Princetel Component
Ultra Low Reflection Fiber Rotary Joints (MJP series)
Non-fluid-filled single-channel FORJs with return loss >55 dB (MJPP >60 dB), low start-up torque and high speed, for OCT applications.
Description
The MJP series is not fluid filled and offers very high return loss (>55 or >60 dB), lower start-up torque and high-speed rotation, suited to optical coherence tomography (OCT). It accepts custom fibers with cladding diameters above 125 um. Gear-drive and belt-drive versions with SC/APC receptacle are offered. It has a stainless steel housing measuring 17.0 mm dia. x 48.5 mm length, weighs ~85 g and meets MIL-STD-167-1A vibration and MIL-STD-810G shock requirements. Pressure compensation is not offered; the page refers to the RPC series for that.
## Key features
- Insertion loss: <2 dB (typical: <1 dB)
- Return loss (SM): >55 dB (MJPP: >60 dB)
- Maximum speed: 10,000 rpm
## Applications
- Optical coherence tomography (OCT) systems
- High-speed rotating fiber links requiring low back reflection
