Single-mode fiber (SingleModeFiber): The central glass core is very thin (the core diameter is generally 9 or 10μm), and only one mode of fiber can be transmitted. Single-mode fiber has very small inter-mode dispersion and is suitable for long-distance communication, but it also has material dispersion and waveguide dispersion. In this way, single-mode fiber has […]
Not long ago, Hubei Province held a science and technology conference. An exciting news from Wuhan Research Institute of Posts and Telecommunications, the laboratory of the Institute once again set the world record for optical transmission, reaching 400T per second. This means that an optical fiber with the thickness of a hair can accommodate 4.8 […]
200G AOC active optical cable overview The rapid development of data centers has increased user demand. In order to meet the needs of users, the transmission rate of optical communication transmission has also increased and developed, from the previous 10G and 25G to today’s 100G, 200G and so on. Facing the high-speed, high-density, low-cost, and […]
C114 News on July 21 (Ace) A report from market research company Omdia shows that AT&T and Discovery have reached an agreement under which the two parties will merge WarnerMedia and Discovery and split the entity into an independent global entertainment company. The two companies expect the transaction to be completed in mid-2022. This transaction […]
When the optical cable is formed into a cable, there are two protection requirements for the optical fiber: one is that the optical fiber is less stressed; the other is that the optical fiber should be waterproof. The outermost layer of the optical cable is a plastic sheath, the inside is a metal sheath, and […]
Wuhan Optics Valley, in the wire drawing workshop of YOFC Co., Ltd., the world’s largest preform with a diameter of 20 cm and a length of 3 meters—a transparent quartz round rod with a material ratio that is roasted at a high temperature of over 2000 ℃ , Emitting a dazzling light. After the drawing […]
Industry: Optical Communications Report Name: 2021 Optical Communication Project Feasibility Study Report Key words: optical communication, feasibility study report, feasibility study, project approval In order to help optical communication enterprises to successfully implement projects such as administrative examination and approval of government departments, land acquisition approval, bank loans, investment cooperation, IPO fundraising, capital application, and […]
In March 1976, at Nanwang Mountain in Wuhan, the earth already exhaled the breath of spring. In a laboratory transformed from a cleaning room of the Wuhan Research Institute of Posts and Telecommunications, a 17-meter-long glass filament, the leading quartz optical fiber in China, flows slowly through Zhao Zisen’s hands. Detecting instrument detection: The optical […]
An optical fiber with a hair thickness ranges from a laboratory product to 4.8 billion people around the world can talk online at the same time; an industry from scratch has been introduced from a complete set to an annual output of thousands of times around the earth, creating a number of global optical fiber […]
Optical fiber, this small glass filament, carries more than 90% of the world’s optical communication transmission. As a technical expert in the national 973, 863, science and technology support program projects, and major national defense security projects, Li Shiyu’s dream is to let China’s optical fiber technology keep up with or even surpass the world […]
