The MDO1201 is a compact style node for FTTB networks with full electronic setup interface and remote
controlling option. The highest flexibility is ensured by the CWDM technology of the reverse path transmitter. The
node is available with local or remote powering and with single or dual fiber optical interface in special housing
improved for use in apartment houses' cabinets.
Benefits :-
• Downstream frequency range up to 1218 MHz
• Upstream frequency range up to 204 MHz
• Optional connection to Monitoring System
• Electronic configuration interface
• Single or dual fiber fiber optical interface
• Automatic optical gain control
• Ingress management
