The brief introduction and explanation of the QSFP light module.huawei compatible sfp module manufacture

The rapid use of the Internet and smart terminals has increased the global data volume, which has greatly promoted the development of high -speed router, super computing and storage -centric high -functional supercomputing centers (HPC) and data center markets. Some active cable products are one of the secondary interconnects between these central devices. Research reports from the active optical cable market from CIR show that its market size reaches $ 720 million in 2012. It is estimated that this number has doubled in 2017. When you reach $ 1.9 billion, the prospects are considerable. With the gradual large -scale commercial use of 40G/100G ports, interchange machines and other equipment in data centers, there are more and more demand for high -speed light interconnected products. At present Stop deepening understanding and discussion of high -speed integrated parallel optical modules and high -frequency signals. The key demand of light -linged products is at high speed, high density, low capital, low power consumption. At present, the mainstream high -speed optical interconnected products in the market include 10Gbps SFP+AOC, 40Gbps QSFP optical module+AOC, 56G QSFP optical module+AOC and 120Gbps CXP AOC. The obvious disadvantages of high -speed light interconnection technology and the use of data centers/cloud computing fragmentation in higher bandwidth and lower power consumption are becoming more and more urgent. AOC active optical cables are one of the best treatment solutions to meet this demand. AOC has many obvious disadvantages compared to interconnected copper cables. For example, the transmission power on the fragmented link is lower, the weight is only one -quarter of the direct connection of copper cables, half of the volume is half of the copper cable, and it is in the volume, and in the volume, and half of the copper cable, and in the volume, it is in half of the copper cable. The machine room wiring has better air activity heat dissipation. The curved radius of the optical cable is smaller than the copper cables, and the transmission interval is farther (can reach 100 ~ 300 meters), and the misunderstanding rate of the product transmission function is also better. Ber can reach 10^-15. Compared with the optical receiving module, the AOC active optical cable has no exposed optical interface, and there is no achievement of the cleaning and purification of the optical interface. The fragmented volatility and reliability are greatly improved, and the cost of the machine room is reduced. High -speed optical interconnected products 40Gbps QSFP light module+ AOC and 120Gbps CXP AOC no longer use the constructor design of TOSA/ROSA in traditional insertable transceivers, and use highly integrated array light engine center device technology. The figure below shows a graph of 40G QSFP light module+. The COB (CHIP On Board) integration technology is used on PCBA, which has completed the integrated form -the package is small, the speed is high, and the power consumption is low (QSFP optical module+power consumption is less than 1.5W, CXP power consumption is lower than 2.5W). At the transmitting end, the array optical engine disposes multiple high -speed power channels at the same time, converts it to a multi -way light signal, and then combines these optical signals together. Cloud computing fragmented or the next node of the data center computer room. At the acceptance end, the array optical engine converts the optical signal in the MPO optical cable back to the telegram, and transmits the multi -channel signal to the device for disposal. These products are fully applicable to the INFINIBAND interconnection scenario, which is matched with Ethernet IEEEEEE 802.3ba. In the data center With cloud computing fragmentation categories, array optical engine technology has been widely used in the interconnection between active optical cable products -service players and interchange machines. However, the optical engine technology also faces a large response. The laser of the center is monopolized by most international manufacturers, and the price is expensive. Promote. Based on these reasons, integrated integrated silicon optical technology is the development trend of optical interconnection technology in the future -integrating the entire optical engine on the silicon crystal platform to integrate all necessary functions, complete lower capital, and more complicated processing process. Establish high -density light transmission fragmentation. In the data center machine room, the demand between equipment (services, communication machines, HBA, etc.) of various high -speed light communication ports is connected together to operate together. So how to deal with the interconnection of the two devices? For example, 10G SFP+and 40G QSFP light module+equipment. Light -luster -lit module+4 SFP+AOC optical modules have the best solution for completing and processing QSFP optical modules+SFP+devices.
