Dabagalkeena iyo hadafkayaga ganacsi waxay noqon doontaa "had iyo jeer buuxin shuruudaha iibsadaha". Waxaan sii wadnaa si aan u helno oo aan u habeyno alaab tayo sare leh oo loogu talagalay labada macaamiisheena hore iyo kuwa cusub waxaanan xaqiijineynaa rajada guul-guuleysiga ee dukaameystayaasheena marka lagu daro anaga qiimaha ugu hooseeya Satellite Multiswitch (171740S) oo leh LED iyo helitaanka La hagaajin karo, Waxaan si diiran u soo dhaweyneynaa in aad sameysataan iskaashi oo aad nala abuurtaan waqti dheer oo dhalaalaya.
Dabagalkeena iyo hadafkayaga ganacsi waxay noqon doontaa "had iyo jeer buuxin shuruudaha iibsadaha". Waxaan sii wadnaa inaan u soo saarno oo aan u qaabeyno alaab tayo wanaagsan leh labada macaamiisheena hore iyo kuwa cusub waxaanan xaqiijineynaa rajo guul-guul ah dukaameystayaasheena marka lagu daro annagaShiinaha Multiswitch 171740s iyo Cascade Multiswitch, Adigoo raacaya mabda'a "ujeedada aadanaha, ku guuleysiga tayada", shirkadeena waxay si daacad ah u soo dhaweyneysaa ganacsatada gudaha iyo dibaddaba inay nagu soo booqdaan, ganacsi nala hadlaan oo si wadajir ah u abuuraan mustaqbal ifaya.

Sharaxaada Alaabta

GLB3500E-2R satellite TV FTTH Optical LNB waa aqbalaha fiber optic-ga oo u beddelaya signalka indhaha RF ilaa 4 satalayt qaatayaasha hal guri. La shaqaynta Greatway GLB3500E-2T satellite TV-ga gudbiyaha indhaha, GLB3500E-2R waxa ay ku dhex dhisantay moduleka SatCR oo la tacaalaya dayax gacmeedka RF, waxa uu soo saara 4 satalaytka isticmaala hal deked SatCR RF oo loogu talagalay 4 qaata satalaytka oo aan awood u lahayn.

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.

Satelite-ka qaataha indhaha waxa uu ciyaaraa door la mid ah kan caadiga ah ee LNB, waa LNB-ga guriga dhexdiisa “virtual”. 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 oo caadi ah ayaa dib loo soo saari karaa ilaa 500K indhaha LNBs.

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 ee taageerta DiSEqC.

GLB3500E-2R waxay haysataa 1310nm/1490nm/1550nm WDM doorasho deked ah oo wada shaqayn la leh GPON ONU codsi kasta oo FTTH ah, kaas oo awood u siinaya waxyaabaha ku jira dayax gacmeedka Quattro LNB in ​​la geliyo nidaamka GPON.

Sifooyin kale:

•Linearity Photodiode.

•SC/APC galinta fiber-ka

•Kala duwanaanshaha AGC indhaha: -6dBm ~ +1dBm.

•Hal deked oo SatCR RF ah oo loogu talagalay ilaa 4 qof oo fadhi ku dirir ah oo aan awoodin oo ku yaal hal guri.

•Xayiraadda Sat RF: 950 ~ 2150MHz.

•CE waa la oggolaaday. Ujeeddadayada iyo ujeeddadayada ganacsigu waxay noqonaysaa "had iyo jeer buuxinta shuruudaha iibsadaha". Waxaan sii wadnaa si aan u helno oo aan u habeyno alaab tayo sare leh oo loogu talagalay labada macaamiisheena hore iyo kuwa cusub waxaanan xaqiijineynaa rajada guul-guuleysiga ee dukaameystayaasheena marka lagu daro anaga qiimaha ugu hooseeya Satellite Multiswitch (171740S) oo leh LED iyo helitaanka La hagaajin karo, Waxaan si diiran u soo dhaweyneynaa in aad sameysataan iskaashi oo aad nala abuurtaan waqti dheer oo dhalaalaya.
Qiimaha ugu hooseeyaShiinaha Multiswitch 171740s iyo Cascade Multiswitch, Adigoo raacaya mabda'a "ujeedada aadanaha, ku guuleysiga tayada", shirkadeena waxay si daacad ah u soo dhaweyneysaa ganacsatada gudaha iyo dibaddaba inay nagu soo booqdaan, ganacsi nala hadlaan oo si wadajir ah u abuuraan mustaqbal ifaya.
