DESCRIPTION:
The Fujitsu Tunable LD module with Wavelength Locker (FLD5F15CA-Q) is a high power
CW laser (16dBm) 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 L band
(1570.41-1608.76nm). The device comes in a standard 14-pin butterfly package, operates
between 0-70°C, and requires 300mA of drive current (typical).

Note 3. Wavelength at lock point is longer than Im2 peak. (Increasing wavelength shall give
a decrease in wavelength monitor current) The value is written in frequency: f=c/λp, c=2.99792458*10
