Mode Conditioning Patchcord
The Mode Conditioning Patch Cord is designed for long wave multimode applications of Gigabit Ethermet. It is compliant with this IEEE 802.3z application standard. This patch code consists of duplex SC connectors on each end of a cable assembly with a single-mode fiber offset to a multimode fiber connection point in between. The need for this patch cord is due to the single-mode launch nature of the longwave(1300nm) transceiver modules used for Gigabyte Ethrnet. These modules have to operate for both single-mode and multimode fibers. Launching a single-mode laser into the center of a multinmode fiber can cause multiole signals, caused by Differential Mode Delay (DMD) effects, severely limit the cable distance lengths for operating Gigabit Ethernet. A mode conditioning patch cord elminates these multiple signals by allowing the single-mode launch to be offset away from the center of a multimode fiber.This offset opint creates a launch that is similar to typical multimode LED launches.
