The Market Need
The Broadband Access market is changing dramatically as vendors introduce new technologies to enable next-generation services. The current technology scenery is quite manifold.
Fiber deployments continue to expand around the world, China and US. Asia continues to be the dominant player globally in the FTTX broadband market, with, for example, China Mobile running the world’s biggest optical transport network, with backbone capacity of around 300 Tbit/s, and 98% of its household customers connected via fiber. The 10 Gbps FTTH deployments continue to build momentum.
In terms of transmission technology, different PON flavors coexist. In 2020 operators will start deploying multi-technology optical line terminals (OLTs), converging GPON, XGS-PON and potentially 25G and 50G PON. While NG-PON2 technology allows to converge the services networks onto a single ODN, providing a significant TCO reduction, its adoption is delayed all the time due to lack of cheap tunable transceivers. XGS-PON is much simpler and most of telecom operators are currently focused on XGS-PON deployments.
While telecom operators increase their investments in FTTX, especially in greenfield locations, user connectivity in brownfield locations is a challenge, particularly in the last few hundred meters to and within the customer premises, over existing copper lines. Running fiber cables there can be heavily regulated, and in some cases impossible. In addition, the installation can be complicated and time consuming. Therefore, some operators are using G.Fast as a complement to the fiber, and others ever more consider 5G Fixed Wireless Access as an alternative to fixed-line copper and fibre services. Analysys Mason Analysts suggest that per-subscriber self-provision costs of 5G FWA and typical wholesale FTTx access costs are balanced, and the market opportunity for 5G FWA is about 20–30% of broadband connections in developed economies and higher in emerging ones.
XGS-PON ultra-fast broadband technology works in 10/10G symmetrical mode, opening new opportunities for operators to monetize their networks. Ethernity’s ENET 4820ZXP/99 flow processor is especially optimized for G.fast solutions, supporting between 8 and 24 modems through 10G G.999.1 channelized Ethernet and featuring an integrated XGS-PON MAC or Ethernet P2P MAC, Carrier Ethernet switch, BBF WT-301, and EFM bonding. The flow processor is implemented on an FPGA SoC with integrated dual-core ARM CPU and programmable logic. The ENET Flow Processor also offers an additional 10G port that enables DPU cascading to support a total of up to 48 G.fast modems.
The technology is based on an extremely efficient architecture, resulting in 80% die size reduction, and can be integrated into a low-cost FPGA that is competitive with ASIC solutions. The ENET 4820ZXP/99 DPU SoC is also designed for reverse power feeding (RPF), and it offers the lowest power solution for 10G uplink with in-house XGS-PON MAC, further optimizing the overall solution cost.
