LR22 2001 - Fiber Nodes 

Description: 

The LR 2x series of fiber nodes are optical nodes for HFC, RFoG or RF Overlay applications. They can be operated in RFoG (burst-mode) and HFC (continuous wave) mode.

HFC Manager+

WISI’s HFC Manager is a comfortable tool to configure and manage your device configurations with your smartphone or tablet via the built-in Bluetooth chipset.

All known configuration parameters are available by the app to provide a more flexible way to rollout WISI HFC (Hybrid Fiber Coax) devices into your networks. Set your attenuation, ALC, slope values and many more easily with the intuitive user interface.

The app will store your device configurations which can then be managed locally or on a central appliance to apply the same configuration to other devices as well.
