  by www.fiber-mart.com Switching is a technology collectively referred to the requirements of transmitting information at both ends of the communication, using manual or equipment to automatically complete the information to be transmitted to the corresponding route that meets the requirements. A network switch in the broad sense is a device that performs information exchange functions in a communication system.   In the computer network system, the exchange concept is proposed to improve the shared working mode. The hub we introduced before is a shared device. HUB itself cannot identify the destination address. When A host in the same LAN transmits data to B host, the data packets are transmitted in a broadcast manner on the network based on HUB. Each terminal determines whether to receive it by verifying the address information of the data packet header. That is to say, in this working mode, only one group of data frames can be transmitted on the network at a time. If a col...

  by www.fiber-mart.com The difference of End Grinding Angle PC is Physical Contact. PC is a microsphere grinding and polishing, the surface of the ferrule is ground into a slight spherical surface, and the fiber core is located at the highest point of bending. This can effectively reduce the air gap between the fiber components and bring the two fiber end faces into physical contact.   UPC (Ultra Physical Contact). The end face of the UPC connector is not completely flat, there is a slight arc to achieve more accurate mating. UPC is based on PC to optimize the end surface polishing and surface finish, and the end surface looks more domed.   APC (Angled Physical Contact) is called beveled physical contact, and the end face of the fiber is usually ground into an 8 ° bevel. The 8 ° angle bevel makes the fiber end face tighter, and reflects light through its bevel angle to the cladding instead of returning directly to the light source, providing better connection performance...

  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 ...

  by www.fiber-mart.com Nowadays,  fiber optic patch panel  is becoming popular in optical fiber wiring systems, especially in high-density wiring environments such as data centers and server rooms. Fiber optic patch panel is convenient for people to access the optical fiber cables in the box, and can protect the optical fiber cables well. In addition, the drawer type structure helps the high-density wiring and cable management. Since the optical fiber cable is fragile and easily damaged by pulling, bending or squeezing, we should be very careful when installing the optical fiber cables in the fiber optic patch panel.   The installation of fiber optic patch panel can be divided into three steps: installing the optical fiber patch panel on the rack, introducing the fiber optic cable into the optical ffiber optic patch panel, and planning the optical fiber cable path in the optical fiber patch panel. Here is the detailed description of the three steps:   1. How do...

  by www.fiber-mart.com What is 24 fibers MTP/MPO Cabling? 24cores MTP/MPO cabling is a high-density wiring solution based on 24 core MTP/MPO cables. Compared with 24 fibers cabling that uses three 8 fibers MTP/MPO cables or two 12 fibers MTP/MPO cables, one 24 fibers MTP/MPO cable can provide higher density.   24 fiber MPO/MTP Cabling in 40G/100G Network Solution Compared with the traditional single-core dual-core optical fiber cabling, the  24 fibes MPO/MTP cabling  has more advantages to some extent. Although the duplex LC connector occupies the same space as a single MTP connector, a single MTP connector can support 24 cores and can achieve a higher connection density. Therefore, when the network grows from 10Gbps to 40G or 100G, it will use 24 fiber MTP/MPO structured cabling, which is convenient to support more and more advanced applications (such as AR, VR). 24 fibers MTP/MPO cabling based on 24 fibers MTP/MPO cables can provide different types of solutions fo...
