Description
The A371-Type Uncooled Isolated 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 CATV applications.

FEATUREs
■ Eight-pin package suitable for CATV applications
■ Narrow linewidth, distributed-feedback, multiquantum-well (DFB-MQW)1.3 µm laser with single-mode fiber pigtail
■ Wide operating temperature range: –40 °C to +85 °C
■ Frequency range up to 1.0 GHz
■ No thermoelectric cooler required
■ Single- and double-isolated versions available
■ High output power: typically 2.0 mW peak power coupled into single-mode fiber
■ Hermetically sealed active components
■ Internal back-facet monitor
■ Qualification program: Bellcore TA-983

APPLICATIONs
■ Video and data applications
■ Downstream telephony and data
■ Return path systems
■ Mixed analog and digital modulation
■ Telecommunications

Benefits
■ Easily board mounted
■ Requires no lead bending
■ No additional heat sinks required
■ Pin compatible with industry-standard, 14-pin laser module
■ Highly efficient DFB-MQW laser structure allows for lower threshold and drive currents, and reduced power consumption
■ High output power allows for longer system spans, more fiber splits, and greater tolerance of fiber and connector quality
■ Internal isolator minimizes spurious noise
