With LC to ST termination, this high quality fibre optic patch cable is specifically designed for Fast Ethernet, fibre channel, 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 fibre 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. The Low Smoke Zero Halogen (LSZH / LS0H) jacket is composed from materials that lessen the smoke and halogen emissions when the cable is exposed to extreme temperatures. This reduces the amount of harmful toxic and corrosive gases that cabling made with plastic materials would otherwise emit into the air during combustion. This construction makes LSZH cables ideal for use where the protection of people and equipment from harmful corrosive gases is absolutely critical. The patented injection moulding process provides each connection greater durability in resisting pulls, strains and impacts from cabling installs.
