1,310nm Un-Cooled MQW-DFB
Direct Modulation Laser
FLD3F11BX
FEATURES
• Directly Modulated Un-Cooled MQW DFB Laser
• 2mW Output Power
• 2.5Gb/s, 40km Transmission Span Operation
• Built-in Thermistor, Monitor PD and Optical Isolator
APPLICATIONS
This MQW laser is intended for application in short and intermediate
reach 2.5 Gb/s fiber transmission systems. Transmission spans of up
to 40km are achievable without the need for regeneration.
DESCRIPTION
The MQW (Multiple Quantum Well) DFB Laser is designed for
2.5Gb/s transmission over link lengths up to 40km. It is manufactured in an
industry standard 8-Pin mini-dil package. The module employs a high efficiency
optical coupling system, coupling the laser output through a built-in optical
isolator into a single mode fiber pigtail. The modules also include a monitor
photodiode and thermistor.
