In the information age, data communication and storage are happening at any time. Around the world, people use computers and entertainment cell phones to upload and download data all the time. These data contain a lot of information, most of which are gathered in the data center, exchanged through the switch, or uploaded to the server for backup storage. In order to prevent personal, business and government information circulating on the network and stored on the server from being leaked or even stolen, server and network security have become increasingly important.

In order to meet the society's need for information security, many companies with the purpose of server and network security were born. They provide a variety of hardware and software to ensure the security of user information. Among them, the most important hardware devices are servers and firewalls, while high-end servers and firewalls are equipped with pluggable optical transceiver module interfaces for data transmission.

Due to the need to store a large amount of information, data centers are usually equipped with a large number of servers and firewall equipment, so they have specific requirements for optical transceiver modules dedicated to this aspect. For example, data communication in data centers generally uses Ethernet technology, so optical transceiver modules must first support Ethernet standards (currently mainly 10GE, 25GE, 40GE, and 100GE); In addition, most storage area networks in data centers use fiber channel as the information storage, Which requires that its servers and corresponding optical modules support the Fibre Channel standards (currently mainly 8GFC, 16GFC and 32GFC, and 4x32GFC). In addition, due to the large number of devices, the number of optical transceiver modules corresponding to the demand is also large. In order to reduce energy consumption and better heat dissipation, the power consumption of the optical transceiver modules needs to be as low as possible.

In response to the requirements of optical transceiver modules for servers and network security applications in data centers, Gigalight can provide a comprehensive solution that supports 1G to 100G Ethernet and 2G to 128G Fibre Channel.

In addition, in order to strengthen the control of information content security, enterprises or governments usually use deep packet inspection (DPI) technology to monitor the transmission quality of communication data of various business systems in large data flows, and in the category of massive network communication data. There is a small amount of malicious traffic detection to avoid the security threats to the root permissions of the host and network devices by malicious communication and the theft of communication content. By capturing the original data packets of network communication, DPI technology can use its three main types of detection methods: detection based on "eigenvalues" of application data, identification detection based on application layer protocols, and data detection based on behavior patterns. According to different detection methods, the abnormal data that the communication data packet may contain are unpacked one by one, and the subtle data changes in the macro data stream are deeply dug out.

The DPI technology significantly strengthens the security and management performance of the current network, and plays an increasingly important role in the centralized network policy control and accelerated automation process under the current technology trend of combining software-defined networking (SDN). With the rapid increase of data traffic in recent years, the improvement of network center security requirements of data centers and large Internet companies, and the enhancement of personalized awareness of user services, the DPI industry has developed rapidly. The optical modules used for DPI devices have also evolved from 10G/40G to 100G rates in the past, and have derived new requirements for power consumption and non-relay transmission.

Aiming at the feature that the traffic collection device in DPI only needs to collect optical signals, Gigalight has developed a series of DPI optical modules for network security monitoring applications in optical transmission networks, which can even meet the information security requirements in 5G fronthaul networks.
