700 Series Fiber Optic Rotary Joint Assemblies

The 700 Series of fiber optic rotary joint (FORJ) assemblies support either single or multimode operation with options for wavelengths of 1310 or 1550 nanometers.

Both the 1310 and 1550-nanometer options feature an outer diameter of 7 mm for installation in tight spaces. Additionally, each FORJ assembly features an insertion loss of less than 2 decibels and a return loss greater than 30 decibels, making them ideal for high-speed digital transmissions over long distances.

Orbex FORJs support Ethernet, low-voltage differential signaling (LVDS), or high-definition multimedia interface (HDMI) protocols.

The FORJs are constructed of durable materials, including a stainless steel housing to ensure they perform well over their life cycle of over 200 million revolutions. For further environmental resistance, they are rated for both MIL-STD-810G impact force and MIL-STD-167-1A vibration protection.

Users can implement Orbex FORJs in areas with electromagnetic interference (EMI) due to their EMI immunity. The 700 Series is also IP67-protected and can withstand a temperature range of -40 to 80°C, allowing units to stand up to deep-ocean or arctic conditions.

The FORJs feature a fiber bend radius of over 25 mm and support a maximum operating speed of 2,000 rpm.

Units are UL Certified and meet APQP4WIND/Mil standard qualifications. Ideal applications include marine cable reels, wind turbines, robotics, and high-definition video transmission.
