The rapid world-wide growth of the internet has prompted the performance improvement and infrastructure expansion of fiber optic communication system. The demand for higher quality and better performance optical communication had led to the continuous increase of deployment of new high speed network. Especially, faster access network service is needed to overcome the bandwidth bottleneck between local access network and long-haul network.

Fast Ethernet, FDDI, and ATM Protocol are the main protocols for the indoor and premises network solution, and Multimode Fiber and UTP Cable are used as main transmission media. In general, the transmission speed of LAN backbone network needs to be 10 times faster than desktop access line, which necessitates the introduction of Gigabit Ethernet system that offers high information carrying capacity. Gigabit Ethernet, being an extended version of Ethernet system, is preferred as the enterprise LAN and needs a new transmission media. LS Cables newl developed Giga is the perfect media for Gigabit Ethernet system.
