The 28GHz 5G Wireless Optical DAS is a repeater system that can improve poor mmW 28GHz band indoor/outdoor wireless environments. This repeater is installed and operated between the base station and the terminal(phone), and can improve operator's network and facility infrastructure efficiently to provide 5G(2X2 MIMO) service.

- DU(Donor Unit), MDU(MHU to DU Interface Unit), MHU(Main Hub Unit), DRU(Distributed Remote Unit), mRU(mmWave Remote Unit)
- DU: Internal Dual Polarization Antenna (±45º) and 2X2 MIMO support
- MHU (including MDU): 5G base station 28GHz signal transmission/reception
5G signal transmission/reception to lower equipment (Optic cable 1 core)
- DRU: Sends signal to 4 mRUs(each coaxial 2core) and supplies DC power(+37V) to mRU
- mRU: Internal Dual Polarization Antenna (±45º) and 2X2 MIMO support
Provides 28GH 5G MIMO service
