Product OverviewGenuine Nokia 474899A.101 AOMB ALPHA QSFP+ Multimode Transceiver, OEM Finisar FTL410QD4N-NS, fully tested and 100% working guaranteed. This is a high-performance 40G SR4 / 4x10G breakout dual-mode module, specially optimized for Nokia AOMB ALPHA platform and modern data center short-reach high-density interconnection.Operating at 850nm VCSEL wavelength over OM3/OM4 multimode fiber, it supports 300m transmission on OM3 and 400m on OM4. The unique breakout function allows one 40G QSFP+ port to split into four independent 10G SFP+ channels, providing flexible and cost-effective 10G/40G mixed networking solutions. Built with low-power four-channel parallel VCSEL array, ultra-low BER and excellent stability for 24/7 continuous operation. Equipped with DDM real-time monitoring and hot-plug capability, zero downtime for upgrade and replacement. Perfect plug-and-play compatibility with Nokia AOMB ALPHA units and mainstream data center switches.Core Key Selling Points
