How PON Technology is Redefining The Modern Trends of Connectivity

The elimination of intermediaries is the basic challenge to defeat when it comes to amping up the connectivity. Data users need flawless AV experience and want to witness everything happening around the world, that too, on the gadget of their choice. PON technology has brought the miracle of fiber optic products right on to the lap of the users and they are experiencing an unmatchable enhancement in the quality and omnipresence of the network. Data communications and mobile networks have rose to their due fame because of PON that has made fiber connections an end-to-end proposition.
A passive optical network (PON) is an optical fiber cabling that reaches till end user point or at some intermediate position between the optical fiber source and the consumer point. On the basis of the destination where the passive optical network culminates, it can be classified as under:
FTTH: Fiber to the Home – A speedy ADSL line connects fiber networks to the customer devices directly, thus, a single Wi-Fi point can reach multiple devices eliminating the need of plenty of cables in the home interiors.
FTTC: Fiber to the Curb – A common network point which is an intermediate point between the source and the final end point is also a type of PON. This type of PON allows the end user to continue using their existing copper cables, thus, helping them enjoy faster data access at no additional cost.
FTTB: Fiber to the Building – PON brings the fiber connections to a building. Such arrangement is ideal for commercial premises where multiple devices are connected using splitters and combiners.
Basic Applications of PONs
PONs are the fiber networks that are able to deliver a high-quality signal to a short distance. Their main application is in digital content delivery through the audio-visual medium such as digital TV. These are also utilized for Voice over Internet Protocol, Internet services etc. The most common example of PON is a Wi-Fi connection point that delivers the internet connection to more than one device on a single hotspot.
PON also works as backend resource in distributed antenna systems (DAS), cellular enabled base stations. PON is certainly an advanced technology as the connectivity is not disrupted by any kind of loss caused due to electrical interfaces.
The best application of PON is that it can provide connectivity across multiple devices from a single point. Thus, it is easing out the operations of internet service providers who need not multiply their resources to meet the demands of increasing customer base. The PON allows the user to enable 1:16 to 1:128 network configuration ensuring easier installation and similar connectivity strength across multiple points.
Limitation of Passive Optical Networks
A PON is composed only of fiber and passive components. Since there is no active component involved, the signal reach is restricted to a limited distance, say 12 miles or 20kms. Passive components like multipliers, splitters and combiners constitute a PON that are mainly used in network connections reaching up to a small distance.
A typical PON network structure is resource efficient
 A point to multi-end user network comprising of a central OLT at the source delivering service to as many as 16 to 128 customers on a single fiber is what a typical PON looks like.

Thus, PON is creating scope for maximum resource utilization and optimizes the power consumption to the best benefits of the network providers. Thus, a connectivity solution preventing the duplication of resource consumption, seamless distribution of signal quality and equal but low-power strength of signals on individual end points, just like PON, has certainly transformed the concept of modern connectivity into a sophisticate module.
Evolution of PON in consonance with the growing requirements
The PON story started with BPON that was an ATM based arrangement. With ATM becoming obsolete, the broadband PON came into the picture that delivered 622 Mbits/s downstream and 155 Mbits/s upstream. Though this standard is acceptable at some transmission systems, but the major of the communications systems require speedier standards of content delivery as video experience and rampant downloading of data is creating demand for data transmission in gigabits, and thus, GPON is being recognized as the ideal connectivity solution for achieving video transmission of the highest quality.  The GPON is compatible with Ethernet, IP, TCP, UDP, T1/E1, video, VoIP, or other protocols of the data transmission. 
TV and internet service providers have to have an infrastructure that is cost-effective as well as relevant to the content demands of the present day users. Integration of internet, TV as well as VoIP phone into a single network has eased the networking intricacies to a great extent. Passive, till now, meant data transmission only to the limited area; but, with the betterment of the standards, distance issues have also been resolved to an appreciable extent. Multi-utility and compactness of the network are the two basic requirements of the present day communications systems; PON has provided perfect answer for these issues.
