EUDYNA FLD5F20NP

1,550nm Modulator
Integrated DFB Laser
FLD5F20NP
FEATURES
• Modulator Integrated DFB Laser Diode Module
• CW operation of DFB laser section
• Modulation voltage applied only to modulator section
• High speed butterfly package with GPO connection
• Built-in optical isolator, monitor photodiode, thermistor, and
thermo-electric cooler
APPLICATION
This MI laser is intended for intermediate reach applications (≤40km)
at 10Gb/s.
DESCRIPTION
The Modulator Integrated DFB Laser (MI DFB Laser) has an electro-absorption modulator
monolithically integrated with a conventional Distributed Feed-Back (DFB) laser. The modulation
voltage is applied to the modulator section while the laser section operates CW allowing extremely low
wavelength chirping. Extinction ratios of more than 10 dB can be achieved with 2.6 Vp-p modulation.
The MI laser is installed in a butterfly type package. The module incorporates a highly stable
optical coupling system. The module includes an optical isolator, monitor photodiode,
thermistor and a thermo-electric cooler.
