A PON technology based on Ethernet. EPON is currently a part of the Ethernet standard. Physical reach is defined as the maximum physical distance that can be achieved for a particular transmission system. The official number of [G. Specifically, GPON system must have a maximum mean signal transfer delay time of less than1. The splitters are designated as [n: The larger the diameter of the telephone, the longer the distance it could reach.

A product by EFM Ethernet in the first mile. PMD generates electrical or optical signals depending on the nature of the physical medium connected. The transmission rate depends on the diameter of the telephone wire.

Fiber offers a number of advantages over the previous technologies Copper. PMD is responsible for the interface to the transmission medium. Ethernet over point-to-point P2P fiber and over a network operating mechanism, Administration and Maintenance OAM to facilitate network operation and troubleshooting.


For this, it uses synchronized handboko at each end of the transmission line; resultantly, each signal appears on the line only a fraction of time in an alternating pattern.

FTTH – Quick Guide

The downstream transmission, i. PON system may be either symmetrical or asymmetrical. There is a complexity of using colored optical transceivers, which processing service is provisioning and devising storage.

Each upstream frame contains a number of transmission bursts coming from one or more ONUs. It has constant-size HEC-protected header. The following table lists the advanced services that can be provided through FTTH along with their bandwidth.

For example — Video at a different wavelength. PMD is optionally combined with management features that can be accessed via the management interface. It is the interface between PMD and the physical media.

It appears as a single entity for the purpose of upstream bandwidth assignment on the PON. This combination of the two; together makes the ONT the most cost effective solution to provide GPON services to local and single-family, small, and medium enterprises.

Very high bit rate digital subscriber loop VDSL supports a maximum bit rate of 55 bps. Constant length frames facilitate QoS for time-sensitive applications.


Downstream wavelength of nm is selected by FSAN. For the access of network technologies, there are normally two ways i. Fixed and the second is the Wireless way. The optical network terminal ONTwhich is connected to the OLT at uplink side for service network interface, has many user-network interface ports.

MAC control protocol was specified to support and new functions to be implemented and added to the standard at the same time.

The TV signals derived from a satellite Head End are optionally broadcast on a third optical wavelength of nm on same or additional fiber introduced into the FTTx system through an RF Overlay sub-system. It allows the exchange of IEEE PON Core shell consists of two parts. In GPON, the maximum differential fiber distance is 20 kms. The multipoint MAC control functionality 2100 implemented to access devices of the subscriber containing physical layer devices point to multipoint.
