This unit

The EXFO IQS-2123BLC-EI is a dual-wavelength optical light source module engineered for fiber optic network loss testing. Operating at 1310 nm and 1550 nm, this Fabry-Perot laser source delivers variable output power across a 10 dB range with 0.1 dB increment resolution. The module integrates steady drive circuitry to maintain exceptional stability and couples precision optical components for efficient, low-loss output. It slots directly into IQS-600 Intelligent Test System controllers and expansion units, supporting both insertion loss and return loss measurements in automated and manual test workflows.
