The Ethernet services are presented in different ways depending on the link speed you have requested. ===100Mb/s=== For 100Mbit/s links (and below) the service is presented using a normal Ethernet (copper) RJ45 connector. You use a normal cat-5 Ethernet patch lead to connect this to your switch, router or firewall as you required. IMPORTANT the ~~link~~port on the Openreach supplied unit is sometimes configured as fixed full duplex. This means that if it is connected to an un-managed switch or un-configured port on a switch, router or firewall then it will not work correctly. It will seem to work, but as soon as any reasonable level of traffic flows there will be dropped packets seriously hindering upload speeds. You must have a managed switch or port connected to the link and configure the port to be fixed full duplex 100Mbit/s for it to work correctly. We can supply a small managed switch for this purpose if you require. Cabling is a straight through cat5e patch lead to your managed switch. ===1Gb/s=== 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. This link should be used with an auto-negotiation port which is the default for gigabit links SFP-SX.jpg\|SX SFP for customer equipment MMF.jpg\|Multimode patch lead Adva-closeup.png\|Close up </gallery> ===10Gb/s=== For 10Gbit/s you will need special 10Gbit/s equipment, contact sales when ordering for details.
