When Planning a Local Area Network (LAN), the system administrator or the IT team, needs to pay attention on various aspects. First, they must stay up-to-date technologically, in terms of network speed, capacity and functionality. At the same time, they have to control both upfront and long-term LAN costs. Finally, they have to figure out a way to achieve those objectives while also complying with a global mandate to trim energy consumption. To list it down briefly, they need to keep the following things in mind while planning out the network:

  • Scalability
  • Availability
  • Redundancy
  • Manageability
  • Security
  • Convergence
  • Interoperability
  • Intelligence
  • Future safe investment
  • Green technology
  • Penta-play capable (data, voice, video (Cable TV, surveillance & video communication), building automation & wireless
  • Low CAPEX and
  • Low OPEX

That’s a tall order. But customers can now achieve these goals by deploying an advanced GEPON solution, based on gigabit Ethernet passive optical networking (GEPON) technology. The solution delivers a “70-80-90” set of benefits: reduce capital costs by up to 70%, reduced power consumption by up to 80%, and shrink the required floor, rack and closet space by up to 90%.

In the past, all GEPON solutions were created for the residential market for FTTH networks by service providers. However, now ZyXEL’s R&D and customization of the technology to suite the need of campus network, today we are using the same technology not just for FTTH, but for FTTB (Fiber-to-the-building), FTTF (Fiber-to-the-Floor) and even FTTN(Fiberto-the-node). The ZyXEL GEPON solution is being widely used to today even in the campus wide networks, which was conventionally deployed purely on a switching solution.

An GEPON is a Layer-2 transport medium, built with PON technology and fiber-optic cabling, which provides converged video, data and voice services at gigabit speeds over a single strand of fiber to endusers. Compared with legacy active-Ethernet solutions, a GEPON dramatically reduces electronics and cabling requirements. The PON cabling infrastructure supports bandwidth of more than 50 terabits per second (Tbps), and the single-mode fiber extends the LAN reach up to 20 kilometers without signal regeneration.
