Santec has launched the extended-range Swept Photonics Analyzer (SPA-110).
In conjunction with Santec’s tunable laser, the SPA-110 uses optical frequency domain reflectometry (OFDR) technology to analyze compact fiber optic and photonic devices for insertion loss and return loss with a spatial resolution of over 5 µm.
The SPA-110 builds on Santec’s predecessor, the SPA-100, by extending the total measurement range from 5 m to 30 m. This increased range accommodates the addition of optical signal conditioning devices, such as polarization controllers and optical switches, within the fiber optic setup.
What’s compelling about this enhancement is that it makes the system particularly suitable for the more comprehensive characterization of small devices like silicon photonic circuits, fiber optic components, and compact fiber optic assemblies. Also, the extended scan length allows for the analysis of longer fiber optic cable assemblies with closely spaced components, where OTDR technology might struggle to distinguish between them.
Finally, the 80 dB dynamic range during Wavelength-Dependent Loss measurement (WDL) allows for the detection of even weaker reflection events.
