The 80C11B module is a long wavelength (1100 to 1650nm) multirate optical sampling module optimized for testing 10 Gb/s datacom and telecom standard rates at 9.953, 10.3125, 10.51875, 10.664, 10.709, 11.0957, 11.317, 12.50, and 14.025Gb/s. With its high optical bandwidth of up to 30GHz (typical) it is well suited for general-purpose high-performance 10Gb/s optical component testing.

The 80C11B can be optionally configured with clock recovery options that can support any standard or user-defined rate in the continuous range from 9.8 to 12.6Gb/s.
