UTP (Unshielded Twisted Pair) : Cov hlua khau tsis zais tsis muaj hlau thaiv, tsuas yog ib txheej ntawm cov roj hmab insulating qhwv, nws lub voj voog kom zoo dua cov nplaim hluav taws zoo, tsis yooj yim rau hluav taws. Pib unshielded twisted nkawm Cat5e, Cat6, Cat6A hlau outsourcing yog zoo nplhaib nplhaib retardant PVC sheath, lub neej ntev kev pab.
STP (Shielded Twisted Pair) : Cov khoob khawm khau khau, qhov no yog lub npe dav.
FTP (Foiled Twisted Pair) : Txhuas cov ntawv ci thaiv shielded twisted nkev hlau, tam sim no shielded twisted khub network cable yog daim ntawv txhuas ntawv thaiv cov hlua khau cov xov hlau. Yog li STP thiab FTP yeej zoo li qub. Piv rau UTP, FTP / STP tsuas muaj ib txheej txheej ntawm cov ntawv txhuas ntawm sab nraud ntawm cov tub ntxhais kom txo cov teeb liab zig. Pib txhuas ntawv thaiv shielded twisted nkawm Cat5e, Cat6, Cat6A cables ua qhov kev tshuav nyiaj li cas ntawm tus khub kom ruaj khov.
SFTP : Ob-shielded twisted khub. Cov qauv ntawm cov hlau no yog raws li cov ntawv txhuam ntawm FTP / STP thiab ib txheej ntawm tinned copper woven mesh. Cov txheej txheem sab nraud yog PVC txheej npog. Vim yog qhov sib ntxiv ntawm lub tinned tooj liab woven mesh, sab nraud magnetic teb thiab teeb liab cuam tshuam tau raug txo kom tsawg, thiab qhov kev hnov ntawm lub teeb liab yuav raug txo kom tsawg, thiab lub zog qeeb ntawm cov hlua yuav tau nce. Starte Cat5e outsourcing single-sided aluminium ntawv + woven mesh ob lub tiaj tiaj shielding txheej tau zoo thaiv lwm tus electromagnetic cuam; thickened aluminum ntawv thaiv shielding txheej +128 woven mesh ntawm siab shielded twisted khub Cat7 network hlau tau zoo thaiv crosstalk thiab sab nrauv electromagnetic yoj cuam tshuam.
