The MDO800E optical node is developed for customers, who provide only video services by the conventional and
unidirectional HFC network, but want to achieve the advantages of a monitoring system. Regarding to this the RF
section is optimized for the TV band, contains an optical AGC, while the monitoring circuit delivers information
about the total output RF power change, the RF alignment (EQ, AT) and other working parameters (temperature,
DC voltage etc.) via an independent Ethernet connection. 

Benefits :- 

• Electronic configuration interface
• Automatic optical gain control
• Cost-effective solution
• Connection to Monitoring System via Ethernet
