Carrier Access Solutions
Innovative carrier access platforms and disaggregated open solutions
Accton continuously strives to provide the latest cutting-edge carrier access solutions to its carrier, service provider, and Multiple System Operator (MSO) customers. With more than 32 years of R&D experience in Ethernet hardware and software design, Accton’s engineering teams have a proven track record in supplying cost-effective ODM solutions to Tier-1 vendors worldwide.
Accton’s experience in carrier access products covers a wide range, from passive optical networks for residential broadband access to NEBS-compliant aggregation switches and routers, as well as 3G/4G/5G mobile network IP backhaul devices. Building on its achievements, Accton is now actively engaged in bringing next-generation disaggregated open hardware to leading global operators.
3G/4G/5G Disaggregated Open Networks
As mobile wireless networks move towards 5G, there is an urgent need not only to increase the capacity of backhaul connections, but also to transition to open disaggregated technologies that can deliver the cost economies and flexibility that service providers require. Based on Accton’s extensive experience in delivering backhaul devices for 3G/4G networks, Accton has developed the industry’s first disaggregated cell site gateway router designed for deployment in open mobile wireless networks. The cell site gateway conforms to specifications defined by the Telecom Infra Project (TIP) and leading global mobile operators and consists of an environmentally-hardened compact design with 25 GbE and 100 GbE interfaces, full IEEE 1588 and GPS timing, and low power consumption. As service providers continue to transform their mobile wireless networks over the next few years, Accton will continue to develop the disaggregated open hardware that improves network performance and reduces costs.
Residential Broadband Access
Accton has a successful track record in delivering GPON products stretching back over many years, including GPON ONTs, home gateways, and other ONU devices. Accton has also developed a GPON BOSA (Bi-directional Optical Sub-Assembly) design that fits in a standard SFP form factor. As PON technologies move to 10G and 40G, Accton has developed the industry’s first whitebox virtual Optical Line Terminal (vOLT) devices that are open disaggregated platforms, capable of being deployed in Central Office Re-architected as a Datacenter (CORD) infrastructures. The vOLT devices include either 16 10G XGS-PON interfaces or 64 2.5G GPON interfaces offering flexible options for service providers in their PON networks. With support for various open source SDN and NFV software, these disaggregated platforms can be installed quickly and seamlessly in networks that provide residential or business access services.
As carrier aggregation networks have adapted to increasing bandwidth demands, Accton has delivered the required hardware solutions that build operator infrastructure. These switches, routers, and edge controllers are customized with a variety of port interfaces to meet the requirements of specific aggregation applications. Accton’s extensive carrier-class experience integrates redundant PSUs and fan assemblies into robust NEBS-compliant designs that have been successfully manufactured for Tier-1 operators worldwide.
As service provider networks rapidly transform, Accton is now developing distributed disaggregated chassis systems based on Broadcom’s Jericho2 and Ramon switch ASICs that provide the required deep buffers, port density, and horizontal scale-out flexibility.
These new devices conform to Open Compute Project (OCP) specifications for a distributed disaggregated chassis where a number of switch systems connected through fabric links operate as if they were a single logical router with 100G external I/O links. The 400G fabric links employ a cell-based protocol with fixed-size packets distributed across multiple fabric interfaces forming a redundant, non-blocking leaf-spine topology. With extensive scalability, the distributed disaggregated chassis offers service providers the ideal solution as they strive to keep ahead of the growing bandwidth demands in their aggregation networks.
SOHO / SMB / Enterprise Ethernet Backhaul
Accton’s 32 years of R&D experience and vast array of engineering resources has been effectively applied to produce carrier-grade devices for the IP backhaul market. Carrier access switches, routers, and Universal Customer Premises Equipment (uCPEs) have been custom-designed for many service providers worldwide. These innovative designs meet NEBS Level-3 compliance and include outdoor hardened devices that support Ethernet OAM (IEEE 802.3ah) for fault detection and performance monitoring, and Synchronous Ethernet (IEEE 1588v2). As networks move to 10G, 40G, and 100G speeds with SDN/NFV open-platforms, Accton is ready to deliver cost-effective next-generation IP backhaul solutions.
