Lol … maybe somebody smarter will be able to make another video and explain better the SFP advantage
Agree about RSA720 - I want to sell mine
A simple test that demonstrates that SFP modules have different performances:
Ah, Alpha Audio, people who make Hans Buttheadszen look almost intelligent!
As with anything posted there the, the “test” demonstrates that they are a) crooks, and b) not very intelligent ones at that.
HI all!!
The optical fiber between Rs130 — Rd160 Dac is not working for me, what could be the problem?
internet — switch. OK. Finisar FTLX1475D3BTL + Corning SMF-28 Ultra + Finisar FTLX1475D3BTL
switch — RS130 OK. Finisar FTLX1475D3BTL + Corning SMF-28 Ultra + Finisar FTLX1475D3BTL
RS130 — Rd160. Not OK!!! Finisar FTLX1475D3BTL + Corning SMF-28 Ultra + Finisar FTLX1475D3BTL RS130 — Rd160 OK factory sfp cabel

I’m using the same SFP modules but with 2m OM1 LC to LC UPC Duplex Corning Fiber Optic Cable MultiMode 62.5/125 OFNR Rated, Orange between the 130 and 160 SFP modules. Works great.
- According to the datasheet FTLX1475D3BTL has Wavelength 1310 nm and is used with Fiber Type Singlemode. So it can’t work with Multimode fiber.
[https://mm.digikey.com/Volume0/opasdata/d220001/medias/docus/5731/FTLX1475D3BTL.pdf] - According to moderator rosehan, the SFP port for the RS130 network is 1Gb and does not support 10Gb modules, so the FTLX1475D3BTL should not work.
- For the RS130 to RD160 connection, several forum members use a DAC cable, Amphenol SF-SFPP2EPASS-002.
I am using FTLX1475D3BTL.
RS130 to Rd160 Corning sfm 28 ultra or Phoenix contact. No problems.
For enthernet:
Lhy Fmc to Rs130 ( FTLF1318P3BTL ------> FTLX1475D3BTL )
Lhy Fmc is not compatible with FTLX1475D3BTL.
Watch the arrows on the sfp modules and the patch cable numbers or letters.( polarity )
I tried a few different options between the RS130
And RD160 and decided on this: Genuine Cisco SFP-10G-AOC1M 10GBASE-AOC SFP+ Cable 1 Meter. Excellent results.i do like the copper Amphenol option too. I’ve been using I2S lately though, it’s still my favorite. I have fiber into the RS130.
I’ve tried all sorts of options and it doesn’t work with any version.
What is the recommendation then for a perfect optical connection. I don’t want to use copper cable.
Cisco SFP-10G-AOC1M best recommendation then, i think.
Very open and clear. I bought mine here, last two digits 1M = 1m / 3M = 3m etc.
Very good ebayer here

Christian!
I ordered the Cisco SFP cable from the ebay address you provided, which does not work between rs130-rd160. I checked the serial number and it is not in the cisco serial number verification database, so it is most likely a fake.
If you can’t connect with this, then how does it actually work? Because this is pretty bad!!! The whole Hifirose product is a big disappointment, that it can’t communicate with each other, only with some special cable!!
What solution is there???
Sorry to hear that, mine are all original by cisco check and i can‘t believe that seller does fake sales. You should ask them, they located in Vienna / Austria and very friendly.
Other members here bought them there, too with no issues.
Try to reach them by phone or mail, they will help you.
I won’t be dealing with the SFP connection any further, I’ve switched to the I2S connection which I think sounds better than the SFP, as I have to realize that the many improvements I’ve made to my system can now be shown from I2S as opposed to SFP. I’ve used I2S in my system before, but my sound system wasn’t at the level where the difference would show itself that much.
