The Signamax 065-79LXEWDMx1490 models are Small Form-factor Pluggable (SFP) multimode fiber modules that support Gigabit Ethernet or SONET OC-12 over a single strand of singlemode fiber cable at distances up to 20 kilometers. There are two models in this series: one transmits at 1310 nm and receives at 1490 nm (model 065-79LXEWDMA1490), and the other transmits at 1490 nm and receives at 1310 nm (model 065-79LXEWDMB1490). These modules are designed to be used in pairs facing each other across a single stand of singlemode fiber. They are a cost-effective method of providing changeable Gigabit Ethernet or SONET OC-12 single-fiber singlemode interfaces to switches and media converters equipped with a standard SFP port.

** Maximum distances attainable on singlemode fiber circuits are dependent upon a circuit’s conditions; i.e., the number of splices and patch panels and the number of bends in the circuit path. For comparison with competing products, please use the Link Power Budget for meaningful comparisons.
