transceiver

My main switch (MikroTik CRS309-1G-8S+IN) is running very hot with 3 10GBASE-T SFP+ transceivers (even spaced in non-agacent ports). I did the popular fan mod but it was loud and only kept the closest port cool. I have a 10GBASE-T NAS, a 2.5GBASE-T WiFi Router (Multiple VLANS--untagged so it...

tl;dr - I'm trying to connect a ConnectX-4 MCX4131A-BCAT to a ConnectX-3 MCX354A at 40GbE. My Kaiam XQX2502's only seem to negotiate 1GbE. Is there a transceiver that will get me back to 40Gbps? Previously, I had two ConnectX-3 MCX354A's connected (Windows to Linux) with Kaiam XQX2502's linked...

[EDIT] After 2+ more hours I think I have found an answer. Nope. Every article I see talks about compatibility of using older 40Gbit QSFP+ optics in 100Gbit QSFP28 switches. Does the opposite work? I doubt it, but it would be good to know. I'm on a shoestring budget and I'm encountering...

Hi, I'm trying to setup my Atista 7050s52 but failing somewhere. I gave an ip to the managemrnt console and can ssh into it. I'd like to connect it to say port 48 to get it reachable from other port(s). OR to setup vlan interface(s) with ip to make the switch reachable from those ports. Now...

Hello STH. I'm just getting started with a home server and hit a stumbling block that I could do some help with. I bought some mismatched 10G nics for peer to peer over DAC between my r720 server and clients. Works fine. Now I need more distance so want to try fibre so bought another chelsio...

Hi I will be getting some servers soon and they are equipped with HP 560FLR 10gb NIC I would like to know if the HP nics are forgiving in terms of transceivers or I must use HP transceivers I am asking because I see some Cisco transceivers for really cheap on eBay and was thnking maybe I can...

Probably noob question: Do all SFP+ NIC accept Fiber Transceivers? I want to buy a few 10G NICs and use a fiber SR Transceiver. Saw the threads on the OEM Mellanox, but couldn't figure out if they use copper or Fiber transceivers.

Hi everybody, I need to setup a 40G network, I am connecting a single workstation with a server. As of right now, I only need point-to-point between these two machines. Distance is app. 15m. Been reading up on 40G required hardware, but am a little bit confused, so I have some questions -...

I can get some 4x16bit QSFP transceivers for free, however from my understanding these are originally intended for FC. Does the link protocol really matter? Isn't it just a physical conversion layer and as long as the transfer bitrate keeps up I could use these for QDR Infiniband or do I really...
