1. Overview
A Multi Band (800㎒/1.8㎓/2.1㎓) optical repeater that used in large cities that has large telephone traffic and small town that the signal is weak, to expands the coverage of the base station and solve the issues with the area with weak signals.
2. Characteristics
① Application of digital signal processing and transmission system based on minimizing transmission losses allow long distance transmission
② The advantages of digital signal utilizing practical expandability (Multi-drop, Cascade)
③ The external battery installed prevent service interruption due to the power outage
④ To protect the equipment when the antenna is removed, an isolator is installed on active output.
⑤ When MIMO is made up, support of maximum 5 cascade is available and optic module that can changeover is used when there is a faulty.
