Splitter - xal casri ah oo shabag laanta

xawaaraha internet banki iyo awood u leh inay kala soo bixi xogta aan xad lahayn. Xidhiidhinaya network waa via cable telefoonka landline ah, iyo haddii aadan u baahan tahay dambaysta ah, ka dibna ay dhibaato kaa haysato ma kici doona. Si kastaba ha ahaatee, marka ay u baahan yihiin xiriir ah oo deggan internet oo link cad on telefoonka, waxaa lagama maarmaan ah in la isticmaalo splitter ah. Qalabka waxa lagu abuuri doonaa calaamad cad oo deggan labada khadadka.

description

Splitter - qalab is haysta elektaroonik ah, shaandhayso digital calaamadaha la firikuwensiyada kala duwan. qalab soo bandhigay kuu ogolaanayaa inaad in ay ku xidhmaan noocyada kala duwan ee qalabka in mid ka mid ah khadka coaxial. Tusaale ahaan, TV iyo modem.

Qaab ahaan, waa isku xira ah oo ku qalabeysan yahay dekedaha badan in ay ku xidhmaan qalabka. Beegyada uu ugu weyn in sifaha splitter ah - tiro ka mid ah Xidhiidhiyayaasha xirashada qalabka. Tiradoodu kala duwan tahay 2 ilaa 16 ama ka badan. The dekedaha dheeraad ah, qalabka waxaa loo arkaa functional.

Waxaa intaas dheer in qalabka caadiga ah, suuqa ka heli kartaa version a xoog of splitters ah. Waxyaabahani waxaa lagu kala isku mar xoojin signal ee gudbinta ka badan masaafo dheer, taas oo ku haboon ay ka maqan yihiin fiber optic-ga.

technology

ADSL (sinnayn Digital macmiilka Line) - technology, kuwaas oo ka hawlgala splitter ah. Waxaa suurto gal ah si loo gaaro gudbinta xogta xawaaraha sare iyo soo dhaweynta ee khadadka telefoonada macmiilka ee shabakadaha dadweynaha. Qulquli heerka safafka macluumaad qaybinta:

• ka 128 kbit / s iyo 8Mbit / s u helo xogta user;
• ka 64 kbit / s 1 Mbit / s for gudbinta macluumaad user.

Inta lagu jiro hawlgalka, qalabka dhunsan calaamadaha ee telefoonka iyo internetka Moodeemka. durdurrada Data kala duwan yihiin inta jeer: line telefoonka waa dabeecadda u ah dhamaan 0,3-3,4 Khz, halka shabakada soo dirayaa warbixin la soo noqnoqoshada ah MHz 0,26-1,4. Tani waxay gabi ahaanba ma baabiin karta saameynta ay labada dhinac ka mid ah qalabka ku kasta oo kale ee shaqada.

Intaa waxaa dheer, splitter splitter sii midaysan ilaalinta noocyada kala duwan ee hadda iyo wixii dhaawici kartaa unugga. Marka firfircoonaan, shabakadda ma noqon karaan garaaca wadnaha overvoltage cabsan dhaca inta lagu jiro onkodka, circuit gaaban, baadhayo hadda line gudbinta.

Qalabka TV

Oo ay la socoto hab of calaamadaha kala internetka iyo telefoonka isticmaalaa splitters loogu talagalay qalabka network television. Waxay yihiin couplers caadiga ah in ay isku qaybiyeen dhexeeya qalabka signal kala duwan. The laamood dheeraad ah oo ka soo xira ah, taagta daran ee lagu baahin doonaa hal "sanduuqa" kasta.

Inta badan, splitter ah TV-ga waxaa loo isticmaalaa in lagu xiro qalabka kala duwan si ay u antenna hal, aqbalana satellite. Laakiin isku halleeya oo qiimihiisu yahay qalab la dhisay-in kordhiyo signal, haddii kale is tayada image ma noqon doonto mid suurto gal ah.

splitters kala duwan

Its Tilmaamo gaar ah waxaa la bixiyaa in kasta oo splitters ah. Waxay ku xiran tahay technology kaas oo la soo saaray by splitter ah. Tani waxay keenaysaa in laba nooc oo aasaasi ah:

• PLC-qalabka la hirarka raadiyaha ka shaqeeyaan kala duwan ka soo 1260 si ay u 1650 nm, kaas oo u ogolaanaya si ay u isticmaalaan inta badan shabakadaha casriga ah.
• FBT-qalabka awood u siman qaybinta signal a in ilo kala duwan.

Si aad u doorato qalabka saxda ah ee network, aad u baahan tahay in ay diiradda saaraan laba koobin. The ugu horeysay oo ka mid ah - waa inta jeer signalka looga baahan yahay hawlgalka ee qadanayo ah. Waa lagama maarmaan in splitter shaqeeyay kala duwan oo la mid ah.

wax labaad ayaa u baahan fiiro - waa heerka uu attenuation of signal la tilmaamay on set telefishanka iyo qalabka kale. The hoose qiimaha, xoog gudbinta. Xaaladdan oo kale, baahida loo baabi'i doontaa in kordhiyo splitter dhisay-in.

xeerarka la xidhiidha

In mid noqoshada qaybiye ee shabakadda ee ma aha arin wayn. First xirmaan fiilada talooyin iyo Xidhiidhiyayaasha in branching waa fiilooyin xiran oo keeni qaateyaasha kala duwan. Laakiin si loo hubiyo in farsamada waa cad iyo signal deggan, waxaa lagama maarmaan ah si ay u dhawraan labada xeerarka:

1. Dhaqangelinta splitter antenna hore ee qalabka firfircoon.
2. Ha jaray laba splitter ah.

Haddii ka dib markii xira TV si image splitter la kala qaybsamo laba, inta u dhaxaysa cable iyo isku xira waa rakibi giraanta ferrite.
