Alcatel 1935LMI DD, 20mw PM Fiber DFB Laser
The Alcatel 1935 LMI contains an Alcatel SLMQW DFB laser and is designed for use with external modulation. This module is designed to high power DWDM applications with a spacing between the channels down to 50 GHz without using external locker. The module integrates a wavelength monitoring function in order to allow wavelength stabilization over product lifetime.
Despite of this new feature, the package and the pinout of the new product stays compatible with the previous series (Alcatel 1905LMI) without the integrated wavelength monitoring function, in order to avoid a complete redesign of existing boards. The choice of an analog output for the control signal will leave the freedom for the user to lock the wavelength either with a digital or an analog circuit.
Proper Handling and Operation of DFB Lasers:
DFB laser diodes are highly susceptible to damage from ESD and from temperatures exceeding their specified safe operating range. The user is advised to use care and proper ESD safety practices when handling them to avoid damage to the laser. A properly rated low noise current source, a low thermal resistance mount and a temperature controller should be used for optimal device performance and reliability.
