Introduction:
CJ-TF series TTL/HTL fiber optic converter transmit
TTL/HTL signal through the optical fiber with long distant
transmission. Due to the use of optical fiber communication,
its can solve the electromagnetic interference, ground loop
interference and the lightning damage, greatly improve the
data communication reliability, security and confidentiality.
Its can be widely used in various industrial control, process
control and traffic control occasions, especially suitable for
oil, ports, electricity, transportation, mining and energy
industries.
