QDI QDI
introduced the Lambda Light™ narrowly tunable wavelength DFB laser in
2001. Now available with up to 15 mW of optical output power, it is
designed for use as an alternative to conventional fixed wavelength lasers
as a primary or spare laser module for WDM and add/drop applications.
Key features of the Lambda Light are its use of reliable DFB laser
technology and compatibility with existing systems. Field proven
long-term wavelength stability, standard pin-outs on the 14-pin butterfly
package, and cost parity with conventional fixed wavelength DFB laser
module, make the Lambda Light easy to integrate both technically and
economically into today’s point-to-point DWDM, low speed routed
networks, optical add/drop, and precision test/measurement applications.
Lambda Light incorporates phase shifted indium-phosphide (InP) DFB laser chip technology. It is continuously tunable over 4 adjacent ITU wavelengths at 100 GHz spacing or 8 adjacent ITU wavelengths at 50 GHz spacing. Full C band coverage, with center wavelengths from 1530 nm to 1565 nm are available. It is available in a CW version with more than 15 mW of power and a directly modulated version up to 2.5 Gbit/s with more than 5 mW of peak power.
