The Cisco Surge-Gap Flexible Solutions taps (FST) are the 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 spectrum. These products are also fully compatible with orthogonal frequency-division multiplexing (OFDM) signaling requirements. These capabilities can contribute to higher customer revenue by allowing increased bandwidth across a network, so improved services can be provided. The taps offer excellent performance along with added flexibility in system design.
