Eriri-optic cable - a iche iche ụdị cabling media

Iji ụbọchị, eriri optic cable bụ a pụrụ iche ụdị na cable gburugburu ebe obibi. Dị ka ihe ndị bụ isi mmewere sikwa iko, ikwe na-ekesa ozi ihe karịrị anya na-enweghị ịrịba ọnwụ nke na-agba. Nnyefe na nke a rụrụ bụghị site electric mgbaàmà, na ekele ìhè usu, nke na-enyere na-enye a elu mkpọtụ ọgụ na nche nke-ebute site ná ọmụma. Otú ọ dị, echichi nke eriri optic cable emepụta isi ike ụfọdụ n'ihi na ọ na-achọ n'oge echichi nke njikọta micron ziri ezi. Site na nke a ga-eme ka na-adabere attenuation usoro.

A, na-ebikwasị eriri-optic cable na-eme aka ma ọ bụ na ihe pụrụ iche winches. Na usoro nke na-arụ ọrụ ga-gaa na akaụntụ a ọtụtụ ihe ndị pụrụ imetụta ihe ga-esi. Mgbe Ịtọ pụrụ iche ngwa ga-eji na-enyere belata esemokwu ọnụọgụ na izere mmebi nke ekwe ebe. Tightening a rụrụ na winches, ikpebi traction. Ná ngwụsị nke cable olulu ekpe oke maka USB igbe.

Ọ bụla eriri optic cable nwere ike ịbụ otu mode ma ọ bụ multimode. Ke akpa idaha, niile ụzarị merie otu ụzọ na-eru erite n'out oge.
