A371-Type Analog Uncooled Isolated
DFB FastLight Laser Module
The low-profile A371-Type Analog Laser Module is ideally
suited for CATV applications, particularly in systems where
long spans and superior reliability are the critical consider-
ations.
Features
s Eight-pin package suitable for CATV applications
s Narrow linewidth, distributed-feedback,
multiquantum-well (DFB-MQW)1.3 µm laser with
single-mode fiber pigtail
s Wide operating temperature range:
–40 °C to +85 °C
s Frequency range up to 1.0 GHz
s No thermoelectric cooler required
s Single- and double-isolated versions available
s High output power: typically 2.0 mW peak power
coupled into single-mode fiber
s Hermetically sealed active components
s Internal back-facet monitor
s Qualification program: Bellcore TA-983
Applications
s Video and data applications
s Downstream telephony and data
s Return path systems
s Mixed analog and digital modulation
s Telecommunications
Benefits
s Easily board mounted
s Requires no lead bending
s No additional heat sinks required
s Pin compatible with industry-standard, 14-pin laser
module
s Highly efficient DFB-MQW laser structure allows
for lower threshold and drive currents, and reduced
power consumption
s High output power allows for longer system spans,
more fiber splits, and greater tolerance of fiber and
connector quality
s Internal isolator minimizes spurious noise
