OSA 1574nm-1608nm 186THz -190THz *DIS*

Wavelength Range L-Band 1574-1608nm (190.5 THz - 186.3 THz).

The OCC-DWDM Optical Channel Analyzer is the most rugged and affordable full-featured Mini OSA on the market. It is designed for simple operation and is suited for field or lab use. Available in up to 82 channels for C or L bands, with 50 or 100 GHz channel spacing, it displays a full scan twice per second. Offering high-end features such as Power Tilt for channel equalization and Gain Tilt to adjust EDFA gain flatness, it’s a real workhorse.

One-button Auto-Test and a full set of selectable scale limits and thresholds makes zeroing in on channel measurements easy. For flexibility, the channels are selected by either wavelength or frequency and the information is displayed in graph or table mode on a high-brightness color LCD display. The unit allows users to set Pass/Fail thresholds and can store up to 1,000 test results, which that can be downloaded onto a USB flash drive and documented with the included certification software for fast, easy reporting.

The Onboard Help System guides new users through operations and assists in parameter settings. The PRO-DWDM Optical Channel Analyzer is housed in a ruggedized metal enclosure with a robust, protective boot.
