IMINININGWANE YOMKHIQIZO

Incazelo Yomkhiqizo

I-GFH2000-K ingu-45~2600MHz 1550nm isamukeli se-fiber optic esinembobo ye-WDM eya ku-FTTH ONU.Njengesisekelo se-fiber optic LNB, i-GFH2000-K ine-wideband LNB (300MHz ~2350MHz) noma i-LNB evamile (950MHz~2150MHz)+CATV RF amabhendi, isebenza ne-GWT3500S (CATV+Sat) i-fiber optic transmitter noma i-GLB3500MTr TV-D (Terr+D) Sat IF) i-fiber optic transmitter noma i-wideband optical transmitter.

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 sokubonwa kwesathelayithi 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.

Njenge-LNB yokubona yonke indawo, i-GFH2000-K ingasebenza nanoma iyiphi inkampani yangaphandle i-GPON ONU noma i-1270nm/1577nm XGPON ONU noma 1524~1544/1596~1599nm NGPON2 ONU, ifake ukusakazwa okukhulu kwekhwalithi ephezulu ye-CAFTTH+ SAT amavidiyo ngaphandle kokuhlanganisa amavidiyo e-inthanethi umkhawulokudonsa.
