5G-PON: SK Telecom’s unified distribution network

SK Telecom has detailed a networking architecture based on wavelength division multiplexing-passive optical network (WDM-PON) technology that it says will simplify the rollout of 5G while delivering significant cost savings.

The telecom operator has already deployed the networking architecture, dubbed 5G-PON, for its LTE network and is offering the design to the 5G network standards of the ITU-T.

“SK Telecom is already witnessing a great amount of cost reductions from the deployment of 5G-PON,” says Seungjoo Hong, manager of the Broadband Technology Lab at SK Telecom (pictured).

Part 1: Line-side component and module developments 

• Several vendors announced CFP2 analogue coherent optics   
• 5x7-inch coherent MSAs: from 40 Gig submarine and ultra-long haul to 400 Gig metro  
• Dual micro-ITLAs, dual modulators and dual ICRs as vendors prepare for 400 Gig
• WDM-PON demonstration from ADVA Optical Networking and Oclaro 
• More compact and modular ROADM building blocks

Business services and mobile revive WDM-PON interest

"WDM-PON is many things to many people" - Jon Baldry

It was in 2005 that Novera Optics, a pioneer of WDM-PON (wavelength-division multiplexing, passive optical networking), was working with Korea Telecom in a trial involving 50,000 residential lines. Yet, one decade later, WDM-PON remains an emerging technology. And when a WDM-PON deployment does occur, it is for business services and mobile backhaul rather than residential broadband.

ECOC reflections: final part

Gazettabyte asked several attendees at the recent ECOC show, held in Cannes, to comment on key developments and trends they noted, as well as the issues they will track in the coming year. 

Dr. Ioannis Tomkos, Fellow of OSA & Fellow of IET, Athens Information Technology Center (AIT)

With ECOC 2014 celebrating its 40th anniversary, the technical programme committee did its best to mark the occasion. For example, at the anniversary symposium, notable speakers presented the history of optical communications. Actual breakthroughs discussed during the conference sessions were limited, however.

Ioannis Tomkos

It appears that after 2008 to 2012, a period of significant advancements, the industry is now more mainstream, and significant shifts in technologies are limited. It is clear that the original focus four decades ago on novel photonics technologies is long gone. Instead, there is more and more of a focus on high-speed electronics, signal processing algorithms, and networking. These have little to do with photonics even if they greatly improve the overall efficient operation of optical communication systems and networks.

FSAN close to choosing the next generation of PON

Briefing: Next-gen PON

Part 1: NG-PON2

The next-generation passive optical network (PON) will mark a departure from existing PON technologies. Some operators want systems based on the emerging standard for deployment by 2015. 

“One of the goals in FSAN is to converge on one solution that can serve all the markets"

Derek Nesset, co-chair of FSAN's NGPON task group
