Description
The D374-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 configuration (see Figure 1 and/or Table 1) and is ideal for  short-reach and other high-speed digital applications. It is developed specifically for 2.5 Gbits/s applications.
