Interface type 10GBASE-LRM Central wavelength 1300 nm Fiber grade FDDI-grade OM1 OM2 OM3 Transmission distance < 220 m (721.78 ft) < 220 m (721.78 ft) < 220 m (721.78 ft) < 220 m (721.78 ft)  Single-mode fibers Single-mode fibers (SMFs) have thinner fiber cores and can transmit light in only one mode. Single-mode fibers suffer little intermodal dispersion and are suitable for long-haul communication. Fiber diameter Fiber diameter is expressed as core diameter/cladding diameter, in μm. For example, 9/125 μm means the fiber core diameter is 9 μm and the fiber cladding diameter is 125 μm. For the HP Comware-Based Switches, the following fiber diameters are recommended:  G.652 common single-mode fiber: 9/125 μm  G.655 single-mode fiber: 9/125 μm  Common multimode fiber: 62.5/125 μm  G.651 multimode fiber: 50/125 μm (for multimode VCSEL laser) Connector CAUTION: Cover the connector with a dust cap when it is not connected to any optical fiber. Connectors connect transceiver modules to the corresponding transmission media. The transceiver modules available for the HP Comware-Based Switches use the following types of connectors:  Lucent connector or local connector (LC)  Multi-fiber Push On connector (MPO) Figure 1 LC connector 5
