Light beam coupling in the stool core diameter, cross section
processing is simple, not easy to be broken is a special
performance, so the plastic optical fiber, plastic optical fiber
has become a popular choice for short distance communications. The
PJ2 type plastic optical fiber rotary joint provides two
independent fiber channels simultaneously. There is no blind spot
in the rotation process. It is the ideal choice in the mechanical
control system. The structural design of PJ2 allows it to work
underwater. Damaged plastic optical fibers are easy to repair
without replacing expensive PJ2..
Optical fiber rotary joint, also known as optical fiber slip ring
and optoelectronic shunt ring, uses optical fiber as data
transmission medium, providing the best technical solution for data
transmission between rotating connection system components. It is
especially suitable for applications that require unrestricted,
continuous or intermittent rotation, and also need to transfer
large capacity data from fixed position to rotary position.
