Cailabs reveals its one-of-a-kind 45-mode spatial multiplexer
French deep-tech player Cailabs has just beat a world record by developing a 45-mode spatial multiplexer, enabling all 45 modes of a fiber to be addressed. This technological feat was presented for the first time at the world’s largest telecommunications conference, OFC (The Optical Networking and Communication Conference & Exhibition), which took place in March 2018.
Cailabs provides a critical component for spatial multiplexing. Multi-Plane Light Conversion (MPLC) technology, created by Cailabs’ co-founders at the Kastler Brossel quantum optics laboratory, makes it possible to convert light emitted by currently-used single-mode fibers into light shapes propagated by multi-mode fibers, which are then able to function as parallel communication channels.
Permanent technological advances
Since 2014, Cailabs has been marketing spatial multiplexers adapted to the needs of telecom R&D teams who are developing the communication networks of the future based on spatial multiplexing. Thanks to the efficiency of Cailabs’ spatial multiplexers, KDDI, the Japanese operator and leading telecommunications company in Asia for more than 60 years, set a new fiber-capacity world record of 10 Pb/s (10 million Gb/s) over a multi-mode fiber in a laboratory. Since 2018, Cailabs has been addressing all possible channels of commercial multi-mode fibers and, in being able to generate 45 different modes in an individual fiber, is taking full advantage of the transmission possibilities offered by optical communications. This technological breakthrough, based on a technological foundation of 13 patent families, was presented at OFC’s “post-deadline papers” session last March, which brings together the most innovative technological achievements within the telecommunications sector.
From R&D to industrialization
“Having demonstrated that the number of modes is no longer an obstacle, Cailabs is now focusing on the industrialization of this technology, leveraging it to bring value across a wide range of applications,” says Jean-François Morizur, CEO of Cailabs. In fact, the efficiency of MPLC technology already makes the SDM relevant to LAN (local network) renovations, aeronautical cabling, optical amplifiers and optical communications in free space.
Cailabs is currently working on increasing production volume and making its products more reliable, all the while aiming to comply with aerospace environmental regulations.
