Overview
The VIAVI SmartClass OBS-550 is a battery-operated, handheld optical broadband light source for fiber characterization. It combines test sources for polarization mode dispersion (PMD), chromatic dispersion (CD) and attenuation profile (AP) measurements in one rugged, splash-proofed field unit with a single optical port.
Used together with the VIAVI Optical Dispersion Measurement (ODM) modules (8100 Series), the OBS-550 enables CD, PMD and AP measurements on fiber networks including CWDM/DWDM systems and high-speed links. It covers the S, C and L bands from 1460 to 1640 nm.
The OBS-550 is the high-output-power version of the SmartClass OBS-500/550 family. In addition to the broadband mode, it provides a high-power mode intended for testing non-amplified links of up to 300 km for PMD and 260 km for CD. Testing through in-line amplifiers/EDFAs is also supported.
The operating mode and application (PMD, CD or AP) are selected on the unit and indicated by LEDs. The optical interface uses an interchangeable adapter system, and the instrument runs on AA cells or from an external AC adapter.
