Title:
OPTICAL RECEIVER, OPTICAL TRANSCEIVER COMPRISING THE SAME, AND METHOD OF PROTECTING A PHOTODETECTOR IN THE OPTICAL RECEIVER
Document Type and Number:
WIPO Patent Application WO/2018/090337
Kind Code:
A1
Abstract:
An optical or optoelectronic receiver, an optoelectronic transceiver including the same, and a method and system for protecting a photodetector in the same are disclosed. The method of protecting a photodetector generally includes providing a control voltage to the photodetector so that a current flows through the photodetector, and determining that a transient event has occurred or a transient state exists in the receiver. During the transient event or transient state, the method maintains the control voltage at a normal operating voltage when the current through the photodetector is at or below a predetermined threshold current, and switches the control voltage to a safe mode voltage when the current through the photodetector is above the predetermined threshold current.
