Exfo Electro-Optical Engineering Inc. has acquired Sweden’s PicoSolve Inc., a private test and measurement company offering optical sampling oscilloscopes for 40G and 100G R&D, manufacturing and deployment applications.

Founded
in 2004 by researchers at Chalmers University of Technology in
Gothenburg, PicoSolve provides high-speed optical sampling
oscilloscopes to network equipment manufacturers (NEMs) involved in the
design and production of next-generation optical networks. Network
service providers (NSPs) will also require such high-end test equipment
for their deployment initiatives, says Exfo.



Advanced
modulation schemes, in which data is encoded in both phase and
amplitude of the optical carrier, allow NEMs to reach ultra-high
network speeds using existing DWDM channel spacing, says Exfo, while
maintaining resilience to chromatic and polarization dispersion
phenomena. Full characterization of this ultra-high-speed encoding
represents a significant test and measurement challenge for both NEMs
and NSPs.



PicoSolve
currently has the only bit rate-independent test solution that can
measure such phase- and amplitude-modulated signals with a measurement
bandwidth of more than 500 GHz, adds the company, yielding a
sub-picosecond temporal resolution.
