Description
QYY- Fiber Optic Rotary Joints
Specifications：
Single or Multi-Channel：
. FORJs are available in single and multi-channel options. The most cost and size efficient options are the single and dual channel designs. If more than two fibers are present in a system, multiplexing solutions are avialable to combine multiple channels onto one or two fibers to allow the use of a one or two channel FORJ.
Single mode/multi-mode：
. Singlemode fibers allow the propagation of a single mode of optica energy due to their small core size and
small numerical aperture and for this reason they
