1300-1550nm DFB Laser Diodes Optical transmitters required for Dense Wavelength Division Multiplexing (DWDM) applications Enables increased bandwidth by increasing the number of optical channels per fiber Enabled by thermally controlling the laser to very tight temperature tolerances with TECs.

980nm and 1480nm Pump Lasers Thermoelectric coolers are used to temperature tune the pump laser wavelength to the absorption wavelength of the media being optically pumped (EDFA Optical Amplifiers, Diode Pumped Lasers)

The Emerging "Passive" Components for the "All Optical Network" Thermoelectric coolers are used to stabilize critical temperature sensitive components: Arrayed Wave Guides (AWGs), Optical Multiplexers (MUX and DeMux), Optical Switches and Varible Optical Attenuators (VOAs)
