10G SFP+ optical switch has been widely used in data centers and enterprises. In this blog, ETU-LINK lists the connection schemes that accessible 10G SFP+ ports? And under what circumstances is it more appropriate to choose which one.

Firstly, if the transmission distance is relatively close, we can consider using ETU 10G DAC cables for transmission. The length specifications of DACs on the market can be customized according to actual transmission needs, but generally do not exceed 7 meters. If it is a short distance connection between a 10G SFP+ optical port and a 10G Ethernet switch, the ETU 10 Gigabit Ethernet Module (ES-T5-R) can be used for connection. However, the transmission distance is within 30 meters and CAT6A super Category 6 network cable connection is required.

If two switches with SFP+ ports are connected and the distance between them is more than 7 meters, we can use ETU 10G AOC active optical cable. The length of the cable can be customized according to the needs. If you can't reach the length distance you want, you can use 10G SFP+ multi-mode Optical module with OM3 multi-mode optical fiber instead. The longest transmission distance of this connection scheme can reach 300 meters.

If the equipment spacing is more than 300 meters, a single mode Optical module can be used. The longest transmission distance of 10G single mode Optical module can reach 100KM. The following are relevant parameters for reference only.

In addition to the conventional dual fiber Optical module listed above, the 10G single-mode Optical module also includes the 10G CWDM Optical module, the 10G DWDM Optical module, and the 10G BiDi single fiber Optical module. However, these types of Optical module are used by operators on the line side and are commonly used in ultra remote transmission scenarios such as Backbone network and Metropolitan area network. 10G DAC high-speed cable, AOC active optical cable, 10G dual fiber Optical module are used in data center, enterprise network and other clients.
