Alcatel-Lucent, EneCom carry out field trial of and TWDM-PON technologies in Japan

1 Jun 2015

Energia Communications (EneCom), which provides community-oriented telecommunications and information processing services in Japan’s Chugoku region, has teamed up with Alcatel-Lucent to trial next generation, ultra-broadband access technologies that will pave the way for the delivery of higher capacity business and residential services, including ultra-high definition 8K television and video-on-demand (VoD). Paris-based equipment vendor Alca-Lu is deploying technology to increase the speed of EneCom’s existing copper wire network, which it says will deliver 1G ultra-broadband access to multi-dwelling apartment buildings. The equipment maker’s Time Wavelength Division Multiplexing-Passive Optical Network (TWDM-PON) technology is being used over Energia Communications’ existing PON fibre-to-the-home (FTTH) network, using the same fibre. TWDM-PON allows service providers to increase network capacity from 1Gbps to 40Gbps using multiple wavelengths. Alcatel-Lucent’s IP/MPLS 7750 Service Router will be used to backhaul traffic from the access aggregation network to the telco’s core network. The pair confirmed that the field trial shows that TWDM-PON can coexist on the same fibre with 1Gbps PON, providing a total capacity of up to 40G.

Japan has one of the highest penetrations of FTTH ultra-broadband services in the world and connections have now reached more than 37 million households, according to the Ministry of Internal Affairs and Communications.
