Frequently Asked Questions

What is DBOI technology?

Lightfleet’s Direct Broadcast Optical Interconnect (DBOI) is the first simultaneous, all-to-all, optical interconnect technology. It speeds the flow of data between “nodes” (such as multiple processors inside a server), thus eliminating any bottlenecks that today’s switches and other interconnects introduce due to their hierarchical structure. DBOI greatly reduces the number of required cables and external switches. The result is increased communication speed, better reliability, lower operational costs, lower capital costs, lower cooling costs, and lower electrical power costs.

Why is DBOI technology important?

DBOI creates a fundamental change in how computing can be done. Without DBOI, programmers have had to build in delays in their applications so the hardware can keep up.  DBOI also drastically reduces the power required for communications between devices such as processors, computers and storage devices.

Is this innovation unique to Lightfleet?

Yes, Lightfleet cumulatively has 16 domestic and international patents either granted or pending, with several others in the filing process.

What is ODM and how is it superior to switched fabrics?

The Optical Distribution Module (ODM) makes obsolete the switch based fabric in wide use today. When connected as simple building blocks, the Lightfleet ODM creates a switchless optical fabric that allows any type of packet and any type of network topology. It maintains optimal performance even under heavy load and does this with self-routing messages without the need for the cost and complexities of a control plane and its software.

How is ODM different from DBOI?

DBOI is the underlying technology inside the ODM but is a new implementation of the technology. Having proven the DBOI in a tight cluster system interconnect, we have now used it to architect a scalable network fabric. It is used instead of a switch for the connection of any node, from processors to memory to storage.

Is the Lightfleet ODM fabric scalable?

Designed explicitly for the demands and exponential growth of big-data, each ODM contains high bandwidth, electro-optical data paths with built in high speed logic. They can be connected together from one to thousands, supporting up to millions of nodes. Today’s largest data centers and highest traffic loads can be easily supported by a Lightfleet Switchless Optical Fabric with plenty of room for growth beyond any needs projected by the industry at this time.
