• PM fiber
The EM4 278 single mode, uncooled 976 nm pump lasers simplifies next generation erbium doped fiber amplifier (EDFA) designs by eliminating the need for large, less efficient, and costlier electric supplies. It is wavelength stabilized by a fiber Bragg grating (FBG) which maintains stable performance over temperature ranges of 10 to 75 °C and power ranges of 50 to 200 mW.
The hermetically sealed 8 pin mini-DIL package includes thermistor, monitor photodiode and UniDry™ getter. The fiber Bragg grating precisely locks the center wavelength over extended power and temperature range. By eliminating the thermoelectric cooler, next generation EDFA designs, particularly the thermal and control circuitry, benefit from the pump modules smaller size.
