4G SFP Checker

4G SFP Checker can test bit error rate and read the serial ID.
4G SFP Checker can test bit error rate and read the serial ID.

The SFP Checker integrated the Bit Error Rate Tester, Optical Power Meter, Digital Diagnostics Monitor for SFF-8472, and EEPROM R/W into a portable pocket size box for the SFP transceiver (Mini-GBIC) which is most popular in optical communication system.

It provides the test environment for OC-3 (STM-1), OC-12 (STM-4), OC48 (STM-16), 100base / 1000base , and 1x / 2x / 4x Fiber Channel. Completely setting the test parameters through a friendly Graphical User Interface (GUI) with single USB connector or simply testing the SFP with LED indicators on the top panel of the checker through an USB power bank. An optional power meter module can be installed for optical power measurement and one loopback port for bidirectional transceiver testing.
