Description

The D371-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 config-

uration (see Figure 1 and/or Table 1) and is ideal for

long-reach (SONET) and other high-speed digital

applications.

The laser diode is a narrow linewidth (<1 nm) DFB-

MQW single-mode laser and an InGaAs PIN photo-

diode back-facet monitor in an epoxy-free, hermeti-

cally sealed package.
