A371-Type Analog Uncooled Isolated

DFB

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.

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
