A fiber optic splitter, is a passive device use in telecommunication networks. I'm planning to use a TP-Link MC220L transceiver to convert the optical signal to ethernet. This ethernet will then go through a 1 Gbit/s switch, and rout two ethernet cables to each floor. Unlike active devices (which require power), splitters operate without electricity, relying solely on the physics of. I'm struggling with scenario where I need split single WAN connection (6 public addresses available (/29)) between 2 seperate networks. 08-08-2018 02:55 PM It depends. Is your default gateway. In principle, an optical cable can be split, but it's not as simple as just cutting the cable and attaching multiple devices.
