M-DOTS Digital Multi-Band Optical Transport System

Helios® Digital Multi-Band Optical Transport System (M-DOTS) is designed to integrate multi-band systems and extend the cellular coverage into large Public Venues, such as Hospitals, Hotels, Shopping

Helios® Digital Multi-Band Optical Transport System (M-DOTS) is designed to integrate multi-band systems and extend the cellular coverage into large Public Venues, such as Hospitals, Hotels, Shopping Malls, Office Buildings, long Tunnels sections and large area outdoor coverage.

The M-DOTS consists of a Master Unit (MU), and Remote Units (RU’s). MU consist Optical Master Unit (OMU) and Extension Master Unit (EMU). MU supports up to 48 digital optical fiber port, and each port can support up to 8 remote unit’s in cascading connection. Loop redundancy function can be supported.

M-DOTS is a cost-effective and intelligent solution that can be used in cases when optical master unit and remote unit are not located close to each other. In the downlink, OMU pick up the Multi-Band Base Station signal and covert it to digital signal, and convert digital signal to optical signal, then transport by optical fiber. In RU, digital signal will be changed back to RF signal and then amplified by the high power and high linearity amplifier (HPA), and output to the coverage area. It operating supporting all major cellular frequency bands including 700MHz, 800MHz, 1800MHz, 1900MHz, 2100MHz or 2600MHz and supports all major wireless technologies include GSM, EDGE, DCS, CDMA, UMTS, LTE FDD, PCS and AWS.
