Critical Communications


RLH fiber optic links are commonly utilized in public and private networks to not only extend the reach of existing copper networks, but provide critical always-up network reliability. Fiber optic links can extend the network up to 36 miles over fiber optic cable without the need of repeaters. This keeps equipment count low and reliability high.

If the network malfunctions due to environmental factors such as chemical reactivity or corrosion due to high moisture, electromagnetic or radio frequency interference, or the presence of high voltage power surges or ground potential rise, then the systems that rely on those communications may be compromised. By using all-dielectric fiber optic cable instead of copper, these factors that affect network reliability can substantially reduced or eliminated.

Advantages of Fiber Optic Transmission Technology

  • Immunity to EMI/RFI and lightning damage
  • Low attenuation (data loss)
  • Small fiber cable has high bandwidth
  • No sparks if cut – ideal for hazardous areas
  • Secure communication
  • Corrosion resistant and chemically non-reactive
  • Future expandability

An important factor in with industrial network components, is that the equipment must be capable of withstanding harsh environmental conditions such as extreme temperature ranges, lightning strikes, Ground Potential Rise (GPR) events and power surges.

RLH industrial-hardened analog and digital copper to fiber voice/data equipment provides isolation from environmental and outside disturbances in environments ranging from –40°C ~ +70°C.

RLH manufactures fiber optic links for all types of Telco services. Contact us today for a solution that fits your needs.
