1550nm 10mW DFB Narrow Linewidth Laser Diodes
Product Description
Product Detail
1. Summary of 1550nm 10mW DFB Narrow Linewidth Laser Diodes
The 1550nm 10mW DFB Narrow Linewidth Laser Diodes series directly modulated external cavity laser is cost effective solution for 2.5Gbits/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 NLD 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.
