Exfo has launched what it claims are the industry’s fastest optical sampling oscilloscopes for existing and next-generation 40G and 100G optical networks.
These high-end test solutions, which can characterise optical networks reaching transmission rates up to 640 Gbps in the lab, are now fully brought to market under the Exfo banner, following the recent acquisition of Swedish-based PicoSolve. They have been integrated into Exfo’s optical test offering, which boasts the largest market share, as recently confirmed by a Frost & Sullivan award.
The PSO-101 is a single-channel oscilloscope that enables eye-diagram analysis and pattern visualisation within existing high-speed optical networks. The PSO-102 is a dual- or quad-channel version, and is purpose-built for next-generation networks with advanced modulation schemes. These schemes, in which data is encoded in both phase and amplitude of the optical carrier, allow network equipment manufacturers to reach ultra-high network speeds such as 40G and 100G using existing dense wavelength-division multiplexing channel spacing, while maintaining resilience to chromatic and polarisation dispersion phenomena.
New software features and options for compliance testing of optical transceivers, including mask-hit analysis (40G masks with user-defined margins) and data filtering (simulation of any type of receiver filter), have also been added to the capabilities of the PSO-100 oscilloscopes.
