Hamamatsu Photonics has announced the completion of a new building at its Beijing Hamamatsu Photon Techniques subsidiary to expand its manufacturing capacity, as well as its and research and development activities in China. Operations at the new building located at the Langfang Factory, have already begun.

Researchers at Caltech have developed a new semiconductor laser that could transmit data at higher speeds along an optical fibre. The work could pave the way for faster broadband internet and other optical fibre communications.

The new laser design has a much higher spectral purity than the semiconductor distributed-feedback (DFB) laser that is at the heart of today’s fibre optic communications. The new laser has more than 10 times the linewidth improvement compared to commercial semiconductor lasers, the researchers state, with the possibility of further increase in coherence.

Coriant, a supplier of metro-to-core transport solutions, has announced the latest progress in its collaboration with Juniper Networks to create an integrated packet transport network (IPTN).

Recent joint R&D between the two networking innovators resulted in the first multi-vendor line side interworking between router and DWDM system suitable for long haul (LH) transmission.

Poor broadband provision in the UK is damaging children's education in rural areas, according to a survey.

Figures from insurance company NFU Mutual, which surveyed 1,600 parents, suggest that a third of those with internet access in rural areas believe the provision is too slow.

Researchers at IBM have set a new record for data transmission over a multimode optical fibre, a type of cable that is typically used to connect nearby computers within a single building or on a campus. The achievement demonstrated that the standard, existing technology for sending data over short distances should be able to meet the growing needs of servers, data centers and supercomputers.
