Your copper run to the server room or the back office is longer than it should be, and you need fiber without ripping out existing cabling. The MC220L bridges your RJ45 connection straight into single or multi-mode fiber. Multi-mode reaches 0.55km. Single-mode hits 10km. The FX port is hot-swappable, so you can swap transceivers without powering the unit down. Complies with IEEE 802.3ab and IEEE 802.3z. Plug it in, seat the SFP, and your link is live. Add to cart when you're ready to run that fibre
