EFM-10/20/40 LAN Extender

EFM-10-20-40 Lan Extender

EFM-X0 is an Ethernet Network Extender designed to provide bonded high-speed Ethernet First Mile services over SHDSL on existing copper infrastructure. It is a bridge mode modem that delivers Ethernet services with symmetrical bandwidth at rates up to 22.8 Mbps (4 Pairs, Standard mode with TC-PAM 32) and 45.3 Mbps (4Pairs, Enhanced mode with TC-PAM 64). Implemented based on IEEE 802.3ah EFM standards for advanced performance and management features, EFM-X0 ensures high reliability, low expense and maximum throughput. The introduction of EFM copper bonding technology allows delivery of higher bandwidth to longer distances over multiple copper pairs, enabling a good alternative in place where fibre is not economical to deploy. This Ethernet-pure solution provides a seamless integration into today and tomorrows networks. EFM-X0 extends the reach of Ethernet services to the sites by using bonded copper pairs. Up to 4 pairs can be bonded together for aggregated bandwidth over 45Mbps (Enhanced mode with TC-PAM 64 line coding technology). Designed with standard-based EFM technology (2BASE-TL), deployment of Ethernet services with EFM-X0 is quick and simple on the existing copper plant. It operates mainly in Point-to-Point connection between remote office and enterprise headquarters, providing symmetrical high-speed connectivity that is ideal for large and small-to-medium enterprises to deliver business-class Ethernet service.
