Multichannel data acquistion system for assessing reliability of fiber optic couplers

With the increased number of fiber-optic couplers in use in network applications, it is imperative that device reliability be ensured. Corning has developed flexible and accurate multi-channel test systems for monitoring performance during environmental testing. One such single-mode system utilizing 90 channels has been demonstrated with a one sigma stability of < 0.004dB over 136 hours of testing.
