Data Sheet
2.5 Gb/s Buried Het 4x100GHz Tunable Laser with
Etalon Stabilisation and extended reach option
LC25ET
This laser module employs the Bookham gain coupled
SLMQW buried heterostructure DFB laser chip, and has been
designed specifically for use in Wavelength Division
Multiplexed (WDM) 2.5 Gb/s long distance optical fibre
trunk systems.
The device is packaged in a hermetically sealed 14-pin
butterfly package incorporating an isolator and locking optics
to lock and stabilise wavelength and power of the laser
over life.
The module is tunable by means of the internal thermo-electric
cooler over four adjacent 100 GHz ITU WDM channels.
The device is available with a number of power options and
wavelength schemes, which are customizable to individual
customer specification. The internal etalon wavelength
stablilisation and low chirp performance makes this product
compliant with 50GHz optical channel spacing.
Features:
• 2.5 Gb/s Operation
• Tunable over four separate channels at 100 GHz
channel spacing
• Integrated wavelength locking optics
• Entire C band ITU wavelengths available
(1528 to 1563 nm)
• Narrow spectral line-width
• Hermetically sealed 14-pin butterfly package with
optical isolator
• Internal TEC with precision NTC thermistor
• Extended reach performance up to 360 km with low
dispersion penalty
• 50GHz optical channel spacing compliant for interlay
or future upgrade
• RoHS compliant
Applications:
• Optical Service Channel (OSC) applications in DWDM
transmission systems using optical amplifiers.
