Good Wholesale Vendors Internet Signal Repeater - Cost-effective Band Selective Fibre Optical Repeater VHF, UHF,TETRA BDA (DAS) for in-building wireless radio coverage – Kingtone

Short Description:

TETRA Fiber Optical repeaters consist of Master Unit (MU) and Remote Unit (RU). One Master Unit can work together with 1 to 4 Remote Units. The Master Unit transfers the BTS signal into optical signal and transmits the optical signal to the Remote Unit (RU). The Remote Unit (RU) transfer the optical signal into RF signal, amplify the RF signal and cover the target areas. The optical remote unit (RU) is connected to a master unit via optical fiber. The BTS signals are interfaced to the maste...

Good Wholesale Vendors Internet Signal Repeater - Cost-effective Band Selective Fibre Optical Repeater VHF, UHF,TETRA BDA (DAS) for in-building wireless radio coverage – Kingtone Detail:

The optical remote unit (RU) is connected to a master unit via optical fiber. The BTS signals are interfaced to the master unit for electrical/optical conversion. These converted signals are transmitted via optical fiber to the remote units and finally to the antenna. By utilizing optical fiber cables, high attenuation losses on long coaxial cables are avoided.
This increases the potential distance between remote unit and master unit up to 20 km. A subcarrier is fed into the signal path on the optical fiber to act as a remote control and supervision channel for all equipment. Due to the modular concept later expansion and upgrade is possible. System redundancy can also be provided at low cost impact.

• Cost-effective indoor cell enhancer
• Easy installation due to small dimensions and auto-gain functionality
• High reliability

Fibre-fed repeaters for two-way radio systems. Optical fibre solution for indoor coverage and range extension in VHF, UHF and TETRA frequencies.

This design distributed antenna system (DAS) for in-building wireless radio coverage.

Typical Applications:

TETRA Fiber Optical Repeaters are mainly used in indoor area and outdoor areas already with optic fibers. The application of Tetra Fiber Optical repeaters will effectively eliminate the signal blind areas, enhance the network quality, improve the image of cellular operators and bring them more profit.They are widely used in the places below.
