I know a few basics on networking but have zero experience using transceivers with Fiber)
My home network is currently using 1Gbs ethernet backhaul. I want to upgrade to 10Gbs fiber so I purchased two 10Gbs capable Mikrotik Switches/routers. (Mikrotik CRS326-24S+2Q+RM, Mikrotik CRS305-1G-4S). I also purchased an assortment of transceivers, fiber and DAC cables that appear to be compatible.
- Compatible MikroTik S+85DLC03D SFP+ 10G SR 300M Optical Transceiver module (worked on both Mikrotik devices),
- E10GBFSR Intel Compatible SFP+ 10G SR Transceiver module FTLX8571D3BCV-IT (note: this one only worked when on 24 port Mikrotik switch while 4-Port was using above transceiver)
- MikroTik XS+DA0003 SFP/SFP+/SFP28 direct attach cable, 3m
- Compatible Mikrotik S+AO0005 5m SFP+ 10Gbps Active Optics direct attach cable
- AmazonBasics 10Gb 40Gb Multimode OM3 Duplex 50/125 OFNP Fiber Patch Cable LC to LC - 1 Meter
- 10G 2m SFP+ DAC Cable - 10GBASE-CU Passive Direct Attach Copper Twinax SFP Cable for Cisco SFP-H10GB-CU2M, Ubiquiti, D-Link, Supermicro, Netgear, Mikrotik, ZTE Devices, 2m
- 10G 5m SFP+ DAC Cable - 10GBASE-CU Passive Direct Attach Copper Twinax SFP Cable for Cisco SFP-H10GB-CU5M, Ubiquiti, D-Link, Supermicro, Netgear, Mikrotik, ZTE Devices, 5m
I assume compatibility because I can connect to the Internet when I connect my laptop (1GB/s) to 24port Mikrotik (using auxiliary port on bottom right). In turn the 24 port is connected from port1 to port 1 on 4-port using 10GBb/s DAC cable, which in turn is plugged into my current home router at 1Gbs (using 10Gbs transceiver and cat6 in forth port of 4-port Mikrotik). Or in other words data travels like this:
laptop LAN port > 24 port Mikrotik > 4 port Mikrotik > home wifi/router > internet
I have no problem connecting. The problem arises when I try to speed test using Mikrotik's built in switch-to-switch testing tool (found under tools). Although the two Mikrotik switches are connected using 10Gbs DAC cable (also tried using Mikrotik compatible 10Gbs transceivers and fiber) when I test the connection just between the two switches it caps out at just under 1Gbs no matter what combination of 10Gbs connecters I use.
