fiberopticThe second XGS-PON Interoperability Plugfest, which concluded in Tauxigny, France recently, brought together 13 tech companies from across the globe in an attempt to improve the interoperability of one of the latest iterations of PON technology. The XGS-PON plugfest focused on interoperability between XGS-PON Optical Line Terminations and Optical Network Units (ONUs), and the coexistence between various PON technologies, including G-PON and NG-PON2.

XGS-PON is based on the ITU-T’s latest Recommendation (ITU-T G.9807.1), providing a symmetrical 10Gbit/s capability over a fiber infrastructure that can co-exist with legacy 2.5Gbps G-PON.

Participating companies included ADTRAN, Broadcom, Calix, CommScope, Econet, Huawei, Intel, MT2, Nokia, Sagemcom, TiBit Communications and ZTE, according to a press release. The event was organized by Laboratoire des Applications Numériques (LAN), in collaboration with the Full Service Access Network (FSAN) Group and the Broadband Forum.

“Momentum around PON has been growing and this second event underpins the wider activities being carried out,” said Thierry Doligez, director of LAN, in a prepared statement. “The industry is very much working together to ensure that when it comes to deploying PON technologies, operators have a wide choice of interoperable solutions and can deploy the technology cost-effectively.”

All equipment vendors, FSAN and Broadband Forum members were able to improve the interoperability of their products by testing them against other solutions presented during the event, the release said.

“Efficient interoperability testing and its next step ONU certification process is essential to Orange before envisioning any significant deployment of a technology generation,” said Christian Gacon, Orange Labs director of wireline network and infrastructure, in a prepared statement. “XG(S)-PON test events prove the basic standards sanity check and enable the next step consisting in common technical specifications amongst major operators worldwide to focus the industry towards a bulk first market for the technology.”

For the Broadband Forum, the Plugfests are an extension of the organization’s PON interoperability activities, which include the BBF.247 G-PON and XG-PON1 ONU Certification program, which is being extended to include XGS-PON and NG-PON2.
