Brief Introduction
Mode Conditioning patch cord (also called Gigabit Launch cables) are designed for Gigabit Ethernet 1000Base-LX network and other applications where both dingle-mode and multi-mode interconnects needed. As Gigabit-LX can use both single-mode and multi-mode cables, when a Gigabit-LX transceiver is operated with single-mode cable and directly coupled to Multi-mode cables, an effect known as Differential Mode Delay(DMD) might occur. DMD limit the cable distance lengths for operating Gigabit Ethernet. Mode conditioning cable can enable a single-mode signal to be correctly send through a multimode network...
