Title:
METHOD AND APPARATUS FOR AN OPTICAL TRANSCEIVER
Document Type and Number:
WIPO Patent Application WO/2021/007706
Kind Code:
A1
Abstract:
The disclosed systems, structures, and methods are directed to an optical transceiver, employing a first optical time domain reflectometer (OTDR) module configured to generate a first OTDR signal, and a second OTDR signal, the second OTDR signal being a delayed version of the first OTDR signal, a first optical supervisory channel (OSC) transmitter configured to generate a first OSC signal, and a second OSC signal, the second OSC signal being a delayed version of the first OSC signal, a first wavelength division multiplexer (WDM) configured to transmit the first OSC signal interleaved with the first OTDR signal on a first optical fiber and a second WDM configured to transmit the second OSC signal interleaved with the second OTDR signal on a second optical fiber.
