Mode Conditioning Cable
The QPC Fiber Optic Mode Conditioning Patch Cord is designed for long wave (-LX) multimode applications of Gigabit Ethernet. It is compliant with the IEEE 802.3z application standard. This patch cord consists of duplex SC connectors on each end of a cable assembly with a singlemode fiber offset to a multimode fiber connection point in between. The need for this patch cord is due to the singlemode launch nature of the -LX or long-wave (1300nm) transceiver modules used for Gigabit Ethernet.
These modules have to operate for both singlemode and multimode fibers. Launching a singlemode laser into the center of a multimode fiber can cause multiple signals to be generated that confuse the receiver on the other side 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 cord eliminates these multiple signals by allowing the singlemode launch to be offset away from the center of a multimode fiber. This offset point creates a launch that is similar to typical multimode LED launches.
