10Gbe Networking Recomendations/Issues

[Zygizz]

Hello,

 We have Two houses they located close to each other so around 30m. Stretch cable ( 6a category ) between house thinking in future I gonna use cable to connected houses with 10gbe networking cable length ( 46 m. ).

 

I have bought two MikroTik CRS326-24G-2S+RM they have sfp+ port but sfp+ adapters only support 10gbe up to 30m ( and mine distance is 46m.)

 

Can I use MikroTik CRS312-4C+8XG-RM  Rj45 10gbe port from one side and MikroTik CRS326-24G-2S+RM with sfp+ adapter from another side to overcome this issue?

 

And I have to use this 6a cable.

 

Thanks in advance

i'd go CAT 7 cable as it has even better shielding for any kinds of interferences.

 

I don't really get your Switch logic here though.

You have to have an RJ45 10gbit capable switch in each house. The second one you stated only supports SFP+ 10gbit, so that doesn't work.

Generally i'd advice to go RJ45 based networking as it's just so much more convenient. Network cards are also getting cheaper every day.

 

Another thing you can try is two Asus XG-U2008 for example. you can get them used for as low as 130€

Do you HAVE TO use cat6a cable?  You can buy ready made fiber cable with connectors preinstalled on both ends and then all you need is a couple sfp+ transceivers which are cheap, around 20$ each.

 

Examples:

Amazon.com: 10GBase-SR SFP+ Transceiver, 10G 850nm MMF, up to 300 Meters, Compatible with Cisco SFP-10G-SR, Meraki MA-SFP-10GB-SR, Ubiquiti UF-MM-10G, Mikrotik, Netgear, D-Link, Supermicro, TP-Link and More.: Computers & Accessories

 

Amazon.com: 10GBASE-SR SFP+ Module for Cisco SFP-10G-SR, 10Gb/s Multi-Mode LC Transceiver, Up to 300m: Electronics

 

The two above are both duplex lc , so a cable like this would work:

Customised Length LC-LC UPC Duplex OM4 Multimode Fibre Patch Lead 2.0mm PVC (OFNR) - FS Germany

Customised Length LC-LC UPC Duplex OM3 Multimode Fibre Patch Lead 2.0mm PVC (OFNR) - FS Germany

 

2 pairs, 50 meters length in sleeve for exterior for around 100$ :

Customised 2 Fibres Indoor/Outdoor SM Pre-terminated Fibre Cable - FS Germany

Asus XG-U2008 is unmanaged switch and i need managed switches. I one house am only have sfp+ ports available in another i have switch with 10gbe rj45 ports.

I HAVE TO use cat6a cable because all holes used with wiring already closed and i can't open then again so am stuck with Cat6a cable only

Then another option would be media converters ... though they're somewhat expensive, at around 100-150$ each:

 

Unmanaged 1x 100M/1G/2.5G/5G/10GBase-T to 1x 10GBase-X SFP+ Slot 10Gigabit Ethernet Media Converter, European Plug standard - FS Germany

Unmanaged 1x 100M/1G/2.5G/5G/10GBase-T to 1x 10GBase-X SFP+ Slot 10Gigabit Ethernet Media Converter, British Plug Standard - FS Germany

 

plus a pair of cheap 1m DAC cables to connect the media converters to the switches.

So if i understand it correctly they going to work like signal booster ?

[mariushm]

They're media converters ... they convert fiber signal to 10g-base t (max 100 meters on cat6a) and backwards ... bi-directional.

 

Normally, they're used to convert the ethernet to fiber to carry the signal more than 100meters through fiber cable  - can be up to 40km depending on fiber type but 300m-2km is more common - but they can be used the other way, they don't care, they're bi-directional.

 

A 1m DAC cable would probably be cheapest (to connect to existing switches/routers) as cable has sfp+ connectors on both ends, alternative would be two transceivers plus a patch cord of fiber on each end.

I found these adapter that saying they working up to 80m i would be good solution in mine case
