The Multiple Application Platform (MAP) General Purpose Light Source (mSRC-C2) is a family of stabilized, fibercoupled, fixed wavelength emitters with coverage of the key Telecom/Datacom wavelength bands – 850, 1300,1310, 1490, 1550, and 1625nm. They share a common interface that can hold FP laser, LED and SLED sources. They can perform at both constant power and constant current operating modes with 10 dB of power tuning range. The many variants of the mSRC-C2 enable a broad array of applications and encompass several different emitter types. The emitter types have a specific set of spectral properties that make them ideal for different metrology applications.
