Frame Relay is a standardized wide area network (WAN) technology that specifies the physical and data link layers of digital telecommunications channels using a packet switching methodology. Originally designed for transport across Integrated Services Digital Network (ISDN) infrastructure, it may be used today in the context of many other network interfaces.
In fiber-optic communications, wavelength-division multiplexing (WDM) is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths of laser light. This technique enables bidirectional communications over a single strand of fiber, also called wavelength-division duplexing, as well as multiplication of capacity.
Photonics is a branch of optics that involves the application of generation, detection, and manipulation of light in form of photons through emission, transmission, modulation, signal processing, switching, amplification, and sensing. Photonics is closely related to quantum electronics, where quantum electronics deals with the theoretical part of it while photonics deal with its engineering applications. Though covering all light's technical applications over the whole spectrum, most photonic applications are in the range of visible and near-infrared light. The term photonics developed as an outgrowth of the first practical semiconductor light emitters invented in the early 1960s and optical fibers developed in the 1970s.
The Optical Internetworking Forum (OIF) is a prominent non-profit consortium that was founded in 1998. It promotes the development and deployment of interoperable computer networking products and services through implementation agreements (IAs) for optical networking products and component technologies including SerDes devices.
A passive optical network (PON) is a fiber-optic telecommunications technology for delivering broadband network access to end-customers. Its architecture implements a point-to-multipoint topology in which a single optical fiber serves multiple endpoints by using unpowered (passive) fiber optic splitters to divide the fiber bandwidth among the endpoints. Passive optical networks are often referred to as the last mile between an Internet service provider (ISP) and its customers. Many fiber ISPs prefer this technology.
A metropolitan-area Ethernet, Ethernet MAN, or metro Ethernet network is a metropolitan area network (MAN) that is based on Ethernet standards. It is commonly used to connect subscribers to a larger service network or for internet access. Businesses can also use metropolitan-area Ethernet to connect their own offices to each other.
A photonic integrated circuit (PIC) or integrated optical circuit is a microchip containing two or more photonic components which form a functioning circuit. This technology detects, generates, transports, and processes light. Photonic integrated circuits utilize photons as opposed to electrons that are utilized by electronic integrated circuits. The major difference between the two is that a photonic integrated circuit provides functions for information signals imposed on optical wavelengths typically in the visible spectrum or near infrared (850–1650 nm).
Silicon photonics is the study and application of photonic systems which use silicon as an optical medium. The silicon is usually patterned with sub-micrometre precision, into microphotonic components. These operate in the infrared, most commonly at the 1.55 micrometre wavelength used by most fiber optic telecommunication systems. The silicon typically lies on top of a layer of silica in what is known as silicon on insulator (SOI).
Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of infrared or visible light through an optical fiber. The light is a form of carrier wave that is modulated to carry information. Fiber is preferred over electrical cabling when high bandwidth, long distance, or immunity to electromagnetic interference is required. This type of communication can transmit voice, video, and telemetry through local area networks or across long distances.
The Centre for Ultrahigh bandwidth Devices for Optical Systems was a collaboration of Australian and international researchers in optical science and photonics technology. CUDOS is an Australian Research Council Centre of Excellence and was formally launched in 2003.
Arelion, formerly named Telia Carrier and TeliaSonera International Carrier (TSIC), is a provider of telecommunication services based in Solna, Sweden. Arelion is a tier 1 network provider, assigned Autonomous System number AS1299. Since 2021, the name Twelve99 is also used in technical contexts.
An optical mesh network is a type of optical telecommunications network employing wired fiber-optic communication or wireless free-space optical communication in a mesh network architecture.
Shaygan Kheradpir is an American businessman and technology executive. Kheradpir holds a bachelor's, master's and doctoral degree in electrical engineering from Cornell University. He is best known for driving transformational change through the use of technology of Verizon where he led technology, Barclays bank as COO, Juniper Networks and Coriant as CEO. He is an honorary member of Cornell Engineering council and served on the advisory board of the US National Institute of Standards and Technology VCAT [22].
A super-channel is an evolution in dense wavelength-division multiplexing (DWDM) in which multiple, coherent optical carriers are combined to create a unified channel of a higher data rate, and which is brought into service in a single operational cycle.
David F. Welch is an American businessman and research scientist. Welch is a pioneer in the field of optical devices and optical transport systems for telecommunications networks. Welch first made it possible to commercially deploy reliable 980 nm laser pumps, needed in low noise optical amplifiers employed in dense wavelength division multiplexing (DWDM) telecommunications systems. He also achieved the first commercial optoelectronics integrated circuit, several years ahead of any competing research or developments laboratory.
Transmode, headquartered in Stockholm, Sweden, was a publicly listed provider of networking solutions, which enable fixed line and mobile network operators to cost effectively address the increasing capacity needs created.
