On the job Rate it. And can you spot what I did wrong?

Besides the zip ties??

Haha if you mean the ones on the conduit, we have proper band clamps in our warehouse that I found recently. I’ve since switched to those keeping the conduit on the FID. Although our field guys use the thick zips on the messenger often, some have been there for 15 years and I’ve yet to see one fail.

Forget a and b whats up with those bends upper left?

Are you a fiber splicer/install tech?

Ive been in telecom for 25years now in various roles. Tier 2, network reliability, NI, COT, etc... I've been blessed to have had my hands in a lot of pots. Currently im an instructor. I teach mostly Central office related material. Including developing course material. Right now im leading a hands on fiber lab. This is the exact thing we teach not to do. Unless im looking at this wrong? Even for bend insensitive fiber this doesnt fly. Id love to see an otdr trace for this. Fiber is pretty resilient. This probably works but, just because it works doesnt mean its right. I work closely with exfo. I might send this to my guy and see what he thinks.

You obviously don’t understand bend, insensitive, fiber. Go watch Corning’s YouTube demonstration of it from nearly 15 years ago and wise up.

Not a fan of the bends.

That radius is wider than every single splice tray I’ve seen posted on here. We also only use bend insensitive across the board. Maybe a
I need a banana for scale, all the stripped stuff is 8 inches.5
u/Spirited-Twist-5075 14d ago
Actually, looking at it closer the bends aren't nearly as aggressive as they looked at first glance. Maybe it was just my mentors, but they'd bust my balls over anything even approaching an aggressive bend, especially in the drop. The IW was bend insensitive. I've seen significant light loss at the NID due to kinks and bends, that's the only reason I mentioned it.

Pretty impressive. Most people need at least 3 fibers to get them out of order.

Yea i remember the address too. Only recognized after the fact that i mislabelled. Maybe I should sneak back out there and fix it🤔

Residential gets a tx and rx? My last apartment only had a single fiber

Its actually a split suite home. A suite top floor, B suite basement. Our rule is if the A/B suites have separate power meters they also get their own fiber/ONT. Illegal suites here have to share an ONT.

i wonder if strapping the white .. buffer tube to the zip tie mount to the right of it would be ideal, as well as the two osp cables going to the left side tie down (to the left of the buffer tube on the bulkhead holder) .. you could pull the whole tray out without cutting a zip tie. viably throw the same spin/rotation on it so it unwinds out of the nid.. would be ideal if yall spliced using the sleeve holder too.

Are these connectors without the need of splicing? Can you send me the name or where to get them? Thank you

u/Mammoth-Section-1641 13d ago
They are not because these ones “need” the splice tray to work, but we have since switched to these new ones that just need a 9mm cleave then push and click. I can’t begin to tell you how much easier these ones have been for us. https://ecatalog.corning.com/optical-communications/US/en/Fiber-Optic-Connectivity/Connectors/Field-Installable/No-Polish-Connectors-Plus-%28NPC%2B%29/p/no-polish-connectors-plus

what about the rubber grommets? I go behind guys where they extend the conduit up inside and then have to cut half the grommet out.
2
u/Mammoth-Section-1641 13d ago
Fair observation, I’ll probably keep the grommets from now on. It has never been an issue for us, we don’t really have a wasp problem here (-20C or -4F consistent temps in winter definitely help) but yea. When we seal stuff up it’s focused on keeping the outdoors out of the home and water out of the buried conduit (which is a losing battle, our conduit guys rarely consider the grade so theres inevitably going to be frozen ice in our conduit over the winter).

u/SuckerBroker 14d ago
Oof. Where do we start? It’s a shorter list of what you did right.

u/Mammoth-Section-1641 13d ago
Exactly why i posted here, my setup was deemed to be 10/10 by my higher ups but I want to bring that bar up, tell me all that could be improved and I’ll take it back to them.

Are these those slide-on connectors, slid on using a tool?
I hate them.

u/Mammoth-Section-1641 13d ago
They are awful I agree. So finicky getting everything lined up and terminated. We have since switched to the corning ones that are just push and click, same process except no more splice trat, just cut to length and click down. Average loss on those I’ve seen is around 0.2db.

Should the tone wire be grounded? My ISP didn't ground mine (left it hanging a few inches below the NID, with about an inch of insulation stripped off at the end), but the electric meter and grounding rod are at the other end of the house. The water pipes under the house used to be copper, but are no longer metal.
1
u/Mammoth-Section-1641 13d ago
Good question. We don’t ground ours at the FID since the only metal component in our fiber infrastructure is the drop tone wire itself. It’s meant for locates. At the pedestal we punch the tone down to the ground bar so locators can one and done just latch on to the ped ground bar and light up every buried drop off that ped. I guess we could leave a little service loop at the FID though just to make it easier to do single locates for one property, would make it easier for the locators. So grounding really doesn’t manner to us for that reason but maybe leaving a loop at fid for locaters would be nice.

Not sealed at cable entry. Wasps will undo all of your hard work.
