China Telecom Research Institute Completed World First ITU-T GPON System Three-Generation Co-Existence Verification on 50G PON

In July 2023, China Telecom Research Institute and Huawei Technologies Co., Ltd. successfully verified the world’s first ITU-T-compliant three-generation co-existence 50G PON technical solution. The system performance of the prototype fully met the test expectations.
The tested 50G PON prototype uses the GPON/XGS-PON/50G PON triple-mode MPM optical module in QSFP encapsulation format. GPON, XG(S)-PON, and 50G PON ONUs can coexist on the same ODN under the same PON port. The test results sh
