Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

The Cisco® 1.25 GHz Surge-Gap Flexible Solutions Taps (FST) are the latest products designed for the DOCSIS® 3.1 evolution of hybrid fiber-coaxial (HFC) networks. DOCSIS 3.1 technology allows cable operators to fully and efficiently use their broadband networks to provide the services that subscribers demand. As part of DOCSIS 3.1 support, the broadband operating frequency range has been increased to cover the entire 5 MHz to 1.218 GHz spectrum.

These products are also fully compatible with orthogonal frequency-division multiplexing (OFDM) signaling requirements. These new capabilities can contribute to higher customer revenue by allowing increased bandwidth across a network, so new and improved services can be provided. The taps (Figure 1) offer best-in-class performance along with added flexibility in system design. This flexibility is achieved using three types of optional plug-ins that are ideal for higher output, deep-fiber architectures.

Optional Plug-Ins

●   Reverse attenuators are available in 0, 3, 6, 9, and 12dB values. The attenuators increase the reverse path tap loss with only a minimal effect on forward tap loss. By selectively adding reverse attenuation to reduce reverse tap values, reverse path tap losses can be more similar across the various values of taps used in an HFC network. This approach allows the range of RF levels transmitted from closed-loop customer premises equipment (CPE) to be narrowed, which helps improve the reliability of upstream transmissions.

●   Forward equalizers used in Cisco 1.25 GHz Surge-Gap FST products are available in 2, 3, 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20 and 22dB values. The forward EQs increase the forward path tap loss in a standard cable-tilted fashion, with greater loss at lower frequencies than higher frequencies. The plug-in forward EQ allows optimization of tap output levels at tap locations near the end of the feeder line.

●   Forward inverse equalizers used in Cisco 1.25 GHz Surge-Gap FST products are available in 2, 3, 4, 6, 8, 9, 10, 12, 15, 18, and 21dB values. The inverse equalizers increase the forward path tap loss in a down-tilted fashion, with greater loss at higher frequencies than lower frequencies, and they have only a minimal effect on reverse tap loss. The plug-in forward inverse equalizer allows tap output levels to be optimized at tap locations with high-level forward RF signals and significant up-tilt (typically, they are tap locations closest to nodes and amplifiers).

Cisco 1.25 GHz Surge-Gap FST products all have IEEE-compliant 6-kV surge protection, providing significantly improved protection against voltage transients in lightning strike areas and locations with unreliable power networks. In addition, the new tap products offer the same AC/RF Bypass Switch capabilities of previous Cisco tap products, allowing the tap faceplate to be removed without interrupting service to downstream customers. The taps pass up to 12 amps of current, so operators can access power at locations within the HFC plant where additional power is needed.

Features

●   Expanded frequency range handles DOCSIS 3.1 requirements of 1.218 GHz and OFDM signaling

●   Optional plug-in reverse attenuators, forward equalizers, and forward inverse equalizers offer design flexibility

●   Choice of 2-, 4-, and 8-way versions

●   6-kV combination wave surge protection for both tap and through ports, with a rugged design that helps the products continue operating after surges that would typically damage products and interrupt service

●   12A through current rating

●   AC/RF bypass switch that avoids interruption to the rest of the network during faceplate removal

●   Backward-compatible faceplates that support economical faceplate upgrades into existing backhousings

●   Powder coating for superior environmental protection

●   Sealed and swaged extended F-ports that resist moisture

●   Nickel-plated brass F-ports that provide a corrosion-resistant drop interface

●   Component covers for additional protection of faceplate circuitry during maintenance

●   Versatile housing design that permits overhead, pedestal, or multiple dwelling unit (MDU) mounting schemes

Note:   
The specifications above show typical tap measurements with plug-ins installed. A few deviations to these general specifications are noted in the following list:

Note 1: For the 2-way 8-dB and 11dB taps, the tap-tap isolation of from 5 to 750 MHz is 17 dB, and the tap-tap isolation from 751 to 1250 MHz is 14 dB.

Note 2: For 2-way 4 dB with forward equalizer, the input return loss is 16dB.

                For 2-way 8 dB and 11 dB, the input return loss is 14 dB and 17 dB, respectively.

                For 4-way 8 dB, the input return loss is 13 dB.

Note 3: For 2-way 8 dB and 11 dB, the tap port return loss is 12 dB and 14 dB, respectively.

Note 4: Tested per ANSI/SCTE 48-2 2003.

All return loss and isolation specifications noted in the list are typical performance specs. Worst-case specs would degrade no more than 1 dB for any given spec.
