Seven Solutions sets new record for long distance White Rabbit High Accuracy time over fiber link

The White Rabbit link covers an approximate distance of 1,350 km (840 miles) and was deployed in collaboration with Optiver US, a financial company, to connect Chicago and New Jersey trading locations. This link is formed by six long-distance White Rabbit hops using WR-Z16 and WR-ZEN TP devices connected by a combination of DWDM and SyncE-compliant transponders over a public telecommunication fiber network.

The finance industry is being pushed by MIFIID II regulation to register most of its operations with timestamps legally traceable to a Coordinated Universal Time (UTC) reference with 1 microsecond granularity and 100 microseconds maximum divergence. This poses a challenge for the sector, since the most commonly used solutions to provide time in the industry do not comply with the requirements.
