Jootoo Ethernet Switch 4-ports

This is a Gigabit 2 optical 4 electrical fiber optic transceiver switch, providing 4 1000Mbps and 2 Gigabit SFP optical ports. It can convert electrical port signals into optical port signals and perform long-distance data transmission through optical fiber. The SFP interface supports different SFP modules such as SC, LC, single-mode single fiber, single-mode dual fiber, and multi-mode dual fiber. Depending on the module, the transmission distance supports 3 kilometers, 20 kilometers, 40 kilometers, 80 kilometers, and 100 kilometers.
