SQON - S Reverse Segmentable Node is a economic platform with high performance, 4 passive output ports, and compact size optoelectronic nodes with bandwidth up to 1000MHz.
It is capable of providing 50dBmV output level with 4 ports at 1000MHz. Modular design enables the Multiple Service Operators to choose the minimal configuration as the present requirement and expand when need in the future. The SQON - S is able to accommodate 2 forward receiver modules and 2 return path transmitters, with redundancy functionality. The SQON - S can be upgraded to different frequency by change some plug-in modules.
The goal for the product is to provide system designer an economical and robust node in CATV optical network.
