Active Optical Network

Deciding Between Passive Optical Networks and Active Optical Networks

The FTTH solution is regarded as the best option with respect to transmission quality and bandwidth. The deployment of FTTH (Fiber To The Home) access networks has gone through a long way before subscribers use fiber cables instead of copper lines to achieve broadband Internet access. FTTH is a form of fiber-optic communication delivery with fiber extending from the central…

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…

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…

Fiber optic data links

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…
