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 Duplex fibers, the transmitter should be coupled through a mode conditioning patch cord. No mode conditioning patch cord is required for applications over OM3 or OM4. The Cisco 10GBASE-LRM Module also supports link lengths of 300m on standard single-mode fiber (SMF, G.652).Here I would like to introduce one of small but very important accessory in the fiber cabling field, the fiber optic adapter. The fiber optic adapters are commonly used in the fiber optic connection field.
They are used to provide a cable to cable or cable to equipment fiber optic connection. Through some many years of develop, now these fiber optic adapters have many different shapes but still all serve the same purpose, it allows the OM2 Duplex optical fiber cables to be connected to each other singly or in a large network which allowing many devices to communicate at once. While in this two types of using, the use of simply to connect two fiber optic cables to one another is the most common uses. By connecting two cables together can allow two devices to communicate from a distance through a direct connection with the fiber-optic line.
