PAM4 (Pulse Amplitude Modulation 4) is a modulation technique that encodes 2 bits of data per signal pulse, doubling the data rate compared to traditional NRZ (Non-Return-to-Zero) modulation. This transceiver uses PAM4 to achieve 800Gbps throughput over existing optical infrastructure, enabling high speed transmission without requiring wider bandwidth or more complex optics.
The transceiver operates at a wavelength of 1310nm and is optimized for single-mode fiber (SMF).
This 800G 2xDR4 OSFP with 1310nm wavelength is specifically designed for use with singlemode fiber (SMF), as indicated by the 1310nm wavelength and 100m transmission distance specification.
