研究目的
Investigating the performance and reliability of silicon photonics transceivers operating at high temperatures up to 120°C for 5G antenna array systems.
研究成果
The silicon photonics transceiver exhibited a receiver power penalty of about 3 dB when operating from 30°C to 120°C, with potential for improvement through optimized design and materials. This technology shows promise for 5G antenna array systems with further development.
研究不足
The transceiver was not originally designed for operation at temperatures above 70°C, and the reliability is limited by the optical MPO connector and fibre adhesive bonds not rated for 120°C.
1：Experimental Design and Method Selection:
The transceiver was tested inside a climatic chamber at temperatures ranging from 30°C to 120°C, fed by a remote depolarised laser source. The bit error rate (BER) was measured to evaluate performance.
2：Sample Selection and Data Sources:
A Luxtera engineering sample of a 4 × 10 Gbit/s QSFP module was used, designed for operation up to 70°C but tested up to 120°C.
3：List of Experimental Equipment and Materials:
Climatic chamber, Luxtera QSFP transceiver, remote depolarised laser source, pulse pattern generator, optical power splitter, avalanche photodiode (APD) receiver, BER tester.
4：Experimental Procedures and Operational Workflow:
The transceiver was placed in the climatic chamber, connected to the laser source and BER tester. BER measurements were taken at various temperatures to assess performance degradation.
5：Data Analysis Methods:
The BER curves were analyzed to determine the power penalty at high temperatures, and the effects on the receiver and transmitter were segregated.
