Broadcom's release of the Tomahawk 5 switching chip, capable of 51.2Tbps, has driven significant advancements in high-speed optical modules. This technological breakthrough has led to the mass production of 800G optical modules, signaling the maturity of the technology in this sector.

Among the various 800G product solutions, the 800G DR8 and 800G 2*FR4 have gained popularity among cloud computing providers due to their seamless compatibility with existing 400G modules. These solutions are now considered mainstream options for widespread adoption.

As a leading provider of comprehensive optical network solutions, 3Coptics offers the 800G OSFP 2xFR4 optical module, which supports transmission distances of up to 2km using two duplex LC single-mode fibers (SMFs). This module converts 8-channel 106.25Gb/s PAM4 electrical signals into 8-channel 106.25Gb/s optical signals, making it ideal for 800G Ethernet, high-performance data centers, and cloud networks. It supports both 800G and 2x400G applications.

The 3Coptics 800G OSFP 2xFR4 optical module primarily supports two application scenarios within spine-leaf network architectures:
