Description
Overview
The EXFO OSA20-58 is the fastest diffraction-grating-based optical spectrum analyzer, offering state-of-the-art performance for research, development, and manufacturing of high-end optical products. Operating from 1250 to 1700 nm with wavelength accuracy of ±10 pm (1500–1640 nm range) and ±25 pm across the full band, the OSA20 combines lab-grade optical performance with an intuitive 12-inch multitouch interface for real-time signal analysis and characterization.
Key Features

Specifications
| Accurate | The OSA20’s monochromator is built around EXFO’s renowned filter technology. Its narrow bandwidth (20 pm) is maintained throughout the spectral range of operation (1250 – 1700 nm). The monochromator also stands out by its extremely sharp filter edges and low stray light, ideal for optical signal to noise ratio (OSNR) measurement of tightly packed WDM channel testing. The OSA20 has a best-in-class wavelength repeatability of ±2 pm and accuracy of ±10 pm specified over 1500-1640 nm and comes with its own built-in wavelength calibration source. |
| Fast | The OSA20 is the fastest optical spectrum analyzer of its kind with a maximum sweep speed of 2000 nm/s and a fixed sampling resolution of 2 pm for all scans. This means every measurement is taken at the highest resolution and the highest accuracy. Sweep speed is determined solely by the choice of the sensitivity level: -55 dBm at 2000 nm/s down to -90 dBm by averaging over 380 scans with HIGH at 0.5 nm/s. With a sweep rate of about 3 scans per seconds covering the C+L band (at -60 dBm sensitivity), the OSA20 is the ideal tool for quick and precise optical alignment followed by high resolution characterization. |
| Easy to Use | The OSA20 brings optical spectral testing into the 21st century with a 12-inch capacitive multitouch screen, an industry first and its intuitive graphical user interface (GUI) for fast navigation and scrolling through single setup menus. With pinch-to-zoom gesture and automated signal search algorithms, getting to the interesting data has never been easier! Keyboard, mouse or hard drive can also be used through the many USB interfaces. And to make sure to get the best measurement, the OSA20 is also fitted with an optical connector plate that can be easily removed to inspect and clean the optical fiber connectors. |
| Efficient Analysis Features | The OSA20 comes with built-in application-oriented analysis adapted to different types of spectrum or acquisition techniques. WDM: wavelength division multiplexing with OSNR tool compatible with 400G+ spectrum. RLT: the recirculating loop transmission mode is a special version of WDM specially designed to be used in a long-distance transmission simulation with an optimized signal acquisition algorithm. SML: singlemode laser characterization of side mode suppression ratio (SMSR), central wavelength and optical power for distributed feedback Bragg laser diodes, tunable lasers or transceivers. OFA: optical fiber amplifier characterization of gain and noise figure for semiconductor, Raman or fiber optical amplifiers. PCT: passive component tester characterization of optical filters, isolators or fibers. This mode can also be used for fast alignment of optical devices. BBS: broadband source characterization of super luminescent or edge-emitting LED. MML: multimode laser characterization of multiple longitudinal model lasers, such as Fabry-Perot laser diodes. OSA: optical spectrum analyzer general operation mode containing most of the analysis tools available on the OSA20 for any signal that does not fit one of the above modes. |
