Wireless Interconnect is at the heart of most modern technology, and the need for strong, secure wireless performance is only growing with IoT and the popularity of smart devices. Module systems must offer reliable performance and support the latest protocols to provide easy internet access for end consumers. These modules can offer a variety of inputs, including SD and USB capability, and new designs are expected to improve efficiency and system sensitivity in small sizes.
Our broad product portfolio includes 25G SFP28 and 50G QSFP28 to support 5G development. Together they compose a comprehensive suite of solutions capable of delivering highly efficient power in small package sizes. Our innovative, cost-effective solutions help simplify design and provide high levels of integration so wireless access is simple and secure, and customers can stay connected.
Primus IT's innovative, efficient optical transceivers offerings help enable the best wireless Interconnect.
The GBIC module is divided into two categories: one is the ordinary cascade GBIC module, which realizes the common connection with other switches; the other is the stack special GBIC module, which realizes the redundant connection with other switches.
GBIC is basically replaced by SFP for the following reasons:
SFP (Small Form-factor Pluggables) can be simply understood as an upgraded version of GBIC. SFP module (half the size of the GBIC module, you can configure more than twice the number of ports on the same panel. Because the function of SFP module is basically the same as that of GBIC, it is also called miniaturized GBIC (Mini-GBIC) by some switch manufacturers.
The SFP module further reduces the size and power consumption by placing CDR and electric dispersion compensation on the outside of the module. Used in optical communication applications in telecommunications and data communications. SFP connects the motherboard and fiber or UTP cables of network devices such as switches, routers, and so on. SFP is an industrial specification supported by some optical fiber device providers.
SFP supports SONET, Gigabit Ethernet, fibre Channel (Fiber Channel), and other communication standards. This standard extends to SFP+, to support 10.0 Gbit/s transmission rates, including 8 gigabit fibre Channel and 10GbE. The optical fiber and copper core version of the SFP+ module is introduced. Compared with the Xenpak, X2 or XFP version of the module, the SFP+ module leaves part of the circuit implemented on the motherboard rather than in the module.
Sfp interconnect cable is the main type of high-speed IO interface interconnection system that has long been used to connect servers, storage, switches, video and communication systems. The main market segment implementations include cloud data centers, enterprise data centers, HPC (High performance Computing) labs, camera surveillance systems, and so on.
FP interconnection system is developed from HSSDC (High Speed Serial data Connector). HSSDC-1 and HSSDC-2 break with the traditional use of two-piece metal connector contact systems because plug connectors use PCB with gold-plated pads to match the metal contacts of edge socket connectors. Compared with the previous very large, heavy and wide parallel IO interface connectors and cables, modern sfp interconnect cable is more convenient and efficient. SFP is also used for 2.5, 5, and 8 Gbps data rate applications, including InfiniBand standard single-channel links.
The so-called wireless network refers to a network that can realize the interconnection of various communication devices without wiring.
Wireless network technology covers a wide range, including global voice and data networks that allow users to establish long-distance wireless connections, as well as infrared and radio frequency technologies optimized for short-distance wireless connections.
1) Strong mobility, able to break through the limitations of time and space
2) Relatively strong network expansion performance
3) Relatively strong network expansion performance

In order to effectively improve the security of the wireless network, it is necessary to use corresponding data encryption methods and network login authentication, so as to do a good job of security defence. In addition, to ensure wireless network security, it is also necessary to do a good job in the supervision and maintenance of wireless equipment and to monitor the operating status of wireless network equipment in real-time. When abnormalities occur, take corresponding measures immediately.
The wireless network transmits the network signal by transmitting radio waves, as long as it is within the transmitting range, use the corresponding receiving device to realize the connection to the corresponding network.
