2.5 Gb/s Buried Het 4x100GHz Tunable Laser
with extended reach option
LC25T
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 monitor photodiode for
control of the power of the laser over life and all operating
conditions.
The module is tunable by means of the internal thermo-electric
cooler over four adjacent 100 GHz ITU WDM channels with a
case temperature of 70°C, or over two adjacent 100 GHZ
channels with a case temperature of 85°C
The device is available with a number of power options and
wavelength schemes, which are customizable to individual
customer specification.
Features:
• 2.5 Gb/s Operation
• Tunable over four separate channels at 100 GHz
channel spacing
• +/-95pm wavelength stability over life
• 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
• RoHS compliant
Applications:
• Cost effective metropolitan or long haul networks
• Stock inventory / Spares reduction
• Network protection
• Low-speed routing / Networks reconfiguration
