This 20m black Cat6 patch cable is part of the Dynalink patch cable range and offers better signal to noise ratio with minimal loss in modern networks requiring speeds up to 10GBASE-T (10 Gigabit) ethernet speeds. The range has been designed to be compliant to the latest standards and are manufactured to a very high standard, passing rigorous testing procedures. Category 6 cables, commonly called "Cat 6" are backward compatible with older data cable standards such as Category 5 and 5e. These cables have been designed to prevent crosstalk between pairs and reduced system noise. This allows it to achieve higher speeds than the older standards up to 10 Gigabit.
