The Bel gigabit copper Small Form-factor Pluggable (SFP) transceiver is a hot-pluggable module with RJ45 interface supporting 10/100/1000BASE-T operation over CAT5/5E cables, built to the SFP Transceiver Multi-Source Agreement (MSA) for installation in standard SFP ports on switches, routers, and other networking equipment. Engineered to deliver data rates that rival fiber-optic links while running over installed copper cabling, the module lets network designers avoid the cost and disruption of pulling new cable. It is suited for enterprise networking, data center, and industrial automation deployments where equipment provides SFP cages but endpoints and cabling remain copper.
