Rapid evolution in transceiver technology
Whether driven by cost, power, space, or growing bandwidth demands, pluggable transceivers are evolving quickly. Predicting how long a given transceiver will remain in use before being replaced is difficult, making hardware turnover inevitable.
At the same time, network operators and data centers must support existing technologies while preparing for new rates and innovations—without constant forklift upgrades. Whether it’s SFP and SFP+ (for rates up to 10G), QSFP28 and CFP4 (for 100G), or SFP28 (for 25G), integrating, testing and validating these technologies is a major challenge. The smart approach is to invest in versatile test solutions that keep pace with network evolution.
Industry’s first field portable test unit supporting 100ZR coherent interface
- 100 Gbit/s DWDM wavelengths with reach up to 300 km
- Low power coherent QSFP28 transceiver (< 5 watts) for easy migration and deployment
- Use cases: Metro and edge network aggregation, 5G mobile backhaul and middle mile connectivity for rural broadband

Test today's transceivers.
Be ready for tomorrow's.
EXFO's Open Transceiver System (OTS), an innovative, evolutionary design concept enabling any transceiver (now or future) to fit an EXFO test solution.
- Experience ultimate flexibility—swap out OTS modules right in the field, lab or on the production floor, choosing only the ones needed for the applications, rates or technologies under test.
- Reduce costs significantly by eliminating the need to purchase an entirely new test unit. 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.
