New Coherent FTL410QE3C Four-channel full-duplex QSFP+ optical transceiver Key specifications - Data rate: 2.4x10Gb/s data rate (41.2Gb/s aggregate data rate) - Applications: 40GBASE-SR4 40G Ethernet; 10GBASE-SR 10G Ethernet - Reach on multimode fiber: 100 m on OM3 MMF; 150 m on OM4 MMF Why you need it - Supports both 40G and 10G Ethernet in a single device, enabling flexible upgrade paths without changing fiber infrastructure. - Four independent channels in a compact QSFP+ package provide high port density for scalable data center or campus deployments. - Compatible with standard multimode fiber installations, leveraging common OM3 and OM4 fiber assets. Practical benefits - Simplifies migration from 10G to 40G by offering dual-speed operation in one transceiver - Improves uplink capacity in data center fabric while preserving existing MMF plant - Delivers reliable performance for midrange to high-density networks with established OM3/OM4 fiber Use scenarios - Data center core-to-aggregation links requiring 40G throughput between switches - Upgrading mixed 10G/40G networks: deploy 40G SR4 while continuing to support existing 10G SR links on the same fiber plant - Campus backbone or inter-building links using OM4 fiber to reach up to 150 m (or OM3 up to 100 m) between network devices
