Coriant
Coriant was incorporated as an independent company in 2013 as a spin-out from Siemens Optical Networks (NSN ON). The launch of the company was announced for the OFC/NFOEC in March 2013 and on May 6, 2013 Coriant became independent from Nokia Siemens Networks under the ownership of Marlin Equity Partners. Coriant merged with Sycamore Networks (acquired by Marlin Equity in January 2013 and headquartered in Chelmsford, Massachusetts), which continued operating as Coriant America Inc. Marlin Equity merged Coriant and Tellabs (acquired by Marlin Equity in December 2013 Naperville, Illinois), which continued as Coriant. Later, the telco and GPON related components of the company were spun back out as a new company, also called Tellabs. Coriant was acquired by Infinera in 2018. History Coriant originates from the Transmission Technology department of Siemens based in Munich, Germany (Übertragungstechnik - ÜT as it was called in the 1990s). In those days the technology evolved ...

Infinera
Infinera Corporation was an American vertically integrated manufacturer of Wavelength-division multiplexing (WDM)-based packet optical transmission equipment based in San Jose, California. It was also a manufacturer for IP transport technologies, for the telecommunications service provider market. It was a pioneer in designing and manufacturing of large-scale photonic integrated circuits (PICs). The company sold hardware and software networking options for Tier 1 carrier, Internet content provider, cable operator, government, and enterprise networks. In June 2024, Nokia acquired Infinera for $2.3 billion. History Infinera was founded in 2000 as Zepton Networks by Drew Perkins, Jagdeep Singh and David Welch. It raised its first round of funding in April 2001. The startup remained in stealth mode until its first products were launched in 2004, although a few early media articles did describe the company's component technology - a photonic integrated circuit in indium phosphi ...

Naperville
Naperville ( ) is a city in DuPage and Will counties in the U.S. state of Illinois. It is a southwestern suburb of Chicago located west of the city on the DuPage River. As of the 2020 census, its population was 149,540, making it the state's fourth-most populous city. Naperville was founded in 1831 by Joseph Naper. The city was established by the banks of the DuPage River and was originally known as Naper's Settlement. By 1832, over 100 residents lived in Naper's Settlement. In 1839, after DuPage County was split from Cook County, Naperville became the county seat, which it remained until 1868. Beginning in the 1960s, Naperville experienced a significant population increase as a result of Chicago's urban sprawl. Naperville is home to Moser Tower and Millennium Carillon, one of the world's four largest carillons. It is also home to an extensive parks and forest preserve network, including Centennial Beach. The city has two school districts, 203 and 204. Naperville's lar ...

Tellabs
Tellabs, Inc. is a global network technology company that provides networking and communications solutions to both private and governmental agencies. The company offers a range of products and services, including optical transport systems, access systems, managed access solutions, and network management software. The company was founded by Michael Birck in 1974 and is headquartered in Carrollton, Texas. It is currently owned by Marlin Equity Partners, who established an independent business for its product portfolio to accelerate the development of Optical local area network (OLAN) technology. Designed for enterprise and government clients, OLAN uses fiber, which is faster, more secure, and more stable compared to traditional copper infrastructure. History Early years Tellabs traces its roots to a meeting in 1974 over a kitchen table in suburban Chicago. According to company founder Michael Birck, a group of six men with backgrounds in electrical engineering and sales drank ...

Telecommunications
Telecommunication, often used in its plural form or abbreviated as telecom, is the transmission of information over a distance using electronic means, typically through cables, radio waves, or other communication technologies. These means of transmission may be divided into communication channels for multiplexing, allowing for a single medium to transmit several concurrent Session (computer science), communication sessions. Long-distance technologies invented during the 20th and 21st centuries generally use electric power, and include the electrical telegraph, telegraph, telephone, television, and radio. Early telecommunication networks used metal wires as the medium for transmitting signals. These networks were used for telegraphy and telephony for many decades. In the first decade of the 20th century, a revolution in wireless communication began with breakthroughs including those made in radio communications by Guglielmo Marconi, who won the 1909 Nobel Prize in Physics. Othe ...

Terabit Per Second
In telecommunications, data transfer rate is the average number of bits (bitrate), characters or symbols ( baudrate), or data blocks per unit time passing through a communication link in a data-transmission system. Common data rate units are multiples of bits per second (bit/s) and bytes per second (B/s). For example, the data rates of modern residential high-speed Internet connections are commonly expressed in megabits per second (Mbit/s). Standards for unit symbols and prefixes Unit symbol The ISQ symbols for the bit and byte are ''bit'' and ''B'', respectively. In the context of data-rate units, one byte consists of 8 bits, and is synonymous with the unit octet. The abbreviation bps is often used to mean bit/s, so that when a ''1 Mbps'' connection is advertised, it usually means that the maximum achievable bandwidth is 1 Mbit/s (one million bits per second), which is 0.125 MB/s ( megabyte per second), or about 0.1192 MiB/s ( mebibyte per second). Th ...

STM-16
Synchronous Optical Networking (SONET) and Synchronous Digital Hierarchy (SDH) are standardized protocols that transfer multiple digital bit streams synchronously over optical fiber using lasers or highly coherent light from light-emitting diodes (LEDs). At low transmission rates, data can also be transferred via an electrical interface. The method was developed to replace the plesiochronous digital hierarchy (PDH) system for transporting large amounts of telephone calls and data traffic over the same fiber without the problems of synchronization. SONET and SDH, which are essentially the same, were originally designed to transport circuit mode communications, e.g. DS1, DS3, from a variety of different sources. However, they were primarily designed to support real-time, uncompressed, circuit-switched voice encoded in PCM format. The primary difficulty in doing this prior to SONET/SDH was that the synchronization sources of these various circuits were different. This meant that ...
