What are the 10G SFP+ CPRI optical modules?

CPRI, short for Common Public Radio Interface, transmits baseband I/Q signals to radio units in conventional BS (base stations). 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 does not have a constant temperature environment, and its working environment has a large temperature difference throughout the year. For example, the temperature in the north winter sometimes reaches -30 ℃. In such working environment, the commercial grade (0℃-70℃) optical module obviously cannot work normally. Therefore, the working temperature of the CPRI optical module is industrial grade (-40 ° C to 85 ° C).

1. 10G SFP+ dual fiber optical module

The 10G SFP+ dual fiber optical module, with a maximum speed of up to 10Gbps, complies with SFP+ MSA, 10G Ethernet and 10G CPRI standards, and can transmit up to 80km through OS2 single-mode fiber.

2. 10G SFP+ CWDM optical module

The 10G CPRI CWDM SFP+ series optical modules have eight optional wavelengths (1470nm-1610nm, 20nm interval). They are widely used in the forward network of 10G CPRI mobile base station communication. They are also compatible with 10G Ethernet and can transmit up to 40km through single-mode fiber.

3. 10G SFP+ DWDM optical module

The 10G CPRI DWDM SFP+ series optical modules are widely used in the prequel network of 10G CPRI mobile base station communication. They are compatible with 10G Ethernet and can transmit up to 80km through single-mode fiber.

The 1.25g SFP BiDi single-fiber bidirectional optical module supports the transmission rate of 1.25Gb/s, hot-swappable, bidirectional single-fiber transmission, and supports the temperature range of commercial grade (0 ° C to +70 ° C), expansion grade (-20 ° C to +85 ° C), and industrial grade (-40 ° C to +85 ° C). It is equipped with DDM digital diagnosis and monitoring function.

The BiDi single-fiber bidirectional optical module needs to be used in pairs. Take the 1.25G BiDi optical module with an extension distance of 80 km as an example. If the wavelength of this module is TX149/RX1550nm, the wavelength of the other module needs to be TX1550nm/RX1490nm. The 1.25G BiDi optical module with the same transmission distance of 80 km.

The 1.25G BiDi optical module supports SC ports and LC ports. The SC port needs to connect to the SC connector optical jumper, and the LC port needs to connect to the LC connector optical jumper.
