Serving the rapid growth of Ethernet services by communication Carriers and Service Providers, Exar's Ethernet over PDH (EoPDH), Ethernet over SONET (EoS) and Ethernet over OTN (EoOTN) products provide the most integrated Carrier Ethernet solutions from 1.5Mb/s to 10Gb/s.
Suitable for a wide range of transport platforms from Customer Premise Equipment (CPE) to Add Drop Multiplexers (ADMs), Multi Service Provisioning Platforms (MSPP) and Multi Service Transport Platforms (MSTP). In addition to complex, multiprotocol solutions, EXAR also offers cost, space and power optimized solutions for Media and Protocol conversion.
Flexible Architecture Support
Ethernet transport in carrier's SONET/SDH and PDH networks involves many types of equipment each with their own physical and functional characteristics. All of EXAR's Carrier Ethernet Transport products support GFP or HDLC encapsulation, Virtual Concatenation (VCAT) of PDH links or High and Low Order SONET/SDH paths, and Link Capacity Adjustment Scheme (LCAS) for member failure protection and group bandwidth management. Along with these common features, different products support various client ports, channel counts, network interfaces and network protection architectures enabling optimum suitability for all applications.
Client Interfaces
All Ethernet transport products feature E/FE and GE xMII interfaces for direct connection to external PHYs along with integrated Ethernet MACs for frame delineation and statistics gathering. Higher channel count products also have a channelized SPI-3 packet interface for increased density and generic packet protocol support. In addition to data clients, EXAR's Multi-service products enable the evolution from PDH to Ethernet services by including both types of clients simultaneously. These products have integrated T1/E1 and T3/E3 ports.
Network Protection
Standard SONET/SDH and PDH protection mechanisms are supported by the complete line of EXAR transport solutions. Multiple network interfaces enable linear or ring 1+1, 1:1 or 0:2 operation. Additionally, integrated LCAS allows for VCAT member failure protection and restoration.
Standards Based
Standards based operation is a requirement for complex carrier equipment solutions such as EoS and EoPDH. EXAR's product line is verified to comply with all appropriate Telecordia and ITU Recommendations.
Software Support
These complex, high integration devices demand a complete and robust device management software solution. A complete set of API (Application Programming Interface) calls enable provisioning, monitoring and management of mapped and switched services. Being more than just device drivers, the provided device management software substantially decreases time and effort spent on design, integration and verification of these devices into carrier class network elements.
Applications of Carrier Ethernet Transport products
Exar's world-class EoS and EoPDH solutions are ideal for a wide variety of markets and applications:
- Small form factor Media/Protocol Converters
- Micro Multi-Service Provisioning Platforms (uMSPP)
- ADM/MSPP Service or cards
- Access Concentrators
- ROADMs
