The glass fiber technology offers Single-mode (SM) and Multi-mode (MM) fibers.

While Multi-mode allows for carrying signals on many paths through the core fiber, Single-mode can carry only one single path, having the advantage of high-information carrying capacity and low attenuation. 

Single-Channel Multi-Mode

The single-channel Multi-Mode fiber optic rotary joint is suitable for the non-contacting bidirectional transmission of the highest data rates between a stationary and a rotating part. This unit is available for Multi-Mode glass fibers with fiber diameters of 62.5 to 125 µm and 50 to 125 µm. According to its optical features it is best suited for a wave range of 830 nm to 1,580 nm.
This multi-channel rotary joint will be delivered with a cable length of 2 m and is available with ST/PC or FC/PC connectors. Other customer specific mounting parts or different cable lengths are available upon request.

Typical applications:

• Industrial Applications
• Offshore and wind energy
• Military applications
• Surveillance
• Customer specific applications

Single-Channel Single-Mode

The base unit of the glass optical fiber technology is the single-channel fiber optic rotary joint for a non-contacting transmission of the highest data rates. This unit offers bi-directional data transmission between a stationary and a rotating part and is available for single-mode glass fibers with a fiber diameter of 9 to 125 µm. According to its collimation optic this unit is optimized for a wave range of 1,270 nm to 1,610 nm.
This single-channel rotary joint will be delivered with a cable length of 2 m and is available with FC/PC or FC/APC connectors.

Typical applications:

• Offshore equipment and wind energy
• Infra red surveillance systems
• ROVs (submarine and land)
• Military applications

Multi-Channel Multi-Mode

As well as the Multi-channel Single-Mode, the Multi-Mode design facilitates each data format and data protocol and may even be used for analog transmission. Furthermore, this unit is also suitable for the currently fastest common electronic transmission components.
Especially modern high-speed transmission systems benefit from this technology, which is best characterized by an extremely low insertion loss of max 3.5 dB at a wave length of 1,580 nm and a high back reflection of -20 dB.
The external dimensions without connecting cables add up to a total length of 155 mm at a diameter of only 60 mm.

Typical applications:

• Remotely Operated Vehicles
• Underwater applications
• Observation applications
• Industrial applications

Multi-channel Single-Mode (Micro-optic Rotary Joint)

This passive rotary joint unit facilitates each data format and data protocol and may even be used for analog transmission. It is suitable for the currently fastest common electronic transmission components.
The extremely low insertion loss of < 4 dB on the one hand and the high back reflection of -40 dB on the other hand form the basis of this technology in most modern high speed data transmission systems.

Typical applications:

• Remote Operated Vehicles
• Underwater applications
• Surveillance applications
• Industrial applications
