I-Super Lowest Satellite Multiswitch (171740S) ene-LED kanye ne-Gain Adjustable

Ukuphishekela kwethu kanye nenhloso yebhizinisi kuzoba “ukufeza izidingo zomthengi njalo”. Siyaqhubeka nokuthola nokuhlela izinto ezisezingeni eliphezulu kumakhasimende ethu amabili amadala namasha futhi sithola ithuba lokuwina-wini kubathengi bethu ngaphezu kwethu kwe-Super Lowest Price Satellite Multiswitch (171740S) ene-LED kanye neGain Adjustable, Samukela ngokufudumele. ukusetha ukubambisana futhi ukhiqize isikhathi eside esiqhakazile kanye nathi.

Incazelo Yomkhiqizo

I-TV yesathelayithi ye-GLB3500E-2R i-FTTH Optical LNB isamukeli se-fiber optic esiguqula isignali yokubona ibe yi-RF kuze kufike kumasathelayithi angu-4 amukela izamukeli ekhaya elilodwa. Isebenza ne-Greatway GLB3500E-2T ye-satellite TV optical transmitter, i-GLB3500E-2R inemojula ye-SatCR eyakhelwe ngaphakathi esebenza ne-wideband satellite RF, ikhipha amabhendi abasebenzisi besathelayithi angu-4 embotsheni eyodwa ye-SatCR RF yabamukeli abangu-4 abangatholakali besathelayithi.

I-LNB evamile i-Low Noise Block, iguqulela i-Ku Band 10.7GHz~12.75GHz RF noma i-C Band engu-3.7GHz~4.2GHz RF iye ku-950MHz~2150MHz IF kumamukeli ahlala. Ku-SMATV ngohlelo lwefayibha, isidluliseli esisodwa siguqula i-LNB IF ibe ifayibha. Ngemuva kwe-fiber optic amplifier ne-PON, isignali ye-optic isatshalaliswa kumakhulu noma izinkulungwane zemindeni ye-FTTH. Ekhaya ngalinye elinekhebula le-fiber, isamukeli esisodwa esibonakalayo siguqula i-fiber ibe yi-Sat IF. Okokufaka kwe-Fiber kuphendukela ku-950MHz ~ 2150MHz IF okukhiphayo IF kumamukeli ahlala.

Isamukeli samehlo esisathelayithi sidlala indima efanayo ne-LNB evamile, iyi-LNB “ebonakalayo” ekhaya. Isamukeli esibonakalayo sesathelayithi singabizwa ngokuthi i-Optical LNB noma i-Fiber LNB.

I-LNB evamile ifakwa esitsheni esibheke esibhakabhakeni. I-Optical LNB ifakwa noma yikuphi ekhaya lapho i-fiber itholakala khona. Okuqukethwe kwe-LNB eyodwa evamile kungaphinda kukhiqizwe kufikela ku-500K optical LNBs.

I-LNB evamile ine-polarities eqondile noma evundlile (13V/18V) kanye nebhendi ephakeme noma ibhendi ephansi (0Hz noma 22KHz). Ngobuchwepheshe be-CWDM/DWDM, i-Optical LNB ingaba nomsebenzi ofanayo nembobo ye-RF esekela i-DiSEqC.

I-GLB3500E-2R ine-1310nm/1490nm/1550nm WDM imbobo yenketho yokusebenzisana ne-GPON ONU kunoma yiluphi uhlelo lwe-FTTH, oluvumela okuqukethwe kwesathelayithi yendabuko ye-Quattro LNB kufakwe ohlelweni lwe-GPON.

Ezinye izici:

•I-High Linearity Photodiode.

•Okokufaka kwefayibha ye-SC/APC.

•Ibanga le-Optical AGC: -6dBm ~ +1dBm.

•Imbobo eyodwa ye-SatCR RF yezamukeli ezihlala ezingatholakali ezi-4 ezihlala ekhaya elilodwa.

•Ukuvinjelwa kwe-RF Sat: 950~2150MHz.

•I-CE igunyaziwe.Inhloso yethu kanye nebhizinisi kuzoba “ukufeza izidingo zomthengi njalo”. Siyaqhubeka nokuthola nokuhlela izinto ezisezingeni eliphezulu kumakhasimende ethu amabili amadala namasha futhi sithola ithuba lokuwina-wini kubathengi bethu ngaphezu kwethu kwe-Super Lowest Price Satellite Multiswitch (171740S) ene-LED kanye neGain Adjustable, Samukela ngokufudumele. ukusetha ukubambisana futhi ukhiqize isikhathi eside esiqhakazile kanye nathi.
Inani Eliphansi KakhuluI-China Multiswitch 171740s kanye ne-Cascade Multiswitch, Ngokulandela isimiso “sokuthambekela komuntu, ukuwina ngekhwalithi”, inkampani yethu yamukela ngobuqotho abathengisi abavela ekhaya nabaphesheya ukuthi basivakashele, bakhulume nathi ngebhizinisi futhi bakhe ngokuhlanganyela ikusasa eliqhakazile.
