Cisco-compatible · SFP-10G-LR20-TFO
The SFP-10G-LR20 is coded for Cisco switching and routing gear. It is a 10G SFP+ built to the LR specification, driving single-mode fiber to an extended 20km over a duplex LC. That 20km reach stretches a standard LR launch to the longer end of its range, which suits the metro and campus hops where a short-reach optic runs out of budget but a full long-haul part is more than the span needs. Optical power and temperature are reported over DDM for link monitoring at the host.
