FS.COM supplies standard and customized mode conditioning patch cables (MCP) in 62.5/125 and 50/125 , which are specified for 1000BASE-LX/LH and 10GBASE-LRM transceivers transmitting in the 1300nm window and applicated over multimode plants.
Launching a singlemode laser into the center of a multimode fiber can cause multiple signals to be generated that confuses the receiver at the other end of the fiber. These multiple signals, caused by Differential Mode Delay (DMD) effects, severely limit the cable distance lengths for operating Gigabit Ethernet. A mode conditioning patch cable eliminates these multiple signals by allowing the singlemode launch to be offset away from the center of a multimode fiber.
