DESCRIPTION:
The Fujitsu Tunable LD module with Wavelength Locker (FLD5F6CA-C) is a high power CW
laser (13dBm) with polarization maintaining fiber that is intended for use with an external mod-
ulator. 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 wave-
length can then 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 80mA of drive current (typical).
