Optical Component Testing
EXALOS SLEDs, especially in the 1300 nm and 1550 nm wavelengths bands, offer wide optical bandwidths, high polarization extinction ratios, high optical power spectral density which are all important features Optical Network diagnostics.
SLEDs are used in diagnostic test equipment for Optical Networks. Several measurement techniques like Wavelength Drift Monitoring, Chromatic Dispersion (CD) and Polarization Mode Dispersion (PMD) exploit the characteristics of SLEDs, taking advantage of their wide bandwidth, high optical power spectral density, low ripple, high polarization extinction ratio and operating wavelengths which can cover the C and L communication bands.
C omponent testing equipment can benefit from EXALOS’ SLEDs that provide the advantage of stable power and stable center wavelengths over time.
EXALOS SLEDs allow fast optical performance measurements over a wide spectrum of wavelengths (650 to 1700 nm), without the need of expensive tunable lasers. The SLEDs can be used for fiber optic test equipment that enable the measurement of spectral insertion losses and transmission characteristics for Passive Optical Network (PON) components, CWDM or WDM components, fiber Bragg gratings, optical attenuators, photonic switches, broadband couplers, multiplexers, isolators, circulators, hybrid components and depolarizers.
For optical component testing, EXALOS offers a broad variety of high-power and broadband SLEDs in the wavelength range from 1250 to 1650 nm, either as optical modules or as an assembly with a ultra-low-noise and ultra-stable driver board (EBD). Furthermore, EXALOS is offering custom OEM solutions or turn-key benchtop instruments (EBS) of combined broadband sources that are tailored to customer-specific needs, for example with integrated optical filters or optical depolarizers.
