Yam ntxwv ntawm Tooj Media

Txawm li cas los xij, tooj liab media yog txwv los ntawm kev ncua deb thiab teeb liab cuam tshuam. Cov ntaub ntawv yog kis rau tooj liab kab raws li hluav taws xob pulses. Ib tug ntes nyob rau hauv lub network interface ntawm lub lo lus uas peb ntaus ntawv yuav tsum tau txais ib lub teeb liab uas yuav tau ntse decoded kom phim lub teeb liab xa.

Ib yam li ntawd, nws yog nug, hom ntaub ntawv twg yog kis los ntawm ib tug tooj liab cable?

Tooj liab siv hluav taws xob teeb liab kom dhau cov ntaub ntawv nruab nrab ntawm tes hauj lwm. Muaj peb hom tooj liab kab : coaxial, unshielded twisted khub thiab shielded twisted khub. Coaxial degenerates dhau nyob deb. Unshielded twisted khub yog ua los ntawm twisting lub tooj liab kab ib ncig ntawm ib leeg thiab qhov no txo qis degeneration.

dab tsi hloov tooj liab hlau nyob rau hauv kev xa cov ntaub ntawv hauv computer? fiber optics zoo hloov tooj liab hlau nyob rau hauv cov xov tooj nyob deb deb, thiab nws yog siv los txuas khoos phis tawj nyob rau hauv lub zos cheeb tsam network. Fiber optics kuj tseem yog lub hauv paus ntawm cov fiberscopes siv los tshuaj xyuas qhov chaw hauv lub cev (endoscopy) lossis tshuaj xyuas cov khoom siv sab hauv ntawm cov khoom tsim.

Ua raws li qhov no hauv kev txiav txim siab, dab tsi yog qhov kev sib kis ceev ntawm cov tooj liab cable?

Cat 6 tooj liab kab muaj qhov siab tshaj plaws bandwidth ntawm 1 Gb / s, thaum Cat 5e tooj liab kab tshaj tawm ntawm 100 Mb/s.

Qhov tooj liab cable yog dab tsi?

Tooj kab thiab kab . A tooj liab kab yog ib pawg ntawm ob lossis ntau dua cov kab tooj liab bundled ua ke nyob rau hauv ib tug sheath los yog lub tsho. Tooj kab thiab kab yog siv rau hauv kev tsim hluav taws xob, kev xa hluav taws xob, kev xa hluav taws xob, kev sib txuas lus, hluav taws xob hluav taws xob, thiab ntau yam khoom siv hluav taws xob.
