Fiber Optic Rotary Joints

Product Introduction

Fiber Optic Rotary Joints (LPFO) are to optical signals what electrical slip rings are to electrical signals, a way to transfer signals through a rotating interface, especially when transmitting large amounts of data. JINPAT LPFOs maintain the inherent advantages of fiber end-to-end. JINPAT has been producing fiber optic rotary joints for over thirty years.


1. Single-mode fiber: core diameter is 9/125μm, suitable for long-distance, high-bandwidth transmission.

2. Multimode fiber: typical core diameter is 62.5/125μm or 50/125μm, suitable for short-distance transmission.

3. Common coaxial connectors: SMA, SMB, N-type, F-type, BNC, etc.
