SM Fiber coupled 1560.61nm 50KHz Narrow linewidth laser
The 50KHz narrow linewidth LD directly modulated external cavity laser is cost effective solution for 2.5 Gbits/s digital transmission in SMF-28 fiber. This is fabricated in a hermetically sealed 14-pin butterfly package that contains thermoelectric cooler (TEC), thermistor, monitor photodiode, optical isolator.
The narrow linewidth LD provides substantially lower dispersion penalty  and lower chirp than a directly modulated DFB. The wavelength stability is assured by design, eliminating the need for wavelength lockers and complex feedback control circuits.
