D372-21GS D372-Type Digital Uncooled DFB Laser Module

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 conﬁguration (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 lin.
