Description

Integrated Tap Photodiode Isolator

The Integrated Tap Photodiode Isolator (TPDI) integrates the functionality of a miniature polarization insensitive isolator with a tap photodiode for power monitoring in one package. The product provides a more compact solution in EDFA or other modules where both Isolator and monitoring function are needed.
