Cooled header for EML applications, economical alternative to box packages

The SCHOTT TEC TO package is a newly developed transistor outline (TO) which is ideal for laser diodes that require a thermoelectric cooler (TEC). The thermoelectric cooler allows for controlled heat dissipation, which leads to regulated and stable laser wavelengths and higher power signal transmission. 

TEC TO (Pedestal) are suitable for  EML chips in single-channel DWDM in 10Gb Ethernet, CPRI, XGPON and other tunable laser applications.
