NEWS: UPDATE TRIALS FOR NEOPHOTONICS 400G TRANSCEIVER
NeoPhotonics has shipped its new 400G capable ClearLight CFP2-DCO transceiver for end customer trials. Te firm describes the transceiver module as ‘the industry’s first’, able to deliver up to 32Tb of capacity per fibre by using internal optics that can support 80 channels of 64GBd data at 75GHz wavelength channel spacing, combined with the latest generation of 7nm node digital signal processing (DSP) technology. It is the first in a series of
coherent module solutions based on its photonic integrated circuit
(PIC) platorm. Te module incorporates a number of coherent solutions in a pluggable module, including the new extended tuning range ultra-narrow linewidth tunable C++ laser, Micro-ITLA. It also features the company’s
high-bandwidth 64GBd C++ ICRTM receiver and C++ CDMTM modulator. Tis module supports tuning across the full ‘Super C-band’ and provides more spectrum and resulting capacity. Te ClearLight CFP2-DCO
module tunes to 75GHz spaced wavelength channels when
operating at 64GBd and 16 QAM to support 400G transmission in 400ZR and 400ZR+ modes for cloud data centre interconnect and metro network applications. Waveguide gratings are available for multiplexing and de- multiplexing with 75GHz channel spacings and filter responses optimised for 64GBd coherent signals, including for ‘Super C-band’ use. For long haul and regional
applications, the module uses 64GBd and QPSK modulation to deliver 200Gb per wavelength
UK TELECOMS INDUSTRY MAKES GIANT LEAP IN R&D
SSE ENTERPRISE TELECOMS CHOSEN FOR FIBRE NETWORK IN UK MIDLANDS
SSE Enterprise Telecoms was selected by education specialist provider Jisc to help launch the ‘Jisc Midlands’ network. It is a combination of the current Jisc East and West Midlands networks and will enable education and research facilities in the region to tap into connectivity speeds of up to 100Gb/s. Te contract was awarded following a competitive procurement
process. A key element of the project is the ability to incorporate other service providers’ networks. As well as its own core network, SSE Enterprise Telecoms will use fibre from three other telecommunications firms to help ensure the best value. It will also undertake strategic construction to achieve an optimum bespoke design, based on the most advantageous routes, rather than dependent on fibre ownership. Colin Sempill, CEO at SSE, said: ‘Tis network will help Midlands-
The latest data from the UK’s Office of National Statistics (ONS) has put the telecoms industry as the fastest growing sector when it comes to research and development spend. Businesses in the sector increased their spending on research and
development by £192m to £947m in 2018, according to the ONS. This rise of 25.4 per cent is a four-year high. However, the sector is still some way off its all-time high of £1.5bn set in 2007, analysis by research and development tax relief specialist, Catax highlights. Comparatively, the total spend on research and development
by telecoms firms totalled £755m in 2017 and £797m in 2016. Investment in research and development is continually growing across the board in the UK, rising £1.4bn to £25bn in 2018, an increase of 5.8 per cent. Manufacturing was a key driver, with £16.3bn of spending, up 4.7
per cent, and pharmaceuticals maintained its lead with £4.5bn of research and development spend, a rise of 3.3 per cent. The number of research and development staff employed by UK
businesses also continued to grow, rising 7.3 per cent year-on-year, to exceed 250,000 full-time equivalents for the first time. Mark Tighe, chief executive at Catax, said: ‘The telecoms industry
is extremely important to the UK strategically and it is reassuring to see such growth in investment. ‘There is still some way to go if this investment is to recover to
levels seen before the financial crash, however, and it is vital this happens if Britain is to continue to be a key technological player on the world stage. For the first time a quarter of a million people nationwide are engaged full-time in keeping the UK at the cutting edge. This is going to make a huge difference to Britain’s prospects outside the EU.’

based education and research centres connect and collaborate across the region and the wider UK, as well as access the internet and cloud applications. It will enable them to connect to global research centres, further driving innovation and supporting the UK’s ambition of being a leader in research and further education.’ Neil Shewry, head of delivery at Jisc, added: ‘Our customers need
fast, reliable and resilient networks that support their high bandwidth demands. We’re excited to be partnering with SSE Enterprise Telecoms, a continuation of our long-standing relationship, to launch the Jisc Janet Midlands network, addressing these requirements. SSE Enterprise Telecoms’ ability to design a resilient network, which aligned with our price point, was a key consideration when making the decision to award the contract.’
