When troubleshooting a fiber connection, the optical power meter detects "tone" from the customer/end users CPE. Doing measure at the node/coe, disconnecting the patch cable from the ODF and then connecting a short patch cable from the power meter to the port on the ODF.

The SFP at the customers end is BiDi TX/RX=1310/1490nm, 15dB.

While that CPE is transmitting, I would not expect the power meter to display "Tone".
What am I missing or what is it that I do not know? Because I can not understand how this is posible... :)

As the title says my office needs more of these handy tubes that won't bend, they keep the buffer tubs from kinking in tight spaces. I cannot find them anywhere though. Does someone have a name or recommendation for where I can find more?

Does anyone know of companies hiring drone pilots for power pole or cell tower drone inspections in Oregon or SW Washington? Thank you

Or would I need some attenuators

What's the one piece of advice you wish you had wen you started to learning this job / Or at the beginning of the year

I have an OLT, ONU, and splitter setup I want to use in my homelab. Its all hooked up, but obviously there is no link set up, due to lack of microclimate. Any other options?

So I'm used to splicing strictly SM fiber. Everything you could think of SM. I'm curious on the differences between splicing SM and MM. I've used fujikura 90s and as long as I changed the settings, would it be the same as SM? Just on the splicing side is it basically the same?

So im changing to optic internet but mostly why i need faster internet is pc so i wonder how it works is it the same way i connect normal internet? Like ethernet cable to the motherboard or i need some new stuff?

I have about 96 OM3 splices to do for an infrastructure upgrade, we have the fiber pulled, but during the project there were some issues with the cabling company and it was never terminated.

I've spliced before using an older Fujikura model and for the sake of time and money figuring I'll just do it myself.

Looking to buy something inexpensive, figuring it will allow some flexibility in the future to be able to repair or replace other fiber runs. If I do more than a couple of dozen splices a year after this initial project I'll be surprised.

I see things like the Qiirun and Signalfire on Amazon for core alignment splicers in the $1000 range, I also see some Fujikura 12S and Sumitomo Type 400S for about the same price.

I know I'll get a lot of differing opinions, but at the moment I'm leaning towards the Fuji or Sumi models just because I know the quality is going to be good, as will support and replacement parts / repair if something goes wrong. Is it crazy to buy a name brand cladding alignment splicer over a no name core alignment?

Hello,

Long time reader first time caller? lol Seriously though, had my outside fiber break last night. We live in the middle of no where and one of the last houses in our small community's county to have access to fiber optic internet. It is literally the only internet provider for our house. They have ran the cable three different ways. The first time was a disaster because the guy didn't even secure it properly to the house so my dog got a hold of it. The 2nd time it broke, we assumed it was the dog but now not so sure. The 2nd install the guy ran it under the siding of our house, which is why I doubt it was the dog the 2nd time. This time it broke, it broke right under the window by my computer desk and I didn't see or hear her at the the cable instead she was at the door wanting in.

It did get pretty cold last night, around 19 degrees or so. I am not sure what happened. I use to have a CCNA from Cisco but didn't keep it up as I am not disabled. Back when I got it fiber was pretty new and I never had a chance to work with it, which is why I read on this forum from time to time just out of curiosity. The cable we have is ran all the way around our house instead of through our house. We gave the ISP the option of running it through our house instead but they have opted to go around the house instead each time. The cable comes up out of the ground into the external box one side of the house and all of our devices are on the opposite side of the house.. The 3rd installer (last guy who did it) I even told him he could just run the cable into our bedroom which shares the wall with their box, down through the floor across the basement ceiling and back up into our living room where our device are but he said the ISP rather for him to run it all outside.

The reason for my post, based on the picture anyone have any idea what happened. the cable looks almost pinched and snapped. Could a rodent or some other random outside animal do this? It doesn't look bitten by my dog or pulled down. The time we know for sure the dog broke it her paw just got caught on it and she just yanked it off the side of the house. Could the cold cause it to snap? We got snow/ice with our cold weather. It was not as cold as it will be later on this winter, but below freezing. I also have a 2nd question, when running fiber outside all the way around a medium sized house is it normal to not run any kind of protective conduit over the cable? The ISP first told us we couldn't do it then told us we could so we bought some for what was in our dog's reach this last install. I could replace the cable my self but it would void our contract with my ISP. Which has put us in a bad situation because it is 85-100 dollars each time they come out to fix stuff. Sort of feel like we are being screwed over.

Thanks :)

Hello,

I’m looking for something that’ll measure optical power of different wavelengths in a CWDM system. I’m looking for it to do it constantly too and log or to be polled by something like SNMP.

I’ve seen plenty of handhelds but I’m looking for a more permanent install so rack-mount or card-frame at least.

Has anyone come across this / could point me in the right direction please? The closest I’ve come is a FS OPD in the FMT form factor but this will just give me light level across the whole spectrum.

Thanks!

Hello Im currently working in remote British Columbia 🇨🇦 Have a few networks to splice with this 144F Corning ADSS cable. It is attached with oversized drop hangers at poles and no strand or lashing (obviously). Has anyone worked with this before? Im not sure what kind of weight restriction this has as I have locations to splice where i would need to mid span with my ladder to access cables.

Im in the dmv area specifically around the chantilly/manassas/centreville area are their any companies that people know that will help me get a entry level job as a fiber optic technician specifically as a fiber optic splicer, if so what do I have to do?

Hi Everyone!

We just recently got fiber to our house, and we are using this wifi router:

Ubiquiti Fiber Wifi UBNTF90BD3D0

We get 100mbs download speed when directly plugged in but since the house is 3 stories, the range doesnt reach that far when on wifi.

My question is, are there other routers we can use that will provide better range for our wifi?

Thank you!

Hey gang, sparky here. I’m doing a commercial building (remodel). Owners are upgrading to fiber. Comcast is putting in the vault out front it’s my job to give them a chase from their vault into the server room then back outside to feed a separate building.

I’m going to trench and use 1” pvc from the vault underground to a 90 degree sweep up the wall and into a j-box to transition into the building through the back of box. Running 1” inter-duct out of back of box to a cable tray - to server room - back out of server room to another box doing the same thing on a different wall to feed the other building.

My question is what size box do I need for my riser to transition in and out of the building? Guy from Comcast said no more than 30 degrees of bend. How is this possible without using a ridiculous 16” deep box or whatever?

Thanks to anyone who has some input.

Hey guys, possibly dumb questions. What are these tubes called so I can order more? I refer to them as just buffer tubes but when I search online to order more they don’t show up in the results.

Hello, This device is from job lot. the device turns on, which is visible in the pictures. also the buttons works. It reports a message that the battery is low, further testing was not done, because I don't know how to use it. Price: US $150.00. I accept Paypal, and shipping is from Croatia - EU.

When deciding on Fiber over CAT6, here are the assumptions I made for residential home networking. Please let me know if I'm wrong and why:

1. My understanding is that the very same fiber we are lying down (details: https://www.reddit.com/r/FiberOptics/comments/1h227ba/how_bad_are_these_equipment_and_this_idea_of/) will see us from 10 Gbps through 100Gbps, essentially implying that we would never have to redo this ever in our lifetime?
2. This is a trial run to some external runs to a remote garage that's currently using Ubiquiti PtP radios (thus limiting the bandwidth to 300Mbps). Lightning strikes in the past had burned parts of that same garage and fried all power tools and equipment in it. Fiber should completely isolate another lightning strike also killing equipment in the main house and potentially causing a fire
3. When I was looking into Fiber to RJ45/CAT6 trancievers, to see whether I could use really cheap fiber only managed switches, I noticed these trancievers are extremely power hungry and run hot so I'm assuming (perhaps wrongly?) that purely fiber based equipment will be way more power efficient than CAT6 based equipment?

I'm an absolute fiber newb here and doing this for my coworker's house. See more context at the end.

The walls in the house have thick fiber padding insulation making feeding cable really difficult requiring a lot of force. We are thinking we will use these parts and technique:

1. Couplers: https://www.amazon.com/dp/B099K59F1Q/
2. Either https://www.amazon.com/dp/B0BBZZV9ZC/ or https://www.amazon.com/dp/B0CFMWY91C/ for the internal attic run from one end of the home to another
3. Cheaper, disposable (non Armored) fiber (something like https://www.amazon.com/dp/B08B3Q4ZZ6) to connect #2 from wall to attic and attic to wall. These might turn out to be unnecessary, in which case we will return these for a refund
4. Have a PC with a 10GbE PCIe card on one side and this on the other side of the cable run: https://www.amazon.com/dp/B0C5D4MYRF/
5. We believe we will also need an "adapter" that connects the fiber cable into the 10GbE ports? So 2x of these? : https://www.amazon.com/10Gtek-SFP-10G-SR-Transceiver-10GBASE-SR-300-meter/dp/B09XQT83BR

The plan is to:

i. Feed pull rope through enclosure in walls pulling using metal pull cable from attic

ii. Tape the head of #3 to pull rope and pull into attic

iii. Connect #2 laid out in the attic using #1

iv. Repeat the same on the other side

If 2 can run from wall to wall without damage and without affecting signal intergity, we will do without #3 and return those for a refund. Unsure how much loss of signal at step (iii) but since it's an approved Keystone Coupler, I don't imagine it would affect anything over a 150' run?

We are taking this approach because the fiber will face the most likelyhood of damage when feeding it through the wall and into the attic - having cheap throwaways to handle this risk seems to make the whole run resilient to damage and if it turns out things arent as bad as we thought, we could just pull the main armored cable (#1) down from the attic into the walls

More context:

The weather's cool now to enter the attic almost anytime of the day so he wants to get pending work in the attic done. I suggested he puts in some single mode fiber to make his home network future proof and we are both excited to learn how to go about this

I'm an absolute fiber newb here and helping a coworker setup our first fiber network and good pricing would be awesome but we should also be able to return products that we thought would work but doesn't (besides fault in the equipment it could also be due to our ignorance).

Hoping to purchase 1x 150', 2x 15-25' of ready made single mode fiber, couplers or keystone jacks and anything else I'm probably missing

Amazon has been great with returns even if we open the packaging as long as we don't damage parts - they don't charge us any fees like restocking/return fees (returns are free) - is fs.com the same

If there's something as good as Amazon with the quality of fs.com, please let me know - I used to purchase CAT6 from Monoprice but their prices and quality have become incompetitive

What are yall using to drop hitch on bucket truck to get it low enough to pull splice trailer?

Is there a certain brand or model of a red light that you would recommend?
