Ingcaciso yeMveliso

I-GLB2000A ye-TV yesathelayithi FTTH i-LNB yamehlo iguqula umqondiso obonayo ube ziipolarities ezimbini zeRF zomamkeli wesathelayithi enye. Ukusebenza nge-Greatway GLB3500A-2T yesathelayithi ye-fiber optic transmitter ye-TV, i-GLB2000A ikhupha umgangatho ophezulu we-Terrestrial TV+ Umqondiso we-RF othe nkqo/othe tye. Le LNB ye-ftth inokutshintsha i-Vertical (okanye i-RHCP) okanye i-Horizontal (okanye i-LHCP) isignali yemveliso nge-13V okanye i-18V DC yamandla asuka kumamkeli wesathelayithi.

I-LNB yesiqhelo yiBhlokhi yeNgxoxo ePhantsi, iguqula i-Ku Band 10.7GHz~12.75GHz RF okanye i-C Band 3.7GHz~4.2GHz RF ukuya ku-950MHz~2150MHz IF kumamkeli ahlala. Kwi-SMATV ngaphezulu kwenkqubo yefayibha, isidluliseli esinye siguqula i-LNB IF kwifayibha. Emva kwe-fiber optic amplifier kunye ne-PON, isignali ye-optic isasazwa kumakhulu okanye amawaka eentsapho ze-FTTH. Kwikhaya ngalinye elinefayibha intambo, enye i-optical receiver iguqula ifayibha ibe yiSat IF. Igalelo leFayibha lijikela kwi-950MHz ~ 2150MHz IF imveliso yesat receiver.

• Isathelayithi yokwamkela i-optical receiver idlala indima efanayo ne-LNB eqhelekileyo, yi-LNB “ebonakalayo” ekhaya. Isathelayithi i-optical receiver inokubizwa ngokuba yi-Optical LNB okanye iFiber LNB.
• I-LNB eqhelekileyo ifakwa kwisitya esijonge esibhakabhakeni. I-Optical LNB ifakwe naphi na ekhaya apho ifayibha ifumaneka khona. Imixholo ye-LNB enye eqhelekileyo inokuveliswa ukuya kuthi ga kwi-500K ye-LNB yamehlo
• I-LNB yesiqhelo ineepolarities ezithe nkqo okanye ezithe tye (13V/18V) kunye nebhendi ephezulu okanye esezantsi (0Hz okanye 22KHz). Ngeteknoloji yeCWDM/DWDM, i-LNB yamehlo inokuba nomsebenzi ofanayo wezibuko le-RF kwifiber enye ye-SM.

I-LNB yesiqhelo yiBhlokhi yeNgxoxo ePhantsi, iguqula i-Ku Band 10.7GHz~12.75GHz RF okanye i-C Band 3.7GHz~4.2GHz RF ukuya ku-950MHz~2150MHz IF kumamkeli ahlala.

I-LNB eqhelekileyo ifakwa kwisitya esijonge esibhakabhakeni. I-Optical LNB ifakwe naphi na ekhaya apho ifayibha ifumaneka khona. Imixholo ye-LNB enye eqhelekileyo inokuphinda iveliswe ukuya kuthi ga kwi-500K yee-LNB zamehlo.

I-LNB yesiqhelo ineepolarities ezithe nkqo okanye ezithe tye (13V/18V) kunye nebhendi ephezulu okanye ibhendi esezantsi (0Hz okanye 22KHz). Ngeteknoloji yeCWDM/DWDM, i-LNB yamehlo inokuba nomsebenzi ofanayo wezibuko le-RF kwifiber enye ye-SM.

I-GLB2000A ine-1310nm/1490nm inketho ye-WDM yokusebenzisana kunye ne-GPON/EPON ONU kuyo nayiphi na imeko ye-FTTH, eyenza ukufaka i-DTT+SAT phezu kwe-GPON/EPON network.

Ezinye iimpawu:

•Indlu yeplastiki ebambeneyo ebuyisela idangatye.

•High Linearity Photodiode.

•Igalelo lefiber ye-SC/APC.

•Uluhlu lwe-AGC olubonakalayo: -6dBm ~ +1dBm.

•Sat RF Bandwidth: 950MHz ~ 2150MHz.

•I-Terestrial TV RF Bandwidth: 174~806MHz.

•I-Terestrial TV + Horizontal (LHCP)@18V DC isuka kumamkeli wesathelayithi..

•I-Terestrial TV + nkqo (RHCP)@13V DC ukusuka kumamkeli wesathelayithi.

•Ichweba le-WDM elikhethiweyo ukuya kwi-GPON ONU.Kunye nefilosofi yeshishini elincinci elithi "I-Client-Oriented", inkqubo yokuphatha esemgangathweni ophezulu, oomatshini bokuvelisa abaphuhliswe kakhulu kunye neqela elinamandla le-R & D, sihlala sibonelela ngeemveliso ezikumgangatho ophezulu kunye nezisombululo, iinkonzo ezimnandi kunye iindleko ezindlongo-ndlongo zeCatvscope yeBor20 yeSatellite Optical Receiver eThengisa kakhulu, Besizingela kwangaphambili intsebenziswano engcono namazwe angaphandle ngokusekwe kwiingenelo ezifanayo.
