Exfo IQ-2600 Tunable Laser Source

The EXFO IQ-2600 Tunable Laser Source is a optical instrument engineered for precise characterization of fiber-optic components in DWDM systems. It combines continuous wavelength tuning across the C and L bands with stable output power and medium coherence to minimize interference effects during component testing. ## Technical Specifications Wavelength and Tuning • Wavelength range: 1510 nm to 1612 nm (C and L bands) or 1520 nm to 1570 nm for specific modules • Tuning resolution: 0.01 nm • Tuning method: Continuous or step-by-step with programmable sweep functions Optical Output • Output power: Greater than 0 dBm (1515–1610 nm range); typically 5 dBm for IQ-2600-89 module • Power attenuation range: 10 dB • Power stability: ±0.01 dB over one hour; ±0.05 dB over 8 hours (IQ-2600-89) • Signal-to-SSE ratio: Greater than 65 dB (up to 75 dB for some configurations) • Source spontaneous emission suppression: Greater than 60 dB local noise suppression (1515–1610 nm) Spectral Performance • Spectral linewidth (FWHM): Approximately 1 GHz (~0.01 nm); 0.05 nm typical for IQ-2600-89 module • Coherence length: Approximately 10 cm; approximately 15 cm into SMF-28 fiber ## Key Features • Dual operational modes: tunable laser output and ASE (Amplified Spontaneous Emission) source for passive WDM component loss testing • Real-time wavelength monitoring via 5% cavity tap output • TTL triggering (Trig In/Out) for external instrument synchronization • Erbium fiber ring laser architecture • Multiple output connector options: FC, SC, E-2000, FC/APC; PMF option available ## Typical Applications • Fiber-optic component characterization and qualification • DWDM system testing and research • Manufacturing process validation ## Compatibility & Integration The IQ-2600 operates as a standalone benchtop instrument or as a module within the EXFO IQS test platform, compatible with IQ-203 and IQ-206 mainframes. Software control enables manual and programmed wavelength and power management with multiple sweep options.
