SAN DIEGO -- OFC 2019 -- The increasingly influential O-RAN Alliance has given the Passive Optical Network (PON) access network sector got a 5G boost by deciding to adopt PON technology as an option in fronthaul networks, according to an AT&T executive.
Speaking here today in a 5G symposium session, Kent McCammon, a lead member of Technical Staff at AT&T, said the O-RAN Alliance, which boasts many of the world's major Tier 1 operators as its members, voted unanimously at a meeting in Madrid on February 21 to adopt PON as an option for mobile fronthaul, the connection in a disaggregated radio access network (RAN) between centralized baseband controllers and remote standalone radio heads at cell sites.
The move should encourage the development of low-latency PON technologies by the vendor community conforming to "Cooperative Transport Interface" specifications being developed by the O-RAN members that will make PON options suitable for the operators' needs. "PON was not developed with low latency in mind," noted McCammon.
The O-RAN Alliance's move runs in parallel with a very similar development at the ITU, which has been working for some time on low-latency PON specifications: McCammon noted that there may be moves to align the terminology used by the groups, both of which count AT&T as an active member.

PON technologies have for some time been regarded as an option for fronthaul, though other options, including dark fiber and WDM, have been regarded as more suitable. Even with PON there is a broad range of options and flavors, from asymmetrical or symmetrical 10G PON to NG-PON2, the access technology being championed by Verizon.
Whichever way the O-RAN Alliance swings is likely to have an impact on vendor R&D plans and operator strategies as the industry group is becoming increasingly influential and attracting the participation of most (if not all) of the major players from the operator and vendor community: Huawei is the notable absentee from the vendors, while Ericsson only recently joined and with a limited remit.
Optical components firms such as NeoPhotonics and Source Photonics, and systems vendors such as Adtran, Calix, Huawei and Nokia, will no doubt be interested in how this O-RAN decision might impact fronthaul planning and technology requirements.

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.
The MDU market continues to face fierce competition among service providers due to tech-savvy residents (i.e., millennials), demand from building owners and management companies, plus the favorable economics of bulk contracts. However, no MDUs are the same, so service providers must use multiple technologies and inconsistent deployment models, increasing operational complexity and rollout costs.
The MDU market itself is evolving as residents adopt smart-home technologies, generating rising demand for smart apartments with built-in connected thermostats, keyless entryways and doors, and video doorbells. This evolution presents both new challenges and opportunities. In other words, service providers must consider innovative service-delivery strategies to compete and win.
In this Broadband World News and ADTRAN webinar, Kurt Raaflaub, Head of Strategic Solutions Marketing, will highlight emerging MDU broadband Internet trends and challenges. In addition, Kurt will outline the next-generation service creation and delivery platform, built on open standards, that allows service providers to connect millions of underserved MDUs, enables creation of user-driven services, and reduces operational complexity and costs.
Plus, special guest, Alice Lawson, Broadband and Cable Program Manager for the City of Seattle, will discuss Seattle’s B4B-Build For Broadband initiative that addresses best practices in planning for MDU telecommunication infrastructure.
