Fiber is currently reported to connect 15-20 percent of businesses in metro area networks (MANs). Locations with fiber connectivity typically have complex bandwidth and application requirements that go beyond what best effort Ethernet services can offer. For this reason, carriers will usually deploy an Ethernet demarcation device at the customer premises to enable end-to-end performance monitoring and management capabilities, ensuring five nines (99.999%) reliability and service resiliency.
Delivering advanced Ethernet over fiber solutions, RAD’s ETX Fast Ethernet and Gigabit Ethernet demarcation devices have been designed with Carrier Ethernet attributes, allowing complete network visibility up to subscriber endpoints, regardless of the various protocols involved in the traffic path, the underlying networks or number of operators who own them. Extensive Ethernet OAM (Operation Administration and Maintenance) diagnostics enable remote and automatic fault localization without service interruptions or costly on-site inspections. Moreover, incremental bandwidth provisioning, delivering access rates of up to 100 and 1,000 Mbps, as well as rate limitation and traffic classification and prioritization per port, per flow and per class of service (CoS), assist carriers in addressing diverse client needs and offering binding SLAs (Service Level Agreements) with uniform QoS (Quality of Service). Support for VLAN tagging and stacking (Q-in-Q), as well as for EPL (Ethernet Private Line) and EVPL (Ethernet Virtual Private Line) services, allow transparent delivery of traffic and consistent, LAN-like user experience across wide area networks (WANs).
In addition to these advanced capabilities, the ETX intelligent NTUs enable seamless transport of Ethernet traffic over different media by linking copper cabling with fiber optics and multimode with single-mode fiber cables.
Complying with the latest industry standards, the ETX Ethernet over fiber solutions provide carriers, operators and service providers with sophisticated tools to capitalize on new opportunities and maintain business effectiveness.
