Kev piav qhia
CATV directional couplers yog sib xws nrog Regal directional couplers. Tus Qauv: 312 DC-xxdB series muaj ntau yam kais poob thiab muab kev ua haujlwm zoo RF. Qhov no CATV Directional Coupler feature 5/8 nti -24 NEF-poj niam ports rau hauv thiab tso tawm cable txuas ntawm lub tsev. Cov couplers tuaj yeem txuas tau los ntawm qhov clamp ntawm lub nraub qaum ntawm lub tsev lossis nto mounted nrog ib qho kev xaiv bracket. Kev sim nyob rau hauv ib puag ncig huab cua, cov khoom sib txuas tau tsim los ua haujlwm ze ntawm cov dej ntsev, nrog rau txoj kev loj thiab kub heev.
Nta
◆ 5-1000MHz puv band ua haujlwm.
◆ Nickel plated tooj dag "F" txuas nrog kev tiv thaiv dej tsis zoo.
◆ Woven metallic gasket siv los muab Hi-RFI.

Puas yog CATV directional couplers passive lossis nquag siv?
CATV directional couplers yog cov khoom siv passive, txhais tau tias lawv tsis xav tau lub zog sab nraud rau kev ua haujlwm. Lawv cia siab rau lub cev lub cev ntawm cov khoom nyob rau hauv lub coupler rau phua los yog ua ke cov teeb liab.
Yuav ua li cas yuav tsum tau nruab CATV directional couplers?
Directional couplers feem ntau ntsia tau rau hauv kab nrog cov kab tseem ceeb, sab hauv tsev lossis sab nraum zoov, nyob ntawm daim ntawv thov. Ua raws li cov chaw tsim khoom cov lus qhia rau kev txhim kho kom raug thiab xyuas kom meej tias kev sib txuas muaj kev ruaj ntseg kom txo cov teeb liab poob thiab cuam tshuam.
CATV cov kev taw qhia txuas txuas puas tuaj yeem siv rau satellite TV systems?
Yog lawm, cov kev taw qhia txuas tuaj yeem siv rau hauv satellite TV faib tshuab los faib lossis sib txuas cov teeb liab. Txawm li cas los xij, nws yog ib qho tseem ceeb los xyuas kom meej tias qhov sib txuas ntau zaus thiab cov lus qhia tshwj xeeb sib xws ntawm cov teeb liab satellite raug xa mus.
Dab tsi yog qhov txawv ntawm ib qho kev taw qhia txuas txuas thiab lub splitter?
Thaum ob qho tib si directional couplers thiab splitters yog siv los faib cov teeb liab, directional couplers muab kev sib cais zoo dua ntawm cov tswv yim thiab cov chaw nres nkoj thiab tau tsim los tso cai rau cov teeb liab ntws mus rau hauv ib qho kev taw qhia. Splitters, ntawm qhov tod tes, faib cov teeb liab sib npaug ntawm cov chaw nres nkoj tso zis, uas tuaj yeem ua rau muaj teeb meem ntau dua thiab kev sib cais tsawg dua.
FAQ
Q: Dab tsi yog daim ntawv thov tseem ceeb ntawm CATV directional couplers?
A: CATV directional couplers yog siv rau cov teeb liab sib cais thiab sib txuas hauv cable TV faib tshuab. Lawv feem ntau ua haujlwm los faib cov xov tooj cua TV rau ntau lub TV lossis cov khoom siv hauv ib lub tsev lossis sib txuas cov teeb liab los ntawm ntau qhov chaw mus rau ib lub cable.
Q: Lub CATV directional coupler ua haujlwm li cas?
A: Ib qho kev taw qhia kev sib txuas sib cais lossis sib txuas cov teeb liab los ntawm kev tso cai rau lawv ntws feem ntau nyob rau hauv ib qho kev taw qhia thaum txo cov teeb liab poob ntawm qhov kev taw qhia. Qhov no ua rau cov teeb liab tau muab faib rau kev faib rau ntau yam khoom siv lossis ua ke los ntawm ntau qhov chaw mus rau ib lub cable.
Q: Dab tsi yog CATV directional coupler?
