GPON/Passive Optical LAN

GPON/Passive Optical LAN

POL or GPON is a point-to-multi point access mechanism of distribution enabling a single feeding fibre to multiple desktops and connection points.

Here's the more cost effective and energy efficient alternative to traditional network architectures.

POL uses a single-mode fiber extended closer to the user and electronic devices eliminating distance constraints, reducing the quantity of cables and related installation costs.

"Split" and share a single fibre connection for immediate cost benefits.

Gigabyte Passive Optical Network, known as GPON, rely on fiber optic cables to deliver video, data and voice signals. GPON networks are currently the leading form of Passive Optical Networks (PONs), and offer up to a 1:64 ratio on a single optical fiber, meaning, a single fiber from the OLT can deliver video, data and voice signals to up to 64 end users (or residences). Simple and immediate benefits include;

  • Cost savings
  • Energy efficient
  • Easy install and maintain
  • Eliminates need for telecommunications rooms
  • Simplifies network moves, adds and changes
  • Increased security

The basis of GPON is that a single fibre connection to the local exchange can be “split” and shared between multiple end customers. It achieves this with a passive (not electrically powered) optical splitter in a junction box, usually in the pavement/road manhole around a cluster of potential end customers. Think of this main fibre link from the exchange to the splitter as a “trunk line” to a desk, celing or adjacent building.

POL is a more cost effective and energy efficient alternative. POL uses a different architecture with single-mode fiber extended closer to the user and electronic devices that flatten the Local Area Network, eliminating distance constraints and reducing the quantity of cable to the workstations.

A POL consists of an optical line terminal (OLT), an optical splitter, and optical network terminals (ONTs) to transmit voice. Additionally, since the ONTs can support multiple devices, Passive Optical LANs require less cable (and the labor to install it) to support the network.
