“…Later, a Content Distribution Network (CDN) was created to provide advanced multimedia services over a packet-switched network based on the Internet Protocol (IP), namely IPTV system. The IPTV content is delivered to Set-Top Boxes (STBs) through a dedicated and managed network using multicast and initial unicast burst during channel change [14].…”

“…In the last few years, Over the Top entertainment (OTT) services have been launched and streamed directly to viewers using modern interactive platforms based on wireless technology. OTT services are privately owned media services that offer subscribers content streaming anywhere and at any time through an open internet and unmanaged network utilizing unicast and simulated multicast (User Datagram Protocol or UDP/Transmission Control Protocol or TCP) routing topology [14]. The evolution of OTT posed new challenges to cable operators that prompted them to develop IPTV service delivery architecture to provide interactive TV services, popular Video on Demand (VoD), and PPV services like YouTube, Netflix, Hulu, Sky Go, Amazon Prime, and others.…”

“…The broadband service is supported by a Cable Modem Termination System (CMTS) or a Converged Cable Access Platform (CCAP) at the headend and a cable modem at the subscriber location. A Passive Optical Network (PON) system at the headend and an Optical Networking Unit (ONU) at the subscriber location are additional options for supporting this service [14].…”

Recently, the issue of monitoring and repairing leakage from cable television networks have re-emerged, particularly after the International Telecommunication Union released a part of the ultra-high frequency spectrum to mobile broadband services. The newly allocated spectrum, known as the digital dividend bands, was traditionally used throughout Europe for digital TV broadcasting. The emerging problem is the mutual interference between the new frequency spectrum utilized by the Mobile/Fixed Communication Networks and the band used by cable TV providers to offer their services. This article is a brief overview and a starting point for extensive research in this area. We started with a simple description of the cable television system and mobile/fixed communication networks focusing on the aspects associated with ingress and egress interference issues. We also discussed the approaches for detecting and measuring mutual interference and reviewed the relevant literature. This article is concluded with some proposed measures for reducing or mitigating mutual interference.

DOCSIS® 3.1 systems were designed to achieve high capacities with predictable Quality of Service (QoS) promising 2 Gbps on the upstream and 10 Gbps on the downstream. This paper describes L2VPN business services over DOCSIS® 3.1, extension of MPLS to customer premise, virtualization of Customer Premises Equipment (CPE) and interaction of the L2VPN application with SDN controller to support business services.

“…Video-intensive services, such as virtual reality and immersive applications are driving the growth of data traffic at user premises in an explosive way, making access networks become a bottleneck of user quality of experience. Various optical and wireless access technologies have been investigated, including passive optical networks (PON) [1][2][3], cloud-radio access networks (C-RAN) [4][5][6][7], and hybrid fiber coax (HFC) networks [8,9]. In the United States, there are more than 50 million subscribers using cable services for broadband access, which is 40% more than digital subscriber line (DSL) and fiber-to-the-home (FTTH) users [10].…”

We first demonstrate delta-sigma digitization and coherent transmission of data over cable system interface specification (DOCSIS) 3.1 signals in a hybrid fiber coax (HFC) network. Twenty 192-MHz DOCSIS 3.1 channels with modulation up to 16384QAM are digitized by a low-pass cascade resonator feedback (CRFB) delta-sigma analog-to-digital converter (ADC) and transmitted over 80 km fiber using coherent single-λ 128-Gb/s dual-polarization (DP)-QPSK and 256-Gb/s DP-16QAM optical links. Both one-bit and two-bit delta-sigma digitization are implemented and supported by the QPSK and 16QAM coherent transmission systems, respectively. To facilitate its practical application in access networks, the coherent system is built using a low-cost narrowband optical modulator and RF amplifiers. Modulation error ratio (MER) larger than 50 dB is successfully demonstrated for all 20 DOCSIS 3.1 channels, and high order modulation up to 16384QAM is delivered over fiber for the first time in HFC networks. The raw DOCSIS data capacity is 54 Gb/s with net user information ~45 Gb/s. Moreover, the bit error ratio (BER) tolerance is evaluated by measuring the MER performance as BER increases. Negligible MER degradation is observed for BER up to 1.5 × 10 −6 and 1.7 × 10 −4 , for one-bit and two-bit digitization, respectively.
