What Is Passive Optical Network?
Passive Optical Network (PON) is a form of a 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.

The most obvious advantage of the PON network is the elimination of outdoor active devices. All the signals processing functions are completed in the switches and the user premises equipment. The upfront investment of this access methods are small, and the most funds investment is postponed until the user really access. Its transmission distance is shorter than the active optical access system. The coverage is also smaller, but it is low cost, no need to set the engine room, and easy to maintain. So this structure can be economically served for the home users.

IET designs and implements Passive Optical Network (PON) solutions for commercial and government customers seeking the latest innovations to reduce IT costs.  As a CommScope Premier Business Partner, IET is able to bring this innovation to new and existing IT networks with “end-to-end” fiber to the X (FTTX) architectures. IET also partners with Tellabs to provide Optical LAN to deliver the latest in all fiber solutions.  IET is able to offer an extensive set of fiber products and PON solutions to give network owners and operators the ability to transmit voice, video, and data using RFoG, EPON and GPON technologies at saving up to 70% of CapEx, 80% of power requirements and 90% of space requirements.

PON delivers voice, data, and video at higher terabit speeds with lower costs and greater security. Using the same technology as telecommunication carriers to deliver hi-definition television to homes and businesses, PON can benefit customers with less cost to install and maintain, greater capacity, less energy usage, and fewer space requirements. For government customers, PON also provides a higher level of security satisfying SIPRNet and SCIF requirements. CommScope’s EPON solution is DISA JITC (Joint Interoperability Test Command) certified in August 2013 enabling CommScope’s EPON solution to be approved for use in the U.S. Department of Defense networks.e energy
