Technology evolves at a rapid-fire pace. That’s why we’ve built an easy-to-use glossary to help you better understand the terms, technologies and trends that impact your business.


EXFO’s Open Transceiver System (OTS) is an innovative, evolutionary design enabling any transceiver (now or future) to fit into an EXFO test solution. Benefits include:

  • Experience ultimate flexibility—swap out OTS modules right in the field, lab or on the production floor, choosing only the ones needed for whichever applications, rates or technologies under test.
  • Save tens of thousands of dollars by eliminating the necessity to completely replace an expensive testing module. Instead, change a less costly OTS module and extend the life of testing equipment.
  • Support multiple transceiver types simultaneously with a future-proof architecture designed to handle both current and upcoming high-speed transceiver technologies as they are developed and launched.
