The SFP CHECK connects to a standard PC/laptop via a USB cable and uses the default web browser to display SFP details like wavelength, description, range, manufacturer, etc. All the information you need to determine which SFP is the right one for your application.
When used with SFPs that support digital diagnostics (SFF-8472), the SFP CHECK displays the SFP's measurements of transmit and receive signal levels and laser bias current.
