Build better Local Area Networks with passive fibre technology

Build better Local Area Networks with passive fibre technology

With the wide-spread adoption of fibre technology, Passive Optical Networks (PON) are being used for more than just last-mile FTTx services. Until recently, ISP’s have left the major fibre roll-outs to larger infrastructure providers, creating a technology gap that was filled by PON, enabling ISP’s to no longer be dependent on the large infrastructure providers. EPON (Ethernet Passive Optical Network) and GPON (Gigabit Passive Optical Network) are popular versions of passive optical networks – it is no coincidence that this technology is fast becoming the go-to solution for all last-mile fibre connectivity.

“A Passive optical network makes use of ‘passive’ non-electrically powered splitters that can split one incoming fibre connection into multiple outgoing fibre connections.  EPON has a limitation of 1:64 connections per PON port, whereas GPON has a limitation of 1:128 connections per PON port.  OLT’s ( Optical Line Terminals), similar to a switch, can have multiple Ethernet connections as well as multiple PON ports, for example, a 4 PON port GPON OLT, can support up to 512 ONU connections.” Read more about PON

The major benefits for PON adoption include.

  1. Reduces risk due to less equipment deployed in the field
  2. Reduced installation times as a result of the reduced amount of materials in the field
  3. Reduced overheads meaning the cost to customer is greatly reduced

Introducing: POL or Passive Optical LAN.  

 

There is something to be learnt from the fibre providers in our country and around the world. Building a layer-2 network off a fibre backbone, allows you to expand your services and keep up with the demand without much maintenance on existing infrastructure. POL is no different from last-mile fibre connectivity, but it does provide a blueprint in building effective, long-lasting networks. By reducing overheads and time-to-install, service providers and network installers have the opportunity to reach more clients, build stronger networks, and ultimately create a more reputable name for themselves in the industry and with their customer base.

When looking at POL topology for a large building application, the number of PoE switches needed are greatly reduced as each floor is assigned its own passive splitter.  Each floor can run from a dedicated PON port, depending on the number of endpoints to be registered. Furthermore, considering the size of fibre cable, micro-blown installations result in a very neat and discreet install.

Should the need for more services arise, such as surveillance or IP phones, termination points (ONU) act as a fibre-to-copper converter, allowing you to run an entire camera or phone system, off of a single fibre strand. Now, management might be considered a nightmare, but with BDCOM’s NMS we are able to monitor, manage and maintain the network, from a single pane of glass. Read more about BDCOM’s NMS

BDCOM’s solutions complement cost effective EPON and GPON equipment for large-scale LAN deployments. So, when you are looking to build your next LAN, consider BDCOM, as it is a sure way to save costs on installation, materials and energy consumption, meaning you save money while offering more services to your customers.
