Product Overview

Aeon Super AI 1.6T OSFP 2*DR4 PAM4 Optical Transceiver is a 2×800Gb/s Twin-port OSFP module designed for 1.6T InfiniBand and cloud network applications. It supports a maximum fiber reach of 500 meters over 8 single-mode fibers using 200G-PAM4 modulation.

The module uses two 2-fiber, 4-channel MPO-12/APC optical connectors at 800Gb/s each, forming an 8-channel (2×DR4) parallel single-mode data center reach design. Maximum power dissipation is 26W and the module is fully RoHS compliant.

Digital diagnostic monitoring functions are available via the 2-wire serial (I²C) interface as specified by CMIS Rev 5.3.
