Optical Wavelength Division Multiplexing (WDM) networks based on fixed grid technology have exposed some questions, including wasting of bandwidth resources in multi-domain heterogeneous networks. Flexible grid technologies can provide end-to-end optical path according to the client flexibly and effectively. However, it is unpractical to deploy a one-time green-field flexible grid technologies subjected...
The Resonant Fiber Optical Gyroscope (RFOG) is an important component in the inertial navigation systems due to the small size, low cost and low power. A new method of using two semiconductor lasers locked to the clockwise resonance and the counter-clockwise resonance of a resonant is proposed. This paper analyzes the principle of beat note and do a simulation program. At last we can obtain the difference...
We realize a stable single source infinite impulse response microwave photonic filter with GHz level free spectral range based on a coherence managed multi-longitudinal-mode erbium doped fiber laser by controlling the filter bandwidth and cavity length.
We propose a converged fiber-wireless access network based on radio-over-fiber technologies as future mobile backhaul incorporating base station cooperation schemes (CoMP). Both analog and digitized RoF technologies are discussed as possible solutions, in terms of base station configuration, system performance and energy efficiency. The implementation approach and the capacity gain of CoMP are analyzed...
A 10-Gb/s reconfigurable all-optical VPN scheme in WDM-PONs based on mutually injection-locked Fabry-Pérot laser diodes is proposed and experimentally demonstrated. After 25-km fiber transmission, the power penalty at BER of 10−9 is 1.4 dB.
MEMS accelerometer sensors have been developed in decade years at various techniques such as piezoelectric, piezo-resistive, and micro capacitive etc. But the optical technology will bring the new activity and potential. In this paper, a accelerometer sensor based on the light transmission measurement and micro electromechanical system (MEMS) technology is proposed and simulated. Light power is coupled...
With the popularizing of digital TV, Cable TV(CATV) network develops rapidly in the recent years. More large scale resource involved in the CATV network makes demands of the more effective management system. This paper analyses the characteristics of CATV network resources, offers a hierarchical model and gives the architecture, development principles, and implementation of a comprehensive CATV Network...
