Now to upgrade everything else
This was my first 100Gb transceiver for my home. I'm only running 10G at home so couldn't max it out here. I did drag it into the office and dropped it into a development server there and was able to verify that it is blazing fast. Now I just have to find spare cash to upgrade my home network. Do I need 100G at home? Nope. Do I want it? Of course!

Reliable Transceiver For Mission Critical Fibre Network Connections
We have started using these 100G QSFP28 multimode transceivers with our Cisco QSFP-100G-SR4-S units and we haven't looked back. The speed, reliability and functionality of this QSFPTEK transceiver is absolutely phenomenal. I highly recommend these 100G QSFP28 units for mission critical fibre network connections.
