The MO1003 optical node has 3 high level outputs as well as 4 positions for optical modules. This allows several
configurations depending on the used CM module. First possibility is a standard node with 1 receiver and 1
transmitter module, second one is the redundant mode with 2 modules in each direction. Return path
segmentation is also achievable by using 2 or 3 transmitters with 1 receiver. By changing the CM module the
configuration of the device can be modified without high expenses. The MO1003 node is available with either for
HFC or for Fiber Deep network optimized circuitry

• Downstream frequency range up to 1006 MHz
• Upstream frequency range up to 204 MHz
• Optional connection to Monitoring System
• GaN output stage
• Optional CWDM return path
• Automatic optical gain control
• Automatic ingress management by the RSW module
• Redundancy option
