DWDM CW DFB Laser Module
Applications
• OC-192/STM-64 DWDM Transmission Systems
Descriptions
• FOL15DCWx series of DFB laser module is designed for l ong haul DWDM appli cations
with external intensity modulator.
• The polarization maintaining fiber pigtail enables to directly connect a modulator without
polarization control. The polarization state of output laser beam is maintained to a
consistent orientation.
• A strained multi-quantum well DFB laser diode chip is integrated with optical isolator,
thermo-electric cooler (TEC), thermistor and power monitor photodiode in an i ndustry
standard hermetically sealed 14 pin butterfly package.
• This laser module compl ies wi th telecom requirements described in TelcordiaTM GR-468
and is m anufactured in an ISOTM9001 certified production line.
Features
• High optical output power up to 40mW
• High side mode suppression rati o(SMSR)
• Selected wavelength according to ITU-T Grid, C and L-band available
• 50GHz spacing available
• Narrow linewidth available

Wavelength values are referenced to vacuum.
50GHz spacing is also available.
Other ITU wavelengths may be available. Please ask to the regional contacts.
Wavelength (λ) and ITU frequency (f) have a relationship of λ[nm] = 299792458 / f [THz] /1000.
FITEL wavelength code is expressed as a 5-digit integer rounded from 100 x f [THz].
