| Polarization Insensitive Twin Isolator | |
| Fibre coupled twin isolator | |
| Polarization insensitive isolator, twin Isolator integrates two independent isolators into one standard isolator package and is excellently suited for EDFA 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. |
