Infrared links may soon replace wires in data centers.

Engineers are proposing to change the communication in data centers that soon may become hassle free by eliminating most of the wires and substitute to infrared free-space optics for communications. 

Researchers from Pennsylvania State University tried radio frequency signaling, the beams became wide over short distances. Where the Microsoft engineers found that radio -frequency signaling resulted in high interference, limited active links and limited throughput, the amount of data that can go through a system.

Mohsen Kavehrad from PSU said“ We use a free space optical link. It uses a very inexpensive lens, we get a very narrow infrared beam with Zero interference and no limit to the numbers of connections with high throughput”, 

The (Pennsylvania state University) jointly with Carnegie Mellon University working on the Free –space optical Inter- rack nEtwork with high Flexibility architecture project.  Study suggests that “ It would use infrared lasers and receivers mounted on top of data center racks to transmit information, and laser modules are rapidly does not need reconfigure to obtain a target on any rack.” According to Kavehrad, data center may have almost 400.,000 servers on racks with minimal human interference that could break the laser beams.
