UNIVERSAL TEST SYSTEM FOR TESTING ELECTRICAL AND OPTICAL HOSTS

摘要

According to an example implementation, a universal tester includes a host interface slot connected to a first pluggable host card during an electrical test mode of operation to provide a stressed electrical signal to a host under test. The host interface slot is connected to a second pluggable host card during an optical test mode of operation, the second pluggable host card including an electrical-optical conversion block to convert a stressed electrical signal to a stressed optical signal that is provided to a host under test. A stressor generator may operation in pass-through mode or a loop-back mode.
