Description 

Helios® Multi-Band Digital Optical Transport System (M-DOTS™) is the most flexible, scalable and complete solution for addressing coverage and capacity needs for cellular and public safety wireless network. The M-DOTS™ improves wireless network coverage and capacity by extending services from existing cell sites, to hard-to-reach areas by digital CPRI distributing coverage from a centralized radio suite.
Utilizing a centralized digital CPRI distributed architecture, Helios® M-DOTS™ is a two-tier architecture consisting of the Optical Master Units (OMUs) and Optical Remote Units (ORUs). 

The M-DOTS™ - ORU utilize a modular design, which support up to six bands. Each ORU allows for easy field access and future upgrades to add RF bands or technologies by simple HotSwap.

Typical mounting options for the ORU include pole-mount and wall-mount. And the enclosure of the M-DOTS™ - ORU is fully sealed IP-67 rated with unique 250mm depth compact design, which minimizes maintenance and is ideal for harsh environments. The ORU owns a hot-swappable external Fan Tray with four high-performance temperature-controlled fans with IP65-rated waterproof design, it is ideal & flexible field replaceable units (FRUs) for increasing ventilation for ORU, better airflow keeps device cool and helps boost system performance and avoids costly equipment failures.

On the forward path, the ORU receives the digitized spectrum from the OMU and converts the spectrum back into RF to be distributed via an externally mounted antenna system. On the reverse path, the ORU digitizes the designated RF spectrum and digitally transport it over single-mode fiber to the OMU
