Not much different. Fiber cables are usually more flexible
than coax. Easier to pull. They use kevlar for strength,
but still can break. Fiber really doesn't like tight bends.

Howdy,
Regarding the breakage issue, I think we would be fine. The
underground conduit was properly designed for the purpose
and has only smooth curves.
Regarding the spelling:
I am US based, and on this side of the pond it is
"fiber." 'Sorry for any confusion.
All the best,

Only if you're not in the U.S. ;-)
Seems that the Nat'l Institute of Standards and Technology, a part of
the U.S. Gov't, uses the term fiber extensively.

Of course. Despite what they might think, most of 'us' are not in the |
US.
Also, you can get by in most of the world with English, not American.

There is a difference. Just listen to George 'Dubya'.

Not as big a difference as there is between "the Queen's English" and

That's because there is only about 20% difference in the 'speed' between |
the two mediums. - Unless you wan the same electron out, as you put in.

The lowest-tech fiber you can still buy is an old 160MHz/km-bandwidth
multimode 62.5/125 micron, which is going to support 2000 meters at
100Mbit/s, so 600' are not a problem at all. There are even older types
available exclusively from eBay's surplus dealers, such as 100/140 micron
multimode fiber. No matter how cheap, don't even think of getting these:
no way to buy connectors anymore. Anything relatively recent would be for
125 micron outside diameter.
The costs hugely depend on the type of jacket the cable is going to have,
not so much the fiber itself. The OP did not specify the environment, but
I think it would be wise to install an indoor-outdoor cable with at least
4 fibers (though only two will be utilized right away) or, better yet, 6.
It would probably run you roughly 50 cents per foot. Plus installation.
Expect to pay anywhere from $50 to $75 per connector if you hire a pro.
Very small job, so per-item costs are going to be very high.

These guys are as "economy" as it gets to the best of my knowledge, but
don't take my word for it - do a Google search:

Both are designed to support up to 2000 meters (6560 ft) on "regular"
multimode fiber. At this point in time there is no price difference
between 10 and 100Mbit/s (if you can still find 10, of course)
Good luck!

Hi Dmitri,
OP here...
I need to pull cable from the second floor of a building
through a (properly designed) chase, then through a
(properly designed) underground conduit for about 400 feet,
then through a chase into a second building. We currently
have 10-Base-2 and want to up the speed.
Your specific suggestions, and rough cost estimates, based
upon the information I have provided would be most welcome.
Sincere thanks,

Howdy,
I have two systems that are about 600 feet apart.
They are currently connected by (and forgive me if I don't
have the proper name) 10-Base-2 with BNC fittings running
underground between two buildings.
This cable was chosen over Cat 5 because of the distance.
As currently configured, the net between these two systems
runs at 10 Mbps and that generates a few questions:
Are there faster alternatives in our situation? Are there
faster alternatives that could run over the same cable?
Specifically, might our current speed limitation be caused
by the cards we use? Might there be cards available that use
BNC fittings on such cable but run at higher speeds?
We would be interested in increasing speed at reasonable
costs and could certainly run another cable if that were the
way to go. I will add that I have used our current setup for
about four years and except for the speed, it has functioned
reasonably well.
Replace the cable with fiber optic cable. You'll then be able to run 10
or 100 (or more) depending on the media converters you use on the ends.
We use a lot of Milan converters, but there are many other brands that
work as well.
http://www.milan.com/converters/fast_ether_conv.html
shows some of their products. The stand alone Classic Converter lets
you plug into anything with an ethernet port. But I see what looks like
cards that go inside the PC, which might be more convenient, and
cheaper.
Sincere thanks for any suggestions about this,

Hello again, OP here,
Ah, technology...
I have contacted several folks who install this sort of
cabling and have informal quotes from $800 to $4000.
Perhaps I am missing something, but...
If I were to get appropriate cable, have it assembled with
appropriate end fittings, and plug each end into an
appropriate media converter it would seem that the job would
be done at a cost significantly below the lowest estimate I
have received.
Is there any (real) reason that I could not do all this
myself?
Sincere thanks,
--

There is a certain amount of expertise that is required, but if you are
careful and can spend literally hours feeding the cable through the
pathway, there is no real reason you can't do it. Normally a company
would send a crew to do the job, somewhere between 2 and 4 people. The
minimum would be two who have experience, three if one is truly
experienced, and four if they have some experience pulling copper but
not necessarily fiber.
If you are going to do it as a DIY project, then you will need at least
two people. One person to feed the cable from the first end point down
to a second person where the transition will be made to conduit. Once
the cable is down the chase, then that person would feed the cable into
the conduit while the other does the pull. When that section is
complete, move the people so the pull up the last chase can be
completed.
You may want to invest in a bottle of cable lube to dress the fiber as
it goes into the conduit as it already has cable resident. It will
relieve a lot of the stress.
Oh, you will definetly want to buy/rent a cable pulling grip for the
pull through the conduit. If you put strain on the connectors, or even
too much strain on the fiber jacket itself you will damage the cable
and it will be useless. |
