1,550nm DWDM Direct
Modulation DFB Laser
FLD5F15CX-E
wFwwE.DAatTaSUheRet4EU.Scom
• Direct Modulation Laser for WDM systems
• Optimized for Long Distance Transmission (Dispersion 1800ps/nm)
• Peak wavelength 1527.99 to 1563.05nm (C-band: 191.8 to 196.2THz,
100GHz spacing)
• Output Power: 2mW
• 14-pin Butterfly type package
• Built-in Optical Isolator, Power Monitor PIN-PD, Thermistor,
and Cooler
• Single Mode Fiber
APPLICATIONS
This laser is intended for the application of 2.5 Gb/s
long haul Dense Wavelength Division Multiplexing (DWDM).
Transmission spans of 100km (1800ps/nm) are possible.
DESCRIPTION
The laser is capable of 2.5 Gb/s transmission. It is packaged in a “butterfly” type module.
The module employs a highly stable 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.
