HELIOS's Fiber optic repeater system consists of two Units: Donor repeater and Remote repeater. Donor repeater is installed in BTS and Remote repeater is installed in remote cell site. Donor repeater captures RF signal and convert it into optic signal and transmit it to Remote repeater via fiber optic cable. Remote repeater reconverts the optic signal into RF signal and amplifies it by HPA. Fiber optic repeater is usually used outdoor since its output power is high.

Features:

1. Maximum transmission distance 20km by optical fiber cable.
2. Avoid co-frequency interference, omni directional coverage is possible.
3. Unlimited to the geography condition, especially applicable to remote towns and complex mountain regions.
4. Stable performance, sound coverage effect, easy to expand and maintain.
5. Improved system noise figure and sensitivity, provides wider coverage.
6. High out band rejection, excellent intermodulation and spurious emissions.
7. High gain linear power amplifier technique, with reliable performance.
8. Lightning proof and high voltage proof.
9. Compact design, water-resistant, weather-proof and antisepticise.
