  The rapid development of science and technology makes people's lives change with each passing day. With the continuous advancement of applications such as 5G, big data, blockchain, cloud computing, Internet of Things, and artificial intelligence, data flow has increased unprecedentedly, and data center interconnection has become a research hotspot in optical communications.   The current high-speed optical transceiver application scenarios are mainly Internet data center networks, metropolitan area network optical transmission networks, and telecommunication networks represented by 5G bearer networks.   Ⅰ . The application of fiber optical transceivers   in data centers   The current data center is no longer just one or a few computer rooms, but a group of data center clusters. In order to realize the normal operation of various Internet services and application markets, coordinated operation between data centers is required. The real-time mass exchange of information between dat

  In recent years, with the rapid development of data centers and increasing data transmission among manufacturers and users, the rates of optical transceivers have evolved from 25G and 40G to the current 100G, 200G, etc. Correspondingly, AOC has been developed to a new level.   Active optical cable (AOC) can be said to be a new type of transmission medium for high-density and high-bandwidth applications in the era of big data. Compared with traditional cables, active optical cables have high transmission rates, long transmission distances, low energy consumption and convenient way to use. Active optical cables benefit communication equipment with the huge advantages of optical transmission, and it is an ideal transmission cable for data centers, consumer electronics and other fields.   However, why can direct attach cables   still develop in the market when AOC has such huge advantages?   1. First, let's take a look at direct attach cable Direct attach cable (DAC) is usually a fix

  40G networks are widely used in data centers. 40G fiber optical transceivers are the mainstream devices for interconnection between data center equipment. So what are the main types of 40g optical transceiver ? What are the differences between them?   The three types of 40G QSFP are 40G QSFP+ SR4, 40G QSFP+ LR4 and 40G QSFP+ PSM LR4. They are all compliant with 40G Ethernet, and data center switches support Infiniband 4xSDR, DDR and QSR. It has four data transmission channels, each with a transmission rate of about 10Gbps, and the simultaneous transmission of four channels can achieve a transmission rate of 40Gbps. It also supports hot-swappable QSFP package with an ultra-low power consumption.   1. 40G QSFP+ SR4 transceiver In 40G network transmission, it is usually used with MPO/MTP connectors. It uses multi-mode optical fiber for transmission. When matched with OM3 multi-mode optical fiber jumper, it can support a transmission distance of 100 meters, and when it is matched with mu

  The Features of SC Quick Connector   In fiber optic cabling, field connector components are required in some cases. Typical examples are point-to-point installation, field installation, or maintenance. Field Mount Connector (FAOC) also known as fast/quick connector, is an embedded fiber optic connector that can be installed and connected in the field. Fiber optic quick connectors are widely used where fast connections are required, providing fast assembly and stable performance. The construction tools are simple and convenient without power supply and easy to operate, which greatly improves the construction efficiency and reduces the labor cost of FTTH.   The SC fast connector is a common type of field assembly connector for FTTX routing networks. What are the features of the SC fast connector?   Ⅰ . Fiber optic quick connectors can be installed on-site with flexible wiring   The optical fiber wiring project of the FTTX user terminal is many and scattered, and the site construction e
