Level 3's Top Ten Reasons For Cut Fiber
Hungry Squirrels and Idiots With Guns
by Karl Bode Monday 08-Aug-2011 tags: Fiber · business · bandwidth · Oddities · consumers
Light Reading directs our attention to a new post over at the Level 3 Communications blog discussing the top ten causes for severed fiber strands. Not too surprisingly, people not researching before they dig was the biggest culprit. The blog has a few amusing statistics, such as the fact that a huge number of cuts are due to squirrels chewing through lines; in fact squirrels accounted for 28% of cut lines last year, and 17% this year. From the blog:

Click for full size
Of all the animals in the whole world, almost all of our animal damage comes from this furry little nut eater. Squirrel chews account for a whopping 17% of our damages so far this year! But let me add that it is down from 28% just last year and it continues to decrease since we added cable guards to our plant. Honestly, I don’t understand what the big attraction is or why they feel compelled to gnaw through cables. Our guys in the field have given this some thought and jokingly suspect the cable manufacturers of using peanut oil in the sheathing. If you have any new ideas on how we can combat these wayward rodents, I’d love to hear from you.

The company also notes that about 7% of annual outages are due to people using the fiber lines for target practice. There's also a few amusing anecdotes about sharks, crappy pilots and crazy people with shotguns.

Underground you wouldnt have to deal with people using it for target practice or the furry animals.

Call before you dig...

well at least L3 tells people about the cables...

unlike a few years ago when they where expanding the DC Metro and cut fiber that was not on any city planning or on the lists of any other carriers in that ROW. so when they started digging after the CBYD guys came they cut government fiber that was "unlisted".

I sure hope the black SUVs showed up around 12noon so the Forman could tell the black suits. "Sorry union mandated lunch break"

Re: Call before you dig...

It was. The road crew had no idea that anything (other than dirt and rocks) had been "disturbed" until the black SUVs showed up and dudes with bulges under their suit jackets jumped out and started pushing people around. The funny part was later when the Feds tried to bill the road contractor for the cost of the repair. The contractor pointed to the official county maps which showed there was no fiber (or anything else) at that location, ergo, there could not have possibly been anything to repair, ergo, take this bill for phantom work and shove it where the sun don't shine. I suppose the silliness would have been understandable if it had occurred inside the beltway, but this was about a mile outside the beltway.

Don't feel sorry for them -the lines should be underground!

Really stupid to blame animals and gun owners when they should blame companies for placing ugly wires everywhere on poles in the first place... Not just the little FIOS fiber lines, but dangerous (and ugly) POWER lines should be BANNED from poles! Poles were needed in the early 1900's but technology has advanced and ALL lines can be underground. They are just lazy and cheap! I'm shocked most small cities didn't make this a law... my power goes out all the time because of idiotic poles, not to mention FIRES starting from downed lines ...

OK, bury them all. However, during the winter with 5 feet of snow on top of frozen ground, its going to be real fun trying to fix a problem.

Re: Don't feel sorry for them -the lines should be underground!

Doesn't seem to stop anyone around here from effecting repairs. Average temperature below -20C in winter. Frost line IIRC is 6 feet.

All the newer areas, both residential and commercial, in our city have buried power lines, telephone, fiber, etc. Nothing on poles.

In areas where the poles are in need of replacement or relocation, they often just bury the lines. Directional drilling contractors are definitely keeping busy!

because the poles are already there? and that is the available ROW. remember that most of this country was built before underground was a viable option outside of cities.

most new developments are buried but it would be far too costly to refit every single ROW to be buried. also some places the terrain makes it impossible.

power lines are normally only dangerous when mixed with idiots.

I'm gonna go out on a limb and guess you have no idea what-so-ever as to the cost of trenching all those lines that are overhead.

You, sir, obviously have no idea of the cost of putting power underground. For telephone cable more than 15 years ago, the going rate was around $5 per foot and was at 24 inches. Power needs to go deeper so increase the cost.

Feel to write a check though.

Capex for buried lines is maybe 5x what aerial costs. Are you willing to see your electric bill go up by $50 per month to finance putting your wiring underground when there's perfectly good aerial plant available?

I would not call it perfectly good.
I think most people would be willing to pay an extra $50 a month if it mean no above ground wires which also means no stupid reasons for power outages.

In areas with underground wires, during bad stores I never lost power. Any other neighborhood around with above ground wires would be out.
Back in 97 the chicago area had a really bad snow storm. My house with underground wires saw 5 hours of outage while above ground wires saw a few days to over a week with outages while it was 0 deg F outside. It is worth it to bury the lines.

Depends on where you live.

Here, power goes out very rarely. Then again, right now everyone around here would LOVE for a hurricane to rip everything up. Means we'd actually get some water...

Power in my 30-year-old neighborhood is buried and it still goes out. They just dug a six foot hole next to my driveway to patch the underground wires. Apparently the insulation had failed and permitted one of the underground high-voltage loops to arc and it melted a section of cable.

I agree that there should be fewer problems but it isn't problem free. I've owned this house for 10 years and this is the second place in my yard they've had to conduct this type of repair. They have also trenched other parts of the subdivision and completely replaced large runs. Apparently the PSC has rules in place that govern how many times power can go out before they expect the power company to improve the transmission lines. So far this year, I've only had one outage longer than a few minutes but in past years, we've been out several times a year for more than half a day.

Have you even bothered to look at how many lines are out there from various companies? Not to mention all the lines from various companies that have been buried? I'll have to say no on your part considering you really think it's feasible to bury everything.

redundancy, much?

putting all your route eggs in ONE basket is stupid..
also, when it's not clearly marked and published, you get what you deserve....

these jokes seem tailored to deploying fiber in the south, huh...
I always wondered why rural folk weren't as interested in having companies have right of way over their land to deploy fiber.. now you know. Still, it's quite possible that rights of way could be negotiated with the federal highway system for their land access rights.. dont' forget, the land they bought to build roads don't ONLY include just the pavement you can see, but a margin for expansion & infrastructure too in some cases.

For certain parts of a network it would be ridiculous to have multiple routes, others do have them and for good reason. I know my uncle has a hard time when he does digging around roads because they usually let him know there is fibre there, just not how deep. Guess what happens to his job if he hits a line of fibre?

In some cases fiber does go along interstates...pretty sure that's the case with a local telephone co-op's long-range span. Though some of the glass runs along US and state highways because not everyone lives within five miles of an interstate.

As far as putting all your route eggs in one basket goes, that's why you build a fiber ring...cheaper than two redundant paths but you can still fail over when needed. Also, some places are uneconomical to have a diverse fiber route to...

The study forget the illiterates!

Several years ago a new data center in South Florida lost all telephone and data service. Why? Although the company, at great cost, had two terminal rooms constructed on opposite corners of the building. Management had posted bilingual signs at each location where the cable entered the building, warning anyone digging in the area to call building maintenance before proceeding. The illiterates replacing some irrigation lines cut both entrance cables with a ditch witch about 6 inches from the wall. In many cases laborers cannot read warning signs indicating that there is a buried cable or recognize the purpose of a warning tape installed a foot or two over the actual cable.

Put a light outside layer, and then on the inside of the light outside layer, fill it with cyanide.

Then the layer after that is super strong.

The thing that doesn't make much sense here is that L3

The thing that doesn't make much sense here is that L3's fiber is largely(if not all) backbone, which is usually 99.9% underground (only last mile, temp or otherwise IMPOSSIBLE runs are left above ground)
I could understand them having buried Row encroched on, but they shouldn't have alot of aerial stuff to be damaged.
Me thinks the author took some popular stories and presents them as his own/L3 own problem.
Funny, but not really accurate.

Re: The thing that doesn't make much sense here is that L3

Given the fact that this is coming from the L3 blog AND he states that the single most common cause is construction companies not calling before they did. I think it's pretty accurate. Remember, not calling before you dig cuts underground cables which is EXACTLY what you would expect to be their number one problem given how much of their fiber is underground. So when he then goes onto say that 17% of their outages over the past year were caused by tree rats, I can believe it.

Vandalism

I've seen several occurrences of it at some of my company's sites. Some of them are pretty wild.

In one occurrence, a few people poured a can of gasoline around and under the equipment shack, and lit the gasoline on fire. That's after climbing over a 10 foot high chainlink fence with double rows of barbed wire at the top! Thankfully, the building did not catch fire, due to the steel siding and other fire resistant materials. The perpetrators were eventually caught and prosecuted.

Redundancy

We've had service interruptions four times in the last year that were Level3 "cuts"... oops no, one of those was failure in a hardware component. Regardless, where was the redundancy that would make most of those problems just a reduction in service. Something is not what it seems. Or should be. I wonder what shortcut was taken?

Laying cable

I saw a 'convoy' of caterpillars laying fiber once

Lead cat had like a seriously heavy duty single blade plow racking a groove in desert

Behind it a ways was another just like first, plowing in same groove and I figured it was maybe deeper

Then a third with similar looking plow deal but had a huge spool of cable too that was feeding into the plow blade - and it sort of raked the loose dirt back over gouge

I never saw if they tried to smooth down the disturbed ground but it wasn't tore up that much, considering

They were moving at a pretty good clip for a tracked vehicle dragging a honker of a plow...

Disgruntled ex employees or customers

If, while you lived, you were a digruntled ex telco employee or customer and got reborn as a squirrel after your death, wouldn't you instinctively just love to gnaw on them telco wires between poles knowing you are causing the telco lots of trouble ?

The lesson here is for telcos to treat customers and employees well today if they want future squirrels to stop gnawing on their cable plant.
