Fiber-Optic Rotary Joint
Fiber-optic rotary joints (FORJ) for continuous optical transmission across rotating interfaces — single- and multi-mode, 1 to 5+ cores.
850–1550 nm
Operating wavelength
≤ 2 dB
Insertion loss · 1-core single-mode
≤ 2,000 rpm
Rated speed · 1 core
1 to ≥ 5
Fiber cores
Overview
Bandwidth that ignores EMI.
Low-loss optical transmission for high-speed data, imaging and communication systems. Fiber channels can share one assembly with power, Ethernet and coolant.
Design advantages
- Single-mode and multi-mode options
- 1-core, 2–4-core and 5+-core designs
- Immune to electromagnetic interference
- FC and SC connectors (others to order)
- Stainless steel housing
