40G Transceivers

40G QSFP+ transceivers bridge the gap between legacy 10G infrastructure and modern 100G+ backbones, commonly deployed in mid-size data centers, metro area networks, and inter-switch links needing more headroom than 10G but not yet requiring 100G. Compliant with IEEE 802.3bm, they support reach options from under 150 meters to 40 kilometers over LC or MPO interfaces. Many enterprises still run 40G in core aggregation layers where a full 100G upgrade isn't yet cost-justified.
