With the development of the Internet network, various new business application models have appeared, and the demand for the construction of Internet site data centers has also continued to increase, which promotes the continuous development of data centers from architecture to technology. As a representative type of business application model, search business is not only a necessary functional component in large professional search websites, but also in any application that provides massive information, and it also poses challenges to the traditional network architecture of data centers. .

Three-play integration mainly refers to the integration of services, using a new network structure to meet the needs of three services including video, data and voice. The three-network integration of radio and television operators can be realized based on the PON system. The principle is to integrate the PON system and the CATV system through WDM (wavelength division multiplexing) technology, and transmit 1550nm, 1490nm and 1310nm signals through one optical fiber. Among them, the downlink signal is divided into two channels, one is the PON data signal, the optical wavelength is 1490nm; the other is the CATV broadcast signal, the optical wavelength is 1550nm. The upstream signal is a PON data upstream signal with a wavelength of 1310 nm.

FTTH (Fiber to the Home) can provide higher bandwidth for users to meet different demands of voice, video, and data with fiber as the transmission medium, which will gradually replace copper accessing technology. PON (Passive Optical Network) is recognized as the best FTTH network accessing technology in the industry with no active power devices and passive devices between the local and user sides. Due to its advantages such as high bandwidth, good network stabilization, the convenience of management and maintenance, and low cost, the FTTH solutions become the current preferred network accessing solution with consistent approbation from big operators worldwide.Focuscom specializes in PON technology, and product development has a wide range of product series and can provide users with end-to-end product solutions.

Service convergence is a basic requirement for the development of network integration. Focuscom provides system solutions for enterprise network solution architecture at the three levels of basic platform, service management and value-added services, and builds an end-to-end manageable, full-line speed and full-service enterprise network platform. Through clustering, stacking, QoS, controllable multicast, and security technologies, it provides excellent manageability features to fully meet the comprehensive transmission of voice, data, and video services. It provides a full range of Ethernet switches to tailor network solutions for small and medium-sized enterprises.

In recent years, with the rapid development of access markets worldwide and the rapid development of full-service operations, the existing PON The technical standards are in terms of bandwidth requirement, service support capability, and performance improvement of A-Node equipment and supporting equipment New upgrade requirements are faced.
