Mode Conditioning Patchcord
BRIEF INTRODUCTION
Mode Conditioning Patchcord (MCP), also known as Gigabit Launch Patchcord, is used inlongwave/long haul (LX/LH) Gigabit Interface Converter (GBICs) with multi mode fiber. Without using MCP, multiple signals are generated when a singlemode laser launch into the center of a multi mode fiber. This would result in pulse broadening or Differential Model Delay (DMD) effects which degrade the modal bandwidth of fiber cable and limit the link span (the distance between the transmitter and receiver) for operating Gigabit application. MCP provides an offset singlemode to multi mode fiber connector point that eliminates the effect of DMD by launching the singlemode laser into multi mode core at a specified offset.

50um and 62.5um multi mode cable are available.
APPLICATIONS
Long Haul to Short Haul LX Gigibit System
Recommended for multi mode cable runs
Gigabit Ethernet 1000Base-LX (1300nm long wavelength)
