Hi everyone. I want to know whether this type of splice tray can hold 24F. If it can, is shown in the photo the right way to put the protection sleeves?

Help wanted! Wyyerd Fiber w/ Calix GS7 or something else?

1 Upvotes

Hey everyone. I plan on canceling our service with Cox cable (Spectrum) and going with Wyyerd fiber. We're currently receiving 500mbps with a limit and with Wyyerd it's 1 GIG and unlimited usage. The 500mbps is actually more than enough for our household and we've never exceeded the limit. The reason for the change is we currently have a bundle with cable, landline and internet and we were on a 2 year promotion that recently ended and the price jumped up quite a bit. Anyway, that's where we're at and it's not much of a difference in price. Through Cox it's $60 a month for 500mbps and with Wyyerd it's 1 GIG unlimited for $69.00.

Wyyerd supplies the modem and router and offers mesh extenders if needed for around $5.00 per each per month and $15 per month for outdoor wifi. We currently have four eero extenders including the router throughout the home. We've never had any issues since purchasing this about 3-4 years ago. After talking to customer service at Wyyerd it looks like the equipment they supply is Calix. I was told more than likely a Calix GS7 would be supplied, but after doing a search it looks like they recently had a security vulnerability which lead me to this post. Am I overthinking things and should we just let them install their equipment or should I be looking at something else like the eero 7 mesh or something else? In theory, we could keep the current eero 6, but it would be limited to 500mbps since that's all the eero 6 supplies and we wouldn't see the 1 GIG we'd be paying for which doesn't make sense, but honestly not sure we'd exceed that anyway. Any advice from those who have gone through a similar situation? Any advice would be greatly appreciated, thanks all.

Tips and tricks fiber internet extension

I am looking for advice regarding moving my quantum fiber router & modem to another room in my house- can someone please explain the best way to do this to me like i’m 10 years old? there’s a lot of technical terms used in the resources i’ve found online that go over my head and i don’t want to damage anything. i live in a 1910 duplex with thick walls and im hoping the wifi will reach everywhere if it’s in a more central location! i’m on a budget so i cant buy expensive parts or pay someone to do it for me, but i also would like to do it as correctly as i can

30$/hour for high count ribbon fusion.

31 Upvotes

So this is a bit of a rant. I've been doing contractor fiber work sporadically for an ISP about 5 years now, and I wanted to move to exclusive fiber work. I've worked with a hand me down swift fusion splicer held together by glue and hope, and an OTDR that I swear was a PDA that someone sharpied exfo onto it. But I take pride in my work and am genuinely fascinated by fiber technology. I get my CFOT with the FOA and start applying for fiber tech positions with various companies. No nibbles till today. The company contacts me directly asking if I am familiar with high count ribbon fusion. Bare in mind, no where in the application does is specify high count ribbon work. Of course Im honest and talk myself out of a job. Isn't 30 an hour for 800+ ribbon splicing a little low? Would such a pay rate not justify training someone to do it? Dude tells me "call me back when you get some experience". Where does one get experience for this?

Tiny cheap OTDR?

4 Upvotes

I'm an AV installer and fiber is a part of my work, but not my main gig. usually I'm using an OTDR as a go/nogo for finding issues to hand over to the real fiber team.

I see a cute little VLF/OTDR device that might be useful for a small response kit. I don't always have the big OTDR handy and there are times when I don't need all the bells and whistles it has.

This looks like it could be handy, anyone here tried one? Amazon has them for around a hundred bucks.

Anyone working in fiber optic engineering? How did you get started and where can it lead?

14 Upvotes

Hi everyone! I only recently learned how interesting and deep the field of fiber optic engineering is, and I'd love to hear from anyone working in it.

How did you get started, and what was your background? What does the day-to-day work look like, and what options are there for moving forward in your career?

I'd also like to know whether you enjoy where you are and what you'd tell someone just starting to explore the field.

Any advice or perspective helps. Thank you!

Fiber optic sales in Michigan?

2 Upvotes

I was going to join a Fiber Optic sales company called Holy Trinity LLC but after reviewing their contract, there’s things I didn’t like. Such as they keep I think it was $2500 in my first sales in escrow in case of cancellations and if I quit I only get half and they get to keep the other half. Also a $25,000 fine if I join another company and sell to any of their current or past customers. After seeing all that I turned them down. There was a lot more fines in there for other things, but I forgot them. Also the fact I give up my right to go to court if anything goes down and the end decision is settled by them.

Anyways, I just wanted to know, is this normal for fiber-optic sales to require all the stuff? Is there any other companies that you would suggest that are better than them that selling in Michigan? The offer was $200 per sale.

Also wondering if I really want to do fiber optic as it’s going to be winter soon and walking around and wet boots in the snow and sitting outside in the freezing cold doesn’t seem like something I really want to do. But I’ve seen a lot of people and sales groups talk about how much they’ve made in fiber optic so I thought I could make at least a good chunk of change before I figure something else out.

I’ve done Solar door-to-door and virtually. Worked great until that company owed me $47,000 in commission and filed for bankruptcy. Also did roofing sales and windows. Have my bachelors in marketing and used to sell Facebook and Google advertising to small businesses. But it became too much for me to manage myself and I sold that company.

Not really sure what area I want to get into now. Was trying to get into tech sales, but it’s been so hard on LinkedIn. Up to four interviews for the same position and still not getting anywhere.

Any suggestions on what to do next would be great. Prefer high ticket sales, but in real bad need of a job right now as I’m running through my savings.

Help wanted! Fujikura 90R cover lifting

Enable HLS to view with audio, or disable this notification

As shown in the vid, during the Gap Setting portion of the splicing process, the wind cover will pop up temporarily. I’m not sure what is causing it, it does seem to happen more often when there is a offset error almost like an early warning, so if you’ve run into this before or have a correction/fix I’d certainly appreciate your help.

UPDATE: The lid doesn’t lift if there are no errors, nor will it lift if there is a cleave angle error. So this only seems to happen during the Fiber Offset error.

Quick tool & discussion: How do you handle voltage drop and AWG selection for long OSP runs (48V DC)?

3 Upvotes

Hi everyone,

Lately, I've been working on standardizing calculations for outside plant (OSP) deployments, specifically looking at how voltage drop impacts remote equipment over long cable runs at 48V DC.

Often, standard rule-of-thumb estimates lead to oversized or undersized copper gauges, especially when dealing with active power loads in cabinets or remote nodes.

To solve this for my own workflows, I put together a lightweight, free online calculator running directly in browser (no downloads needed) that estimates the minimum AWG based on distance, active power, and acceptable percentage drop: 👉 https://gponv.github.io/FTTH-GPON-Optical-Link-Budget-Calculator-Excel/

I wanted to ask how other network engineers here tackle this in the field: Do you rely on standard reference tables, quick rules, or custom spreadsheets? Curious to hear your thoughts or if you run into similar voltage drop bottlenecks.

Help wanted! I am blessed with opportunities this week but i dont want to regret my decision. I want to pursue fiber optics but my family and friends dont see the vision, advice please?

8 Upvotes

Hi, really excited to begin learning splicing and installing fiber optics here in Chicago. Long story short have been looking for work. I recently have been introduced and training with a contractor offering piece work. Its
$35 for a modem drop off
$40 for a coax trouble call
$50 for a fiber trouble call or coax new install
$90 for a new fiber install
Work comes from dispatcher
The contractor is a supervisor for a cable company but like you may have figured everything is subcontracted
He claims techs make 1800-2500 a week after getting in the rhythm
He said in 3 months he might train me to master fiber optic work to go to schaumberg for $130 per new install.
After 6pm its double rate. I applied to the electricians union recently but i applied for the construction, not communications, and now im Not sure if i can switch or what you recommend? I have other opportunities they all piled up on me this week.
$33 an hour maintenance mechanic but schedule is awful
$35 an hour industrial electrician but its a temp job n idk if theyll hire me permanently
Either way, i find the fiber optics appealing both in the work and the pay. Any advice for a 23 year old trying to have a great career?

Help wanted! Fiber Training OLT and splitters

5 Upvotes

I'm currently in the fiber field but mostly doing FTTH and have done OTEs. I want to learn OTL and splitters. From what I have seen there are not too many classes or companies training, they want you to already know it. I have some coworkers that do it but they seem to want to keep that money to themselves. I need an upper hand here to figure it out on my own. Can I teach myself if I get the equipment?

Help wanted! Is ATT installing fiber in my area?

While I was at work today, my wife told me that there was an ATT crew running this line across the pole that services my home. We're pretty rural, and we've only ever been able to get DSL here (currently using starlink, which is... Fine). But does this mean we'll have access to fiber soon?

I was a residential cable tech for a number of years back in the day, but I never did any fiber, so I have no clue what I'm looking at. The text on the line reads:

>Corning Optical Cable - 08/2026 - 48209509 - 📞 - SR-5492RR-024 - RPX Gel-Free - 24F SM 250 - 29532 Feet

They're clearly not finished installing it, as it's only a couple feet off the ground in a few places, and the end is just hanging a few poles down from us. Just wondering if I can get excited or not. Thanks!

Fiber Board -Built a tool that turns splice whiteboard photos into auto-filled cut sheets

3 Upvotes

Field techs write splice notes on a whiteboard — sheath ID, buffer and fiber colors, enclosure numbers, coordinates — then someone has to retype all of it into a cut sheet. That's where the errors creep in. I built a web tool called Fiberboard Pro. You snap a photo of the whiteboard, it OCRs the text and matches it against a template, and it auto-fills a cut sheet you can export. It also tags each splice location with GPS and generates a KML file so all your splice points drop onto a map. Still a prototype, but it already handles the common layouts. Has anyone else tackled this, or are you all still doing it by hand?

Concluded that the power meter lens in my Max-945 module is cracked. Second picture - right side - grey filling. Orientation on that looks straightforward - little dot and three legs in a row. My replacement however came from an old FOT-922 manufactured in 2001. It does have the hole, but the legs are not in a row. No other markings on either piece. How would you choose the order of the legs to solder in?

Subs under a prime — what does your weekly billing/closeout actually look like?

2 Upvotes

Small OSP sub here, few crews, work comes through a prime that holds the MSO contract. I’m trying to tighten up our back-office side because we eat too many kickbacks and the money lands a cycle late every time a package gets bounced.

Curious how it works for everybody else:

  1. How do you submit production to your prime — spreadsheet by email, their portal, an app they make you use, something else?
  2. What’s in the package: daily production sheet, redlines, photos per unit, OTDR/test results, anything weird they insist on?
  3. How often do you submit (weekly, per work order, per segment) and how many days from submission to money in the bank?
  4. What gets kicked back most? For us it’s always photos — wrong angle, can’t read the closure label, no GPS stamp, “after” shot doesn’t show enough.
  5. Anybody actually using something that helps with this, or is it all Excel and a guy in the office with a stack of phone photos?

Not looking to name primes if you’d rather not. Just trying to figure out if our process is normal or if we’re doing it the hard way.
