Optical Node (1 Receiver Module, Gan Hybrid, 3 Active Outputs)

The Optical Node (1 Receiver Module, Gan Hybrid, 3 Active Outputs) (Part number: MO1003DH-XX-SA) from Comtech is a Optical Nodes. Optical node is a device that has a broadband optical receiver which translates optical signal coming from the headend or hub to an electrical signal for homes. Also, fiber optic node contains a reverse path transmitter that sends communication from homes back to the headend.

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.
