Any experience with rogue Aliexpress OTDRs?

Any experience with rogue Aliexpress OTDRs?

Hey, looking at buying this from Aliexpress as it seemed like a good deal and a nice form factor.

Does anyone have any experience with buying odd little devices like this from aliexpress? I've seen a few posts over the past few years, but not many links to what was actually bought. Thanks!

Thoughts on Why?

This is an outside shot on a house like two blocks south of cheese steak double mecca in south philly. I dont believe it is a business.

Any idea as to why they did it this way. Obviously idiots is an answer but do we have any other reasons?

Keep up the good work.

Built a fiber splicing app because I got tired of splice cans never matching the prints

After years of hearing:
“Does anybody know what fiber this is?”
…I finally started building my own solution.

Built an app called QuikSplice for fiber/OSP crews.

Main goal:
Make field documentation way faster and less painful.

Current features:
• Fiber color lookup
• Ribbon lookup
• Splice notes
• GPS timestamp photos
• Input/output cable tracking
• PDF report export
• Offline workflow

The idea honestly came from opening old splice cans that look like archaeological sites from the 80s 😂

Still early beta but it’s already being tested in the field on real jobs.

Looking for honest feedback from:
- splicers
- OSP techs
- utility crews
- anyone dealing with fiber documentation chaos

What feature would actually make your day easier in the field?

Anyone else ever lose all their paint after rain while the 811 ticket is still active?

We had locators out last Thursday and everything was marked pretty clearly. Then we got hit with about three days of heavy rain over the weekend. Went back to the site Monday morning and all the paint is basically gone. No faint marks, nothing usable. The 811 ticket is still active and doesn’t expire until Wednesday. Now I’m stuck deciding whether I should call for a remark or rely on my notes and photos from last week. Part of me feels like I already know where everything is, but I also don’t love the idea of guessing on an active ticket.

TMobile Fiber installer cut a hole in my roof

Installer came by today. He cut a hole in my roof to run the fiber through. I can see daylight. The installer drilled through a shingle. I've never seen something so half ass.

What Are You Using for Fiber Infrastructure Mapping?

Hello,

I wanted to ask what tools or platforms you’re using to build and manage your fiber network maps, including poles, drop cables, customer locations, and related infrastructure.

I’m still a relatively small provider, so solutions like VETRO FiberMap are difficult to justify financially at this stage. I also tried QGIS, but my experience hasn’t been great. I ran into several issues with elements resetting, objects that couldn’t be removed properly, and other bugs that made it hard to work with reliably.

What I’m really looking for is something that offers a clean and user-friendly experience similar to VETRO, but at a more reasonable cost for a smaller operation.

I’d appreciate any recommendations or insight into what others in the industry are using.

Found this in my back an hour after leaving acupuncture

All is well that ends well, but man did my back zing like heck and I wondered why! Until I found this. I did go back and get looked at and adjusted to make sure I was good. His assistant comes in sometimes and takes the needles out. She didn’t see this one tucked under my top.

fibercartel

Hey, did any of you guys follow fibercartel on Instagram a couple of years back? They used to post all kinds of fiber related videos from the field, but hadn't posted anything since 2024.

home network - splitters confusion

Hi, noob post, sorry. tl;dr - what media converters to attach to a 1:4 splitter?

I want to connect 4 rooms with a thin fiber (like in [this post](https://www.reddit.com/r/homelab/comments/1sz9li4/invisible\_bend\_insensitive\_bidi\_fiber\_is\_amazing/)) and found SC/APC-SC/APC, SM fiber. This would pair with [MC212CS converter](https://support.omadanetworks.com/en/product/mc212cs-2/) and PLC 1:4 SC/APC splitter.

I understand that for single mode patchcord I need two transceivers with opposite Tx/Rx frequencies, right?. But how does it work with a splitter? Do i get 1 x `1310 nm TX / 1550 nm RX` and 3 x `1550 nm TX/1310 nm RX`?

Or is this a totally wrong approach and maybe each room should have a dedicated connection to the router?

Thanks for the help!

Upgrading old Equipment

i currently have a old fujukura 17 s and a older Corning OTDR.

i currently do not do an ribbon splicing but may in the future.

any thoughts on some splicers and a otdr. my budget is around 10 k for both.

i have used the ct 50 cleaver and do not feel it is very good compared to the previous models, i have a old ct 20 that has worked for me for years, but i may have to upgrade my cleaver as well.

fiber holders are a nice to have but ive been placing my fibers to burn for years.

i am looking for a core alignment machine rather than cladding alignment.

comments and suggestions appreciated.

CDL Driver Meets Fiber Optics

30 y/o M USA KY

So, as the title says I’m a recently graduated CDL Driver. Right before I went into CDL school I got scooped up by a Fiber contractor, as just a hand while I waited to start CDL school. Apparently they’re very interested in having someone with a CDL.

Now, I’ve learned a lot about running drops during my time with them. Both commercial and residential, Aerials, Burials, easements, the works.

They are interested in keeping me on board. I’ve had other companies approach me to drive for them in a more typical CDL A position, and at first it seemed to be a no brainer that after school I would go and work for one of them and maybe continue running drops on the side.

Recently though, our supervisor has offered to also teach me to splice and pay for my certs as a tech and splicer.

Tl;dr has anyone ever heard of someone making a solid career with a CDL Class A, Fiber Tech, and Splicer?

Rate my work

Be honest, im a self taught splicer and working to clean up my splices. Any tips and tricks you might have would be great. I have a Belden branded Corning KF4 fusion splicer.

Ive been splicing for over 5 years now, but not for telecom or anything so usually i only get 2-5 projects a year requiring fiber optic. This is my most recent and i switched to splice on connectors from fusion whip sets.
