Abstract
The present invention relates to a system for measuring the optical coupling between cores of a multicore fiber which comprises transmitter capable of transmitting a train of pulses of controlled frequency and width into one end of a core of a multicore fiber, and detection capable of detecting the signal received at the same end of at least one other adjacent core of the multicore fiber, with a controlled time window close to the transmission pulse duration and with a delay between 0 and the transmission period.
