Are there UTP cables specifically for outdoors, exposed to the sun, rain and other elements? Or can I just use ordinary Belden cables instead?

If its possible, you can protect it by running it through PVC pipes (orange).
Yes there is but not sure if its available locally.

meron po n'yan sir, shielded twisted pair (STP)
kadalasan black ang color.
across the street?... may maximum effective length ang cat5 cable (in terms of signal strength) using standard switches and hubs... (i'm assuming you are trying to extend your physical network to another branch of office na nasa tapat ng bahay or existing office... )..
di ko ma recall ilan meters ang maximum.. that is total length including all twists and turns... gano kalapad ang street na tatawirin? may sidewalk on both sides?
pag hindi pa maayos ang gumawa, there's a chance na pagkalatag ay magkaproblem sa network (hindi ma maximize yung bandwidth na dapat designed for cat5 or cat5e)... hindi pa kasama yung possible easy wear and tear (cat5 itself is not meant for outdoor hot / cold / moisture conditions) so baka before you know it, sablay na network signals mo...
if ok with you, would you like to share ano plan tlaga para makapagbigay ng inputs ang mga techies dito what would be the best and cost efficient solution for your application...

Tanong ka ng CAT5e Solid Outdoor UTP kung meron boybi, black ang kulay ng insulation nyan. Kaso max 100m ka lang pero sa practice namin eh max 80m.
IMO very risky during electrical storms plus CAT5 Ethernet is limited to 100meters.Try searching for self-supporting CAT5 STP. Using STP needs good earth-grounding to protect your equipt.
An option for low-cost diy is by using tie wire as messenger-wire then lash your UTP. This will protect your ordinary UTP from mechanical stress.
Best options for outdoor is to use modem or media converter like:
FE to fiber (static proof)
FE to SDSL (or any DSL tech utilizing ordinary twisted pair)
FE Point-to-point radio or infrared
100 meters nga chief as the above post mentioned. After that a repeater will be needed to extend the signal.
An alternative would be to rely on a wireless router plus a wireless repeater. If it's just across the street, just make sure the wireless router can provide ideally 3 bars worth of signal to the repeater on the other side. Kung less than 3 bars just run health checks and see if the reliability of the connection is still good on the other side. Not the best option if transfer speed and stability's a concern but easier to setup and discontinue whenever needed (as opposed to crossing wires from a post and back then remove them after and replace them all over again and such).
Pero kung wired talaga, may nadaanan akong tindahan before na nagbebenta ng STP sa Carriedo, ain't cheap though and again length limits apply.
dati may nag-suggest sa'min to use RJ45 to BNC then yun ang tutulay sa labas yun BNC cable then BNC again to RJ45. i'm not sure how it is converted pero puwede daw yun
Delikado kasi sa Lightning or electrostatic ang mga outdoor wired devices. Kahit hindi direct hit ang lightning, basta within vicinity ay nakakasira din ito. Sayang mga ethernet devices.
Kung almost same price ang magastos mo sa wired and wireless. I prefer wireless. Safe ka sa Electrostatic discharge, mechanical and environmental stress sa wire installed.. No more worry.. just enjoy the connection.![]()
Currently naka wireless network ako. Pero di kaya mag stream ng HD content using wireless. G lang kasi mga routers ko.
Mukhang mahal and delikado sa lightning kapag gagamit ng outdoor cable. Kakayanin kaya if I'll upgrade my routers to wireless N?
Ganito setup ko:
Modem --- wifi router >>> <<< wifi router --- UTP cable to computers.
The better option is to upgrade to WiFi N but you have to make sure you get 300mbs and not the lower 150mbs wifi N system.
And remember, even with wifi-N, speed decreases with signal strength.
At my home, even my wifi-N setup occassionally pauses/lags with blue-ray/hi-def videos. I am thinking my bottleneck is my LAN.
BTW, although the wifi-N runs at 300mbs, regular LAN only maxes out at 100mbs unless you are running a gigabit lan setup.
I think 100mbps is already enough to stream HD content. It's my setup at home and I can watch HD video using WDTV connected (wired) to my home network.
borrow a friend's wireless-n router and test it.. if it works then you can buy one.. if bottleneck then i think you have to settle with STP cables![]()
If you're gonna get an N, make sure it's the 300mbps type.
Asus and Edimax both have Gigabit 300mbps N routers. You can also upgrade its antennae to high-gain type.
