The TRANSITION NETWORKS S3221-1040-T-UK is an Ethernet media converter that bridges a copper 10/100/1000BASE-T network connection to two SFP (Small Form-factor Pluggable) fiber or copper uplink ports. Designed for enterprise network infrastructure, this unit enables flexible media conversion between twisted-pair copper cabling and SFP-based links, supporting data rates from 10 Mbps through 1000 Mbps (Gigabit Ethernet). Network technicians deploy this converter where copper-to-fiber or copper-to-SFP transitions are required at the edge of a network segment or within a wiring closet environment.
This media converter is suited for enterprise LAN deployments where extending a copper Ethernet run over fiber is necessary, or where dual SFP uplink flexibility is required. Typical installations include structured cabling upgrades, data center edge connections, and campus network expansions. The unit is sold individually and is classified as an enterprise PoE device category product per supplier documentation.
Designed as an OEM-style media converter for enterprise network infrastructure requiring copper 10/100/1000BASE-T to SFP media conversion. Compatible SFP modules are not included and must be sourced separately based on application requirements.
Installation should be performed by a qualified network technician familiar with structured cabling standards and enterprise LAN practices. Power down or disconnect the host network equipment before connecting or disconnecting SFP modules to avoid damage to the transceiver or converter. Follow applicable TIA/EIA cabling standards and the equipment manufacturer guidelines when routing fiber or copper patch cables to the SFP ports. Do not force SFP modules into slots; verify module type and keying before seating.
