The device has improved gain output stages to achieve high output level even in case of low OMI values. It contains a CM5 configuration module which enables the full segmentated operation mode for both forward and return path (2 transmitter and 2 receiver modules). In basic configuration the device contains 2 optical receiver modules and 2 transmitter modules and of course the configuration module. This node contains two WWDM filters beside the optical modules.

Benefits :-

 • Low noise optical receiver module
• Return path optical transmitter module
• Segmentation in forward and return path
• Pull-out internal casting tray electronics
• 2 high-leveled RF outputs (splittable to 2x2)
• Remote powered switching power supply
• Status monitoring option
• Built-in WWDM filters
