Description
The AddOn QSFP112-400GB-SR4-AO is an industry-standard, MSA-compliant, and TAA-compliant 400GBase-SR4 QSFP112 transceiver designed for high-performance data center and enterprise networks. Operating over multimode fiber (MMF) with an MPO-12 APC connector, it delivers up to 400Gbps throughput across distances of up to 100 meters using a wavelength of 850nm.
Built with 4x100G PAM4 retimed 400GAUI-4 electrical interface and compliant with IEEE 802.3db and IEEE 802.3ck, this module ensures seamless interoperability and reliable performance. It features hot-pluggable QSFP112 form factor, CMIS 5.0 management, and supports Digital Optical Monitoring (DOM) for real-time diagnostics. Each transceiver is programmed, uniquely serialized, and tested for 100% compatibility, guaranteeing worry-free deployment.
AddOn’s commitment to quality is backed by rigorous testing and a limited lifetime warranty, making this transceiver a cost-effective and dependable solution for scaling high-speed Ethernet networks.
