Where to buy SFP+ cables?

[Elijah Kamski]

Hi there,

I want to set up a better home network but could never find where I can buy SFP+ cables, and I don't mean the 1M cables etc, I mean cables that can go across an entire house and stuff.

Location: Aus

Thanks,
Eli

My company buys most of its SFP cables/modules from Molex. You can try there but their website usually just outsources to other vendors for their products. Another company we use is Innolite. I've found a product that i believe fits your request, but more research into their compatibility would have to be done:

Are you planning to use cat6 cable ? The Alternative is optical cable SFP cables which will reduce the latency for your networking which might be needed if you want to do anything like what linus is doing.

For long distances you will want to buy the SFP transceiver and separate optical cables that you can carefully run across the home. In general however if you are not going past 10gbe CAT6 or CAT6A would suffice

I dont know why i'm surprised Amazon has this stuff but i never thought to look on amazon for optical cables and modules. Good to know lol.

fs.com  will sell you custom lengths of fiber and also fixed lengths. 

You buy the fiber with some standard terminals  like for example LC duplex, and then you buy separate transceivers for the socket you have (ex SFP for 1 gbps, SFP+ for 10g, QSFP for 40 gbps, SFP28 for 10/25 gbps.

OR you buy wallplates in which you then plug a DAC cable or a smaller fiber cable between the wall and a switch or a computer. 

 

For example: 

SFP+ 10 gbps transceivers (this one uses LC Duplex connector, for use with multimode fiber, OM3 or better, 300m+) : https://www.fs.com/de-en/products/11552.html

(you can get used ones / old datacenter stock for cheaper, for example: https://unixsurplus.com/finisar-ftlx8571d3bcl/ )

 

SFP28 25gbps transceiver using LC Duplex  (70m on OM3 , 100m on OM4 multimode fiber) : https://www.fs.com/de-en/products/67991.html

QSFP  40 gbps (4 x 10.5gbps) using MTP/MPO-12 fiber , 100m on OM3, 150m on OM4 fiber) : https://www.fs.com/de-en/products/36157.html

QSFP28 100gbps using MTP/MP0-12 fiber   : https://www.fs.com/de-en/products/48354.html

 

The newer standard is SFP28 and QSFP28  ... if you don't mind limiting yourself to 25gbps in the future, you'd be fine with regular cheaper fiber and LC duplex connectors (or you can have cables with 4 or more such fibers and do port trunking to get more than 25 gbps)

But if you want sort of future proof, you would want to go with MTP/MPO-12 fiber cables which are a bit more expensive.

 

You can get cheap (relatively) switches with SFP+ and QSFP ports,  switches with SFP28 and QSFP28 are still quite expensive. 

For example 

$419 for 32 x 40g QSFP+ ports : Quanta T5032-LY6 32X 40GBE QSFP+ Ethernet Switch 32G ONIE Open Network Linux PPC : https://unixsurplus.com/quanta-t5032-ly6-switch/

 

edit:  note for the above, you can buy QSFP+ to 4 x SFP+ breakout cable (5m) for 100$ , which is kinda cheap : https://unixsurplus.com/arista-qsfp-40g-sr4-40g-network-cable/

 

or shorter 2 meter breakout cable (includes transceivers) for $89 : https://unixsurplus.com/unixplus-breakout-cable-2-meter/

 

edit: or 69$ for qsfp to 4 x sfp+ dac cable (includes transceivers, 5 meters ) : https://unixsurplus.com/amphenol-emc-qsfp-4sfp10g-05mdac-cable/

 

also $79 for  a 10-pack of 3M DAC cables  (10 gbps SFP+), at 8$ each cable it's cheap : https://unixsurplus.com/cisco-CBL-SFP-SFP-10GB-DAC-OEM-MOLEX-3M/

 

 

Network cards are cheap as well, here's some from 65$ and up 

65$ 2x10g SFP+ Solarflare sfn7501 s7120 sfc9120 2-Port 10GbE SFP+ PCIe 3.0 : https://unixsurplus.com/solarflare-SFN7501-adapter/

70$ Silicom Dual 10GB SFP+ PCIe Ethernet ADTR Intel X520 Chipset PE210G2SPI9AE-XR-NU : https://unixsurplus.com/silicom-pe210g2spi9ae-xr-nu-adapter/

79$ Supermicro AOC-STGN-i2S REV 1.01 Dual Port 10G SFP+ Intel 82599 Network Adapter Rev 1.01 : https://unixsurplus.com/supermicro-aoc-stgn-i2s-adapter/

If only a single 10GBASE-T SFP+ transceiver didn't cost as much as a pair of MMF SFPs and hundreds of feet of OM3.

Not to mention that depends on the cooling of your switch and the quality of the transceiver, it wont necessarily do the full 100m over copper.

 

Its just generally better to use fibre if you can as it uses far less power, the transceivers will run a lot cooler and it takes up a lot less space thus less intrusive should you need to mount it to a baseboard rather than in-wall.  I wish I could use more of it myself as replacing just one CAT6 cable with OM3 freed up so much space in the ducting.

Thanks, this was exactly what I was looking for, and thank you everybody else as well for helping out
