  by www.fiber-mart.com With the rapid development of the network, the 40G network has now become so popular, and the 100G network is also widely used. Nowadays, the traditional fiber optical LC connection can no longer meet the high speed and high density requirements of the data center. In this case, it becomes very important to obtain a higher transmission rate and find a suitable solution for high-density wiring. However, the emergence of MTP/MPO connection standards and MTP/MPO related products is indeed a good news for high-density cabling. It can replace 12 or 24 LC connectors at the same time. Therefore, it is the perfect solution for high-performance data transmission.   The  MPO/MTP patch panel  occupies a dominant position in the high-density wiring environment. As a high-density pre-terminated fiber optic equipment, it has the characteristics of flexible deployment and can not only provide conversion between MTP/MPO connectors and LC or SC connectors and help high-density n

The rapid increase in the number of network links will result in the data center space of traditional optical fiber cabling being cramped and difficult to manage. The application of MPO optical fiber connector/optical fiber jumper is based on this demand, which can accommodate the optical cable connection of high-speed and large-capacity optical communication system to meet the 400G high-speed transmission demand.   MPO  (Multi Push On) is a type of multi-core optical fiber connector. Usually 12-core optical fiber is arranged in a row. It can support one or more rows of optical fibers in the same MPO connector. According to the number of cores discharged in the connector, it is divided into one row (12 cores) and multiple rows (24 cores or more) .The size of the MPO connector is the same as that

  by www.fiber-mart.com The data center has become the engine of modern life, and the growing network information is transmitted and stored at high speed through the data center. Most of the connection distances inside the data center are short, ranging from a few meters to a few hundred meters. In these short-distance high-speed data communications, multimode optical fibers and optical modules with vertical cavity surface emitting lasers (VCSEL) as the core components have been widely used. Compared with the single-mode transmission scheme, the multi-mode scheme uses a low-cost, low-power laser to achieve fast and efficient coupling between the fiber and the laser. Multi-mode fiber can achieve higher transmission rate or longer transmission distance than copper cable, and lower cost than single-mode fiber system.At present, the internal connection rate of the data center has reached 100 Gbit/s, and 400 Gbit/s is just around the corner. The industry has been developing new types of mul

Nowadays, commonly used switches are mainly divided into  commercial network switches and industrial Ethernet switches. In order to meet the flexible and changeable industrial environment and anti-interference aspects, there is a particularly large gap between industrial switches and commercial switches. In contrast, the functions of industrial switches are more practical. So, what are the differences and advantages of industrial Ethernet switches compared with commercial network switches? Today, UnitekFiber will share with you some information about them.   There is no essential difference between  industrial switches  and commercial switches in terms of data link layer, network layer, protocol layer, etc., but for the real-time requirements of industrial control, industrial Ethe

  by www.fiber-mart.com To realize the internal optical network interconnection of data centers, optical transceivers are indispensable. As the number of ports and density increase, half of the cost of optical networks in data centers will be occupied by optical transceivers. At present, 100G interconnection technology has been widely adopted in the newly-built data centers of major Internet companies, and 400G interconnection technology will be commercially available on a large scale in the next 2 to 3 years. Therefore, the implementation technology of 400G optical transceiver has become the focus important part of the industry.   According to this progress, ultra-large-scale data centers are expected to start deploying 400G Ethernet in 2020, and 400G Ethernet will enter the large-scale deployment phase in about 2022.   Early 400G optical transceivers used 16-channel 25Gbps NRZ implementations (such as 400G-SR16), and used CDFP or CFP8 packages. The advantage is that it can borrow the

  by www.fiber-mart.com In the 5G era, the demand for optical cables is the most prominent problem encountered in the deployment of 5G fronthaul networks. The demand for 5G fronthaul bearer solutions is growing rapidly. In order to reduce the consumption of optical fiber resources, passive wavelength division schemes have been widely used.   Wavelength division multiplexing (WDM), including  CWDM  (coarse wavelength division multiplexing) and DWDM (dense wavelength division multiplexing), etc. Refers to the coupling of multiple signals of different wavelengths on a single fiber for simultaneous transmission. It has multiplexers and demultiplexers. The multiplexer (MUX) combines multiple signal wavelengths in one optical fiber at the transmitting end; the demultiplexer (DEMUX) transmits multiple wavelengths in one optical fiber at the receiving end. The signals of each wavelength are separated. The main purpose of wavelength division multiplexing is to increase the available bandwidth o

  by www.fiber-mart.com Fiber cable is a kind of communication line in which a certain number of fibers are assembled according to a certain way. Some of them are wrapped with sheaths or outer sheaths, which are used to protect the fibers and realize the transmission of optical signals. Optical cables usually consist of one or more fibers.   There are different types of fiber cables, and there are various classification methods. Here are some commonly used classification methods.   First, classification according to structure According to the structure, it can be divided into layered stranded fiber cable and bundle tube fiber cable.   (1) Layered stranded fiber cable The layered stranded fiber cable is a rounded core composed of several reinforcing parts which hold the loosen sleeve around the center of the fiber. Metal or non-metal reinforcements are located in the center of the optical cable, and loose sleeves containing fiber cables are arranged around the reinforcements.   (2) Bund

  by www.fiber-mart.com The Relationship Between Optical Fiber and Optical Cable   In this world with developed networks, fiber optic cables are an inevitable trend to replace other communication tools. However, many people who are not in contact with the communications industry think that optical fibers and optical cables sound the same, and they will think that they are the same product. In fact, optical fibers are not equal to optical cables. Today, fiber-mart.com will introduce to you the relationship between optical fiber and optical cable, hoping to help friends who are not in contact with optical fiber and cable.   The optical fiber is made of pure silica (glass) by a special process to be drawn into a glass tube thinner than a hair with a medium in the middle, which can transmit a huge amount of information in a short time. The diameter of the fiber core originally produced is very small, and the current standard is only 0.125 mm. Optical fiber factories will cover the surface
