tail
s Wide operating temperature range:
–40 °C to +85 °C
s No TEC required
s 25 input impedance
s High output power: typically 1.0 mW peak power
coupled into single-mode fiber; 0.2 mW versions
available
s Hermetically sealed active components
s Internal back-facet monitor
s Qualification program: Telcordia Technologies * TA-
983
Benefits
s Easily board mounted
s Gull wing leads
s No additional heat sinks required
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 configu-
ration (see Figure 1 and/or Table 1) and is ideal for
short-reach and other high-speed digital applica-
tions. It is developed specifically for 2.5 Gbits/s appli-
cations.
The module includes a multiquantum-well Fabry-
Perot (MQW F-P) laser and an InGaAs PIN photo-
diode back-facet monitor in an epoxy-free, hermeti-
cally sealed package.
