1310nm SFP+ module for 6100?
-
Hey folks,
Anyone know of a 1310nm SFP+ module that will work with the 6100?
From here, https://docs.netgate.com/pfsense/en/latest/solutions/netgate-6100/io-ports.html it looks like everything is, as far as I can tell, 850nm.
My ISPs ONT is set up to use 1310nm only. -
Really? 850um is for multimode, 1310um for single mode usage.
Do they really use a single mode line into building?
But referring to the linked docs, a SFP Finisar FTLF1318P3BTL is using 1310um.
Same for Finisar FTLX1471D3BCL, its also a 1310um SFP.Regards

What module is the ONT using? Or is it fiber direct?
There are no particular restrictions in that regard. I would expect any Intel coded SFP+ module to work.

What module is the ONT using
I just heard back from them with more detail:
(Nokia 7210 SAS-Dxp) which does have an SFP port for an outbound fiber connection. We just need to know from you what type of fiber connection is required between the ONT and your router. We can do 1490/1270 BIDI, 1270/1490 BIDI, or 1310 Dual Fiber. We can do a custom MM fiber (850 dual fiber) but we will need to order a $15 part to do so.I originally told them to go with 1310 multi mode since thats what I'm most familiar with.
I guess I could do an 850 module since I have an intel 850 module already...

Don't be using single mode unless you have to, due to safety issues.
Could you not just use a copper port out.Never mind just looked at the spec sheet, the copper ports only go up to 1000

Doublecheck this: 1310um is usually single mode, 1300um is multimode (but this I did never see, only 850um).

$15 for them to use a standard MM module seems pretty cheap.

its certainly cheaper than anything I can get here in time too...

what's the safety issue with single mode? (didn't plan to use it, but curious)

Yes, I'd love to hear this also.
Probably gonna say something related to looking into the laser will damage your eyes but that applies to multimode also.
Can't wait to hear how single mode is more dangerous than multi.
Or any way it's dangerous at all. -
@jarhead single mode uses lasers, multi mode uses leds it that simple.

You can see MM light with your eye, and stop being "foolish"
You can't see SM light wo. electronic help (ie. phone cam).Some SM are long range - 70Km+ (Costly SFP's, high power laser diodes)
They are "Dangerous" for your eyesight, even short exposure. -

Most (all?) SFP modules, even high power versions, will not emit anything beyond the class 1 laser rating unless they are seeing incoming signal from the other end. So it should be extremely difficult to actually do any damage. But I'm not about to test that with my eyes.

Quick update...
It sounds like I'm the first 10G install my ISP (it is a new ISP) has done which is pretty fun. It also sounds like they are eager for this too and want to make sure it works.They said the Nokia ONT is pretty flexible in terms of optics and DACs it'll work with. That takes a lot of pressure off me for the install.
I have several DACs which, while not officially approved, work with the 6100.
It sounds like they have a big inventory of SFP+ modules too from FS we can try.
I'll let yall know how it goes.

Back in 2015 i had a lot of issues with "Cisco Clones" in my NEXUS routers.
They "wore out", and the light degraded.They were FINISAIR SM SFP's, and they were emitting light all the time.
You could test them by holding your iPhone Camera up to the SFP in 10 cm distance.If good the "screen exploded" in purple light , if bad there was just a weak light.
I don't know if they have made the newer SFP's more intelligent, as described above.
The issue i can see with the "wait for light from the other end" is ... Who will start to Emit ??

...
My knowledge from setting up numerous SAN FC fabrics:In FC cables light can only be seen if at remote end a component is active and emitts.
This can be a HBA or a switch. As long, as at remote end no active component exists, you cant see anything.
For a SFP it is sufficient to put the SFP into the switch/HBA.
As long as the switch port is not disabled you can see the light in SFP. So plugging in a SFP in a switch (or HBA if HBA is capable of using plug-in SFPs) you will see the light - if device is powered on .
Thats the basic test. Most switches I know provide further information using the management interface, i.e. wavelength, TX/RX power, uptime for switch and SFP, ...So if someone inserts the SFP into the Netgate appliance, you should see a light when using the cell phone cam. Even if it is a multimode SFP I would recommend not to look into the outlets with your eyes.
For the incoming line from ISP you can check also if a light is visible. If not, contact ISP.

@jarhead single mode uses lasers, multi mode uses leds it that simple.
Yeah, figured it would be something like that.
First of all, that's not even true anymore. Most of both types use lasers.
Second, why would it be "that simple"?? Why would a laser be a reason not to use single mode? Makes no sense at all.
I've been working with SM fiber for close to 30 years I would guess and I still have 20/15 vision. Do you know why? Because I don't look at the light with my eyes. Either single or multi. Just don't do it. -

Always use multimode if you can.

@nogbadthebad It's not a rule of thumb but good advice for cost only.
My point is, don't tell someone not to use single mode for safety. Tell them not to look at the light for safety.
There's nothing wrong with using single mode.By the way, to the OP, 1310 is not MM as stated earlier. 1300 is MM, 1310 is where it changes to SM.
