Cisco 25GB SFP28 Transceivers - Refurbished, Used, New
This collection carries Cisco 25G SFP28 transceivers, in new and refurbished or used condition. Refurbished and used units are tested before they ship. The modules cover short-reach multimode links, 10 km and 40 km single-mode links, and a single-strand bidirectional option, and several are dual-rate parts that also run at 10G.

Which 25G SFP28 do I need?
Start with the fiber already in place. For multimode runs inside a rack row or server room, the SFP-25G-SR-S covers up to 100 m on OM4. The SFP-10/25G-CSR-S reaches further, up to 400 m on OM4, and also runs at 10G, which helps when one end of the link is still a 10G port. For single-mode runs up to 10 km, the SFP-10/25G-LR-S is the standard choice. The "-I" parts carry Cisco's industrial temperature rating: the SFP-10/25G-LR-I for 10 km, and the SFP-25G-ER-I for links up to 40 km.
Does the host port need FEC?
Often, yes. Cisco states that the SFP-25G-SR-S needs RS-FEC on the host port, and that the SFP-10/25G-LR-S, SFP-10/25G-LR-I, SFP-10/25G-BXD-I and SFP-25G-ER-I need RS-FEC at 25G to reach their full rated distance. Without RS-FEC, Cisco gives shorter reaches for the LR-I and BXD-I. The CSR-S does not need FEC at 10G. Check that the switch port has RS-FEC enabled before you deploy.
How does the BXD-I work?
The SFP-10/25G-BXD-I sends and receives over a single strand of single-mode fiber. Cisco specifies that it always pairs with an SFP-10/25G-BXU-I at the other end of the link, so order the matching module for the far side.
