23dBm 900-1800-2100MHz MIMO Tri-Band Fiber Optic Remote Unit
EMTS Telecom Services Ltd. Fiber Optic Repeater System is a highly reliable and proven solution for extending and improving the coverage of 900/1800/2100 MHz telecommunication networks. The system is composed of two main modules: the Master Unit (MU) and the Slave Fiber Remote Unit (RU). A single Remote Unit supports MIMO in 1800 ,2100 MHz bands.
The Master Unit can be directly connected to the BTS or integrated with an RF repeater that receives the BTS signal. The Remote Unit delivers enhanced signal coverage within the designated service area.
The EMTS Fiber Optic Repeater System amplifies signals in both uplink and downlink directions over a continuous, factory-tuned bandwidth. Its robust design, easy deployment, and straightforward field maintenance significantly reduce operational costs and ensure high reliability with an extended mean time between failures (MTBF).
This cost-effective and scalable solution is ideal for extending reliable mobile coverage in challenging environments such as subways, tunnels, large indoor facilities, and complex outdoor distribution scenarios.
