Color Code Standard of Ethernet Cable – T-568B and T-568A

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…

SFP+ DAC Cables for Cisco Catalyst 4500-X Series Switch

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…

Introduction to Fiber Optic Data Links

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…

Decoding the Wavelength in Fiber Optics

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…

What You Need to Know About LC Connector Families?

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…

Why Choose HP Compatible SFP+ Transceivers?

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,…

Be Careful When Working With Fiber Optic Cable

It’s known that safety issues or hazards are commonplace in both copper and fiber cabling installation, faced by installers. And when it comes to this topic, many people think that copper cabling installation needs more attention and caution, since they carry electricity. In comparison, optical fibers are safer because of the light they carry. But actually, this concept is misplaced….

Graded Index or Step Index Multimode Fiber

Fiber optic cable is the media of telecommunications infrastructure, enabling the transmission of high-speed voice, video, and data traffic in enterprise and service provider networks. We usually see single mode and multimode optic fibers available on the market with distinct specifications utilized in different network infrastructure. Compared with single mode fiber patch cables, multimode fiber has a larger core diameters,…
