Fiber Optic GSM CDMA WCDMA Repeater Digital truncking communication transmitter signal repeater

Product Description

Fiber Optic Repeater is designed to solve problems of weak mobile phone signal in such place: far away from the BTS (Base Transceiver Station) and has fiber optic cable network underground.

The whole FOR system consists of two parts: Donor Unit and Remote Unit. They transparently convey and amplify the wireless signal between the BTS (Base Transceiver Station) and mobiles via fiber optic cables.

The Donor unit captures the BTS signal via a direct coupler closed to the BTS (or via open air RF transmission through the Donor Antenna), then converts it into optic signal and transmits the amplified signal to the Remote Unit via fiber optic cables. The Remote Unit will reconvert the optic signal into RF signal and provide the signal to the areas where network coverage is inadequate. And the mobile signal is also amplified and re-transmitted to the BTS via the opposite direction.

Fiber optic Features:
1. High isolation full duplex design, Wave Division Multiplexing design, easy to install.

2. Low noise figure, high receive sensitivity.

3. With ALC and MLC function to ensure stable output power and easy installation and commissioning.

4. Scientific and perfect circuit design, and adopting advanced amplifier device, ensure the repeater station
equipment low power consumption, environmental protection and energy saving.

5. Modular structure design, according to need, easily to upgrade the system by increasing the module,
expand the business.

6. High Q cavity filter and SAW surface acoustic wave filter, high out of band rejection.

7. Adopt the world's most advanced high linearity, low intermodulation LDMOS power amplifier.

8. Perfect remote and local network monitoring function.

9. Waterproof design work for all weather indoor and outdoor.

Company Profile

ZD Telecom was newly established in Sep. 2009 by its founder who had been working in one of the earliest companies in the wireless/RF industry of China for more than 10 years of R&D and management after graduation from the best in China of“ University of Electronic Science & Technology of China”,with a back up of a group of veteran engineers cherishing the value of “professional(attitude) & excellent(products)”.

We are true manufacturer with a facilities of 2000㎡ and 150 heads of working force, not any of trading or solution provider companies, specializing in products of coverage/enhancement/optimization for wireless network and previously have been working as a role of OEM for some other big names of telecom equipment suppliers. We now step forward to the up front and devote to adheres to the business strategy of “customer oriented and continuous improvement”, and closely keeping to the principle of customer satisfaction, quality first, competitive price, fast delivery and service in individual place.

On the basis of such, we will continuously, as at our starting point, be striving to develop state-of-art products for the wireless telecommunication and antenna as our long run direction with our professional ability,rigorous attitude and standard of the line and enthusiasm and constant input of money for R&D.
With combined endeavours of years in this line,ZD has developed its own "RF passive products","Systemproducts"and the "The system structure" "Antenna"product line. Taking the advantages of China’s best supply chain of local industry as a plus, ZD is bracing up to become an important participator in the feeder antenna and the field of wireless network optimization equipment both in China and the outside world.
