Wired & Wireless Networking

image

Network Infrastructure is a framework for the specification of a network's physical components and their functional organization and configuration. At Neps Technologies Pvt. Ltd, we understand the importance of building a comprehensive computer communications network. Our strategy is to utilize a layered approach or structure consistent with the Open System Interconnection (OSI) model. A key consideration to any infrastructure design is to ensure open standards-based solution set. At Alliance Technology Group we listen to our customer requirements and design solutions that meet their specific needs. By providing a vast array of solutions we ensure our customers are not committed to a particular manufacture or product set. Our solutions cover the following components:

•  LAN/WAN Design
•  Data Center/Core Networking
•  Wireless LAN
•  Wired LAN Solutions
•  VoIP
•  Quality of Service (QoS)
•  Routing
•  Switching and Distribution
•  VPN
•  Firewall

CCTV (closed-circuit television) is a TV system in which signals are not publicly distributed but are monitored, primarily for surveillance and security purposes. CCTV is commonly used for a variety of purposes, including: ?Maintaining perimeter security in medium- to high-secure areas and installations. ?Observing behavior of incarcerated inmates and potentially dangerous patients in medical facilities. ?Traffic monitoring. ?Overseeing locations that would be hazardous to a human, for example, highly radioactive or toxic industrial environments. ?Building and grounds security. City Surveillance Obtaining a visual record of activities in situations where it is necessary to maintain proper security or access controls (for example, in a diamond cutting or sorting operation; in banks, casinos, or airports). CCTV is finding increasing use in law-enforcement, for everything from traffic observation (and automated ticketing) to observation of high-crime areas or neighborhoods. Such use of CCTV technology has fueled privacy concerns in many parts of the world, particularly in those areas in the UK and Europe where it has become a routine part of police procedure.

Access Control Solutions (Card/Biometric based):

Access control systems provide exclusive security by providing access only to authorized personnel to enter & leave the premises. These access control solutions are based on Biometrics, Smartcards, RFID Tags... etc thereby making the system more reliable & fool proof. Intrusion Detection and Alarm Systems: Intrusion Detection Solutions are expert solutions that are designed to detect intrusions Securityin the perimeter level. This solution utilizes a specialized array of infrared sensors & motion sensors to detect intrusion accurately. The electrical fencing which can be clubbed with this offers more security by preventing the intruders to enter the premises. Day night cameras which are installed throughout the perimeter will add further value to this solution by monitoring activities around the perimeter. All these can be linked to a control centre which can be used to monitor & raise alarms whenever an intrusion happens.

FTTH

For the access of network technologies, there are normally two ways i.e. Fixed and the second is the Wireless way. In this tutorial, we will discuss the ‘Fixed’ method, technically called as the FTTH Technology.

 

What is FTTH?

Fiber to the Home or simply FTTH is a technology that uses optical fiber directly from the central point to the residential premises (as shown in the following image). It provides uninterrupted high-speed internet service. Here, “H” includes both home and small business.
 
Neptech FTTH 01
 
FTTH is the ultimate fiber access solution where each subscriber is connected to an optical fiber. The deployment options discussed in this tutorial are based on a complete optical fiber path from the Optical Line Termination (OLT) right to the subscriber premises.
 
This choice facilitates high bandwidth services and content to each customer and ensures maximum bandwidth for future demands of new services. Therefore, Hybrid options involving ‘part’ fiber and ‘part’ copper infrastructure networks are not included.

 

As an access to the home over fiber, Fiber to The Home (FTTH) scenario is mainly for the single family unit (SFU), providing a comparatively small number of ports, including the following types — POTS, 10/100/1000 BASE-T, and RF (18dBmV).
 

Optical Fiber Method can be deployed in two ways: Active Method and Passive Method. The current mass FTTH deployment is based on the passive method. Hence, let’s discuss the Passive Method in detail.
 
Passive Method − The two typical technologies used in this method are Ethernet Passive Optical Network (EPON) & Gigabit-capable Passive Optical Networks (GPON). Refer the following image.
 
 
Very high bit rate digital subscriber loop (VDSL) supports a maximum bit rate of 55 bps. VDSL2 has better QoS and better SNR.
ADSL (asymmetric digital subscriber line) supports a maximum bit rate of 8Mbps, however ADSL2 can go up to 12Mbps.
SHDSL stands for symmetric high bit rate digital subscriber line. The larger the diameter of the telephone, the longer the distance it could reach. The transmission rate depends on the diameter of the telephone wire.
Integrated service digital network (ISDN) is based on circuit-switched network
.
Why FTTH?
Fiber offers a number of advantages over the previous technologies (Copper). The most important ones are as follows −
Enormous information carrying capacity
Easily upgradeable
Easy to install
Allows fully symmetric services
Reduces operations and maintenance costs
Covers very long distances
Strong, flexible, and reliable
Allows small diameter and lightweight cables
Safe and secure
Immune to electromagnetic interference (EMI)
Lower cost
The following table lists the advanced services that can be provided through FTTH along with their bandwidth.
