Iibka ugu Wanaagsan ee Catvscope Bor20 Satellite Optical Receiver
Iyada oo ay weheliso falsafada ganacsiga yar yar ee "Client-oriented", nidaam gacan-qabsi oo tayo sare leh, mashiinno wax soo saar sare leh iyo koox awood leh oo R&D ah, waxaan had iyo jeer siinaa alaab tayo sare leh iyo xalal, adeegyo fantastik ah iyo kharashyo gardarro ah oo loogu talagalay iibinta ugu wanaagsan ee Catvscope Bor20 Satellite Optical Receiver, Waxaan horay u ugaarsanaynay si aan xitaa iskaashi wanaagsan ula yeelanno rajada dibadda iyadoo ku saleysan faa'iidooyinka labada dhinac. Hubi inaad runtii xor u tahay inaad nala hadasho si qoto dheer oo dheeraad ah!
Iyada oo ay la socoto falsafada ganacsiga yar yar ee "Client-oriented", nidaam gacan-qabsi oo tayo sare leh, mashiino wax soo saar oo heer sare ah oo horumarsan iyo koox R&D awood leh, waxaan had iyo jeer bixinaa alaab tayo sare leh iyo xalal, adeegyo fantastik ah iyo kharash gardarro ahChina Optical Receiver iyo Satellite, Waxaan siin karnaa macaamiisheena faa'iidooyinka buuxda ee tayada alaabta iyo xakamaynta qiimaha, waxaanan hadda haysannaa noocyo kala duwan oo ka mid ah ilaa boqol warshadood. Sida ugu dhakhsaha badan ee alaabta loo cusbooneysiiyo, waxaan ku guuleysaneynaa inaan u horumarino macaamiisheenna waxyaabo badan oo tayo sare leh oo aan helno sumcad sare.
Sharaxaada Alaabta
GLB2000A satellite TV FTTH indhaha LNB waxay u beddeshaa signalka indhaha laba polarities RF hal satalayt qaataha. La shaqaynta Greatway GLB3500A-2T satellite TV fibre optic gudbiyaha, GLB2000A waxay soo saartaa tayada sare ee Terrestrial TV+ Toosan/Horizontal RF signal. LNB-dan shanaad waxa ay beddeshaa calaamadda soo saarista toosan (ama RHCP) ama Horizontal (ama LHCP) ee 13V ama 18V DC ee ka imanaya satalaytka.
LNB-ga joogtada ahi waa Block sanqadh hooseeya, oo u beddelaya Ku Band 10.7GHz~12.75GHz RF ama C Band 3.7GHz~4.2GHz RF ilaa 950MHz~2150MHz HADDII loogu talagalay qaataha fadhiga. Marka SMTV ka sarreeya nidaamka fiber-ka, hal gudbiye ayaa u beddela LNB HADDII fiber. Kadib fibre optic amplifier iyo PON, signalka indhaha waxa loo qaybiyaa boqollaal ama kumanaan qoys oo FTTH ah. Guri kasta oo leh fiilada fiber-ka, mid ka mid ah qaataha indhaha ayaa fiber u beddela Sat IF. Gelitaanka fiber-ku wuxuu noqdaa 950MHz ~ 2150MHz HADDII wax soo saarka sat qaataha.
• Satellite optical receiver waxa uu ciyaaraa door la mid ah kan caadiga ah ee LNB, waa "virtual" LNB guriga. Satelite-ka qaataha indhaha waxa loogu yeeri karaa Optical LNB ama Fiber LNB.
• LNB joogto ah ayaa lagu rakibay saxanka cirka u jeeda. Optical LNB waxa lagu rakibay meel kasta oo guriga ka mid ah oo fiber laga heli karo. Waxa ku jira hal LNB caadi ah ayaa dib loo soo saari karaa ilaa 500k LNB-yada indhaha
• LNB-ga joogtada ahi waxa uu leeyahay tiirar toosan ama toosan (13V/18V) iyo band sare ama qayb hoose (0Hz ama 22KHz). Iyada oo la adeegsanayo tignoolajiyada CWDM/DWDM, indhaha LNB waxay yeelan karaan shaqo isku mid ah dekedda RF hal fiber SM ah.

LNB-da caadiga ah waxay leedahay tiirar toosan ama toosan (13V/18V) iyo band sare ama qayb hoose (0Hz ama 22KHz). Iyada oo la adeegsanayo tignoolajiyada CWDM/DWDM, indhaha LNB waxay yeelan karaan shaqo isku mid ah dekedda RF hal fiber SM ah.
GLB2000A waxay haysataa 1310nm/1490nm WDM ikhtiyaar ah oo loogu talagalay la shaqaynta GPON/EPON ONU kiis kasta oo FTTH ah, kaas oo awood u siinaya gelinta DTT+SAT shabakada GPON/EPON.
Sifooyin kale:
•Guryaha dib u dhiga ololka balaastiga ah.
•Linearity Photodiode.
•SC/APC galinta fiber-ka
•Kala duwanaanshaha AGC indhaha: -6dBm ~ +1dBm.
•Sat RF Bandwidth: 950MHz ~ 2150MHz.
•Dhexdhexaadiyaha TV-ga dhulka ee RF: 174~806MHz.
•TV-ga dhulka + Horizontal (LHCP)@18V DC
•TV-ga dhulka
•Dekedda WDM Ikhtiyaarka ah ee GPON ONU.Iyadoo ay la socoto falsafada ganacsiga yar-yar ee "Client-oriented", nidaam adag oo tayo sare leh, mashiinnada wax soo saarka aadka u horumarsan iyo koox R&D awood leh, waxaan had iyo jeer bixinaa alaab tayo sare leh iyo xalal, adeegyo fantastik ah iyo Kharashka gardarrada ah ee iibka ugu fiican ee Catvscope Bor20 Satellite Optical Receiver, Waxaan horay ugaarsanaynay xitaa iskaashi wanaagsan oo lala yeesho rajada dibadda oo ku saleysan faa'iidooyinka labada dhinac. Hubi inaad runtii xor u tahay inaad nala hadasho si qoto dheer oo dheeraad ah!
Iibinta ugu WanaagsanChina Optical Receiver iyo Satellite, Waxaan siin karnaa macaamiisheena faa'iidooyinka buuxda ee tayada alaabta iyo xakamaynta qiimaha, waxaanan hadda haysannaa noocyo kala duwan oo ka mid ah ilaa boqol warshadood. Sida ugu dhakhsaha badan ee alaabta loo cusbooneysiiyo, waxaan ku guuleysaneynaa inaan u horumarino macaamiisheenna waxyaabo badan oo tayo sare leh oo aan helno sumcad sare.
