The 80C10B module is designed to test long wavelength (1310 and 1550 nm)
signals. This module is intended to be used as a test and measurement tool for
high bandwidth telecommunications with its high optical bandwidth >80 GHz.
Supported standards or data filtering rates include OC-768 and FEC43.02
(G.709).
30 GHz: The sampler bandwidth and response is set during the calibration
such that the combined system will have an Optical Bandwidth (-6 dB)
>30 GHz.
65 GHz: The sampler bandwidth and response is set during the calibration
such that the combined system will have an Optical Bandwidth (-6 dB)
>65 GHz.
80 GHz: The sampler bandwidth and response is set during the calibration
such that the combined system will have an Optical Bandwidth (-6 dB)
>80 GHz.
There is no clock recovery option available.
The 80C11 module is designed to test long wavelength (1100-1650 nm) signals.
This module is intended to be used as a test and measurement tool for high
bandwidth telecommunications with its high optical bandwidth >20 GHz.
Supported standards or data filtering rates include
9.953/10.31/10.518/10.66/10.71/11.1 Gb/s.
Clock recovery options are available (9.953/10.66/10.71 Gb/s and
Continuous-rate from 9.8 Gb/s to 12.6 Gb/s).
The 80C12 module is designed to test both long and short wavelength
(700-1650 nm) signals. This module is intended to be used as a test and
measurement tool for high bandwidth telecommunications with its high optical
bandwidth >10 GHz.
There are three Reference Receiver filters selectable that are customer
specified from the following list of five rates: 1FC (FC1063) for 1.0625 Gb/s
Fibre Channel, 2FC (FC2125) for 2.125 Gb/s Fibre Channel, 10GBase-X4
for 3.125 Gb/s, VSR-5 for 3.31776 Gb/s, and 4FC (FC4250) for 4.25 Gb/s
Fibre Channel. Filterless, full-bandwidth settings (8.5 GHz and 9 GHz) are
also available.
In addition, this module offers the option to support 10 Gb/s optical standards
as well. This option is mutually exclusive with the sub-10 Gb/s filter options.
The standard reference receiver filter rates offered with the Option 10G are
SONET/SDH OC-192/STM-64, 10GBase-W, 10 Gb Ethernet (9.95338 Gb/s),
10GBase-R (10.3125 Gb/s), 10G Fibre Channel (10.51875 Gb/s), G.975
FEC (10.66 Gb/s), G.709 FEC (10.71 Gb/s), 10GBE FEC (11.0957 Gb/s),
