Atrium Network's dark fibre, ultra-low latency 'Exchange Ring' is connected to PLUS-SX via Atrium Network's POP (point of presence) in PLUS-SX's data centre allowing PLUS-SX to take advantage of a low latency direct optical path and consolidated data feeds. The Exchange Ring is designed to help clients have a simple point of connection to the entire marketplace and the firm's approach to co-location at key liquidity venues means participants are fully operational at all times as exchanges and venues migrate their data centres to new platforms.

Commenting on the connectivity to PLUS-SX, Emmanuel Pellé, COO of Atrium Network said, "We have supported the migration of a number of venues, and are delighted to have helped PLUS-SX with its recent migration and now welcome the company to our fast-growing and far-reaching financial services community. Throughout 2010, we invested in our technology infrastructure and are delighted to see PLUS-SX benefit from access to our network of global POPs."

Commenting on the announcement, Tony Harrop, CTO of PLUS Markets Group said, "Connecting to Atrium Network, and the migration of our data centre, was a straightforward exercise which was eased by connecting directly to Atrium Network's existing infrastructure in place at the data centre. Our trading participants now have another connectivity channel to PLUS-SX and we look forward to inter-connecting with other Atrium Network customers."
