GPON, what is it and why install it?

A Gigabit Passive Optical Network (GPON) is a point-to-multipoint, fiber to the premises network architecture in which unpowered optical splitters are used to enable a single strand of fiber to serve multiple premises, typically 16 to 128. A PON consists of an optical line terminal at the service provider's central office and a number of optical fiber network units near end users. A PON reduces the amount of fiber and central office equipment required compared with point-to-point architectures. A passive optical network is a form of fiber-optic access network.

Downstream signals are broadcast to all premises sharing multiple fibers. Encryption can prevent eavesdropping.

Let's take a quick look at why you'd install GPON. This Tellabs Passive Optical LAN video using GPON technology at the Department of Energy Sandia Lab in New Mexico gives us a good feel for the benefits.

Looks like it's time to redesign the network again. Maybe for the last time.
