The 828 Optical Wavelength meter has a speed measurement rate as high as 1 kHz. WDM components are more efficiently tested, and time resolution is much higher for a more detailed wavelength characterization. The 828B includes a SCPI interface via USB, Ethernet, or GPIB cable. With a rugged design, this device is perfect for manufacturing environments. For more specifications on the 828 optical wavelength meter, download the datasheet.
