1. Measured at BER 10
-10 and at the connector interface with conditions at EOL with an 8.2±0.1 dB extinction ratio optical source. The receiver shall exhibit a BER slope less
than -0.5 dB per BER decade down to a BER of 10
-14. When using the FSK option, the sensitivity will be degraded by 0.5 dB.
2. Receiver sensitivity is valid for data rates from 45 Mb/s to 2.7 Gb/s. For data rates from 45 Mb/s up to 155 Mb/s the PRBS pattern is 2
7 -1, and for data rates from 155 Mb/s
to 2.7 Gb/s the PRBS pattern is 2
23 -1.
3. Measured at BER 10
-12, OSNR 0.1 nm = 19 dB through 0.8 nm optical filter (square shape equivalent filter) and STM-16 PRBS 223 - 1 signal with a CDR (ITU-T G.958)
and an MSA transmitter with 3200 ps/nm optical path. DTV (pin 13) set to Voptimum.
