FLD5F15CX-J
APPLICATIONS
This laser is intended for the application of 2.5 Gb/s long haul Dense Wavelength Division Multiplexing (DWDM). Transmission spans of 100 km (1800ps/nm) are possible.
DESCRIPTION
The laser is a high power laser capable of 2.5 Gb/s transmission. It is packaged in a "butterfly" type module. 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 module also includes a monitor photodiode, a thermoelectric cooler (TEC), and thermistor. This device is designed for use in DWDM direct modulation transmission systems. Selected wavelengths specified to the ITU-T grid are available. ABSOLUTE MAXIMUM RATINGS (Tc=25C, unless otherwise specified)
