A Pair of 1.25G/s Bidi Gigabit Single-Mode Fiber Ethernet Media Converter with 2PCS Bidi SFP LC Transceiver Module Included, 10/100/1000Base-Tx to 1000Base-SX SMF RJ45 to SFP Slot up to 30KM

You can also DIY it. https://www.reddit.com/r/homelab/comments/1sz9li4/invisible_bend_insensitive_bidi_fiber_is_amazing/ is a post where someone else did. He also posted another pic down in the comments showing it going around a corner. The specs listed for the InvisiLight fiber are technically better than G.657.A2, but I'm not sure how accurate they are. I bought some of the generic stuff for $15 to play with, but don't have any plans to buy the expensive InvisiLight kit just to look at it. https://www.amazon.com/dp/B0FBS7N1WH/ is 100m of G.657.A2 fiber with LC ends (smaller than the SC used by InvisiLight) for $22.https://www.amazon.com/dp/B08LDJ44XF/ is a pair of 1Gb media converters with bidirectional LC SFPs for $64. If you have the need/desire, you could also step up to 10Gb SFP+ media converters for more money, or use switches with SFP ports builtin. Other than the appearance, this stuff behaves just like any other standard fiber optic networking cable.

Get some of this Single Mode LC Fiber and some media converters with transceivers and you will be good.

Do not use cat 6 UTP along side the electrical feed. Use fiber for the run. Get the needed length of Single Mode LC Fiber and some media converters with transceivers and you will be good to go. I would run 2 lengths so that you have a spare in case......
