I. Basic Definition of TEC TEC stands for thermoelectric cooler, a miniature semiconductor solid-state temperature control element. Lasers in optical modules are highly sensitive to temperature; temperature fluctuations can easily cause problems such as wavelength shift, power instability, and signal degradation. Therefore, mid-to-high-end high-speed optical modules commonly incorporate miniature ...
