چکیده
During the past decade, cable television (CATV) systems have evolved from one-way broadcast of analog video transmission to two-way hybrid fiber/coaxial (HFC) networks delivering both analog and broadband services. The broadband services include high speed internet access, cable telephony, video-on-demand, and digital video. In this talk, we describe HFC transmission systems including the infrastructure, transmission formats, enabling technologies, system performance and impairments. The performance results of some typical HFC/CATV transmission systems are discussed along with the impact of fiber nonlinear effects. The fiber nonlinear effects include stimulated Brillouin scattering, self phase modulation, stimulated Raman scattering, and cross phase modulation. The methods to minimize the effects of fiber nonlinear impairments are also presented.

Many cable operators have begun the process of upgrading their cable systems in anticipation of delivering a wide range of interactive digital services to the home. These newer hybrid fiber-coaxial (HFC) networks can take advantage of unused bandwidth in broadcast cable television (CATV) and allow for an inexpensive and simple way for home users to have access to many broadband digital applicat...
متن کاملAdaptive scheduling in DOCSIS-based CATV networks
This paper studies the effect of the DOCSIS MAC layer on the performance of two-way TCP transfers in Hybrid Fiber Coax (HFC) networks. We propose a new adaptive scheduling scheme called Long Packet Deferment (LPD) at the headend to improve TCP performance in DOCSIS-based HFC networks. LPD reduces the frequency of transmission of long packets and, if such long packets are transmitted, they are s...
