Overview: 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 pliant with 50GHz optical channel spacing.
