This is a 10m LC (male) to SC (male) orange duplex riser-rated fiber mode conditioning cable. OM1 & OS1 eliminates differential mode delay signals by aligning the single-mode launch away from the center of a multimode fiber core. This creates a transmitted signal that is similar to typical multimode light emitting diode (LED) launches. This optical fiber nonconductive riser (OFNR) cable is best suited for use in interior fiber-optic applications. A duplex cable is a two-strand fiber optic patch cable that works best with transceivers that both transmit and receive. Our patch cables are 100% compliant for all of your networking needs. Our products are guaranteed by federal law to not affect or void OEM warranties.
