Malo okhala m'nyanja amachititsa kuti zingwe za Ethernet zisagwidwe ndi kusokonezedwa ndi magetsi (EMI) komanso zinthu zina zovuta. Kusankha njira yoyenera yotetezera magetsi ndikofunikira kwambiri pakulankhulana kodalirika.
Ma model a chingwe cha Ethernet chamadzi wamba amaphatikizapo zambiri zokhudza kuwerengera, kapangidwe, ndi zipangizo. Chitsanzo: Cat 5e F/UTP, 4×2×24 AWG, LSZH imasonyeza chingwe cha Gulu 5e chokhala ndi kondakitala wa 24 AWG, chishango chonse cha Aluminium Foil Mylar Tape, ndi chidebe cha zero-halogen chotsika utsi. Pano, F/UTP ikuyimira mtundu wa chishango.
Zingwe za Ethernet zimapezeka m'njira zosiyanasiyana zotetezera. Mitundu yodziwika bwino:
Peyala Yopindika Yosatetezedwa (U/UTP)
Palibe chitetezo cha munthu aliyense payekha kapena chonse, kudalira kusinthasintha kwa awiri kuti achepetse kusokonezeka. Ubwino wake ndi monga mtengo wotsika komanso kulemera kopepuka. Komabe, U/UTP nthawi zambiri siilimbikitsidwa pa ntchito zambiri zapamadzi chifukwa cha EMI yofala. Ikhoza kuganiziridwa kokha pamayendedwe afupiafupi komanso olekanitsidwa mkati mwa malo oyera komanso otetezedwa.
Chishango Chonse Chokhala ndi Zojambula za Aluminium Mylar Tepi (F/UTP)
Tepi ya Mylar ya Aluminium FoilImazungulira mawiri onse awiri, kupereka chitetezo chogwira ntchito bwino kwambiri. Imapereka ndalama zokwanira komanso magwiridwe antchito abwino pa ntchito zonse zapamadzi ndi zamafakitale. Kugwiritsa ntchito tepi yapamwamba kwambiri ya Aluminium Foil Mylar kumatsimikizira magwiridwe antchito okhazikika achitetezo.
Chofunika Kwambiri: Waya wothira madzi uyenera kukhazikika bwino kuti chitetezo chikhale chogwira ntchito. Kukhazikika koyipa kungapangitse kuti chitetezo cha foil chisagwire ntchito kapena chikhale chovulaza.
Chishango Chonse Chokhala ndi Zojambula za Aluminium Mylar Tepi + Choluka cha Mkuwa Chothira (SF/UTP)
Kuteteza zinthu ziwiri kumaphatikiza thonje ndi mkuwa wokulungidwa, zomwe zimapangitsa kuti EMI/RFI isagwire bwino ntchito. Kuluka kwa mkuwa kokulungidwa kumapereka chitetezo chabwino kwambiri cha low-impedance komanso chitetezo chapamwamba cha maginito chotsika (chomwe thonje lokha silingathe kuchita), komanso chitetezo chamakina. Ndikoyenera kwambiri malo ovuta a ziwiya za m'thupi.
Chishango cha Payekha Chokhala ndi Tepi ya Aluminium Foil Mylar ndi Chishango Chonse Chokhala ndi Chikopa cha Mkuwa Chokutidwa (S/FTP)
Gulu lililonse lili ndi chitetezo chapadera cha foil, komanso ulusi wa mkuwa wopangidwa ndi chitini. Kapangidwe kameneka kamachepetsa kulumikizana pakati pa awiriawiri pomwe kamachepetsa kusokoneza kwakunja, zomwe zimapangitsa kuti chitetezo chizigwira ntchito bwino pa ma frequency ambiri. S/FTP ndi yoyenera malo okhala m'nyanja omwe ali ndi zofunikira zambiri za EMC.
Chishango cha Payekha Chokhala ndi Cholembera cha Aluminium Chokha Chokhala ndi Tepi ya Mylar (U/FTP)
Gulu lililonse lili ndi chitetezo chake cha foil, koma palibe chishango chonse. Choyamba chimachepetsa kulankhulana pakati pa awiriawiri, koma chitetezo ku kusokonezedwa ndi zinthu zakunja chimakhala chochepa. Nthawi zambiri chimagwiritsidwa ntchito m'malo okhazikika monga zipinda zamagetsi. Posankha chingwe cha m'madzi, njira zotetezera zonse nthawi zambiri zimakhala zabwino, zomwe zimapangitsa kuti U/FTP ikhale yosazolowereka.
Chishango cha Payekha ndi Chishango Chonse Zonse ndi Aluminium Foil Mylar Tepi (F/FTP)
Kapangidwe ka zojambula zonse kuphatikiza chitetezo cha zojambulazo payekha komanso chonse. Popanda wosanjikiza wolukidwa, magwiridwe antchito motsutsana ndi kusokonezedwa kwa maginito kochepa ndi ochepa. Komanso zimakhala zovuta kuzithetsa modalirika m'malumikizidwe oyikidwa m'munda chifukwa cha zojambulazo zofooka. Chifukwa chake, F/FTP sigwiritsidwa ntchito kawirikawiri m'magwiritsidwe ntchito am'madzi poyerekeza ndi S/FTP kapena SF/UTP.
Kapangidwe koyenera ka chishango ndikofunikira kwambiri kuti chingwe cha Ethernet chikhale chokhazikika komanso chodalirika. Kusankha njira yoyenera yotetezera kutengera malo omwe amagwiritsidwa ntchito komanso mulingo wa EMI kumathandizira magwiridwe antchito onse a makina olumikizirana.
DZIKO LIMODZIYadzipereka ku kafukufuku ndi chitukuko ndi kupereka zipangizo za chingwe. Timapereka zipangizo zotetezera kuphatikizapo Aluminium Foil Mylar Tepi, tepi ya combined ya mkuwa ndi pulasitiki, ndi waya wamkuwa wopangidwa ndi zitini kuti apange zofunikira zosiyanasiyana zotetezera. Timapereka chithandizo chokhazikika komanso chodalirika cha zinthu zosiyanasiyana zotetezera, kuthandiza makasitomala kuti akwaniritse ntchito yabwino kwambiri ya chingwe.
