Description
The AddOn QSFP28-128GB-SR4-AO is a high-performance, MSA and TAA compliant multi-rate optical transceiver designed for 100GBase Ethernet, OTU-4, and 128G Fibre Channel applications. Operating over multi-mode fiber (MMF), it delivers reliable data transmission up to 70 m on OM3 or 100 m on OM4 at a wavelength of 850 nm using an MPO connector. Featuring support for aggregate bit rates of 103.1 Gbps and 112.2 Gbps, this hot-pluggable QSFP28 module integrates digital optical monitoring (DOM) for real-time performance insights and ensures seamless interoperability with OEM equipment. With power dissipation under 3.5 W, a 3.3 V power supply, and operating temperatures from 0 °C to 70 °C, it is ideal for high-bandwidth data center, enterprise, and access network environments.
