With ST to ST termination, this high quality fiber optic patch cable is specifically designed for Fast Ethernet, fiber channel, ATM and Gigabit Ethernet applications. 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 molding process provides each connection greater durability in resisting pulls, strains and impacts from cabling installs.Each cable is 100% optically inspected and tested for insertion loss before you receive it.
