SFP-10G-LR Cisco Compatible 10G SFP LR 10km SMF Transceiver

The SFP-10G-LR runs 10G over single-mode fiber to 10km in the SFP+ form factor, standing in directly for Cisco's part of the same coding. Centered at 1310nm and terminated with a duplex LC, it comes up on Cisco platforms as a recognized optic — no service unsupported-transceiver, no console work. DDM/DOM is on board for live monitoring of optical levels once the span is lit.

• Form Factor: SFP+
• Data Rate: 10G
• Protocol: LR
• Wavelength: 1310nm
• Fiber Type: SMF
• Reach: 10km
• Connector: Duplex LC
• DDM/DOM: Yes
• OEM Equivalent: SFP-10G-LR

SFP-10G-LR vs SFP-10G-LR-S: same optics, same reach. The non-S part is Cisco's full-featured coding — accepted across enterprise, service-provider, and transport platforms, including line cards that reject the S-Class part. If your compatibility matrix lists SFP-10G-LR, this is the one to order. For enterprise and data-centre switching only, see SFP-10G-LR-S-TFO.

A 10km budget covers the middle ground of real networks: riser-to-riser links, campus buildings joined over dark pairs, metro access spans that outrun multimode. Built against the relevant MSA and checked one-by-one for diagnostics and link behavior before it leaves the bench. It is backed by TenFourOptics' GreenLights4Life® Limited Lifetime Replacement Warranty.
