FRMM-K Fiber Optic Rotary Joint

Product Introduction

The FRMM-K fiber optic rotary joint is an axial compact multi- channel fiber optic slip ring, with a total length of only 96.5mm and up to 12 channels can be achieved. It can be selected as single- mode, multi-mode or single/multi-mode hybrid, and products with environmental resistance (shock, vibration, high and low temperature) levels are also available for selection.
