Narrow Linewidth 1550nm DFB Butterfly Laser Diodes
Descriptions:
The NLLD series 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 NLLD 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.
Features:
ITU wavelengths across C-band
100 GHz channel spacing
SONET/SDH OC-48/STM16 ring and meshed applications
Low dispersion provides
Low transient chirp provides unique narrow dynamic spectrum
Excellent long-term wavelength stability eliminates the need for a wavelength locker
Application:
Metro and Long Haul DWDM,100 GHz spaced networks
SONET/SDH OC-48/STM16 ring and meshed applications
Drop-side of DWDM long-haul transport equipment
Optical Test and Instrumentation
Microwave Photonics
CATV networks
