nITLA Series High Power Full C-Band or L-Band tunable laser module

Integrable Tunable

LaserAssembly

(ITLA)

The Pirelli ITLA is a digitally controlled module that allows

network equipment manufacturers to integrate tunable laser sources

into their systems, reducing time-to-market and development costs.

At the core of the ITLA is Pirelli’s DTL, a high

performance external cavity laser capable of tuning over100 channels and designedto meet the requirements oftoday’s high-channel countDWDM metro and regional

telecommunications systems.

With Pirelli’s ITLA,the operator

is capable of fully exploitingthe network. One Pirelli ITLA

can replace each fixedtransmitter, thus dramatically

reducing inventory andsparing costs.

The tunable laser, TelcordiaGR-468-CORE qualified,

does not require moving partsto achieve tunability.
