Description
The D372-Type Uncooled Laser Module consists of a
laser diode coupled to a single-mode fiber pigtail.
The device is available in a standard, 8-pin configu-
ration (see Figure 1 and/or Table 1) and is ideal for
long-reach (SONET) and other high-speed digital
applications.
The module includes a narrow linewidth (<1 nm)
DFB-MQW single-mode laser and an InGaAs PIN
photodiode back-facet monitor in a hermetically
sealed package.
This package is optimized for a 25
ance and allows for dc biasing through an internal
bias T. A thermistor has been included for feedback
to board-level bias circuitry, if needed.
