Tunable LD Module with Wavelength Locker FLD5F15CA-K FEATURES: • CW light source with integrated wavelength locker • 13dBm (min.) output power • Tunable over 4 ITU-T grid channels (2.4nm) • Available at C Band ITU-T grid wavelengths between 1528.77-1569.99nm • Wavelength stability better than +/-25pm drift over 20 years operation and (0 - 70°C) case temperature variation • Built-in optical isolator, Thermistor, TEC, Wavelength Monitor Pin, Power Monitor Pin • Polarization preserving (PANDA) fiber APPLICATIONS: Long haul DWDM Metropolitan DWDM applications at 10 Gbs Optical Test Equipment 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 fabryperot 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).
