The Twin Isolator integrates two independent isolators into one standard isolator package and is excellently suited for EDFAs or instrumentation designs where two or more isolators are used. The Twin Optical Isolator offers excellent temperature stability, low insertion loss, high isolation, low temperature dependence and great space saving.
