The USW-2203-SFP is a rugged, fanless, industrial-grade, 3-port unmanaged Gigabit Ethernet switch to fiber optic media converter that provides one channel for media conversion between 10/100/1000M Ethernet and 1000M fiber optic links (via SFP modules). The USW-2203-SFP works in pair (point to point) and it runs on a light-speed fiber backbone inherently resistant to radio and electrical interference, such as EMI/RFI, transient surges, and ground loops. Depending on the fiber cable and the type of SFP module used, a single-mode media converter can extend the 10/100/1000M Ethernet's distance to 12.4/25/37/50/62/75/100 miles (or 20/40/60/80/100/120/160 km), while a multi-mode media converter can extend the 10/100/1000M Ethernet's distance to 0.3 miles (0.55 km). The USW-2203-SFP is a plug and play unit featuring auto-negotiation for 10, 100 or 1000M data rates, it also supports MDI (straight-through) and MDI-X (auto-crossover), no DIP switch or jumper settings are required.
