Ethernet cables are the standard cables used for almost all purposes that are often called patch cables. In an article “How to Choose Ethernet Cable”, we know that Ethernet cables can be categorized into many types, like straight-through and crossover Ethernet cable, UTP or STP, Cat5 or Cat6, etc. But we know little about the pins and wiring in Ethernet…

Driven by the cloud computing and improvement of technology, 21st century witnesses a major shift from traditional enterprise data centers to much larger cloud data centers. These large data centers require a much higher-performance network, and need to interconnect many thousands of servers with predictable bandwidth and low-latency. Cisco 10G Catalyst 4500-X series switch is the highest throughput 10G Ethernet…

As a communications subsystem, a fiber optic data link connects inputs and outputs (I/O) from electronic subsystems and transmits these signals over fiber optic cables. More specifically, this data link converts an electrical input signal into an optical signal, then sends the optical signal over an optical fiber, and finally converts the optical signal back to an electrical signal, actually…

Wavelength as we have been heard so many times in fiber optics, is not simply the term used to refine the color of the light. The light used in fiber optics in not the one that we can see by our eyes, as we use light in the infrared region which has wavelengths longer than visible light, typically around 850…

Driven by the growing bandwidth requirement, data center designers have to install more and more fiber optic cables in a given space, which results in mess cable management and large maintenance cost. Thus finding an easy-to-manage and space-saving method for high-density cabling is becoming a hot issue for data center managers. LC to LC fiber cable, with its low interface…

In optical communication networks, optical transceivers are some of the most fundamental pieces of hardware for a smooth network. Nowadays, as telecommunication market is surrounded by a sea of fiber optic transceivers of different brands, originals or third-party ones, users are met with many choices. But since many name-brand networking companies charge too much for their transceivers, in most cases,…
