Optical Fiber Feedthrough

Description

Optical Fiber Feedthrough for RF-Shielded Systems

The Optical Fiber Feedthrough provides a secure and reliable method for routing optical signals through shielded walls while preserving electromagnetic isolation. Designed for RF-sensitive environments, this component supports clean optical transmission without degrading shielding performance. Engineers rely on this solution when signal integrity and interference control are critical.

By combining optical connectivity with strong RF attenuation, this feedthrough supports demanding test, medical, and research environments.

Six-Channel Optical Design with High Shielding Performance

This feedthrough assembly includes six independent optical channels, allowing multiple fiber connections to pass through a single shielded interface. Each channel delivers up to 120 dB attenuation across a frequency range of 100 MHz to 15 GHz.

Because optical signals do not conduct RF energy, this design minimizes leakage while maintaining excellent isolation. As a result, sensitive systems can operate without external interference affecting measurements or performance.

Panel-Mount Integration and Installation Flexibility

The panel-mount configuration allows easy installation into a wide variety of shielded systems, including:

RF shield boxes
Shielded test enclosures
Anechoic chambers
MRI and medical imaging systems

In addition, the reciprocal filter design supports connectors on both sides of the panel. This flexibility simplifies cable routing and allows engineers to adapt the feedthrough to different layouts without redesigning the enclosure.

Compliance and Application Environments

This optical feedthrough meets MIL-STD-285 and MIL-STD-461 requirements, ensuring reliable performance in high-reliability environments. Because of this compliance, it is commonly used in:
