It is an OPTICAL NETWORK TERMINAL, which serves to convert light to data and vice versa, in other words it serves as a modem for optic fibre.

Yes, but it can only be moved by an authorised MetroFibre technician - additional costs apply. The yellow fly lead used between the access point and the ONT is also extremely fragile, since it is basically constructed from glass . Pets, toddlers and vacuum cleaners are the biggest threats to fly leads. The lead should never be rolled up tightly, bent, or fixed to walls or skirtings with electrical cable saddles.

No, we do not shape or throttle our customers’ service in any way. Every ONT is configured exactly the same

Yes, although there has been no need to enforce it thus far, MetroFibre does reserve the right, and will take whatever steps MFN deems necessary, to prevent improper or excessive usage of the service. For more details please see Annexure 2 to our Terms and Conditions.

Broadband light: This indicates the status of the fibre link

  • Solid green – Fibre connection is active.
  • Flashing green – There may be a minor issue on the fibre link => Notify MFN or your ISP.
  • Red – High signal loss => Notify your ISP.
  • Off – Link disconnected => Notify your ISP.

Service light – Refers to your internet access

Speed & Connectivity

On a GPON network bandwidth is shared. You are only ever competing with a maximum of 64 people, so you should always get very close to your full speed, even if all other people are using the network at the same time. The important thing to note though is whether or not you are connecting to the ONT wirelessly or via network cable. A wired connection will always outperform a wireless connection. To get the best speeds, connect all possible devices using a network cable. If you choose to utilise wireless you will generally get a degraded speed. Wireless is affected by numerous environmental factors that we cannot control.

Wi-Fi signals experience attenuation due to distance from their source just like any other radio. This signal attenuation subsequently causes the radio to be less effective and throughput suffers. Eventually, connectivity is lost when the signal becomes too weak. There are essentially two factors that affect signal attenuation between the access point and the client, and those are range (or distance), and attenuation due to obstructions
