Dasan Zhone introduced a family of multi-protocol smart gateways this week that are designed to help service providers future-proof their networks as they migrate them from 10G GPON up to NG-PON2.
Whether or not providers opt to include a several-year-stop at XGS-PON, PON upgrades are costly -- and eliminating the need to replace optical network terminals (ONTs) and optical line terminals (OLTs) is a boon for operators.
"Many operators plan to take a step-wise approach when expanding their networks using 10G GPON technologies, aligned with the specific needs of their business," said Teresa Mastrangelo, principal analyst at Broadbandtrends, in a statement. "A large majority of these service providers will focus on XGS-PON for the first phase of their rollouts, while future-proofing their networks for the advantages of NG-PON 2."
Once price prohibitive, 10G GPON's costs are dropping as demand for 10-gig deployments grows worldwide. Cloud-based consumer offerings, such as video-on-demand, eSports and 4K/8K televisions, plus evolving gaming solutions that require high-speed, low latency broadband, are also driving operators to invest in next-generation PON. Future-proofing, however, is key, Mastrangelo said.
The DZS 5200 smart gateways give providers a choice between 10/10G symmetrical PON technology and 10G Active Ethernet using SFP+ optics, according to DZS. This choice offers more seamless connectivity to existing FTTx and enterprise business subscribers via one common network, the vendor noted. Initial models allow one fixed 10G copper LAN port and four GE ports; there are options for voice or PoE+ / PoE++. New models in the 5200 family will use the same platform and support NG-PON 2 as the availability and price/performance of optics drop.
"Offering our customers a common platform with choice among technologies and form factors is core to our 10G solution development. In this way, DZS can best serve the diverse needs of operators across the globe," said Seungdong Lee, chief technology officer at DZS. "We believe that 10/10 symmetrical XGS-PON is the best upgrade path to evaluate in 2019."
The ongoing debate around GPON vs EPON can get as heated as discussions around politics and religion, but both technologies offer some advantages over the other depending on the needs your network is servicing.
In this webinar, we will focus on the facts around the GPON vs EPON debate and how that technological decision is almost always made based on factors outside the technology itself.
In this insightful Light Reading radio show, Kurt Raaflaub, Head of Strategic Solutions Marketing, will outline the key service provider challenges, deployment considerations, next-gen Gigabit technologies, and service models to win market share in the rapidly growing MDU market.
