This product is Guaranteed 100% Compatible with the Manufacturer Original. The Cisco 10GBASE-LRM Module supports link lengths of 220m on standard Fiber Distributed Data Interface (FDDI) grade multimode fiber (MMF). To ensure that specifications are met over FDDI-grade OM1 and OM2 fibers the transmitter should be coupled through a mode conditioning patch cord. No mode conditioning patch cord is required for applications over OM3. Supports optical fiber cable for durable performance minimal signal loss and fast data transfers to greater distancesWith its thicker diameter to carry the light of multiple wavelengths multi-mode fiber optic cable supports the high bandwidth to carry more information with greater fidelityEnjoy flexibility and scalability with data transfer rate of up to 10 Gbps with 10 Gigabit Ethernet technologyWith 10GBase-LRM technology enjoy up to 10Gbps data transfer rate over optical fiber cable
