Data Sheet
2.5Gb/s Buried Het Laser 175km Reach
With Optional Etalon Stabilization
LC25W-A (175km)
This laser module employs the Bookham strained layer
MQW Buried Heterostructure DFB laser chip, and has been
designed specifically for use in Wavelength Division
Multiplexed (WDM) 2.5Gb/s long distance optical fiber
trunk systems.
The device is packaged in a hermetically sealed 14-pin
butterfly package incorporating an isolator and monitor
photodiode for control of the power of the laser over life and
all operating conditions. The device is available with a number
of power options depending on application and link
span requirements.
The optional internal Etalon wavelength stabilization and low
chirp performance makes this product compliant with 50GHz
optical channel spacing.
Features:
• 2.5Gb/s operation
• +/-95pm wavelength stability over life without
Etalon locker
• Optional Etalon wavelength stabilization provides
50GHz optical channel spacing compliance for interlay
or future upgrade
• Narrow spectral line-width
• Internal TEC with precision NTC thermistor for
temperature control
• Entire C & L-band ITU wavelengths available
(1527nm to 1605nm)
• Code reduction with single product for reaches
up to 175km
• GaInAsP SLMQW DFB single frequency laser chip
• InGaAs monitor photo-diode
• Hermetically sealed 14-pin butterfly package with
optical isolator
• RoHS compliant
Applications:
• WDM
• On-off ramps
• Long-Haul
• DWDM on ITU Grid
