FTTX Solutions
Technically, when you start the planning stage of a new cabling installation, you should not have to worry about the types of applications used. Still, it is a good idea to have an understanding of the networking application you are cabling for and how that can effect the use of the cabling system.

In this article, you will learn to know how many components used in a cabling system. For example, you will know the differentiate between the various types of network cable and their application in the network. Let's read it seriously.

New network architectures have been developed to reduce the cost of installing high bandwidth services to the home, often lumped into the acronym FTTx for "fiber to the x". Fiber to the home (FTTH) is a technology wherein a single optic fiber runs from the central office of a telecom service provider to the customer's residence. The technology is also known at times as FTTx wherein the meaning is broader and covers offices, apartment buidings,communities, and various other configurations.

Fiber To The X (FTTx) is different from a traditional fiber optic network that would be used for a local area network (LAN) application. In most FTTX applications, only one optical fiber is used. That single optical fiber passes data in both directions. This is very different from a LAN application where the transmit optical fiber sends data in one direction and the receive optical fiber sends data in the other direction. In a LAN application, both optical fibers can have data passing through them at the same time.

The most mature and common of the network applications is Ethernet. Over the past 25 years, despite stiff competition from more modern network architectures, Ethernet has flourished. In the past 10 years alone, Ethernet has been updated to support speeds of 100Mbps, 1Gbps (about 1000Mbps) and 10Gbps; currently 40 and 100 Gigabit Ethernet are being standardized in the IEEE 802.3b committee. Forty and 100 Gigabit Ethernet will be deployed over optical fiber for 100 meters or greater, and research is progressing to make it available over UTP for distances up to 10 meters.

With the spread of computer applications, along with the rapid development of network technology, the campus network has become an essential school information infrastructure. The implementation of the campus network, for schools to adapt to new developments and make fuller use of existing teaching resources for teching, management has provided a guarantee. Construction of intelligent building network as the physical basis. Using a variety of transmission media of the communication management device and the terminal connected. Its performance can affect the normal operation of the network and the length of life. Therefore, the design of a scientific and rational, optimized campus cabling system is to further play a variety of network equipment functions, the information and communication technologies to achieve the school a good development, improve the level of application management key.

COMPUTER NETWORKS INFORMATION Local Area Network (LAN). Local area network is a computer network that connects computers and devices in a limited geographical area such as home, school, computer laboratory or office building. The defining characteristics of LANs, in contrast to wide area networks (WANs), include their usually higher data-transfer rates, smaller geographic area, and lack of a need for leased telecommunication lines.

Passive Optical Network (PON) is a form of fiber-optic access network that uses point-to-multipoint fiber to the premises in which unpowered optical splitters are used to enable a single optical fiber to serve multiple premises. A PON system consists of an OLT at the service provider's central office and a number of ONU units near end users, with an ODN between the OLT and ONU. PON reduces the amount of fiber and central office equipment required compared with point-to-point architectures.

GPON (Gigabit PON) is based on the TU-TG.984.x standard for the new generations of broadband passive optical access. Compared with the other PON standards, GPON provides the unprecedented high bandwidth downlink rate of up to 2.5 Gbit/s, the asymmetric features better adapt to the broadband data services market. It provides the QoS full business protection, at the same time carries ATM cells and (or) GEM frame, the good service level, the ability to support QoS assurance and service access. Carrying GEM frame, TDM traffic can be mapped to the GEM frame, 8kHz using a standard frame able to support TDM services. As a carrier-grade technology standards, GPON also provides access network level protection mechanism and full OAM functions. GPON is widely deployed in FTTH networks. It can develop into two directions which is 10 GPON and WDM-PON.
