The EKI-1751-AE is a long reach Ethernet extender that utilizes existing copper cabling infrastructure (twisted pair) to extend Ethernet to up to 1200 m over VDSL2. Applications such as IP-based Internet, video surveillance, and voice services can benefit from the EKI-1751-AE series. The devices support VDSL2 Profiles 17a and 30a. The EKI-1751-AE is designed to work in pairs over twisted a pair connection; as an unmanaged product, it is easy to install and each extender can be set to a master (CO) or remote (CPE) mode via a dip switch. Offering one model that can be set to master or remote mode and operate as a pair reduces investment costs while minimizing inventory. The extenders support SNR margin, VDSL2 Profile 30a (high-bandwidth mode) or VDSL2 Profile 17a (long reach mode), and symmetric/asymmetric data throughput, all of which are dip switch-selectable. The selection of symmetrical/asymmetrical throughput of upstream/downstream data rates directly influences the distance covered. LEDs include link activity, VDSL status, and central office or customer premises equipment designation. The extenders meet IEEE 802.3 Ethernet standards and offer transparent support IEEE 802.1Q for VLAN.
