<p class="MsoNormal">Could you use a transceiver for the 1000Base-T? copper <-> fiber <-> copper that will create an ‘air gap’ on the data circuit. You still run the risk of a lightning strike entering through the transceiver power. You could filter that

<p class="MsoNormal">I'm working with a client site that has been hit twice, very close by lightening.

<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I did lots of electrical work/upgrades/grounding but now I want to focus on protecting Ethernet connections between core switching/other devices that can't be migrated to fiber optic.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I was looking for surge protection devices for Ethernet but have never shopped for anything like this before. Was wondering if anyone has deployed a solution?<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">They don't have a large presence on site (I have been moving all of their core stuff to AWS) but they still have core networking / connectivity and PoE cameras / APs around the property.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Since migrating their onsite servers/infra to the cloud, now their connectivity is even more important.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">This is a small site, maybe about 200 switch ports, but I would only need to protect maybe 12 core ones. but would be something I could use in the future with larger deployments.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">it's just a 1Gbe network BTW.<o:p></o:p></p>

<p class="MsoNormal">Hope someone with more experience can help make hardware recommendations?<o:p></o:p></p>
