2G/3G/4G/5G (BDA) Optical Repeater 

The system consists of two parts: Master Unit (MU) and Remote Unit (RU). The MU captures the Base Station signal via direct coupler close to Base Station, then converts it into optic signal and transmits the amplified signal to the RU via fiber optic cable. The RU 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 retransmitted to the Base Station via the opposite direction. 

. Support for 10MHz - 6000MHz Bandwidth

. Up to 8 BiDi to connect remote unit

. Support for monitor and manager

Cellular Repeater (BDA) Manager System

The distributed antenna system (DAS) is a communication solutions which is used to distribute the cellular signal of operators within a building with cellular RF over fiber (RFoF) for the indoor environments.  The RFoF transceivers can convert analog RF signals to fiber optic signals on both master and slave units, support for controls 8 remote units via a RFoF (TPRF-2F628-M8).


Generally, the BDA management systems can be through the optical fiber(SMF) from master unit to remote unit, that can monitor the RFoF (TPRF-2F628-M1), amplifier and the BDA in the BDA/DAS systems, uses RS232/RS485 to connect PCBA to BDA. It's enable to uses a 433MHz or 866MHz analogue RF signals input laser to control remote devices.


Optical BDA management function:

. Power alarm,
. Temp alarm,
. Laser alarm,
. PD alarm,
. RF on/off,
. Gain adjust.

2G 3G 4G 5G Cell phone signal management systems in privacy area

This is an intelligent management system with low radiation, full frequency range, precise positioning, intelligent adaptation, etc., which can improve security measures and avoid the harm of illegal mobile phone intrusion. Establish a mobile intelligent detection and positioning control system for privacy area, through DAS/IBS systems included 2G 3G 4G 5G base station signal source hosts and fiber optical master/remote units, and positioning machines, mobile signal control is carried out in privacy area to achieve control functions: . interception of phone called number . black and white list selection . illegal phone detection . precise positioning . SMS broadcasting . IMSI catcher

. 2G：GSM900/1800MHz CDMA800MHz . 3G：WCDMA CDMA2000 TD-SCDMA . 4G：LTE-FDD: B1/B3/B5/B8 . 4G：LTE-TDD: B34/B38/B39/B40/B41 . 5G：N28/N41/N77/N78
