Classification: CPC H | IPC H

Claim 0:
1. An optoelectronic module comprising:
an optical receiver optically coupled with an optical fiber, the optical receiver configured to receive time synchronization signals from the optical fiber, wherein the time synchronization signals are amplitude modulated and are received along with received data signals; and
a time synchronization signal detection module communicatively coupled to the optical receiver, the time synchronization signal detection module configured to receive the time synchronization signals that are transmitted through the optical fiber and detect amplitude modulations to recover the time synchronization signals, the time synchronization signal detection module comprising:
an amplifier;
a low pass filter, wherein the input of the filter is coupled to the output of the amplifier; and
a limiting amplifier, wherein the sole input of the limiting amplifier is coupled to an output of the low pass filter.
