PRODUCT PRESENTATION
The PHILISUN SFP28(25G) Active Optical Cable is a direct-attach fiber assembly utilizing SFP28 connectors and the Multi-Mode Fiber (MMF) scheme. The product complies with the SFF-8431 MSA standard and is suitable for 25Gbps connections within racks and across adjacent racks. It uses OM3/OM4 Multimode Fiber. Its compact structure and fully sealed integrated optics reduce costs compared to conventional optical modules and jumpers, while significantly improving reliability and reducing maintenance. This AOC guarantees broad compatibility with major vendor platforms including Cisco, H3C, Huawei, Juniper, and Arista, and more.
