ISO – Isolator
DESCRIPTION
General Photonics' pigtailed isolators are available in both polarization independent versions (SM fiber) and polarization maintaining versions (PM fiber). All models pass light forward with minimal loss while isolating systems from light travelling in the opposite direction. With double stage isolation, up to 52 dB of isolation is possible. Models are available with or without connectors. General Photonics also offers isolators in the NoTail™ package (NISO Models).
