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 80C14 Series Optical Sampling Module is a high-performance optical module
that supports high bandwidth telecom and datacom standards, including 16 GFC
Fibre Channel and 14.063 Gb/s Infiniband.
The 80C14 supports the following standards and data filtering rates: 8GFC
(8.500 Gb/s), OC-192/STM-64 (9.953 Gb/s), 10GBase-W (9.953 Gb/s),
10GBase-R (10.31 Gb/s), 40GBase-R4 (10.31 Gb/s), 100GBase-SR10
(10.31 Gb/s), 10GFC (10.52 Gb/s), ITU-T G.975 FEC (10.664 Gb/s), ITU-T
G.709 (10.709 Gb/s), 10 GbE FEC (11.1 Gb/s), 10GFC FEC (11.3 Gb/s),
Super FEC (12.5 Gb/s), 16GFC (14.025 Gb/s), 14G Infiniband FDR
(14.0625 Gb/s).
Clock recovery is supported with the use of the CR175A or CR286A Clock
Recovery instrument (purchased separately).
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.
Supported standards or data filtering rates include 25.781 Gb/s 100GBase-xR4
and 27.739 Gb/s 100GBase-xR4 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.
There is no clock recovery option available.
The 80A01 module is designed to increase the sensitivity of the prescale trigger
input of the DSA8300 to ≤200 mV
The major function block of the module is a high sensitivity, high gain RF
amplifier. The input and output to this amplifier are routed to two identical SMA,
female connectors, labeled Input and Output at the module front panel.
The module receives power from the main instrument through a single connector
at the rear of the module. The power LED indicates the module is receiving power
through the interface connector.
