His lifelong work is about to be shown at two exhibitions in the UK, as detailed in an interview with the Financial Times. It made me wonder whether anyone is doing the equivalent for telecom and datacom? Mega data centres as IT cathedrals?</p>
<p>When writing features for FibreSystems Europe, I repeatedly asked for high-resolution striking images. The magazine's editors always wanted photos that included people, like Maurice Broomfield's<strong> </strong>photos.&nbsp; Getting hold of such images did happen but not often.</p>
<p>Inspired by the <a href="http://www.ft.com/cms/s/2/2f60ef04-1b6c-11df-838f-00144feab49a.html">Financial Times&rsquo; interview and Maurice Broomfiel</a><a href="http://www.ft.com/cms/s/2/2f60ef04-1b6c-11df-838f-00144feab49a.html">d's beautiful images</a>, some of the better images sent are presented here.</p>

<p>This is the silicon photonic start-up&rsquo;s first announced modulator. The design has been developed in conjunction with Sun Microsystems as part of the DAPRA Ultraperformance Nanophotonic Intrachip Communications (UNIC) programme.</p>

<p><strong><span style="color: black;">Event:</span></strong></p>
<p><span style="color: black;">Alcatel-Lucent has launched its 1870 Transport Tera Switch (TTS) that has a switch capacity of 4 Terabits-per-second (Tbps). The platform switches and grooms traffic at 1Gbps granularity while supporting lightpaths up to 100Gbps. </span></p>
<p><span style="color: black;">&ldquo;It is designed to address the explosion of traffic in core networks, driven by video and the move to cloud computing among others,&rdquo; says Alberto Valsecchi, vice president of marketing, optics activities at Alcatel-Lucent.</span></p>
<p><span style="color: black;">The 1870 TTS supports next-generation Optical Transport Network (OTN), carrier Ethernet and SONET/SDH protocols, as well as generalized multiprotocol label switching/ automatically switched optical network<em> </em>(GMPLS/ ASON) control plane technology to enable network management and traffic off-load between the IP core and optical layers.</span></p>

<p>Optical equipment and transceiver makers have much in common. &nbsp;Both must contend with the challenge of yearly network traffic growth and both are addressing the issue similarly: using faster interfaces, reducing power consumption and making designs more compact and flexible. &nbsp;</p>
<p>Yet if equipment makers and transceiver vendors share common technical goals, the market challenges they face differ. For optical transceiver vendors, the challenges are particularly complex.</p>
