This is a 4m ST (male) to LC (male) orange duplex fiber patch cable. OM2 cables have a standard jacket color of orange and a core size of 50m. They support 10 Gigabit Ethernet for lengths measuring up to 82 meters, but are more commonly used for 1 Gigabit Ethernet applications. This jacketed cable is best suited for LANs or SANs, and is recommended for connection between fiber patch panels, hubs, switches, media converters and routers. 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.This is a 4m ST (male) to LC (male) orange duplex fiber patch cable.
