The Ethernet services are presented in different ways depending on the link speed you have requested.

For 1Gbit/s bearers, the connection from the Openreach NTE to the customer equipment is presented using multimode mode fibre on LC connectors. A suitable SFP for the customer equipment would be a 550m MMF 850nm SX SFP and a length of multimode cable with LC connectors at each end. your router/switch would also need a SFP port. We can supply a suitable SFP and cable if you require.

The Openreach NTE does have a copper RJ45 port as well as an SFP port for connection to the customer router - however, the copper port is disabled by Openreach and the fibre port should be used.

For 10Gb/s you will need special 10Gb/s equipment, contact sales when ordering for details.▼

In most cases, it is possible to replace the Openreach supplied SFP with something different, eg a DAC cable, this may light an error LED on the Openreach box though, and so cause confusion in the event of a fault. We'd also require that the Openreach supplied SFP is used in the event of a fault report.
The ONT requires power, and has two IEC sockets for resilience. eg, you can use a UPS on the 2nd power socket to power the unit in the event of mains power loss.

Where there is more than one service on the link then all of the services will have a VLAN tag. This is used to
Where there is only one service on the link then this can be set to operate with no VLAN tag.
