At present, in the field of optical communication, almost all 100G switch interfaces are QSFP28 interfaces. In order to realize multi-channel 100G long-distance point-to-point dual fiber transmission, it must be applied to the transmission scheme of 100G DWDM. The coherent 100G DWDM transmission system is a new application for metro networks and a better solution for high-speed and high-capacity transmission. <\/span><\/p>\n\n\n\n

T<\/span>he application of communication technology and the explosive growth of cloud data traffic put forward higher transmission performance requirements for the physical layer as the basis of the whole communication system, promote the development of coherent optical communication, and further improve the effect of total communication capacity and transmission distance on the basis of the original WDM system.<\/span><\/p>\n\n\n\n

The 100G coherent DWDM enables customers to expand or upgrade existing 10G\/40G networks to 100G applications without changing the original infrastructure, so as to achieve higher bandwidth and spectrum utilization.<\/span><\/p>\n\n\n\n

100G DWDM QSFP28 vs 100G CFP\/CFP2 Coherent solution<\/b><\/strong><\/span><\/p>\n\n\n\n

In the traditional application scheme of 100G DWDM, the 100G DWDM optical modules are mainly packaged in CFP or CFP2, and the switch interfaces are QSFP28<\/a>. In order to realize inter-connection, the technology of active equipment 100G QSFP28 to 100G CFP\/CFP2 is required, as shown in the following figure:<\/span><\/p>\n\n\n\n

<\/span><\/p>\n\n\n\n

However, the traditional CFP\/CFP2 coherent optical transmission mode, whether using active 100G QSFP28 to 100G CFP\/CFP2 equipment or 100G CFP\/CFP2 coherent optical module, has serious technical barriers, resulting in high price and cost. Coupled with the impact of COVID-19 in the past 2 years, the global optical chips are out of stock, and prices are rising, resulting in higher and higher costs of optical modules and even shortages.<\/span><\/p>\n\n\n\n

Therefore, in order to cope with the market dilemma, FiberMall<\/strong> launched the optical module packaged with 100G DWDM QSFP28<\/a>, which can be directly inserted into the QSFP28 interface of the 100G switch, and then cooperate with the scheme of dispersion compensation DCM and DWDM fiber amplifier (EDFA), which can replace the traditional transmission scheme of 100G CFP\/CFP2 coherent light.<\/span><\/p>\n\n\n\n
