How to Build A Passive Optical LAN (Local Area Network)

Local area network (LAN) is being widely deployed in the enterprise, university, hospital, army, hotel and places where a group of computers or other devices share the same communication link to a server. Most of the traditional LAN are based on Ethernet copper cable. As more and more devices and cables are adding to the existing copper based LAN, problems come out. Bottlenecks of bandwidth, cabling space, cable infrastructure are limiting the network services. To better organize the local area ...

Centralized Splitting vs Distributed Splitting in PON Based FTTH Networks

Passive optical network (PON) based FTTH access network is a point-to-multipoint, fiber to the premises network architecture in which passive optical splitters are used to enable a single optical fiber to serve multiple premises. The optical fiber splitter can be placed in different locations of the PON based FTTH network, which involves using centralized (single-stage) or distributed (multi-stage) splitting configurations in the distribution portion of the network. In fact, both methods have it...

Guideline for Fixed Fiber Attenuator

As a beginner in fiber optic network, I used to think that the optical power should be as strong as possible. Even sometimes we use optical amplifiers to improve the optical signal. So what is the fiber attenuator used for? As we know, the source of the single mode fiber is laser, the power of which is extremely strong. Therefore we can use single mode fiber to achieve long distance transmission. But, if the transmission distance over single mode fiber is too short, too much light may overload a...

How to Design Your FTTH Network Splitting Level and Ratio?

In Passive Optical Network (PON), optical splitters play an important role in Fiber to the Home (FTTH) networks by allowing a single PON interface to be shared among many subscribers. Optical Splitters are installed in each optical network between the PON Optical Line Terminal (OLT) and the Optical Network Terminals (ONTs) that the OLT serves. During the deployment of fiber to the home passive optical network, usually, we will face some physical access network design problems. This article may h...

ABC of PON: Understanding OLT, ONU, ONT and ODN

In recent years, Fiber to the Home (FTTH) has started to be taken seriously by telecommunication companies around the world, and enabling technologies are being developed rapidly. There are two important types of systems that make FTTH broadband connections possible. These are active optical networks (AON) and passive optical networks (PON). By far the majority of FTTH deployments in planning and in deployment use a PON in order to save on fiber costs. PON has recently attracted much attention d...

Comprehensive Understanding of FTTx Network

A simple understanding of FTTx is Fiber to the x, x here can be replaced such as H for home, B for building, C for curb or even W for wireless etc. It is a new technology used in today's network. As we know, compared to copper or digital radio, fiber’s high bandwidth and low attenuation easily offset its higher cost. To install fiber optics all the way to the home or the users' working places has always been the goal of fiber optic industry. Thanks to optical fiber all the way to subscriber, we ...

How Much Do You Know About PLC Splitter?

As fiber optic link becomes more and more acceptable by average consumers, Passive Optical Network (PON) systems are more widely deployed in common homes. Fiber optic splitter is an indispensable passive optical device in PON systems. Optical splitters can be divided into Fused Biconical Taper (FBT) splitter and Planar Lightwave Circuit (PLC) splitter. PLC splitter is newer than FBT splitter and is also the focus of this post. What Is PLC Splitter? PLC splitter, also called Planar Waveguide ...

Differences Between FBT Splitter and PLC Splitter

In FTTx and PON architectures, optical splitter plays an increasingly significant role to create a variety of point-to-multipoint fiber optic networks. But do you know what is a fiber optic splitter? In fact, a fiber optic splitter is a passive optical device that can split or separate an incident light beam into two or more light beams. Basically, there are two types of fiber splitter classified by their working principle: fused biconical taper splitter (FBT splitter) and planar lightwave circu...

AON vs PON Networks: Which One to Choose for FTTH Systems

Fiber to the home (FTTH) is a system which installs optical fiber from a central point directly to individual buildings such as residences and apartments. The deployment of FTTH has come a long way before subscribers adopt optical fibers instead of copper lines to achieve broadband Internet access. There are two basic paths to deploy high-speed FTTH network: active optical network (AON) and passive optical network (PON). Then AON vs PON networks: what's their difference? What Is Passive Optic...
