Ziboda - njira zamakono kwa maukonde nthambi

liwiro basi anatumizanso lamya intaneti ndi luso download deta malire. Kulumikiza kwa maukonde ndi kudzera ndi chingwe landline foni, ndipo ngati safuna otsiriza, ndiye inu muli mavuto osadzuka. Komabe, pamene ayenera khola intaneti ndi kugwirizana bwino pa foni, m'pofunika ntchito ziboda. chipangizo ichi adzalenga bwino ndi khola chizindikiro mizere onse.

mafotokozedwe

Ziboda - yaying'ono amagetsi chipangizo, zosefera digito zizindikiro ndi mafurikwense osiyana. Anapereka chipangizo limakupatsani kulumikiza ku mitundu angapo zida mmodzi wa mzere coaxial. Mwachitsanzo, TV ndi modemu.

Amapanga, ndi cholumikizira amene okonzeka ndi madoko angapo kulumikiza zipangizo. Magawo zazikulu zomwe ziboda - angapo zolumikizira kwa polumikiza zipangizo. chiwerengero chawo zimasiyanasiyana 2 16 kapena kuposa. Madoko zambiri, chipangizo imatengedwa zinchito.

Kuwonjezera zida muyezo, msika mungapeze mphamvu buku la ziboda za. mankhwala amenewa anasiyanitsidwa ndi imodzi azimveka otsogolera kufala pa mtunda wautali, umene uli yabwino, pakalibe zingwe CHIKWANGWANI-chamawonedwe.

umisiri

ADSL (asymmetric Intaneti Line wolembetsa) - luso, amene umagwira ntchito za ziboda. N'zotheka kukwaniritsa liwilo deta HIV ndi phwando mu mizere wolembetsa telefoni pa Intaneti anthu. Ikuyenda mlingo mudziwe kugawa ranges:

• kuchokera 128 kbit / s ndipo 8Mbit / s kulandira deta wosuta;
• kwa 64 kbit / s 1 Mbit / s kwa kufala kwa mudziwe wosuta.

Pa ntchito chipangizo mitundu ya chizindikiro foni ndi Intaneti modems. Data mitsinje zosiyanasiyana pafupipafupi: mzere telefoni ndi khalidwe onse kHz 0,3-3,4, pamene maukonde amatumiza mauthenga ndi pafupipafupi 0,26-1,4 MHz. Izi akhoza bwinobwino kuthetsa kukopa tonse zipangizo pa ntchito ya wina ndi mzake.

Komanso, chiboda ziboda zina Integrated chitetezo zosiyanasiyana panopa ndi amene angathe kuwononga unit. Pamene adamulowetsa, maukonde akhoza Usaope overvoltage zimachitika zikuchitika pa thunderstorms, dera lalifupi, kusanthulasanthula kufala mzere mafunde.

Zipangizo TV

Pamodzi ndi njira ya chizindikiro kulekana kwa Internet ndi foni amagwiritsa ziboda anafuna chipangizo TV maukonde. Iwo couplers wamba amene uniformly anagawira pakati pa zipangizo zosiyanasiyana chizindikiro. nthambi zambiri kuchokera cholumikizira, ndi ofooka adzakhala ukufalitsidwa pa umodzi uliwonse "bokosi".

Nthawi zambiri, ziboda kwa TV ntchito kulumikiza zipangizo angapo mlongoti limodzi, Kanema wolandila. Koma kukhulupirirana wokwanira chipangizo ndi anamanga-mkuzamawu chizindikiro, kapena china Pezani chithunzi khalidwe liti sizingatheke.

mitundu ziboda

mbali yache zoperekedwa aliyense ziboda za. Iwo amadalira luso limene anali opangidwa ndi ziboda za. Zimenezi zimabweretsa mitundu zofunikira ziwiri:

• PLC-zipangizo ntchito ndi mphepo mu osiyanasiyana kuchokera 1260 mpaka 1650 nm, amene amalola ntchito zawo Intaneti zambiri zamakono.
• FBT-zipangizo angathe wogawana kugawira mbendera magwero angapo.

Kusankha chipangizo chabwino kwa maukonde anu, muyenera kuganizira magawo awiri. The woyamba - ndi pafupipafupi chizindikiro chofunika ntchito za wolandila lapansi. M'pofunika ziboda ntchito mu osiyanasiyana chomwecho.

Chinthu chachiwiri chimene osayenera - ndi digiri ya attenuation cha chizindikiro imaonekera pa TV ndi zipangizo zina. M'munsi mtengo, mphamvu ndimakokedwe. Pankhaniyi, kufunika idzapita mu anamanga-ziboda mkuzamawu.

malamulo mogwirizana

Mu wogawira mupezeke maukonde palibe lalikulu zambiri. Choyamba kulumikiza athandizira chingwe ndi zolumikizira kuti nthambi ya m'pamene mawaya chopatsa amalandira osiyana. Koma kuonetsetsa njira ndi yomveka ndi chizindikiro khola, m'pofunika kutsatira malamulo awiri:

1. Kukhazikitsa mlongoti ziboda kutsogolo zida yogwira.
2. Musati interconnect awiri ziboda.

Ngati kulumikiza TV kwa ziboda chithunzi ng'ambidwa awiri, pakati pa chingwe ndi cholumikizira ayenera kukhazikitsa mphete ferrite.
