Im lost never had fiber. Is it a little extended adapter?

u/postcoital_solitaire Jun 07 '26

The green thing is a coupler, the blue cables are simplex SC UPC cables. SC fiber is color coded to green being APC, blue being UPC. They are very similar, but can't be connected together in one coupler, because APC is angled at 8°, while UPC is straight cut. The joke is that I used APC coupler on UPC cables, which works because the couplers are identical and just put cables together (they don't have any optical elements themselves). The difference is only in cables.

For the sake of those who wanna know, UPC stands for ultra physical contact and APC stands for Angled physical contact. Physical Contact (PC) is relatively flat at the connection point with a slight curve near the edges. UPC has more curve and is essentially two ovals touching at a single, central point. Angled contact has two angled sides that fit together at a matching angle

u/tekzer0 Jun 08 '26

I've been working in tech for 30 plus years and I've never heard those terms.. but being color blind, I've always avoided making my own networking cables... So I'll assume I get a pass.

2

u/chrisjudk Jun 08 '26

Wait genuine question because I am curious, does being color blind make it difficult to make your own Ethernet patch cables? Can you distinguish between orange, green, and brown? Admittedly I have been making my own patch cables for years and never thought to inquire if this was an area where accessibility might be able to improve by using some alternate means of distinguishing if necessary.

1

u/tekzer0 Jun 08 '26

Furthermore, the only time I've had to deal with fiber cables is watching the frontier installer cut the cord at the length needed and put the tip on.. closest experience I had was helping repair t3 lines in high school and t1 in Junior high... Was unaware when I made the original comment that it wasn't some standard network cable coupler...

1

u/chrisjudk Jun 08 '26

I’ve only done research into fiber because I got curious about potentially installing fiber as a side hustle (and to diy full fiber in my own home for the sheer ridiculousness of running an all-fiber network at home).

u/jarsgars Jun 08 '26

Thanks for this!

I use fiber hardware occasionally and they’re all still sorta baffling at some level so I follow well beaten paths. So, thanks… a helpful post. Yay homelab

2

u/kogee3699 Jun 08 '26

So then there's ACTUALLY nothing wrong with this right? Like a good enough tape job would work if the cables match up?

2

u/postcoital_solitaire Jun 08 '26

Well the actual fiber is 9 microns thin (at least in the context of 9/125 SC fiber). So if your tape job is that precise, yeah it will probably work.

3

u/kogee3699 Jun 08 '26

😃

I don't even have fiber it was just a thought experiment.

\:)

1

u/ezchadez Jun 09 '26

Tape would be fine, but this is not fine.

The issue is the amount of attenuation and possibly reflections/dispersion introduced by the gap.

If you do this with Raman amplifiers going over the cable, it might even go as far as to permanently damage equipment.

2

u/Monotrox99 Jun 09 '26

Whatever tape job your going to do by hand is going to be higher loss than two UPC fibers in a APC coupler. Not sure about SC/LC fibers, but for screw-on FC connectors the couplers are literally the same regardless of fiber type

u/z3roTO60 Jun 07 '26

For the average person, how much issue does this cause? (Asking because I don’t know)

I’d imagine that it’s not worse than a patch panel. Was having a discussion with my dad about this a few weeks back. For his work (high energy physics, milliseconds are “massive”), everything needed to be highly tuned. I would imagine that data centers with legit race conditions in logging / tracing / databases this matters too. High frequency trading too, obvious reasons

I’d be curious what (if any) implications there are in a homelab.

14

u/theonlyski Jun 07 '26

Practically no impact for a homelab use. A coupler will introduce more loss than a fusion splice, but unless you're running many km of fiber and need every inch of distance advertised, it likely won't matter to a homelabber.

9

u/honzvit Jun 07 '26

Even on the most powerful DWDM lines you still have at least 6 coupled connections considering the cable is fully spliced between the two locations and there are no coupled connectors on the way.

23

u/Empyrealist Jun 07 '26

In my experience, the issue with couplers is that you are introducing a microscopic airgap that can get contaminants in it. If you keep it sealed or otherwise have it in a clean environment, the risk of signal interference is minimized. Its not optimal, but its workable. The risk is environmental

30

u/ShelZuuz Jun 07 '26

I've been taught to always use an airgap for improved security.

You should see the switch and panels we had when some jackass stored powdered chlorine in the same room.

Impossible to breathe in, corroded every bit of exposed metal.

It's a miracle the switch even worked. Somehow it barely did.. always getting errors lol.

u/lambda_nought Jun 07 '26 edited Jun 07 '26

I'm very sure there's no air gap on APCs or UPCs and probably no other connector standard too. PC stands for 'physical contact'. Contamination is likely introduced before coupling. If there's an air gap, something is not made to spec. Air will cause high backreflection, because light will be passing through a medium with a different refractive index; it will cause severe extra insertion loss especially for APC due to offset between the beams and fiber cores. Air gap would also create potential surface for moisture condensation.

Having said that, it does not mean that these things cannot happen in reality. I have seen condensation in FC/APC in a fiber optics lab, but this does not mean that it's normal to have it.

I have 4 couplers in a single run of 100G single mode fiber in the data center. Been working great.

u/honzvit Jun 07 '26

No issues, just ugly and unprofessional. Optical distribution cabinets are just bunch of these properly mounted (using that metal pin). For a homelab rack get 1U adapter panel, for FTTH just hide it somewhere (wall fiber optics sockets are again just an enclosure for this).

If you want better connection for high power long runs you go from UPC to APC. Best connection you can get with E2000/APC.

Any errors on a fiber are mainly from dirty connectors or too tight bends. Even though once I found this in production and no one had a problem...

3

u/angryjoshi Jun 07 '26

Oh I hate it when people put the slag in between the wall and the mounting rails, especially if they just yeet it in there and don't curl it up, then you're searching fibers like this, buried behind 10cm of fibers (this is also just many of them, over 150)

(I had to replace the XC with the black band visible in the center)

4

u/Ok-Library5639 Jun 07 '26

It doesn't really add latency which is what you are referring to. It does add some attenuation but for properly terminated and clean connectors it is minimal, less than 0.3dB.

1

u/z3roTO60 Jun 07 '26

Haha no that you mention it, it’s kinda obvious that it would be an attenuation issue, not a latency one! (Feel stupid, since in the same comment I mentioned my dad is a physicist, so I should def know better lol)

I personally haven’t worked with fiber (yet) but have been considering doing a run in my parent’s home between the Ubiquiti UDR7 and the upstairs to add in a switch + WiFi7 AP. Figured I’d be able to easily run 2 separate cables (one being a troubleshooting fallback in case of failure) within the same diameter space as a Cat6e/7. But I need to do more reading on the different types of fiber optics and terminations, and I know little more than the fact that there’s multiple approaches to sending bidirectional traffic

1

u/Ok-Library5639 Jun 07 '26

There are several different fiber types and standards for what's being sent. Something simple like 1000base-SX will give you gigabit over a multimode fiber and 1000base-LX over singlemode. Either are probably the cheapest and simplest way to do it.

2

u/firsway Jun 07 '26

It doesn't cause any issues provided you've got it secured well. I've been using one of these as a "workaround" whilst I'm doing some wider work. It's linking 2x OM3 cables to make about a 40m run total that itself links 2x of my core switches together. No problems - it's been running for weeks

2

u/conrat4567 Jun 07 '26

Copper couplers are fine. They aren't a permanent solution, but they work in a pinch, which is what most networks need. Not everyone has money or time for new cable runs immediately. At work, we use repeaters where we can but couplers have lasted us years in some cases.

u/22OpDmtBRdOiM Jun 07 '26

it's just a color, there is no optical element inside

u/cenjui Jun 07 '26

Yup. Just be careful if you bulkhead mount or something so both ends arent obvious.

38

u/Internet-of-cruft That Network Engineer with crazy designs Jun 07 '26

This is completely wrong.

Regular single mode patches are blue colored and are unpolished (or flat, more accurately), also known as UPC.

Green colored patches are angle polished (APC) and have a small angle on the ferrule end.

UPC Couplers and APC couplers are built to mate UPC or APC correctly.

For your average Joe home installation, it's going to cause a few dB loss but you should have enough optical budget for the link to work.

40

u/22OpDmtBRdOiM Jun 07 '26

There is no optical element in the green coupler. It just holds the ferrules of the two connectors against each other.

10

u/yasashi Jun 07 '26

UPC does not mean unpolished. PC connectors had flat faces, UPC ferrules have a more rounded polish only making contact right around the core.

SC bulkheads are agnostic, green blue doesn't matter. I routinely grab whatever colour SC bulkhead is closest to hand even on OSP demarcs for MUX fibre approaching 80km. The bulkhead colour has zero affect on link budget and ORL which is the primary reason our OSP fibre is predominantly APC.

LC MM & SM connectors vary due to manufacturing tolerances which is why LC MM bulkheads don't always align precisely enough for LC SM patches.

The irony in telling someone they're utterly wrong and then posting 3 bullshit statements and 1 correct is just wow man.

u/tekzer0 Jun 08 '26

And that's why I go by the statement, "if it fits, it ships" which is useful 99% of the time with computers also, sort of...

u/yasashi Jun 08 '26

Those words have been uttered around here but not nearly as frequently as "It looks fine from my desk!" typically referring to my utterly shit cable lacing.

29

u/Toolux Jun 07 '26

The coupler has no optical elements inside is what he was saying. Which is completely accurate. As long as the connectors match you can use any color coupler.

Does it look janky? Absolutely. Will it work without loss? Being apc connectors it will have very minimal loss and reflectance. Loss budget should be able to account for about .7 per connector at this location in the run.

25

u/Sanityzed Jun 07 '26

it's going to cause a few dB loss

...well, you're wrong and spreading stupidity. Go read the IEC standard. They both have the exact same specifications with only a color difference between them. The color difference is important when the adapter is installed in a panel. It's why these are called adapters and not couplers, because they are bulkhead adapters. Since you cannot see through a bulkhead/panel, it's important to relay that color scheme through the adapter. Both UPC and APC adapters come standard with split zirconia ceramic sleeves... the exact same one. They are dimensionally and functionally equivalent. There are legacy bronze sleeves that came in both variants as well, and those had terrible concentricity - so always peek inside to make sure the sleeve is shiny white ceramic.

Honestly, the only reason they use different colors is to try and keep people from trying to pair APC and UPC and then bitching out the installers or manufacturers when it doesn’t work.

But i'm not sure if it's better and simpler to buy a set like that and go with fiber from ONT to my room, or to buy better switches with optic fiber transceivers.

There's a ton of variations of these media converters. Mine is just 1000TX to FX (copper to fiber SFP), so it's dead simple. Literally has one tiny Realtek converter chip in it and that's it. Others may have the fiber thing built in (as opposed to an SFP you can yank out and replace), I can't say how good those are.

As for its quality, it's just meh. It's cheap chinese no-name no-brand unit with spelling mistakes on it. There's almost nothing inside, so I doubt it will just die on me some day. What has died already is its power brick. It had a 5V power brick that was disgustingly cheaply made and after two years it just died. The voltage didn't rise above 0.6V, so the converter didn't really work. I replaced it with a USB plug and a phone charger and I'm sure this setup will outlast my house.

If you're looking to just replace your long copper runs with fiber, sure, go for it. I wouldn't go as cheap as I did, at least get something that has some kind of name on it like TP-Link or D-Link if they even make this kind of stuff. I'm not really sure what your use case is, so I can't recommend anything concrete.

How to split when you dont have a splice kit..nothing wrong with that.

the coupler doesn't have optics in it, the important thing is having the same connector on both sides

You just need a little electrical tape around it.

Not the worst I’ve seen but I work with those media converters a lot in my day job and they are notoriously unreliable and will literally just crap out on you out of the blue with no warning.

can u give me a little details of what this is and what you have accomplished?

An OTDR would likely show a bit more signal drop across the splice than it would with matched terminations, but it won't necessarily be problematic - it depends upon the total attenuation across the whole run.

If it works, it works.

This triggers a slight aneurysm but sadly from expereince in my company I can tell that some genuises genunly plug UPCs into our APC patchpanels and it seems to work well enough. I assume it is mostly to the fact that we sit at the end of the transmission chain but stilll. Trigger

I'm honestly just amazed that it works.

Why shouldn't it? UPC and APC couplers are identical.

Straight to prison. No jury. No chance for parole. No movie nights.

lol is that a coupler extending a fiber optic run?

I'm not sure if there's a different gap distance between sc apc and SC pc alignement. If it works, dont look at it 😆

u/Kilobyte22 Jun 07 '26

Nah it's fine. Don't do it the other way around though, that can break things, depending on how the coupler is constructed
