If the transmission distance is relatively short, we can consider using Walsun 10G DAC high-speed cables for transmission. The length specifications of DAC in the market can be customized based on actual transmission needs, but generally do not exceed 7 meters. If connecting a 10G port with an SFP+ optical interface to a 10G port with a network interface switch for short-distance connections, Walsun 10 Gigabit Ethernet port modules can be used for connections. However, the transmission distance should be within 30 meters, and CAT6A cable needs to be used for the connection.

Product Features

If two switches with SFP+ ports are connected, and the distance is more than 7 meters, we can use 10G AOC active optical cables. The length of the cable can be customized according to the requirements. If the desired length cannot be achieved, you can switch to 10G SFP+ multimode optical modules with OM3 multimode fiber. This connection scheme can achieve a maximum transmission distance of 300 meters.

If the distance between devices exceeds 300 meters, single-mode optical modules can be used. The maximum transmission distance of 10G single-mode optical modules can reach 100 kilometers. Below are the relevant parameters for reference.

In addition to the conventional duplex optical modules mentioned above, there are also 10G CWDM optical modules, 10G DWDM optical modules, and 10G BiDi single-fiber optical modules. However, these types of optical modules are used by telecom operators on the line side and are commonly used in scenarios with ultra-long-distance transmission, such as backbone networks and metropolitan area networks. 10G DAC high-speed cables, AOC active optical cables, and 10G duplex optical modules are applied to data centers, enterprise networks, and other client-side uses.
