  by www.fiber-mart.com Today's data centers are no longer just one or a few computer rooms, but a group of data center clusters. In order to realize the normal operation of various Internet services and application markets, data centers are required to operate in coordination. The real-time mass exchange of information between data centers has created the demand for data center interconnection networks, and optical fiber communication has become a necessary means to achieve interconnection.   Different from the traditional telecommunication access network transmission equipment, the data center interconnection requires higher speed, lower power consumption, and smaller size of the switching equipment in order to realize larger and denser transmission of information. The  SFP optical transceiver  is a core factor that determines whether these performances can be achieved. The information network mainly uses optical fiber as the transmission medium, but the current ca...

  by www.fiber-mart.com The  MPO fiber patch cord  adopts MPO (Multi-fiberPushOn) connector. The precise connection of the patch cord is realized through two guide holes and guide pins with a diameter of 0.7mm on the left and right of the end face of the ferrule. At present, the most widely used is the 12-pin MPO connector. 12-core to 24-core MPO fiber optic patch cords, with good performance and low loss, are widely used in FTTX, wide area networks (WANs), local area networks (LANs), telecom networks, 40/100/200G network solutions and other wiring environments which are best solutions to realize high density and high bandwidth network.   The Pre-Terminated MTP/MPO Technology is with polarity Classification. The three polarity methods ensure accurate bidirectional configuration - Type A, Type B, Type C. Each end of the MTP/MPO trunk fiber patch cord is equipped with an MTP/MPO connector.   Pre-terminated MPO/MTP Trunk Cables and Breakout Fiber Patch Cord   ...

  by www.fiber-mart.com When two optical fibers are connected, due to the difference in position, shape and structure of the two optical fibers, the energy cannot be 100% from one optical fiber to the other. That is, there will be connection loss. In order to minimize connection loss, the two fibers must be precisely aligned. The main function of the optical fiber adapter is to quickly connect two optical fibers, so that the optical signal can be continuous to form an optical path. And how does the optical fiber adapter realize the accurate connection of the optical fiber?   There are many types of  optical fiber adatpers , but the precise alignment between optical fibers depends on two factors. One is a ceramic ferrule with a precise inner diameter, outer diameter, and concentricity, and the other is a ceramic sleeve with a slit. The ceramic sleeve is a very smart design.   You can see how the two optical ferrules are precisely aligned through a ceramic sleeve. The ...

  by www.fiber-mart.com Many people are confused about the hanging of aerial optical cables. In fact, there are two methods for aerial optical cables laying: one is "fixed-pulley traction method", including "manual traction method" and "mechanical traction method"; the other is "cable tray moving and releasing method". Next, we will take a detailed look at the concrete operation of the latest methods of aerial cable construction technology.   (1) Fixed-pulley traction method. When hanging the optical cable, the cable tray should be set first, and the big pulley for laying the optical cable shall be fixed on the pole at the up and down positions. A small pulley (guide pulley) shall be hung every 10-20 m on the suspension line in each pole, and the traction rope shall be put into the small pulley. Then, make the traction head, connect the traction rope with the optical cable, and prepare for laying.   ① When applying manual traction method, please ...

  by www.fiber-mart.com Central tube optical cable possesses loose tube structure of the central tube. Because its optical fiber is in the center of the cable, which has good bending characteristics and compact structure, it has become the main type after being introduced. Wuhan Institute of Post and Telecommunications Science, based on the characteristics of China's vast territory and small optical fiber communication capacity at that time, has developed the first optical cable patent product with Chinese characteristics, that is, the central tube optical cable.   There are several forms of central tube structure. The first one has no steel belt armor, which is strengthened by parallel galvanized steel wire and has the problem of poor water penetration and bad low-temperature characteristics. Later, steel belt armor is added, and it is the first forming technology of optical cable steel strip longitudinal wrapping in China, adopting classification molding, steel belt flat bel...

  by www.fiber-mart.com The emergence of CWDM (coarse wavelength divisio   n multiplexing) technology allows operators to find a low-cost, high-performance transmission solution. Because of its low cost, low power consumption, small size, and other advantages, CWDM has been widely used in metro transport networks. Many domestic and foreign manufacturers have also begun to develop and launch products, and ITU is also accelerating its standardization process. CWDM technology improves fiber utilization and gives operators and users greater flexibility. This article will discuss the key technologies such as  CWDM  characteristics, wavelength selection, and fiber type, and make a detailed comparison between CWDM and DWDM. Finally, the application and development of CWDM are prospected.   Advantages of CWDM system metro transport networks   The biggest advantage of the CWDM system is its low cost, which is mainly manifested in several aspects of device, power con...

  by www.fiber-mart.com Fiber optic adapters (also known as fiber optic flanges, mating sleeves and couplers), are fiber optic active components. Optical fiber adapters are the most useful optical passive devices in optical fiber communication systems. The fiber optic adapter plays the role of aligning the sleeve. In addition, the fiber optic coupler is usually equipped with metal or non-metal flanges to facilitate the installation and fixation of the connector.Both ends of the fiber adapter connect with fiber connectors of different interface types to achieve conversion between different interfaces such as FC, SC, ST, LC, MTRJ, MPO, and E2000. It is widely used in optical fiber distribution frames (ODF), optical fiber communication equipment, Instruments, etc..   Features of  Fiber Optic Adapter   1.
