With the rapid development of the modern Internet industry, the scale of the global data center continues to expand and upgrade. Both the internal interconnection and access network need to use a large number of optical modules, which makes the optical module the fastest-growing product in the optical communication market. High speed, high density, low power consumption and low cost are the primary goals of the current data center construction. The demand for 25G optical modules and 25G cables is a leap in this market environment. Today let’s learn about 25G network cabling.

25G SFP28 DAC: Link length 1-5m

25G SFP28 DAC high-speed cable has excellent attenuation performance and low delay performance, which makes the signal transmission correct and improves the transmission speed. 25G SFP28 to SFP28 DAC is a very cost-effective short-distance link transmission solution. It can establish 25G link through the SFP28 port of the switch, which is widely used in data center or Supercomputing Center system scenarios.

25G SFP28 AOC: Link length 70-100m

The transmission distance of 25G SFP28 AOC can reach 70m when use with OM3 multimode fiber, and 100m use with OM4 multimode fiber. They are suitable for short-distance data communication and interconnection applications, and provide an economic and effective way for the connection between the rack and adjacent racks. They are widely used in high-speed, high-density and low-power data center networks. Yitian optical communication can provide users with 25G DAC / AOC / optical modules and other products as well as efficient optical network application connection solution.

SFP-25G-SR optical modules: Link length 100m

The transmission wavelength of the SFP-25G-SR optical module is 850nm. It is used together with OM3 / OM4 multimode fiber, with a transmission distance of 100m, belonging to the short distance transmission optical module. The SFP-25G-SR optical module is mainly used in 25G Ethernet switches, routers, network interface cards and storage network devices.

SFP-25G-LR optical modules: Link length 10KM

The transmission of SFP-25G-LR optical module is 1310nm, which is usually used with single-mode fiber. The transmission distance can reach 10km, and it is suitable for long-distance data transmission. The SFP-25G-LR optical module uses DFB laser.

25G SFP28 BIDI optical modules: Link length 10-20KM

When 25G SFP28 BIDI optical module is used with single-mode optical fiber, the transmission distance can reach 10km, which can be extended to 20km according to different power budget.

The above is about the wiring of 25G network. 25G optical module can provide the most energy-saving way to meet the growing demand of data center network. 25G SFP28 AOC/25G SFP28 DAC is the most cost-effective solution for short distance connection of 25G ToR switch. In addition, if you want to realize the long-distance connection of 25G tor switch, you can use 25G SFP28 optical module and patch cord to achieve.
