Replacing a failed unit with the ONS-SC+-10G-59.7 preserves the span as engineered: the same 1559.79nm DWDM wavelength, the same 80km reach rating, the same SFP+ slot on the Cisco platform. It carries OC-192 or 10GBASE traffic over single-mode fiber with LC/UPC termination and is rated for 0 to 70°C operation, so the original design assumptions keep holding after the swap.

Tested & Proven: Every TenFour Optics part is coded, tested, and verified before shipment — see Tested & Proven.
Because the wavelength matches the plan, no coordination with the far end or the mux is needed beyond the physical change itself. The part is produced to MSA requirements and audited against them before dispatch. the GreenLights4Life® Limited Lifetime Replacement Warranty is attached to every unit. In-stock items ship same or next business day — contact 10.4@tenfouroptics.com to confirm availability and lead time.
