3Com 3CSFP93-4500 Switch 4500 series Optical Transmission Module

The 3Com 3CSFP93-4500 is a 1000BASE-T SFP transceiver module built for the 3Com Switch 4500 series, providing a copper Gigabit Ethernet uplink option on switches whose SFP cages would otherwise only accept fibre optics. Using a standard RJ45 connector, this module lets network engineers extend Gigabit copper connectivity over standard Cat5e/Cat6 cabling up to 100 metres, which is useful where a fibre run isn’t available or where matching an existing copper infrastructure segment is preferable to a fibre uplink. As a hot-swappable SFP module it can be inserted or replaced without powering down the host switch, keeping planned maintenance windows short. This transceiver is specifically qualified for the 4500 family, so compatibility with other 3Com switch platforms using different SFP validation firmware isn’t guaranteed. Genuine modules of this type remain a routine requirement for maintaining full port capacity, restoring redundancy after a failed uplink, or expanding an existing 4500-series deployment still in active service. Specifiers should confirm exact host-switch compatibility before ordering. Tech-Star (UK-based, shipped worldwide) stocks tested components to support ongoing network maintenance projects.
