fiber optic patch cord name
MCP SC PC to SC UPC duplex 62.5/125 fiber optic mode conditioning patch cord 3meter
How the Mode Conditioning Cable Works
The need for this conditioning fiber optic patch cord is due to the single-mode launch nature of the-LX or long-wave(1300nm) transceiver modules used for Gigabit Ethernet.
Launching a single-mode laser into the center of a multimode fiber can cause multiple signals to be generated that confuse the receiver at the other end of the fiber.
In that case, a mode conditioning patch cord eliminates these multiple signals by allowing the single-mode 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. (see diagram below)
