Chapter 8 deals with pulse amplitude modulation
through bandlimited additive white Gaussian noise channels.
This contract is composed of a Firm Benefit and an Optional Benefit n 1 detailed infra: - Firm service: provision of a test equipment called Bit Error Rate (BER) tester or binary error rate tester capable of generating signals called Pulse Amplitude Modulation
with 4 levels "PAM4" and conventional signals NRZ, - Optional service n 1: additional functionality described in paragraph 2 of the specifications for this equipment.
Based on its own Forward Error Correction (FEC) and Physical Coding Sublayer (PCS), Ixia will showcase (at booth 4Y17) 400 GbE technology via eight Pulse Amplitude Modulation
(PAM4) electrical lanes, defined as 400GAUI-8 by IEEE802.3bs, using direct attached copper cables, including:
With the goal of combining signal integrity with the challenges of higher speeds, Pulse Amplitude Modulation
(PAM) is being adopted as an alternative to increasing the symbol rates of the conventional NRZ technology, thereby increasing transfer capacity without raising symbol rates.
