1310/1480/1550 nm 2-in-1 Isolator

The 1310/1480/1550 nm 2-in-1 Isolator offers excellent temperature stability, and low IL loss.
  • Product Detail

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 Isolator offers excellent temperature stability, low IL loss, high isolation, low temperature dependence and  great space saving.
