Abstract: With the rapid development of the optical communication industry, the implementation of national policies, the increase of broadband access fiber-to-the-home investment, and the continuously increased requirements for the important components in the construction and deployment of FTTH system solutions of the communication industry, fiber connection has become an important link in FTTH. The fast connector has become the main method of optical connection, and the emergence of the fast connector solves the problem that the optical fiber can only be spliced. This article mainly introduces the basic characteristics and technical parameters of high-performance fully compatible FMC fast connectors which is an important device in the construction and deployment of the current FTTH system solution. By implementing the basic characteristic of “high performance” and “fully compatible”, it can meet all the terminal connection demand under various FTTH constructions deployment. And at the same time, this article briefly explains the convenience of construction and practical application of the FMC fast connectors. Through the optimization and improvement of various performances, the connector product has become an important technology for future FTTH network construction. It is suitable for terminal connection in various FTTH construction deployment environments, reducing on-site construction costs, improving assembly efficiency, providing convenience and services, and meeting the needs of customer terminal connection with different usage habits.

Abstract: Linear orthogonal binary sequences, special M-Sequences, are used widely in the systems communication channels as in the forward links for mixing the information on connection and as in the backward links of these channels to sift this information which transmitted and the receivers get the information in a correct form In current research trying study the construction of the linear equivalent of a product sequence on two, three, and four degrees over a linear sequences from the field Fp, where p is larger than two, and answering on the request, how is the maximum length of the linear equivalent of a product sequence (on a linear sequence {an} over the field Fp), is it less than rNh as the binary sequences?, or can reach it ?, or the length is exceed this value rNh? And is the product sequences are orthogonal? And we show that in some cases, the maximum length rNh for the binary sequences is not correct for the linear sequences in the finite field Fp for p larger than two and the result product sequences are not orthogonal, also trying study the product sequence on two different LFSRs, and how can use one shift feedback shift register LFSR as a monitor register of other p registers. In the current time, I think, there is no coders or decoders using the sequences over finite fields Fp where p is larger than 2 and from this idea this article showing very need for using in the future.
