Receiver sensitivity is informative. Stressed receiver sensitivi ty shall be measured with conformance test signal for BER =1x 10 -12 . Note2. Vertical eye closure penalty and stressed eye jitter are th e test conditions for measuring stressed receiver sensitivi ty. They are not the required characteristic of the receiver .
