10G/25G SFP+ Checker

10G SFP+ Checker can measure optical power, read internal memory EEPROM and monitor the DDM information.
10G SFP+ Checker can measure optical power, read internal memory EEPROM and monitor the DDM information.

The 10G/25G SFP+ Checker can help you to read the internal memory EEPROM of the SFP+ and displays details EEPROM contents registered into EEPROM such as the part number, vendor name , wavelength, description, and range.

Inserted a DDM SFP+ that is with digital diagnostics, the SFP Checker can be used to monitor the all DDM information. With optical power meter module, you can measure the real output power of SFP transceiver.

The 10G SFP+ Checker is an instrument which combines the Serial Pattern Generator, Bit Error Rate Analyzer, and Optical Power Meter within a compact size for both optical telecommunication and data communication. It provides common transmission rate for 8x Fiber Channel, OC-192, and 10G Ethernet. The optical power can be measured by plugging in an optional optical sensor module.

The friendly graphic user interface (GUI) provides clear monitoring for bit error rate, bit error counter, timer, SFP status, optical power from the sensor module and selection of data rate and PRBS.
