Access Power Supplies Overview

At Emerson Network Power - Embedded Power, our engineers have been designing and developing power supply products for the access market for over 35 years. Our products have helped pave the way for advancements in numerous access applications, including digital loop carrier (DLC) systems, digital subscriber line access multiplexers (DSLAM/IPDSLAM), cable modem termination systems (CMTS), fiber to the "x" (FTTX) installations, passive optical networks (GPON/GEPON), Ethernet access devices (EAD), backhaul over microwave.

Access solutions used to be referred to as the ‘last-mile bottleneck’, but are now considered by broadband users to be the first mile of differentiation of the operator's offering. Broadband-access capabilities are a prime source of differentiation for the basic fixed and mobile Internet access service, as the ability to add additional broadband enables services such as IPTV, mobile TV and multimedia telephony.

Key Power Supply Requirements Include: wide temperature range, robust design, high system availability and battery management, in some applications, fanless design, ingress protection, remote communications.
