Fiber Modem with Dual SFP Modules
The FlexDSL Fiber Modem with Dual SFP options provides the Fallback to the SHDSL interface in case of a failure of a fiber link.
Upon the restoring the fiber link, the FlexDSL Fiber Modem will automatically switch the traffic back.
Dual SFP and Four-SHDSL interfaces allow different topologies such as line, ring, star and add-drop.
Fiber Modem with Single SFP Modules
Like the Dual-SFP version of the FlexDSL Fiber Modem, the Single-SFP modem provides the Fallback to the SHDSL interface in case of a failure of a fiber link.
This model can be used in the Point-to-Point applications, where add-drop or redundancy are not required.
