Fiber optic rotary joint for marine applications GHS025-NF-01

for the aeronautical industryfor industrial applicationsfor wind turbine

Product Overview
The 8-Channel Fiber Optic Slip Ring (Fiber Optic Rotary Joint / FORJ) is a precision-engineered rotary transmission device designed for continuous 360° rotation while maintaining stable, low-loss optical signal transmission. It integrates up to 8 independent fiber optic channels in a compact housing, enabling simultaneous multi-channel data, video or sensor signal transmission without cable twisting. This model features single-mode fiber (9/125 µm), LC/PC connectors and armored 2.0 mm fiber pigtails for reliable performance in demanding industrial and field environments.

Key Features

• 8 Independent Optical Channels – Supports multi-signal transmission (data, video, control) in one compact unit
• Low Insertion Loss – ≤ 3 dB per channel, with stable variation ≤ ±0.20 dB
• High Durability – Rated for > 100 million revolutions service life
• IP65 Protection Rating – Dust-tight and protected against water jets, suitable for outdoor and harsh industrial use
• Wide Operating Temperature – -40°C to +85°C for extreme environments
• Compact Design – Space-saving footprint for integration into existing rotary systems
• Customizable Options – Channel count (2–10), connector type (FC/ST/SC/LC), fiber type (single-mode / multi-mode), cable length and jacket material available
