Reference receiver filter options:
The standard N1092 includes filters to test the
following data rates
25.78 Gb/s (25/50/100 Gb Ethernet)
26.56 Gb/s (400 Gb Ethernet)
27.95 Gb/s (OTU4)

100GBASE-SR4 TDEC (12.4 GHz)
20.6 Gb/s
N1092-168
N1092-206
Maximum optical channel –3 dBo bandwidth is 28 GHz, achieved using the 32xFC filter setting.
Measured frequency response data during recertification falls within performance test line
limits with allowance for system-to-system measurement uncertainty.

1. Generally represents the power level where an ideal eye diagram will approach 0% mask margin due to
noise of the oscilloscope. Provides a non-specified figure of merit to compare sensitivities of various optical
channels. These values are calculated from the characteristic noise values.
