Fiber optic waveguide, also known as a cutoff waveguide, acts as a high-pass filter for electromagnetic waves. Primarily used for shielding treatment of fiber optic cables and various pipes entering/exiting shielded rooms.

Structural Characteristics
● Waveguide aperture is generally within 12mm, or can beadjusted appropriately based on different requirements.
● The waveguide is fixedly welded at designated positions onthe shielded room enclosure.
● Fiber optic waveguides are installed at the fiber optic cable orfiber entry points using a welded structure.
Main Functions
● Used for fiber optic entry/exit, air conditioning pipeentry/exit, floor drain drainage, fire protection pipes, etc.,in shielded rooms.
Test Standards
● Meets national confidentiality and military standard-relatedstandards.
Shielding Characteristics
● The waveguide has a defined cutoff frequency. When thefrequency of an electromagnetic wave is below this cutofffrequency, the wave cannot pass through the waveguide,thus the waveguide acts as a shield.
● Shielding effectiveness is consistent with the overalleffectiveness of the shielded room.
