The 80km figure places this part at the far end of the 10G reach ladder, and the 1550nm transmitter over SMF is what carries it there. It is built to the SFP+ MSA so it seats, powers, and manages exactly as the standard prescribes, and each unit is proven against Cisco hosts before release. Backed by the GreenLights4Life® Limited Lifetime Replacement Warranty. In-stock items ship same or next business day — contact 10.4@tenfouroptics.com to confirm availability and lead time.
