CPRI is the abbreviation of common public radio interface. CPRI plays the role of transmitting baseband I / Q signals to radio units in traditional BS (base station). CPRI has efficient and flexible I / Q data interfaces for various standards, such as GSM, WCDMA, LTE, etc.

Unlike the data center, the CPRI optical module used in the base station has a constant temperature environment, and its working environment has a large temperature difference all year round. For example, in winter in the north, the temperature is sometimes minus 30 ℃. In such a working environment, the commercial optical module (0 ℃ - 70 ℃) obviously can not work normally, Therefore, the working temperature of CPRI optical modules is industrial grade (- 40 ℃ - 85 ℃).

Next, ETU-LINK will introduce the 10G SFP+ CPRI optical modules applied to the mobile base station communication preamble network.

10G SFP+ dual fiber optical module

The 10G SFP+ dual fiber optical module of ETU-LINK has a maximum speed of 10Gbps, complies with SFP + MSA, 10G Ethernet and 10g CPRI standards, and the transmission distance through OS2 single-mode optical fiber can be up to 80km.

10G SFP+ CWDM optical module

The 10g CPRI CWDM SFP + series optical module of ETU-LINK has 8 optional wavelengths (1470nm-1610nm, with an interval of 20nm). It is widely used in the forward transmission network of 10G CPRI mobile base station communication. At the same time, it is compatible with 10G Ethernet, and the transmission distance through single-mode optical fiber can reach 40km.
