100Ohm CAT5/5e
一、 Applications
———————————————————————————————————————————————————————————————————————————
The frequency for the network communication of the rail transit is 100MHz. The cable is used for a large amount of data transmissions to meet the requirements of various internal control instruments and monitoring systems of passengers and vehicles. It features high-speed transmission and EMC optimization and can be used for low-smoke, halogen-free and flame-retardant rail transit.
