ONT stands for Optical Network Terminal. The MyRepublic ONT is a device provided by our partner Nucleus Connect, a national Operating Company who runs the active infrastructure of the all fibre Next Generation National Broadband Network. The ONT connects to the Opennet's Termination Point (TP) with an optical fibre cable and connects to your router via an LAN / ethernet cable. It is basically a modem, translating signals from the fibre optic line from your TP into electronic signals that your router can read.

At one point in time, only 1 port of your ONT is active and supplying your MyRepublic connection. The rest should have no internet access. If you subscribe to another fibre broadband line from MyRepublic or from another internet service provider using the Nucleus Connect ONT, only then would the other ports be made active and usable. Unless specifically told to, do NOT press the “Reset” button on your ONT as it will perform a hard reset that will cause it to stop working. To do a simple reset on your ONT, please perform a power cycle where you disconnect the ONT’s power supply and wait about 5 minutes for its internal cache to clear.

If you’re experiencing connection issues (e.g. lack of internet access or slow speeds), an key troubleshooting step is to try connecting your computer directly to the ONT to see if the problem goes away. To do this, get a network cable (also known as an ethernet / LAN cable) and connect your computer to the ONT, plugging it into the ONT’s active port (the one supplying your MyRepublic broadband). If the problem goes away with a direct connection to the ONT, then the issue does not lie with the MyRepublic connection to your residence, but somewhere within your home networking setup i.e. with your router or your wireless connection or your computer. If you see a red signal light in the ONT's Link LED or no light is visible at all, then there's likely an issue with the fibre infrastructure - which means a disruption with the physical fibre line (managed by OpenNet) or the active infrastructure (managed by Nucleus Connect).

In 1989, Tim Berners-Lee invented the World Wide Web, an Internet-based hypermedia initiative for global information sharing while at CERN, the European Particle Physics Laboratory. He wrote the first web client and server in 1990. His specifications of URIs, HTTP and HTML were refined as web technology spread.

He is Director of the World Wide Web Consortium (W3C), a Web standards organization founded in 1994 that develops interoperable technologies (specifications, guidelines, software, and tools) to lead the Web to its full potential. He is a founding Director of the Web Science Trust (WST) launched in 2009 to promote research and education in Web Science, the multidisciplinary study of humanity connected by technology. Berners-Lee is also a Director of the World Wide Web Foundation, launched in 2009 to coordinate efforts to further the potential of the Web to benefit humanity.

At MIT, Berners-Lee is the 3Com Founders Professor of Engineering in the School of Engineering, with a joint appointment in the Department of Electrical Engineering and Computer Science at the Laboratory for Computer Science and Artificial Intelligence (CSAIL). He is also a Professor in the Electronics and Computer Science Department at the University of Southampton, UK.

In 2001 Berners-Lee became a Fellow of the Royal Society. He has been the recipient of several international awards. In 2004 he was knighted by H.M. Queen Elizabeth, and in 2007 he was awarded the Order of Merit.

Robert Kahn is Chairman, CEO and President of the Corporation for National Research Initiatives (CNRI), which he founded in 1986 after a thirteen year term at the U.S. Defense Advanced Research Projects Agency (DARPA). CNRI was created as a not-for-profit organization to provide leadership and funding for research and development of the National Information Infrastructure.

After receiving a B.E.E. from the City College of New York in 1960, Dr. Kahn earned M.A. and Ph.D. degrees from Princeton University in 1962 and 1964 respectively. He worked on the Technical Staff at Bell Laboratories and then became an Assistant Professor of Electrical Engineering at MIT. He took a leave of absence from MIT to join Bolt Beranek and Newman, where he was responsible for the system design of the ARPNET, the first packet-switched network. In 1972 he moved to DARPA and subsequently became Director of DARPA's Information Processing Techniques Office (IPTO). While Director of IPTO he initiated the United States government's billion dollar Strategic Computing Program, the largest computer research and development program ever undertaken by the federal government. Dr. Kahn conceived the idea of open-architecture networking. He is a co-inventor of the TCP/IP protocols and was responsible for originating DARPA's Internet Program. Until recently, CNRI provided the Secretariat for the Internet Engineering Task Force (IETF). Dr. Kahn also coined the term National Information Infrastructure (NII) in the mid 1980s, which later became more widely known as the Information Super Highway.

Vint Cerf is the co-designer of the TCP/IP protocols and the architecture of the Internet. In December 1997, President Bill Clinton presented the U.S. National Medal of Technology to Cerf and his colleague, Robert E. Kahn, for founding and developing the Internet. In 2004, Cerf was the recipient of the ACM Alan M. Turing award (sometimes called the “Nobel Prize of Computer Science”) and in 2005 he was given the Presidential Medal of Freedom by President George Bush.

Cerf began his work at the United States Department of Defense Advanced Research Projects Agency (DARPA) playing a key role in leading the development of Internet and Internet-related data packet and security technologies. Since 2005, he has served as vice president and chief Internet evangelist for Google. In this role, he is responsible for identifying new enabling technologies to support the development of advanced, Internet-based products and services. He is also an active public face for Google in the Internet world.

He also served from 2000-2007 as chairman of the board of the Internet Corporation for Assigned Names and Numbers (ICANN), an organization he helped form. Cerf served as founding president of the Internet Society from 1992-1995, and in 1999 served a term as Chairman of the Board.

Ever wonder why we can shop at Amazon, read news from BBC, watch Youtube videos, trade stocks on New York and Tokyo stock exchanges. They all have something in common, all are located on servers and datacenters outside Singapore. The answer lies with submarine cables and internet exchanges. Read on ...

Submarine Fibre Cable

What you see above is a submarine fibre communications cable. With a diameter of 69 millimeter (2.7 inches), it carries 99% of all international traffic (i.e., internet, telephony and private data) and connects every continent on Earth with the exception of Antarctica. These amazing fibre optic cables traverse oceans and span hundreds of thousands of kilometers.

Ship Cable Innovator

Above is the CS Cable Innovator, it is specifically designed for laying fibre optic cable and is the largest of its kind in the world. Built in 1995 by Kvaerner Masa of Finland, it is 145 meters in length (476 ft), with a breath of 24 meters (78 ft) and a depth of 8.5 meters (28 ft). It is capable of carrying up to 8500 tons of fibre optic cable. The ship has 80 cabins, of which 42 are officer cabins, 36 are crew cabins and two are representative suites. The normal endurance of the vessel at sea is 42 days, but this can be extended to approximately 60 days through logistical support.
