Abstract
The low-cost in-home distribution of full-standard digital TV jointly with high-bitrate data using 50 m long 1 mm core diameter graded-index plastic optical fiber (GI-POF) is proposed and experimentally demonstrated. Discrete multitone (DMT) modulation is demonstrated to provide an adaptive bitrate which can spectrally coexist with digital video broadcasting-terrestrial (DVB-T) signals in 470-862 MHz. A 3 Gb/s DMT signal and two DVB-T channels are generated, transmitted and received exhibiting excellent performance.
Highlights
Nowadays, optical fiber based in-home network solutions can outperform copper- and wireless- based solutions regarding performance and costs
Quality of experience (QoE) observations on the video quality showed that video images received after the plastic optical fiber (POF) transmission can hardly be distinguished from the source
We propose the baseband stream provided by the access network to be implemented with Discrete multitone (DMT) modulation, which has been widely implemented in digital subscriber line commercial chipsets
Summary
Optical fiber based in-home network solutions can outperform copper- and wireless- based solutions regarding performance and costs. Real-time high-definition (HD) video signals have been transmitted with ultra-wideband (UWB) format over large-core GI-POF [6]. To explore full scenario for in-home broadband application with a low-cost and adaptive solution, a converged transmission of high-capacity baseband stream employing a discrete multitone (DMT) technique and real-time full-standard digital video broadcasting-terrestrial (DVB-T) signals [7] over 50 m long 1 mm core diameter PMMA GI-POF is proposed and experimentally demonstrated. Quality of experience (QoE) observations on the video quality showed that video images received after the POF transmission can hardly be distinguished from the source This approach enables the effective replacement of the legacy coaxial cabling typically providing TV ports in the home
