Verizon already has 100Gbps (gigabit-per-second) connections over its optical core networks across continents. Now the carrier is bringing that speed to its metro networks, which enterprises tap into for high-speed data connections. The metro networks so far have been limited to 10Gbps or 40Gbps.
Though the carrier doesn’t expect many customers to start ordering 100Gbps connections soon, it is preparing for the future.
Verizon’s 100-gigabit U.S. backbone technology forms the basis of a high-speed, low-latency network for financial trades that was inaugurated between Chicago and New York last month. It can complete a stock trade in as little as 14.5 milliseconds, according to the carrier.

Verizon said it has begun to use the same general architecture for high-speed land-based networks that it already uses for its connections across oceans. That architecture, based on a mesh of cables, gives traffic across its core network more alternate routes to take if one cable breaks. This is a step up from a ring architecture, in which the network recovers by sending bits the other way around the ring if one spot on it is damaged.
Verizon already has mesh networks across the Pacific and across the Atlantic, each with eight alternate paths.
