PAM4 is a PAM (Pulse Amplitude Modulation) modulation technique that uses 4 different signal levels for signaling. Each symbol cycle can represent 2 bits of logical information (0, 1, 2, 3), which means four levels in one time unit. Therefore, at the same baud rate, PAM4 spits twice as much as NRZ, with higher transmission efficiency, better anti-jamming capability and lower BER.

The PLR4 uses an MTP-12 connector, and require an APC (Angle polished connector) single-mode 8 fibers MTP-12 trunk cable #68018 or an APC single-mode 8 fibers MTP-4LC harness cable #68048.
