1GB Cable internet vs 2GB Fiberoptic internet

2 or 3 quick questions my current cable company(Comcast) I have their 1 GB internet and its "ok" but it has the typical up/down thats very skewed and you can tell if say my son is watching/streaming videos or downloading a big game/// it is a obvious slowdown/bottleneck on/to the entire internet.

They just have been since last year running fiberoptic cables( a few different companies) some underground and some through where the telephone wires went/telephone polls.. One just got up and running and they sent a guy around to let us know... I can either get 1 GB Fiberoptic for about $30 less than the Cable OR I can get 2GB Fiberoptic($85) for the same price as my cable 1GB is.

Now to the questions

  1. Should I get the 1GB and save $30-35 a month OR Get the 2GB Fiberoptic for the same price im paying now??

  2. will I notice a difference and if so what I know up and down are supposedly both 2GB so that will be different im assuming Fiber wont bog down like cable does during download events?

Offer

I’m a junior Computer Science major, and today at work, I had an interesting opportunity. A customer, who happened to be a company owner, offered me a position, and the district manager was there as well. Their company is small but growing, working with major tech firms and city projects. They offered me a role as a fiber optic splicer and asked me to send my resume along with my pay expectations.

When I asked about opportunities aligned with my Computer Science degree, they suggested focusing on understanding the data generated through splicing and applying skills to interpret and manage that data. While I’m open to splicing, I’d love to explore a path more related to data interpretation, automation, or systems optimization within fiber optics.

Do any of you have insights on roles in fiber optics that might align with these areas in computer science?

How does one "couple" together fiber? How easy is it to do so?

I want to run 10GbE as the backhaul through my attic, serving as the backhaul of the home network. I'm very concerned about damaging the cable, getting it into the wall up the attic and then getting it out through the wall from the attic. I would, instead of using one full 150' run of fiber, I would prefer 3 segments of fiber:

  1. ingress: a 25' of fiber where it gets it into the wall and up into the attic
  2. the "actual" backhaul through my attic: 100' of fiber
  3. egress: a 25' of fiber where it gets out of the wall out from the attic

This way, if I break/damage either of 1 or 3, I'm not throwing away a 150' run of fiber but at worst, replacing two 25' of fiber

If this makes sense, I need to "couple" these three pieces of fiber together:

i. Is this possible to do so? ii. How does this affect signal integrity? iii. How easy is it to do so?

Fiber splicer newbie questions

Hey all, I've been lurking here for a few weeks and see a lot of good stuff and experience.

I am a 20+ copper guy and just bought a Signal Fire AI-9 to start doing my own terminations instead of subbing them out. Very little volume, like maybe 24-48 strands per month at schools and business parks, maybe some direct bury outside stuff, but nothing big. 6-12 strand OS2 terminated to fiber patch panels in racks mostly.

So, first is OS2 the way to go for pretty much everything like this?

Next, what items do I need to actually do the terminations besides the splicer? LC connectors probably exclusively. I see cheap pigtails from fs.com and also find more expensive SOC connectors. For what I described, is there any reason to use expensive SOC ends? I am thinking pigtails just get neatly coiled up in the patch panel enclosure.

I've watched a few YouTube videos, but am left wondering about some details like shrink tube and misc expendables. Can you guys point me in the right direction to get all I need to start?

Thanks in advance!

Fibre optic books/ info request

Fairly new to the fibre side of the world, I have a history of working in roadworks and have recently progressed into the world of fibre.

Does anyone know of any good books/ info sources to help me wrap my head around the system?

Looking for professional advice as someone new to the trade

Ok, so I have been working in fiber installation for a few months for a guy who is a 1099 contractor. It's just him, me and one other guy most of the time. When I started I did a lot of splicing, which I enjoy and would like to specialize in. I finished an online class on Udemy which was super helpful, but isn’t a real accredited source or certification.  That’s the extent of my knowledge and experience. I know the basics, I can splice well and pretty quickly, and I have some experience testing, but not much (just link verification, no specific insertion loss testing or OTDR analysis).

This last month my boss said work would be slowing down and I should look for work on my own (He will likely be retiring soon anyway). I started an LLC and am wondering how to get my foot in the door to get work. I am confident I can do quality work but I feel kind of under-experienced and was wondering if I would be better off just getting employed by a larger company for a while and then splitting off once I’m confident or have more contacts. 

My boss gave me a couple contacts to call, but I’m wary of calling because I don’t feel particularly qualified and can’t really sell myself beyond “I’ve done this for a few months.” 

TLDR; I only have a few months of on job experience and my current gig isn’t going to last long. Am I better off getting a job at another company or could I make it work on my own with what I know?

Fitel Ninja NJ001 any good?

Work for a large ISP, this is the new battery splicer I was given. I have been using a Fuji 31s, and I have no complaints. This seems like a direct downgrade in terms of build quality. Anyone have any experience on these guys?

Question about outdoor ONTs mounted in demarcation boxes.

How often are these still deployed with the fiber optic industry? I have a provider moving into town called C Spire fiber, they seem to use these and will install it outside, then run an ethernet cable inside the home. It is what I gathered from their home install video posted on their YouTube channel.

What happens if a customer cannot power this ONT outside and has no nearby power outlets? Would a power adapter be installed inside the home and routed to the demarcation box?

Man this stuff is tiny!

This fiber cable jacket is 3.5mm and has 12sm fibers inside. Been playing with soft peel for a few weeks! No need for fiber strippers.

Damage fibre line

Hello I’m renovating a 30+ year old condo that has a non load bearing wall that I want to demolish and the building management reports that there is fiberoptic line going unit to unit through this wall. The management is saying that there are two companies in the building who run their fibre through the wall to other units. My question is how do I do proceed with the demo, I’m the homeowner btw, should I hire someone to scan where exactly the wires are (this is proving difficult) or do I just do the demo and hope to be gentle and not touch the run. Also if u hit the cables how much will the companies charge me roughly?

What’s The Best Cable Tensioner Hoist.

Is it better to use a chain hoist or strap hoist for strand/messenger wire. Is 1/2 ton 15ft chain the best? Any brands recommended?

Core won't splice

Anyone have a thought on why this won't fully splice? Core won't fuse but the cladding will. I've been casually splicing for about 6 years and I've never seen this before. It's only on this specific batch of pigtails and this is the 8th one that's come out like this.
