MODE-GAP, the European collaborative R&D project, which is investigating space-division multiplexing (SDM; or using afew-mode optical fiber’s separate spatial modes to carry separate data channels) to help solve the potential upcoming capacity crunch within the telecommunications networks, has unveiled its latest commercial product: a few-mode fiber erbium-doped amplifier (FM-EDFA).

Researchers at TU Eindhoven demonstrate record data transmission over a specially fabricated fibre
Achieved throughput of 255 Terabits/s is more than 20 times better than current commercial technology
Researchers from Eindhoven University of Technology (TU/e) in the Netherlands and the University of Central Florida (CREOL) in the USA, report in the journal Nature Photonics the successful transmission of a record high 255 Terabits/s over a new type of fibre allowing 21 times more bandwidth than currently available in communication networks. This new type of fibre could be an answer to mitigating the impending optical transmission capacity crunch caused by the increasing bandwidth demand. (more…)
The MODEGAP project is continuously show-casing that mode-division multiplexing technology can improve the capacity of optical transmission systems greatly.
After demonstrating the largest capacity transmitted over a 3-mode supporting few-mode fiber (FMF) with few-mode EDFA (see http://modegap.eu/?p=344) and being the first to demonstrate the feasibility to upgrade legacy single-mode transmission systems with FMF technology during a fieldtrial in Austria (http://modegap.eu/?p=986), now the MODEGAP project is one of the first to demonstrate long-haul reach using a full FMF-technology transmission link.
A record reach of 1020 km was demonstrated, using close to normal span lengths of 60 km and FM-EDFAs. On each of the three modes 128-Gb/s dual-polarization QPSK was transmitted.

Researchers at EU-funded project MODE-GAP (‘Multi-mode capacity enhancement with PBG fibre’) are working to boost the internet’s capacity by developing and testing advanced fibre technologies.
Their work could be the building blocks for the high-capacity access networks needed for channelling new applications such as high-definition TV, interactive gaming, and video-on-demand directly via fibre to subscribers …
