Free Space Isolator
APC’s Free space Isolator is a passive, magneto-optic device
designed to transmit light in one direction while blocking light traveling in
the reverse direction. This function is critical for protecting sensitive
optical components, such as lasers, from back reflections and feedback that can
destabilize or damage the system.
All AC Photonics' products are Telcordia qualification
tested.
