SFNT unmanaged switches operate across a wide temperature range, making them suitable for harsh environments. The switches are the latest addition to the Standard Function Narrow (SFN) line of unmanaged switches. The SFNT switches can operate between minus-40 and 75 degrees Celsius. They also meet the increased noise immunity, shock and vibration standards necessary to operate in extreme environments. Five- and eight-port versions are available for 10/100 mbps, as well as multimode fiber with SC and ST connections.
