With SC to ST termination, this high-quality fiber optic patch cable is specifically designed for fast ethernet, ATM and gigabit ethernet applications. The small LC connectors satisfy the need for higher port density both in the telecom room and the work area, and offer twice the port density of traditional SC and ST fiber connectors. The LC connector with its RJ-style latch clip design is easy to engage and disengage, and gives each connection greater durability in resisting pulls, strains, snags, and impacts during cabling installs and maintenance. The ST connector features a bayonet locking system.
