SmartClass OBS 500/550 Optical Broadband Light Sources

product

High Performance Light Source for PMD, CD and Attenuation Profile (AP) Measurements

10 GE /40 GE service delivery and 40G /100G network deployments or upgrades are driving fiber characterization test out to field tech support groups. Cost effective solution and fast return on investment are required due to wider test set dispatch.

The growing number of projects is driving an increasing demand for higher productivity with better reliability and availability.

The OBS-500/550 combines three applications in one rugged and splash-proofed field solution. Its high output power (OBS-550) and wide wavelength range enable the characterization of any fiber network configuration. In combination with the Viavi Optical Dispersion Modules (ODM) (MRDISPAP & DISPAP modules for T-BERD/MTS-6000A and – 8000 platforms), high performance CD, PMD and AP measurements can be executed.

Key Benefits

Cost-effective solution, designed for high-performance testing
SmartClass design for harsh environmental conditions
Battery-operated, portable field handheld
High dynamic range for ultra-long haul PMD and CD testing
Compatible with Viavi MRDISPAP and DISPAP modules for PMD, CD and AP Measurements
Covers the SCL bands (1460 – 1640nm)
OBS-550 version features a high-dynamic mode to test non amplified links of up to 300km for PMD and 260km for CD (in combination with DISPAP module)
Both versions allow testing through in-line amplifiers/EDFAs
