My desk is surrounded by cables of all types. Cat-5s / Car-5 abound. One thing I have noticed is that some of these cables have been here for the 14 years I have been in these offices. That speaks well to using cables that are made to spec and optimized for the particular usage.
It is for this reason and many others that companies like Optimized Cable Company should be the effective choice for cable needs. A company must offer choice and a degree of technical ability to win over said business.
I just decided to take another look at the site and it simply seemed that the choices are ever expanding. That speaks well for longevity. That is something one wants for consistency in supply.
