Is 8-Channel HD-SDI & 10/100 Fast Ethernet Transmitter and Receiver Kit was upgradable to 1Gb instead of 100M?

We have a Thor 8-Channel HD-SDI & 10/100 Fast Ethernet Transmitter and Receiver Kit and we were wondering if it was upgradable to 1Gb instead of 100M

These units use TDM which has a maximum threshold of HD-SDI or 1.485Gbps along with max ethernet of 10/100. If you need Gigabit ethernet then you'd have to purchase separate units like this https://thorbroadcast.com/product/10-100-1000-mbps-fast-and-gigabit-ethernet-over-1-fiber-media-8230.html  Otherwise there is no upgrade option because the only way to do 3G-SDI or Gigabit is to send it over CWDM which is different, more expensive multiplexing technology, but utilizes a laser per input, then those inputs are muxed. The TDM unit you have means the signals are muxed then sent out through a single optic in time. Let me know if you have any other questions about this gear. 

This particular unit uses TDM Multiplexing and it has limited bandwidth available per the Time slot, this is why the 10/100 Ethernet is maximum we can do.
Although we have different devices that use CWDM optical multiplexing, each signal has it own optical laser so the no bandwidth limitation like in TDM multiplexing.
This is the link to the device, we can do any signal combination 3GSDI and Gigabit ethernet.
