Model FO319

FIBER OPTIC ROTARY JOINT

The FO319 is a non-geared, singlemode, compact two-channel fiber optic rotary joint (FORJ). It is a passive and bidirectional device which can be used as a standalone device or easily integrated into a rotary assembly, enabling transfer of high data rate optical signals across a rotating interface.
