Theory of Operation
80C08B Optical Sampling
Module
The 80C08B 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 >9.5 GHz.
10.0 GHz: No fi lter is used and the sampler bandwidth is adjusted; the O/E
bandwidth is adjusted and dominates the response (9.953/10.3125 Gb/s
Multi-rate).
Clock recovery options are available (9.953/10.3125/10.51875 Gb/s
Multi-rate).
80C08C Optical Sampling
Module
The 80C08C 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.
10.0 GHz: No fi lter is used and the sampler bandwidth is adjusted;
the O/E bandwidth is adjusted and dominates the response
(9.953/10.3125/10.518/10.66/10.709/11.1/11.317 Gb/s).
Clock recovery options are available (9.953/10.3125/10.518 Gb/s and
Continuous-rate from 9.8 Gb/s to 12.6 Gb/s).
80C09 Optical Sampling
Module
The 80C09 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 >30 GHz.
Supported standards or data fi ltering rates include OC-192 and FEC10.709.
Clock recovery options are available (OC-192 and FEC10.709).
80C10 Optical Sampling
Module
The 80C10 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 fi ltering 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.
There is no clock recovery option available.
