PRODUCT PRESENTATION

The PHILISUN 800G QSFP-DD AEC (Active Electrical Cable) is a high-speed copper cable with retimer chips on both ends, ensuring signal integrity for 800G Ethernet. It addresses signal loss issues in PAM4 transmission.Compared with passive cables, 800G AEC supports up to 5 meters with low signal attenuation. It provides a QSFP-DD direct-attach solution and complies with QSFP-DD MSA, IEEE 802.3ck and CMIS 5.0. Easy to install, high-speed and cost-effective, it is ideal for short-range connections within or between adjacent racks in data centers.
