研究目的
To demonstrate an integrated LAN-WDM 400-Gb/s (53Gbaud-PAM4) EML TOSA with low power consumption and high performance for 400G 10 km reach application.
研究成果
The developed EML TOSA demonstrates low power consumption (<1.3 W) across a wide temperature range (-5 °C to 80 °C) and meets the 100G/λ MSA specification with TDECQs below 2.45 dB, making it suitable for 400G 10 km reach applications.
研究不足
The study is focused on LAN-WDM specifications for 10 km reach applications, which may not be directly applicable to other wavelength division multiplexing schemes or longer distances without further optimization.
1：Experimental Design and Method Selection:
The study focused on integrating a power dissipation suppressing circuit into the TOSA to achieve low power consumption and high bandwidth.
2：Sample Selection and Data Sources:
Four EMLs were used, mounted on a TEC within a ceramic package.
3：List of Experimental Equipment and Materials:
EMLs, TEC, ceramic package, optical lenses, optical multiplexer, flexible printed circuits (FPCs), and a receptacle.
4：Experimental Procedures and Operational Workflow:
The TOSA was fabricated with EMLs on a TEC, optical system components were assembled, and performance was evaluated through power consumption measurements and optical spectrum analysis.
5：Data Analysis Methods:
Power consumption and TDECQs were measured and analyzed to evaluate performance.
