Description

The D572-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 D572-20SS includes a narrow linewidth (<1 nm) DFB-MQW single-mode laser and an InGaAs PIN photodiode backfacet monitor in a hermetically sealed package.
This package is optimized for a 25 Ω input imped-ance and allows for dc biasing through an internal bias tee. A thermistor has been included for feedback to board-level bias circuitry, if needed.
