We propose a remote coding scheme by using the cascaded encoder for passive optical network monitoring. The cascaded encoder is composed of $1\times 2$ power splitter/combiners and fiber Bragg gratings, located at the remote node that can simultaneously realize optical splitting and coding. We also present the cascaded encoder design, simple network recognition algorithm, and the false alarm rate...
An OTDR similarity trace analyses based effective method for fault location in point-to-multipoint PON is presented and experimentally demonstrated. Fault caused by similar length between the branches can be discriminated.
Remote coding for PON monitoring system using waveguide Bragg grating based PLC splitter chip is proposed. It can realize optical coding and power splitting simultaneously at the remote node and then release the user cost. The optimum designs are given with high capacity of users at minimum grating number.
Changing farmers' attitude and raising motive force are the inner demand for extending healthy culture model in the pig industry. The paper discussed influence factors that impede farmers involving the healthy pig industry, designed a dynamic mechanism model based on the coefficient of sharing benefits and risk between enterprise and farmers using the theory of principal-agent. The special investment...
The traditional agricultural Chain in China faces contradictions and conflicts such as huge risk, high cost, low coordination and bad agility etc. Under the guidance of theories of service profit chain, value chain, supplying chain management and TRIZ, etc., the thesis digs deeply and analyzes the creative practice and effects from cultivation service value chain of Guangdong Wen's food group Co....
