SILICON PHOTONIC TRANSCEIVER INTEGRATED CHIP FOR PON OLT SYSTEM

WIPO Patent Application WO/2023/221457

A1

A silicon photonic transceiver integrated chip (A1), an optical engine (A2), a central office module, and a PON OLT system board, which are used for a PON OLT system. The transceiver integrated chip (A1) is located in the optical engine (A2) of an OLT, and modulates an optical signal on the basis of a single path, dual paths or four paths of driving electrical signals from an OLT front end. A modulated downlink optical signal is subjected to gain processing by means of the optical engine (A2) and is then transmitted by means of an optical interface of the optical engine (A2). The transceiver integrated chip (A1) performs optical-electrical conversion on an uplink optical signal received by the optical interface of the optical engine (A2) and then sends same to a burst mode receiving and amplifying chipset of the OLT, which is located in an external area of the optical engine (A2), for processing same. The central office module is a module packaged by using SFP-DD/SFP-DD112. The central office module can flexibly configure the rate, is compatible with different standards and application scenarios, and can effectively reduce the cost.
