LUMO is a high-density 1 RU frame with 36 SFP-based fiber converters, ideal for large distribution of high bandwidth 3G signals. LUMO's 1 RU size minimizes rack space and often complex cabling concerns have been greatly reduced by including fiber connectivity on one side of the unit and coax electrical on the other. Reliability and serviceability is further secured through the use of hot swappable cards and a redundant PSU, as well as remote system health monitoring and alarming for all key components, including optical signal strength.
