  Anyonic Fabry-P\'erot and Mach-Zehnder interferometers have been proposed
theoretically and implemented experimentally as tools to probe electric charges
and statistics of anyons. The experimentally observed visibility of
Aharonov-Bohm oscillations is maximal at a high transmission through an
interferometer but simple theoretical expressions for the electric currents and
noises are only available at low visibility. We consider an alternative version
of a Mach-Zehnder interferometer, in which anyons tunnel between co-propagating
chiral channels on the edges of quantum Hall liquids at the filling factors
$n/(2n+1)$. We find simple exact solutions for any transmission. The solutions
allow a straight-forward interpretation in terms of fractional charges and
statistics.
