The 80C12 module is a broad wavelength (700 to 1650 nm), multi-rate optical sampling module providing 1G, 2G, 4G and 8G telecom and datacom testing. This highly flexible module can be configured to support either lower data rate applications (1 to 8 Gb/s) or a wide variety of 10 Gb/s applications. The low data rate applications include: 1, 2, 4 and 8G Fibre Channel and %22by 4%22 wavelength division multiplex standards such as 10GBase-X4 and 4-Lane 10 Gb/s Fibre Channel. The supported 10Gb/s application includes both datacom and telecom application. The supported 10 Gb/s datacom applications include 10 GbE applications at 9.953, 10.3125, 11.0957 Gb/s and 10G Fibre Channel applications at 10.51875 Gb/s and 11.317 Gb/s. The 80C12 also provides telecom rate testing at 9.953, 10.664 and 10.709 Gb/s. With its amplified O/E converter design, this module provides excellent signal-to-noise performance and high optical sensitivity, allowing users to examine low-power level optical signals. Clock recovery for the 80C12 is provided via the 80A05 or 80A07 (sold separately)
