ADTRAN signals support of multivendor FTTH networks

ADTRAN, Inc., (NASDAQ: ADTN) has made it easier for its fiber-optic broadband access equipment to be paired with elements of competitors' portfolios. The systems house has announced the availability of open APIs on its multiservice access nodes (MSANs) and G.fast distribution point nodes and MDU nodes for fiber to the home/building (FTTH/B). It also has unveiled a line of universal optical network terminals (ONTs) designed to be compatible with competitors' FTTH PON optical line terminals (OLTs).

The new capabilities are designed to enable service providers to use a "best in class" approach to their broadband access network deployments, rather than having to select equipment from a single vendor.

The initiative covers a wide variety of platforms. For example ADTRAN says the open interfaces on its MSANs enable support of ONTs and Wi-Fi integrated residential gateways developed by other vendors. Meanwhile, its G.fast fiber-to-the-distribution point and 10G FTTH MDU platforms support TR-301 defined YANG and RESTful interfaces; this makes them interoperable within an open multi-vendor MSAN network, according to the company. And ADTRAN's customer premises equipment, including FTTH-enabled IP business gateways, FTTH Wi-Fi integrated residential gateways, and micro ONTs, are compliant to BBF.247 to promote interoperability in a multi-vendor access network.

"A variety of important ultra-broadband access technologies including G.fast, GPON, NG-PON2, and 10 Gigabit Services PON (XGS-PON) will require operators to leverage a more flexible deployment model to maximize return on investment and speed time-to-market as these technologies are deployed within multi-vendor environments," commented Erik Keith, principal analyst for broadband networks and multi-play services, Current Analysis. "Given the prevalence of multi-vendor networks, it is crucial that these networks be open and interoperable, both to enable this impending network transition and to facilitate revenue growth, and ultimately, to ensure that the industry moves away from the static, silo-based approach that has limited network flexibility and new services growth for years."
