Fiber optic isolator is a passive component used for fiber optic communications. As a magneto-optic device, the purpose of optical isolator is to allow light to be transmitted in only one direction.

For the purpose of providing a reliable connection between electronic devices, choosing a proper shielded twisted pair cable is essential to the network using copper cables. EMI (electromagnetic interference) is a disturbance in twisted pair cables. It affects the performance of an electrical circuit by electromagnetic induction, electrostatic coupling, or conduction. But with the help of cable shielding, cables can be immune to the disturbance and keep a stable connection. And this article will present some knowledge about cable shielding. Hope you can find it useful.

In a data center, it is common to see messy cables all over the place. Finding out the right cable becomes a nightmare. However, there are also good examples for well-organized cables that eliminate all the redundant operations due to cable mess. Typically, cable management is a solution used for the installation of equipment in order to secure cables for electrical services. An orderly data center will greatly enhance the working efficiency and ordinary people are more willing to work in a tidy environment. Therefore, cable management is very necessary for data center cabling.

Fiber optical splicing is the act to joint two fibers together by using heat. Generally, there are two types of optical splicing: mechanical splicing and fusion splicing.

Multimode and single-mode optical fiber cables are two different cable types in optical networking. Using a larger core size, multimode fiber cable allows multiple light signals to be transmitted in a single fiber over short distances. Multimode fiber systems offer flexible, reliable and cost effective cabling solutions for local area networks (LANs), storage area networks (SANs), central offices and data centers. Unlike the complex classifications of single-mode fiber, multimode fiber is usually divided into four types of OM1, OM2, OM3, OM4. “OM” is abbreviated for optical multimode, and it is specified by the ISO/IEC 11801 international standard. Of course, these four types of multimode fiber have different specifications (as shown in the following table). The article will compare these four kinds of fibers from the side of core size, bandwidth, data rate, distance, color and optical source in details.
