Cisco® 1.25 GHz Surge-Gap Reverse Window Taps are the latest products designed for the DOCSIS® 3.1 evolution of hybrid fiber-coaxial (HFC) networks. They offer all the benefits of our standard surge-gap taps and allow increased efficiency in system design by reducing reverse path tap losses and tilted forward path tap losses.

In the reverse path, the reverse window taps have lower tap losses than traditional high-value taps. By using Reverse Window taps, the total range of reverse path tap losses in the HFC plant can be narrowed. This improvement allows the range of RF levels transmitted from closed loop customer premises equipment (CPEs) to also be narrowed as well, which can improve the reliability of upstream transmissions. All surge-gap tap products have IEEE-compliant 6kV surge protection. As a result, they offer greatly improved protection against voltage transients in lightning-strike areas and locations with unreliable power networks.

The 1.25 GHz reverse window taps continue to offer the make before break capabilities of previous Cisco tap products, which allow a tap faceplate to be removed without interrupting service to downstream customers.
