10GBASE-LR operates at a nominal wavelength of 1310 nm over single-mode fiber (SMF, 9/125 µm, G. 652 compliant), providing a standardized maximum link distance of 10 kilometers. There are three wavelength windows for 10G optical module communication applications, namely the 850nm window, 1310nm window, and 1550nm window. It is typically implemented using SFP+ transceivers and defined under IEEE 802. This LC transceiver delivers effortless 10km connectivity for data centers and servers. SPEED REDEFINED: 10 Gigabit Performance for Modern Networks Subheading Focus: Bandwidth & Low Latency Speed defines. Use Dense Wavelength-Division Multiplexing (DWDM) SFP+ modules to integrate WDM transport directly into your Cisco 10 Gigabit Ethernet switches and routers. They. The available optical SFP modules are generally divided into the following categories: 850nm in wavelength/300m transmission distance MMF (SR), 1310nm in wavelength/10km transmission distance SMF (LR), ER at 1550 nm wavelength/40 km distance, ZR at 80 km distance, EX or EZX at 120 km distance, and. FS 10GbE SFP+ module solutions provide a wide variety of 10 Gigabit Ethernet connectivity options for data centers, enterprise wiring closets, Internet Service Providers (ISPs) applications.
