Siqhubeleka sifumana kunye nokucwangcisa izinto ezikumgangatho obalaseleyo kubathengi bethu babini abadala kunye nabatsha kwaye sifumana ithemba lokuphumelela kubathengi bethu ukongeza njengathiI-China Multiswitch 171740s kunye neCascade Multiswitch, Ngokuthobela umgaqo "wokuqhelana noluntu, ukuphumelela ngokomgangatho", inkampani yethu yamkele ngokunyanisekileyo abathengisi abavela ekhaya nakwamanye amazwe ukuba basityelele, bathethe ishishini nathi kunye nokudala ngokudibeneyo ikamva eliqaqambileyo.

Ingcaciso yeMveliso

I-TV yesathelayithi ye-GLB3500E-2R FTTH i-Optical LNB yifiber optic receiver eguqula umqondiso obonayo ube yiRF ukuya kuthi ga kwi-4 yesathelayithi yabamkeli kwikhaya elinye. Ukusebenza kunye ne-Greatway GLB3500E-2T ye-satellite TV optical transmitter, i-GLB3500E-2R inemodyuli ye-SatCR eyakhelwe ngaphakathi ejongene ne-wideband satellite RF, ikhupha iibhendi ezi-4 zomsebenzisi wesathelayithi kwizibuko elinye le-SatCR RF kwi-4 unicable satellite receivers.

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 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 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 elixhasa iDiSEqC.

I-GLB3500E-2R ine-1310nm/1490nm/1550nm izibuko le-WDM lokukhetha ukusebenzisana ne-GPON ONU kuso nasiphi na isicelo se-FTTH, esenza ukuba imixholo yesathelayithi ye-Quattro LNB ifakwe kwinkqubo ye-GPON.

Ezinye iimpawu:

•High Linearity Photodiode.

•Igalelo lefiber ye-SC/APC.

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

•Izibuko elinye le-SatCR RF ukuya kuthi ga kwi-4 uniable sat abamkeli kwikhaya elinye.

•Sat RF Ban: 950 ~ 2150MHz.

•I-CE ivunyiwe.Usukelo lwethu kunye nenjongo yeshishini iya kuba "Soloko sizalisekisa iimfuno zethu zomthengi". Siqhubela phambili sifumana kunye nokucwangcisa izinto ezikumgangatho obalaseleyo kubathengi bethu babini abadala kunye nabatsha kwaye sifumana ithemba lokuphumelela kubathengi bethu ukongeza njengathi ngexabiso eliphantsi kakhulu leSatellite Multiswitch (171740S) ene-LED kunye neGain Adjustable, Samkela ngezandla ezishushu. ukuba usete intsebenziswano kwaye uvelise ixesha elide eliqaqambileyo kunye nathi.
Ixabiso eliphantsi kakhuluI-China Multiswitch 171740s kunye neCascade Multiswitch, Ngokuthobela umgaqo "wokuqhelana noluntu, ukuphumelela ngokomgangatho", inkampani yethu yamkele ngokunyanisekileyo abathengisi abavela ekhaya nakwamanye amazwe ukuba basityelele, bathethe ishishini nathi kunye nokudala ngokudibeneyo ikamva eliqaqambileyo.
