Discussion about fiber cables
I am upgrading my house to 10 gigabit connections (because i feel like it) on my computers and learning on the fly. I have bought everything off eBay and amazon but now realize i may have a problem... or not i dono stuff is still in the mail CISCO WS-C2960S-48LPS-L CATALYST 48 PORT PoE+ SWITCH Intel EXPX9501AFXSR 10GbE XF SR Server Adapter x2 10GBase-SR SFP+ Transceiver, 10G 850nm MMF x2 So the NIC and SPF are SR which i didn't notice till this morning will those work with the switch? Also i didn't know there was a difference in cables (SR and LR) so i grabbed 1x 3ft multi mode cable for the switch to the NAS but i grabbed a 50ft single mode cable for the switch to my main computer. Do i need to get a multi mode cable to replace the 50ft one or will a single mode cable work in a multi mode connection?
I handle it all in single mode myself. That’s not the same as SPF+, you probably don’t need it—I’m likely getting something like a X520 or connecting X3 instead. I’ll grab the LRR transceivers and switch to full singlemode. It should be noisy and power-hungry.
There are numerous 10g specifications available. XR connects differently from SFP+, meaning your adapters won't function properly. It's also an older electrical standard, making it difficult to locate compatible components, and software support is likely discontinued for newer devices.
Review those suggestions I made before? Connect x3 and x520. For other cards, search online to find what users experience with them on FreeBSD.
The device lacks 10gbps connections; it features four SFP ports with a top speed of 1 gbps each. That makes it somewhat redundant... You can still utilize the 48 ports at 1 gbps, but it's not worth the energy consumption for a gigabit device. You might prefer a simpler non-administrative switch instead. I recommend a basic 5-port switch supporting 10gbe with four SFP+ ports and one gigabit RJ45 port, priced around $150 or less. The chipset options aren't ideal unless you're already aware of the issues. You'd need XR ports to accommodate those cards. SFP+ modules are affordable, starting around $35... Check out the Solarflare models here: links provided. The cards mentioned are questionable, as they require compatible hardware. You'd also need a switch with XR ports if you plan to use them. Fortunately, SFP+ cards are reasonably priced at about $35 and higher. You can also explore Solarflare products on eBay, and the store link I shared includes an eBay section.
The solarflare cards rely on standard and popular Intel components along with Broadcom chipsets, ensuring compatibility.
