Overview

The VIAVI optical broadband light sources are part of the VIAVI fiber characterization and dispersion testing solutions. A single unit or module combines test sources for Chromatic Dispersion (CD), Polarization Mode Dispersion (PMD) and Attenuation Profile (AP) measurements, allowing network operators, fiber installers and dark fiber providers to characterize fiber systems including CWDM/DWDM with ROADM and high-speed networks from 10 Gbps to 400G/800G.

The family comprises the SmartClass OBS-500 and OBS-550 battery-operated handheld sources and the Optical Broadband Source (BBS) module E81BBS2A for the OneAdvisor 800 platform. All versions work with the VIAVI Optical Dispersion Measurement (ODM) modules (8100 Series) to perform CD, PMD and AP measurements.

SmartClass OBS-500/550

The OBS-500/550 combines three applications in one rugged, splash-proofed field instrument covering the S, C and L bands. The OBS-550 adds a high-power mode for testing non-amplified links of up to 300 km for PMD and 260 km for CD, and both versions allow testing through in-line amplifiers/EDFAs. The operating mode is selected between high power (OBS-550) and broadband, and the application between PMD, CD and AP.

BBS Module for OneAdvisor 800

The BBS module provides a source for CD (referenced phase shift method), PMD (fixed analyzer method) and AP with in-line isolator over a 1260 to 1640 nm range. It is shock-proof and vibration-proof with no moving parts, and when combined with the ODM module reaches a dynamic range of up to 45 dB. It also supports component testing and can form a remote solution when combined with an OTDR.
