An SFP transceiver is a device that plugs into an SFP port on your network switch and allows it to communicate via Ethernet over a fibre cable. The type of transceiver you select will vary depending on the distance and fibre cabling infrastructure you require. In addition, many switch vendors require that transceivers are “coded” to enable them to work. 4Cabling has a huge range of SFP Transceivers & 3rd Party SFP Transceivers that are well priced & in stock.
