Product Description
JARCH FORJ Miniature fiber rotary joints,6.8mm Micro optical fiber rotating joint

SF series Fiber Optic Rotary Joints (FORJs) are extremely compact. So small they can even be used in the middle of fluid flows. They are the world's smallest and lightest. They feature very low insertion loss and impressive return loss performance. Model SF typically yields return loss figures higher than 60 dB.

Dimension L To Be Advised When Ring And Current Details Are Options . Please Contact JARCH Technical Department,1000RPM M5 Connections Hybrid Slip Rings For Rotary Table or Industrial Machinery



Applications:

• Between in undersea robot and control ship

• Between in radar antenna and on-board signal processing system

• With the chariot rotating tower car body console

• Between in welding robot and console

• Remote mechanical input and output devices and control

• The photoelectric theodolite

• The connection between the platform and spacecraft tracking





Note: All insertion loss and return loss measurements are performed by joining the FORJ to the light source through fusion splice (without the use of connectors). Insertion loss of all receptacle type of FORJs, such as RST, RFC, and RFCX, are measured with connectors of similar type. Their return loss is not measured.
