Cisco 1.25 GHz Surge-Gap Reverse Window Taps Data Sheet
Available Languages
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.
Reverse window taps provide benefits in the HFC plant at tap locations with high level forward RF signals and significant up-tilt (typically the tap locations closest to nodes and amplifiers). The 1.25 GHz reverse window taps are offered in several forward and reverse tap values (Figure 1).
In the forward path, the tap loss in the reverse window tap is deliberately down-tilted, with greater loss at higher frequencies than at lower frequencies. This allows more frequent use of high-value taps, which increases system design efficiency, and it improves the ability to optimize tap port levels.
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.
Features
● Six forward path cable slope values and two reverse path values available in various combinations
● Available in 2-, and 4-way standard Surge-Gap Tap Housings
● Also available in 2-, 4-, and 8-way full profile housings
● AC/RF bypass switch that provides interruption-free service to downstream subscribers during faceplate removal
● 12A through current rating
● AC blocking capacitors on each port to minimize RF signal distortions
● Backwards-compatible housing that supports economical faceplate upgrades
● Increased surge tolerance with rugged design that lets new products continue to operate after surges that would typically damage ordinary products and interrupt service
● Improved return loss to lessen reflected signals for a “cleaner” signal
● AL360T housing with powder coating for superior environmental protection
● Sealed and swaged extended F-ports for greatest resistance to moisture ingress
● Nickel-plated brass F-ports to help ensure a corrosion-resistant drop interface
● Component covers for additional protection of faceplate circuitry during maintenance
● Versatile housing design that permits aerial, pedestal, or multiple dwelling unit (MDU) mounting schemes
