Fiber optic rotary joint (FORJ) also called fiber optic slip ring. Optic rotary joints FORJ help to transmit optical communication, like electrical slip rings are used to transmit electrical power and signals. FORJ provide a connection for uninterrupted transmission of optical signals across rotating interfaces. It is especially good for high speed data transfer on many applications. The key parameters are Insertion Loss, Insertion Loss Variation and Return Loss.
Fiber Optic Rotary Joints - CHG Series
Available for custom, can combine with electrical slip rings
Single or Multi-Channel
FORJs are available for single and multi-channel. Single channel FORJs allow single fiber in a system to carry large digital information. If more than two fibers are needed, GRAND offer a coaxial technology to make a reasonable cost solution.
Singlemode or Multimode
Singlemode fibers have small numerical aperture and core size with standard design to working at 1,310-1,550 nm wavelengths. Generally 0.5-1.0 dB insertion loss is acceptable. The bandwidth capacity is larger than multimode, since the optical beam is maintained in purest form.
Multimode fibers have large numerical aperture and core size with standard design to working at 850-1,300 nm wavelengths and transmit multi optical beams from VCSELs and LEDs. Multimode fibers are mainly used for short distance, since the higher attenuation and dispersion. However, singlemode systems are costly than multimode systems.
GRAND company is one of the world’s leading manufacturers of high performance fiber optic rotary joints. Optical slip ring parts are machined on precision machinery and optical slip ring assembly are manufactured in dustless workshop. The housing is made of stainless steel, dustproof and waterproof, reach IP68 protection grade, avoid influenced by humidity, heat, magnetism or other typical disturbances.
Although GRAND offer modularized & standardized design for various application solutions as an original slip rings manufacturer. To create your most suitable fibre optic rotary joint connector, please feel free to contact us.
