Founded in 1895, Anritsu (Japanese: アンリツ株式会社, English: Anritsu) is a global provider of innovative electronic measurement solutions for existing and next-generation wired and wireless communications systems and operators for more than 110 years. Headquartered in Japan, the company has R&D centers and manufacturing facilities in the United States, Japan, France, the United Kingdom, Denmark and other countries, with sales worldwide .

The core of YOKOGAWA's measurement technology business - the measurement instrument business, with high stability and high reliability of products and always ahead of The Times of measurement technology, make it a trusted partner in the world. Yokogawa Measurement Technology (Shanghai) Co., Ltd. was established on August 09, 2000.

keysight originated from Hewlett-Packard, the first high-tech company in Silicon Valley. 1999 Hewlett-Packard's Electronic Measurement Group was reorganized to become Agilent Technologies, and in 2014 it was spun off and listed again under the name Yestech, becoming a high-tech multinational company 100% focused on electronic test and measurement.

High performance and versatility are two trends in the development of oscilloscopes. Examples reflecting high performance are Agilent Technologies' 63GHz analog bandwidth, 160GSa/s sampling real-time oscilloscope with both low noise and high input dynamic range, and American Liko announced a 65GHz analog bandwidth, 160GS/s real-time sampling rate, 4~40 channels of any channel oscilloscope system, which significantly optimizes the channel selectivity of the oscilloscope.

Fiber optics, the science of transmitting data, voice and images by means of light through thin, transparent optical fibers. In the field of telecommunications, fiber optic technology has practically replaced copper wires in long distance telephone lines, which are used to connect computers in local area networks. Fiber optics is also the basis for fiber optic endoscopes used to examine the inside of the body (endoscopy) or to examine the inside of manufactured structural products.

Optical Module Knowledge | What are the common types of optical modules? In order to meet the demand of various transmission rates, different rates of optical modules are produced: 400GE optical module, 100GE optical module, 40GE optical module, 25GE optical module, 10GE optical module, GE optical module, FE optical module, etc.

In 2015, the competitive landscape of the optical module market was highly fragmented, with less than 20% of the market share held by the leaders and single-digit market shares held by the remaining vendors. However, with the development of technology, research and development and expansion threshold continues to improve, the scale advantage of large leading manufacturers is becoming more and more significant. In addition, in recent years, optical module companies have accelerated mergers and acquisitions, vertical integration of the industry chain, and further increase the concentration of the industry, the global optical module market will gradually move toward concentration.

Optical Module (Optical Module) consists of optoelectronic devices, functional circuits and optical interfaces, etc. The optoelectronic devices include two parts: transmitting and receiving. The role of the optical module is photoelectric conversion, the transmitter side of the electrical signal into optical signals, through the fiber optic transmission, the receiver side and then convert the optical signal into electrical signals.
