Optical Fiber Transmission Applications Are Promising In Security Monitoring

As a variety of image status and data monitoring have more and more requirements, the transmission distance of video signal can not meet the demand anymore. Therefore, the gradual development of optical integrated video and control signals (WDM or DWDM technology) can transmit longer distance. In addition to the combination of images and control, the […]

A PON Based on Code-division Multiplexing Access

Because of the Internet and broadband networks were introduced, the emerging applications – such as teleconferencing, video on demand, and high quality audio transmission has strict high flux optical access network quality of service (QoS) capabilities. However, the infrastructure of current access networks suffers from limited bandwidth, high network-management costs, poor flexibility, and low security, […]
