In the early days of fiber optics, the biggest complaint was about the difficulty of installing connectors. You had to mix epoxy and inject it into the connector. Then you had to let the adhesive cure overnight or use a bulky curing oven.
Optical local area networks (OLAN) will cause you to rethink practically everything you have learned about LANs and LAN cabling. Of course, any major change in technology like this causes FUD (fear, uncertainty and doubt), just like voice-over Internet protocol (VoIP) and Wi-Fi have already.
