Unidirectional Integrated Tap Photodiode (UTPD)
The Unidirectional Integrated Tap Photodiode (UTPD) integrates the functionality of an optical coupler and a photodiode for optical network's power monitoring. The unidirectional feature allows the PD to respond power from input port only. It can be applied for channel power monitoring in DWDM system, optical fiber line auto switch protection equipment (OLP), re-configurable optical add/drop multiplexer (OADM), and gain/attenuation monitoring in EDFA, etc.
