40G/100G QSFP AOC Checker


The QSFP Checker is an instrument which can help you to test QSFP,QSFP+ module ,QSFP AOC,QSFP+ AOC,QSFP DAC,QSFP+ DAC

It can help you to read the internal memory EEPROM of the modules and display details of the EEPROM (such as the Part Number, Vendor Name, description and range.), monitor all DDM information.  You can change the EEPROM if you know the module password . In addition it can measure the power of the module.

The QSFP Checker combines the Serial Pattern Generator, Bit Error Rate Analyzer. It provides common transmission rate for 40G and 100G.

The friendly graphic user interface (GUI) provides clear monitoring for bit error rate, bit error counter, time, status, power of the module, selection of data rate and PRBS pattern.

Working Mode

1. 40G QSFP+

In this mode, QSFP module, QSFP AOC, QSFP DAC can be tested. Two modules at the same time, one by one, single channel by single channel, all are supported.

In addition, you can use two “QSFP Checker” if the AOC or DAC can’t be inserted into one QSFP Checker. But in this mode, two QSFP Checkers connected to one PC is not supported.


2. 100G QSFP28, 112G QSFP28

100G QSFP28, 112G QSFP28 are used to test 100G/112G QSFP28 module, AOC, DAC

In these two modes, only the QSFP2 Port is used, QSFP1 port is no function include DDM, power measure, read and write EEPROM. Two QSFP Checkers must be used when 100/112G QSFP28 AOC/DAC is tested. You can connect the two QSFP Checkers to   two PC.


3. 100G QSFP28_ A, 112G QSFP28_A

These two modes are only used when you connect two QSFP Checker to one PC

Otherwise they are no function


4. Without PC

The QSFP Checker can working independently .You can choose the work mode from the GUI and save it to the QSFP Checker (Factory setting is 40G), then the Checker can work as you wanted.  The QSFP Checker will not change its working mode even if it is power down, you can get the main message from the four LED, such as working mode, Bit Error test is OK or NG.
