Transceiver

Overview

Transceiver - the equipment that connects fiber cables to switches. It contains a laser that provides the light signal for data transmission. Erroneously called GBIC often times (this was an older and proprietary Cisco version), or SFP or SFP+ (plus) adapter. Some switches can use SFP28, SPF56, or QSFP. They are all types of transceiver but vary in speed or distance the laser can reach.
