Model FO300

MULTICHANNEL FIBER OPTIC ROTARY JOINT (FORJ)

The FO300 is a prism-based multichannel 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.

The FO300 has three versions optimized to fit customer requirements in cost effective and compact package sizes:

Version A to support up to 17 channels
Version B to 32 channels
Version C to 52 channels
