I-Catvscope ye-Bor20 ye-Satellite Optical Receiver ethengiswa Kakhulu

Kanye nefilosofi yamabhizinisi amancane “Agxile Kubathengi”, uhlelo oluqinile lokubamba lwekhwalithi ephezulu, imishini yokukhiqiza ethuthuke kakhulu kanye neqembu elinamandla le-R&D, sihlala sihlinzeka ngemikhiqizo nezisombululo zekhwalithi ephezulu, izinsizakalo ezinhle nezindleko ezinolaka ze-Catvscope Ethengiswa Kakhulu. I-Bor20 Satellite Optical Receiver, Besizingela kusengaphambili ukubambisana okungcono nakakhulu namathemba aphesheya asekelwe kuzinzuzo ezifanayo. Qiniseka ukuthi uzizwa ukhululekile ngempela ukukhuluma nathi ukuze uthole ukujula okwengeziwe!

Njengokubuyekezwa komkhiqizo ngokushesha, siphumelela ukuthuthukisa izinto eziningi zekhwalithi ephezulu kumakhasimende ethu futhi sithole isithunzi esiphezulu.

Incazelo Yomkhiqizo

I-GLB2000A TV yesathelayithi ye-FTTH i-LNB yokubona iguqula isignali yokubona ibe izingxenye ezimbili ze-RF kwesamukeli esisodwa sesathelayithi. Isebenza ne-Greatway GLB3500A-2T ye-TV yesathelayithi ehambisa i-fiber optic transmitter, i-GLB2000A ikhipha isignali yekhwalithi ephezulu ye-Terrestrial TV+ Vertical/Horizontal RF. Le LNB ye-ftth ingashintsha isignali ephumayo Eqondile (noma i-RHCP) noma Evundlile (noma i-LHCP) ngamandla angu-13V noma angu-18V DC asuka kwesamukeli sesathelayithi.

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.

• Isathelayithi yokubona eyamukelayo idlala 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 kuze kufike 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 wembobo ye-RF kusuka ku-SM fiber eyodwa.

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-GLB2000A inenketho engu-1310nm/1490nm WDM yokusebenzisana ne-GPON/EPON ONU kunoma yisiphi isimo se-FTTH, esivumela ukufaka i-DTT+SAT phezu kwenethiwekhi ye-GPON/EPON.

Ezinye izici:

•Izindlu zepulasitiki eziqinile ezibuyisela amalangabi.

•I-High Linearity Photodiode.

•Okokufaka kwefayibha ye-SC/APC.

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

•Umkhawulokudonsa we-RF Sat: 950MHz~2150MHz.

•I-Terrestrial TV RF Ububanzi: 174~806MHz.

•I-Terrestrial TV + Horizontal (LHCP)@18V DC kusukela kumamukeli wesathelayithi..

•I-Terrestrial TV + Imile (RHCP)@13V DC evela kumamukeli wesathelayithi.

•Imbobo yokuzikhethela ye-WDM eya e-GPON ONU.
