DESCRIPTION:
The Fujitsu Tunable LD module with Wavelength Locker (FLD5F15CA-K) is a high power
CW laser (13dBm) with polarization maintaining fiber. It is intended for use with an external
modulator. The laser can be wavelength tuned across a 2.4nm range (4 ITU-T 100Ghz
spaced channels) via adjustment of the chip temperature with the included TEC. The tuned
wavelength can be locked onto the desired ITU-T grid channel via use of the included fabry-
perot etalon. This laser is available at any of the 52 ITU-T wavelengths in the C band
(1528.77-1569.59nm). The device comes in a standard 14-pin butterfly package, operates
between 0-70°C, and requires 120mA of drive current (typical).
