LC25W-B

Data Sheet www.DataSheet4U.com 2.5Gb/s Buried Het Laser 360km Extended Reach With Optional Etalon Stabilization LC25W-B (360km) 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 avelengths available (1527nm to 1605nm) Code reduction with single product for reaches up to 360km 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 1 Data Sheet ww...
