Injecting a signal from a laser device into the core of a multimode optical fiber generates a large amount of unwanted signals, as they propagate through various modes. This causes pulse dispersion (DMD), which reduces the usable bandwidth of the fiber optic cable, thus limiting the Gigabit link length (the effective distance between the transmitter and receiver).
MCP patch cords, through an internal interconnection of the appropriate multimode and single-mode fibers, provide correct injection of the single-mode signal into the multimode fiber connector to eliminate the harmful effects of DMD.
These MCP models, also known as Gigabit launch patch cords, have been assembled in accordance with IEEE 802.3z and offer low insertion loss (less than 0.4 dB) and the possibility of supplying 50/125 and 62.5/125 optical fiber for use in Gigabit LX links over multimode.
