz los yog.
• Ob qhov sib cais RF inputs, suav nrog:
-Ib qho kev tawm tswv yim hauv Terrestrial TV, bandwidth: 174 -806 MHz.
-Ib LNB RF input, bandwidth: 950MHz ~ 2150MHz (13V lossis 18V DC xaiv rau LNB ntawm kev thov).
• Ib qho RF tso zis chaw nres nkoj.
• High Linearity 1550nm uncooled DFB Laser thiab Photodiode.
• Tsis tshua muaj suab nrov RF Gain Control Circuit Court.
