MJX series Fiber Optic Rotary Joints (FORJs) are extremely compact. So small they can even be used in the middle of fluid flows.
They are the world's smallest and lightest. They feature very low insertion loss and impressive return loss performance.
Model MJXA guarantees return loss as high as 50 dB.
The standard packages are dust and water tight for harsh environment applications. They are designed to
tolerate both occasional water splash and shallow water (or oil) immersion.
These rugged devices can operate under arctic temperature environment (See insertion
loss temperature cycling plot on the left).
