Optical Module
An optical module is a typically hot-pluggable optical transceiver used in high-bandwidth data communications applications. Optical modules typically have an electrical interface on the side that connects to the inside of the system and an optical interface on the side that connects to the outside world through a fiber optic cable. The form factor and electrical interface are often specified by an interested group using a multi-source agreement (MSA). Optical modules can either plug into a front panel socket or an on-board socket. Sometimes the optical module is replaced by an electrical interface module that implements either an active or passive electrical connection to the outside world. A large industry supports the manufacturing and use of optical modules. Electrical Interface Types There have been multiple variants of the electrical interface of optical modules that have been used over the years. Analog direct The earliest forms of optical modules had an analog Non-retu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multi-source Agreement
in the telecommunications industry, a multi-source agreement (MSA) is an agreement among multiple manufacturers to make products which are compatible across vendors, acting as de facto standards, establishing a competitive market for interoperable products. Products that adhere to multi-source agreements (MSAs) include: optical transceivers, such as the SFP, SFP+, XENPAK, QSFP, XFP The XFP (10 gigabit small form-factor pluggable) is a standard for transceivers for high-speed computer network and telecommunication links that use optical fiber. It was defined by an industry group in 2002, along with its interface to other e ..., CFP etc.; fiber optic cables; and other networking devices. MSAs strictly define the operating characteristics of these network devices so that system vendors may implement ports in their devices (e.g. Ethernet switches and routers) that allow MSA compliant devices produced by name brands, as well as third party vendors, to function properly.

Transceiver
In radio communication, a transceiver is an electronic device which is a combination of a radio ''trans''mitter and a re''ceiver'', hence the name. It can both transmit and receive radio waves using an antenna, for communication purposes. These two related functions are often combined in a single device to reduce manufacturing costs. The term is also used for other devices which can both transmit and receive through a communications channel, such as ''optical transceivers'' which transmit and receive light in optical fiber systems, and ''bus transceivers'' which transmit and receive digital data in computer data buses. Radio transceivers are widely used in wireless devices. One large use is in two-way radios, which are audio transceivers used for bidirectional person-to-person voice communication. Examples are cell phones, which transmit and receive the two sides of a phone conversation using radio waves to a cell tower, cordless phones in which both the phone handset and ...

Fiber-optic
An optical fiber, or optical fibre in Commonwealth English, is a flexible, transparent fiber made by drawing glass (silica) or plastic to a diameter slightly thicker than that of a human hair. Optical fibers are used most often as a means to transmit light between the two ends of the fiber and find wide usage in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths (data transfer rates) than electrical cables. Fibers are used instead of metal wires because signals travel along them with less loss; in addition, fibers are immune to electromagnetic interference, a problem from which metal wires suffer. Fibers are also used for illumination and imaging, and are often wrapped in bundles so they may be used to carry light into, or images out of confined spaces, as in the case of a fiberscope. Specially designed fibers are also used for a variety of other applications, some of them being fiber optic sensors and fiber lasers. O ...

Agere Systems
Agere Systems, Inc. was an integrated circuit components company based in Allentown, Pennsylvania. Spun out of Lucent Technologies in 2002, Agere was merged into LSI Corporation in 2007. LSI was in turn acquired by Avago Technologies in 2014. In early 2016, Avago acquired the former Broadcom Corporation, and took on the name Broadcom Inc. Agere was incorporated on August 1, 2000, as a subsidiary of Lucent Technologies and then spun off on June 1, 2002. The name ''Agere'' was that of a Texas-based electronics company that Lucent had acquired in 2000, although the pronunciations of the company names are different. The Texas company was pronounced with three syllables and a hard "g": . The company name was pronounced with two syllables and a hard "g": . Apart from the main office in Allentown, the company also maintained offices and facilities in: * Reading, Pennsylvania, USA: The " Reading Works" facility, formerly Lucent/AT&T and Bell Labs. Closed in 2003. * Orlando, Florida, U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agilent Technologies
Agilent Technologies, Inc. is an American life sciences company that provides instruments, software, services, and consumables for the entire laboratory workflow.

C Form-factor Pluggable
The C form-factor pluggable (CFP, 100G form factor pluggable, where ''C'' is la, centum "hundred") is a multi-source agreement to produce a common form-factor for the transmission of high-speed digital signals. The c stands for the Latin letter C used to express the number 100 (''centum''), since the standard was primarily developed for 100 Gigabit Ethernet systems. CFP standardization The CFP transceiver is specified by a multi-source agreement (MSA) among competing manufacturers. The CFP was designed after the small form-factor pluggable transceiver (SFP) interface, but is significantly larger to support 100 Gbit/s. While the electrical connection of a CFP uses lanes in each direction (RX, TX), the optical connection can support both and variants of 100 Gbit/s interconnects (typically referred to as 100GBASE-SR10 in 100 meter MMF, 100GBASE-LR10 and 100GBASE-LR4 in 10 km SMF reach, and 100GBASE-ER10 and 100GBASE-ER4 in 40 km SMF reach respectively.) ...

100 Gigabit Ethernet
40 Gigabit Ethernet (40GbE) and 100 Gigabit Ethernet (100GbE) are groups of computer networking technologies for transmitting Ethernet frames at rates of 40 and 100 gigabits per second (Gbit/s), respectively. These technologies offer significantly higher speeds than 10 Gigabit Ethernet. The technology was first defined by the IEEE 802.3ba-2010 standard and later by the 802.3bg-2011, 802.3bj-2014, 802.3bm-2015, and 802.3cd-2018 standards. The standards define numerous port types with different optical and electrical interfaces and different numbers of optical fiber strands per port. Short distances (e.g. 7 m) over twinaxial cable are supported while standards for fiber reach up to 80 km. Standards development On July 18, 2006, a call for interest for a High Speed Study Group (HSSG) to investigate new standards for high speed Ethernet was held at the IEEE 802.3 plenary meeting in San Diego. The first 802.3 HSSG study group meeting was held in September 2006. In June 20 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OSFP Transceiver
Small Form-factor Pluggable connected to a pair of fiber-optic cables Small Form-factor Pluggable (SFP) is a compact, hot-pluggable network interface module format used for both telecommunication and data communications applications. An SFP interface on networking hardware is a modular slot for a media-specific transceiver, such as for a fiber-optic cable or a copper cable. The advantage of using SFPs compared to fixed interfaces (e.g. modular connectors in Ethernet switches) is that individual ports can be equipped with different types of transceiver as required. The form factor and electrical interface are specified by a multi-source agreement (MSA) under the auspices of the Small Form Factor Committee. The SFP replaced the larger gigabit interface converter (GBIC) in most applications, and has been referred to as a Mini-GBIC by some vendors. SFP transceivers exist supporting synchronous optical networking (SONET), Gigabit Ethernet, Fibre Channel, PON, and other communic ...
