GS728TX and SFP Tranceiver
Our new ISP (optic fiber) will give us SFP hand off for our switch. I am thinking of buying GS728TX.
I understand that GS728TX supports SFP+, but does SFP tranceiver work with that model?
As they provide SFP, I am thiking several options, but I do not know which one works and which one dose not.
- 10Gb SFP+ swtich AND SFP+ Tranceiver
- 10Gb SFP+ switch AND SFP Tranceiver
- 1Gb SFP switch AND SFP Tranciever
According to some companies' exlanations, if I insert a SFP tranciver to SFP+ port, it works, but the speed is locked to 1Gbps. Does this mean that that mixed combination does not suport less speed than 1Gbps? Our Internt speed will be 500Mbps/500Mbps.
SFP is new to me. If I can hear any advices, I really apprecaite it.
Thank you very much.
There is nothing to worry about the link speed - the ISP will throttle the up- and downstream throughput as per the contract.
Technically, all three combinations are workable, SFP does always run on a 1G fiber link speed, SFP+ can operate on 10G and 1G fiber link speed on industry standard switches and routers.
Not sure what/how you intend to run your network. Typically, you terminate the Internet link on a router, which also does care about NAT for the private RFC1918 internal subnet (very unlikely they will assign you with a large block of public routeable IPv4 addresses due to IPv4 shortage), does firewall, mapping public IP form a small subnet to a server DMZ, ... The only reason for a switch on the wild Internet side would be if you are going to deploy a HA or clustered Internet security appliances.

Thank you very much. That is exactly what I wanted to confirm. Also, the reason why I need a swtich there is exactly what you guessed. We need HA, etc.
Again, I appreaciate your reply.
Thanks again.
