Dark Fiber – Is It the Dark Side or the Right Side?

As the optical technology grows more sophisticated and expand into high bandwidth optical backbone connectivity, enterprises are now turning to the private and secure dark fiber network. By leasing dark fibers, network operators can cut down the labor cost of developing fiber networks. What’s more, enterprises can use their own optical technician and networking equipment to connect multiple locations to…

Whether to Go for Aerial or Underground Deployment

In the fiber optic network, a carefully constructed network requires calculated planning and a high level of installation. It is not as easy a cavemen can do it, as many factors should be taken into account when installing a fiber optic network, such as construction costs, time constraints, existing infrastructure, and so on. There are two main types of land…

Guide to BiDi Optical Transceiver

Pluggable optical transceivers typically use two fibers to send and receive optical signals between switches, firewalls, servers or routers. One fiber is to receiving data from networking equipment, and the other is to transmit data to the networking equipment. However, a new class of optical transceiver—BiDi transceiver uses only a single fiber to send and receive signals. The reduction in…

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…

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…
