Supported standards or data filtering rates include
9.953/10.31/10.518/10.66/10.71/11.1 Gb/s.
1
Clock recovery options are available (9.953/10.66/10.71 Gb/s and Continu-
ous-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 1.0625Gb/s
FibreChannel, 2FC (FC2125) for 2.125Gb/s FibreChannel, 10GBase-X4 for
3.125Gb/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--10Gb/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), 8G FibreChannel (8.5 Gb/s), 10G FibreChannel FEC
(11.317 Gb/s). These filter settings require no hardware filters.

An electrical clock recovery output signal is provided that can be routed to
the Tektronix 80A05 or 80A07 for clock recovery.
The 80C25GBE 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 >65 GHz.
1
Supported standards or data filtering rates include 25.781 Gb/s 100GBase-
LR4 and 100GBase-ER4, and 27.739 Gb/s 100GBase-LR4 with FEC and
100GBase-ER4 with FEC.

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.

Option CRTP provides electrical signal outputs for use with the Tektronix
CR286A Option HS clock recovery instrument, or other compatible clock
recovery devices.
