Medical imaging applications such MRI, CAT scan, PET or X-ray use very high voltages to power transmit coils or X-ray tubes. Significant electromagnetic interference (EMI) is generated in the medical equipment environment so medical imaging designers look to fiber optic transmission media to protect patients and equipment against the effects of these unwanted signals. For the transmission of control signals to motors or transmitting coils, Firecomms DC-1 MBd or DC-5 MBd transmitters and receivers are widely used with Plastic Optical Fiber (POF) and Plastic/Polymer Clad Silica (PCS) fibers to galvanically isolate the transmission while providing immunity from EMI. Higher speed Firecomms DC-10 MBd or DC-50 MBd fiber optic transceivers are equally suited to MR magnet, patient table motor, or gradient control systems.
As it is advantageous to digitize the RF signal received in imaging applications directly in the coil to enhance the signal-to-noise ratio (SNR) of the received images, Firecomms has custom designed non-magnetic fiber optic transceivers to operate within the strong magnetic fields of MR and imaging equipment. Our range of transceivers that operate at 125 MBd or 250 MBd data rates are suitable for this purpose. Taking it a step further, Firecomms Gigabit transceivers allow the aggregation of multiple data streams from the RF coils to be transmitted to the control room for data processing. Utilizing optical cables for this purpose also provides the advantage of considerably reducing the number and cost of bulky RF cables. Patient monitoring equipment, such as video cameras, linked with fiber optic cables prevents patient injury within the coil. Firecomms Gigabit Ethernet transceivers are available in non-magnetic packages to protect against these occurrences.

Firecomms products with Plastic Optical or Plastic Clad Fiber (POF/PCS) links offer many advantages in medical imaging applications:
Medical robots place some of the highest demands on signal integrity, flexibility, sterility, and safety. Traditional copper cabling introduces challenges: electromagnetic interference, bulky harnesses, limited bending life, and galvanic coupling risks.
With proven tolerance to repeated motion, intrinsic EMI immunity, and galvanic isolation, our solutions enable scalable, high-bandwidth, ultra-reliable links through robotic joints, arms, and sensor chains. Whether you’re streaming high-definition endoscopic video, coordinating multi-axis servo control, or integrating force/torque sensors, our optical communications backbone offers a robust, medically compatible foundation for next-generation robotic systems.
Optical communication, especially through POF, enhances the performance and reliability of medical robots across various applications. In surgical arms, flexible fiber cabling efficiently transmits control and sensor data while reducing noise, bulk, and component count. Imaging robots benefit from high-speed, interference-free data transfer for endoscopic and microscopic systems, while non-metallic fibers enable safe use near MRI and CT equipment. Rehabilitative and assistive robots rely on POF’s resilience to repeated motion and bending, maintaining signal integrity during patient interaction. Even hospital logistics and sterilization robots use optical links to ensure reliable communication in humid, high-temperature, or chemically exposed environments, making fiber-based connectivity a cornerstone of modern medical robotic systems.
Medical robots demand exceptional signal integrity, flexibility, sterility, and safety, but traditional copper cabling often falls short due to EMI, bulkiness, limited bending life, and galvanic coupling.
Optical fiber (especially POF) overcomes these limits by offering:
