Which devices take the 10G-XFP-LR? Extreme's installation guide lists the 10G-XFP-LR among the optics for devices with up to two 10 GbE XFP ports. In that guide those are the CES 2000 and CER 2000 Series models, such as the 2048CX and 2048FX, which have two 10G XFP uplink ports, and the 2024 models, which take an optional two-port 10 GbE XFP module. What wavelength, reach and fiber does the 10G-XFP-LR use? Extreme describes it as a 1310 nm serial pluggable XFP optic for up to 10 km over single-mode fiber. In the same table the 10G-XFP-SR is 850 nm with a 300 m target range over multi-mode fiber, the 10G-XFP-ER is 1550 nm for up to 40 km and the 10G-XFP-ZR is 1550 nm for up to 80 km, both over single-mode fiber. Can the 10G-XFP-LR go in an SFP+ port? No, it is an XFP module. Extreme's guide lists the XFP optics, the 10G-XFP-LR among them, for devices with up to two 10 GbE XFP ports, and lists separate 10G-SFPlus parts, such as the 10G-SFPlus-SR and 10G-SFPlus-LR, for devices with up to four 10 GbE SFP+ ports.
