Reference excerpt

MRV Communications was a telecommunications company based in Chatsworth, California. MRV Communications was acquired by ADVA Optical Networking on August 14, 2017 for a reported $69 million.

History MRV was founded in 1988 by Shlomo Margalit and Zeev Rav-Noy as a maker of Metro and Access optoelectronic components. MRV also established the subsidiary LuminentOIC, who makes fiber-to-the-premises (FTTP) components.

Product development In the 1990s, MRV produced Ethernet switching and Optical Transport for Metro and campus environments. MRV began building switches and routers used by carriers implementing Metro Ethernet networks that provide Ethernet services to enterprise customers and multi-dwelling residential buildings. In 1999, MRV was named as the prime vendor to deploy the world’s first Metro Ethernet national network in Swedish Telecom. That same year the company introduced a Linux-based IP router based on network processor technology. The company introduced the industry's first Packet-Optical platform with integrated IP/MPLS/Ethernet and WDM technologies in 2005, and got MEF CE 1.0 certification. In 2008, they introduced the industry's first purpose-built 10GE demarcation device for Carrier Ethernet Access services. In 2009, MRV Technologies deployed OptiSwitch Ethernet demarcation in the industry’s first 4G LTE commercial Mobile Backhaul network and introduced one of the lowest-latency optical products (Fiber Driver) for High-Frequency Trading. In 2010, the company introduced industry first Physical layer 10G switch for the lab automation market. The company was among the first vendors in the industry to pass MEF CE 2.0 certification in 2012. In 2014, they introduced a new flagship next-generation WDM metro product line, the OptiDriver series and in 2015 introduced the industry’s first 100G purpose-built CE 2.0 NID, OptiPacket. In 2015, the company introduced the industry's first 100G purpose-built CE 2.0 NID, OptiPacket.

Acquisitions and investments In 1992, MRV acquired Galcom Networking, a company based in Tel Aviv, Israel. MRV Communications acquired Fibronics International from Elbit Ltd. in 1996. A year later, the company acquired Interdata, a French-based system integrator specializing in optical networks, architecture, and network security for operators, enterprises, and large jurisdictions. In 1998, the company paid $35 million for Xyplex Networks. This acquisition enhanced the development of remote management and IP routing functionality for WAN services and added distribution channels in the United States and Europe. In 2001, the company acquired Alcadon AB, a Nordic-based system integrator of passive and active optical networking infrastructure. In 2010, the company announced the sale of Source Photonics, Inc. to Francisco Partners. MRV Technologies sold Alcadon AB, a Nordic-based system integrator of passive and active optical networking infrastructure, to Deltaco AB in 2012.

Worked examples

Example 1 — a first encounter with MRV Communications

Start with the simplest possible case. Write down what MRV Communications claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to MRV Communications before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about MRV Communications ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of MRV Communications

In research: MRV Communications appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses MRV Communications in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: MRV Communications is common in secondary-school and first-year university syllabi. It links to neighbouring topics Companies based in Los Angeles, Defunct computer companies based in California, Defunct computer companies of the United States, so understanding it makes those chapters shorter.
In everyday life: Look for MRV Communications outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
