Catv Kho Qhov Muag Tau Muag
SR814 TESM Sab Nraum Zoov Tsav Kho Kho ©
Khoom Txheej Txheem
SR814DMSab nraum zoov Catv Optical tau txais peb lub siab tshiab {}}}}}}}}}}}}}} kho lub network kho qhov muag. Lub pre - Amplifier tau txais txhua - mmic, post-amplifier adopts gaas module. Kev tsim kho hluav taws xob tsim kho kom sib koom ua ke nrog peb 10 xyoo tsim kev paub, cov cuab yeej ua tiav Performance index. Cov kev hloov kho ntawm RF ignenuation thiab kev txawj ntse ob leeg adopts feluenator inserter uas ua rau muaj kev sib cav sib haum xeeb yooj yim. Nws yog cov khoom tseem ceeb los tsim CatV network.
Cov yam ntxwv ua tau zoo
Cov lus teb siab tus Pin photoelectric hloov siab lub raj.
10 bar LED LED cov lus qhia hluav taws xob, ntau dua qhov tseeb ntawm lub zog kho qhov muag.

Cov kev hloov kho ntawm RF Attenishuation thiab kev txawj ntse ob qho tib si tau txais kev nkag siab, EQ txoj hauj lwm tso tawm hauv Insilibrium tuaj yeem hloov pauv qhov sib npaug, yog li cov tshuab nqus ntxeem tau yooj yim heev.
Muab ob npaug rau hluav taws xob tawm, muaj kev loj thiab qis distortion.
Kev tswj hwm tus ntsuas kho qhov muag, thaum cov tswv yim kho qhov muag yog -7 ~+2 dbm, qib tawm, cSOs tsis hloov.
