The LightWave Mode Conditionig LC-LC Multimode OM1/Singlemode OS2 Fiber Optic Patch Cable is a Optical Mode Conditioning cable that incorporates Multimode 62.5/125 and Singlemode 9/125 glass to allow a Singlemode Transiever to communicate to a Multimode Tranceiver. This allows a reliable means of connecting an internal multimode fiber network with external singlemode 1000Base- LX based transmission. Mode conditioners provide a method of offsetting a single-mode fiber core with a corresponding multimode fiber. This calibrated offset reduces a phenomena called differential mode dispersion, or DMD, which can cause the transmitting laser pulse to spread out and merge into neighboring pulses creating bit errors in the transmission signal.
