In addition to E. coli O157, many other  non-O157 STECs  also cause disease. Some  non-O157 STECs  cause disease that is often severe, resulting in bloody diarrhea and sometimes hemolytic uremic syndrome (HUS), which is a type of kidney failure.. coli can cause diarrhea, urinary tract infections, respiratory illness, bloodstream infections, and other illnesses. Other kinds of E. coli are used as markers for water contaminationâso you might hear about E. coli being found in drinking water, which are not harmful, but indicate the water is contaminated.
Fiber has many benefits over cable other than speed. Since fiber optic cables send data faster, theyâre better suited for long distance communication, which is why they power much of the internet. Theyâre also less likely to go out during a power outage as thereâs no electricity involved.
Each newer cable standard allows the user to get higher possible speeds with lower crosstalk. 1  This enables the user to get those fast speeds, even with longer cables. When compared at lengths of 100 meters of cable, the following numbers show the difference in Ethernet cable categories: 1  Cat5 ethernet cable is typically too slow for business networks, allowing the user to get up to 100 Mb/second speed at 100 Mhz. 2  Cat5e ethernet cable allows up to 1 Gb/s internet speed with 100 Mhz.
