The speed and capacity of information transmission are endless, and the growth momentum of the Internet is still unabated by 2020. High-bandwidth, low-cost optical module solutions have brought great convenience to network upgrades and new networks.
The application of 40G optical module in Ethernet is realized through direct connection of optical fiber cable. OM3 and OM4 are selected for short-distance multi-mode connections, long-distance single-mode modules are realized by single-mode jumpers, and 40G optical modules are connected to the corresponding network equipment to realize the transmission of related data.
According to the 40G protocol standard established by IEEE and MSA, there are two main types of 40G modules on the market: QSFP+ modules and CFP modules. The most common application currently on the market is the QSFP+ module. CFP is relatively rare, so the price is more expensive.
Features of 40G QSFP+ module
1. The 40G QSFP+ module increases the data capacity for transmission, but the volume of the module does not increase, meeting the low-density requirements;
2. In the same bandwidth transmission type, the cost is more economical, and the network construction cost is effectively saved;
3. The 40G QSFP+ module assumes integrated functions in the business connection, simplifies the network architecture, saves the area of the computer room, and reduces equipment stacking, etc.;
4. The data transmission capacity of 40G QSFP+ is improved, and the functions of the core network will be greatly enhanced, thus realizing the overall upgrade of the network.
