With the rapid development of the modern Internet industry, the scale of the global data center has been continuously expanded and upgraded. Both the internal interconnection and the access network require a large number of optical modules, which makes the optical module become the fastest growing product in the optical communication market. High speed, high density, low power consumption and low cost are the primary goals of data center construction. The demand for 25G optical module and 25G high-speed cable has made a quantum leap in this market environment.

The 25G optical modules provided by ETU-Link mainly include SFP-25G-SR and SFP-25G-LR optical modules.

SFP-25G-SR optical module is a high-performance short-range data communication module with the wavelength of 850nm, it is using VCSEL laser and mainly used with OM3\OM4 multi-mode fiber, the maximum transmission distance of 100m is suitable for short-range data transmission.

SFP-25G-LR optical module is a high-performance long-distance data communication module with the wavelength of 1310nm. It is using DFB laser and mainly used with single-mode fiber. The maximum transmission distance can reach 10km is suitable for long-distance data transmission.

25G optical module and switch matching solution

The 25G optical module is mainly used in conjunction with a 25G Ethernet switch to implement 25G Ethernet. The following are specific solutions.

The 25G high-speed cable consists of a passive copper core cable and two optical transceiver modules of SFP28-SFP28 interface. The transceiver module looks like a optical module, but there is no laser installed inside.The 25G high-speed cable can replace the 25G optical module for short distance data transmission, because there is no laser installed and the price is much lower than the 25G optical module, it is a more common and cost-effective solution for short distance interconnection applications of 25G switches in data centers.

The 25G high-speed cable can be directly connected to the 25G Ethernet switch to realize the 25G Ethernet network deployment. Compared with the 25G optical module, the 25G high-speed cable is more suitable for the short-distance direct connection within the frame of the data center, and generally length is 1~7 meters will be better.

Each optical module and each high-speed cable provided by ETU-Link have gone through multiple strict quality inspection processes, and there are perfectly compatible with major mainstream brands. They are the best choice for you to solve network cabling.If you have any doubts about the wiring solution, please feel free to contact us.
