  QSFP is the abbreviation of "Quad Small Form-factor Pluggable", which is an optical module specification that can be used in high-speed network equipment. Its scope of application mainly includes the following aspects: 1. Data center network:  QSFP optical modules  can be used in high-speed data center networks, such as for the connection of switches, routers, servers and storage devices. 2. Optical fiber communication: QSFP optical modules can be used to transmit digital signals, audio and video signals, etc. in long-distance optical fiber transmission. 3. Cloud computing: With the development of cloud computing technology, QSFP optical transceivers are widely used in cloud computing systems, such as data center networks and cloud storage. 4. High-speed communication: QSFP optical modules support transmission rates up to 40Gbps or 100Gbps, and can be used in high-speed communication networks, such as financial transactions, high-frequency transactions and other fields....

  Because the maximum transmission distance of the network cable (twisted pair) we often use has great limitations, the maximum transmission distance of the general twisted pair is 100 meters. Therefore, when we are laying out larger networks, we have to use relay equipment. Of course, other types of lines are used for transmission.   Optical transceiver   is a good choice. The transmission distance of optical fiber is very long. Generally speaking, the transmission distance of single-mode fiber is more than 10 kilometers, and the transmission distance of multi-mode fiber can reach up to 2 kilometers. When using optical fibers, we often use optical transceivers: If you want to know how to use optical transceivers, you must first know what the  optical transceivers  do. Simply put, the role of the  optical transceiver  is the mutual conversion between optical signals and electrical signals. The optical signal is input from the optical port, and the elec...

  The 25G Ethernet solution is a solution standardized and developed by the IEEE 802.3 working group P802.3by. This solution is mainly used in the data center environment. The 25G Ethernet Alliance was established in July 2014 to support the deployment of single-channel 25GB/s solutions and dual-channel 50GB/s Ethernet solutions. The 25GB Ethernet Alliance was completed in September 2015. In November 2015, the 802.3 working group was established to develop a single-channel 25 GB/s Ethernet solution. On June 30, the IEEE 802.3by standard was approved by the IEEE-SA Standards Committee. The FiberWDM 802.3by standard defines the following technologies: Single channel 25 GB/s 25GBASE-KR PHY for printed circuit backplanes. PHY is a chip, an abbreviation for the physical layer of the OSI model； Single channel 25 GB/s 25GBASE-CR-S PHY for 3 m twinaxial cable (in-rack) Single channel 25 GB/s 25GBASE-CR-L PHY for 5 m twinaxial cable (between racks)  ； Single channel 25 GB/s for 100 m O...

  The   optical fiber transceiver   is an Ethernet transmission media conversion unit that exchanges short-distance twisted-pair electrical signals and long-distance optical signals. It is also called a photoelectric converter in many places. The product is generally used in the actual network environment where the Ethernet cable cannot cover and the optical fiber must be used to extend the transmission distance, and is usually positioned in the access layer application of the broadband metropolitan area network; at the same time, it helps to connect the last mile line of the optical fiber to the metropolitan area. The Internet and the outer network also played a huge role. Since the maximum transmission distance of the network cable (twisted pair) we often use has great limitations, the maximum transmission distance of the general twisted pair is 100 meters. Therefore, when we are laying out larger networks, we have to use relay equipment. Of course, other types of lines...
