The Fiber Optic Benefit

A fiber optic connection is extremely secure and immune to RF and EM interference ensuring reliable and industrial grade performance when it comes to signal integrity and offers future proofing solution for years to come. 


Ideally, fiber-based transmissions are the most reliable and secure method of delivering digital HD video, audio, data over long-haul fiber optic cables mainly deployed in government, command and control systems and digital signage applications where security and high-resolution imagery is critical for day to operations without any signal downtime or degradation.
