Installing Fiber Instead Of Cat5?
Jul 31, 2011
I have a question relating to installing lines underground in a conduit.
We've had several lines get hit by lighting which leads to the line being bad, equipment being damaged and so on. We've then installed a new cat6e cable WITH lightning arrestors which were blown almost instantly on the first storm. This is obviously a bad ground issue, and a risk to the equipment.
This being said, I would like very much to run fiber optic cable in this conduit and then convert it to ethernet, but I don't know if fiber is susceptible to lighting like ethernet cable is, OR if there are other methods to prevent this freak of nature crap!

Prior we only had 62.5u multi mode.I've got 3750x switches and new SM SFP and yellow fiber patch cables. None of my links show connected. No lights and trunk port interfaces show down/down.
Is there a special command you have to do on a port when using SM fiber? Do you think I need cross over fibers?
Also, should I be able to see a laser signal light like MM or is SM a different frequency so it's not as visible as MM?

The reason I want to do this is to connect a DSL modem. I'm moving all my networking equipment to my utility room where all the cables come in to the house. All of the phone jacks are wired using Cat5. So, I want to take one of those Cat5 cables and terminate it with an RJ-11 so the modem can dial out.

I have CAT5 cables run throughout my house to a few different jacks. They plug into my modem downstairs. I want to hook up my desktop internet through one of the wall jacks upstairs. The wall jack has CAT5 cable run to it but only accepts telephone wire sized jacks. How do I connect to the internet with this setup?

I have a new house in which I have installed my cable modem and router in my storage room basement. The (4) phone jacks in the house are wired with CAT5 that runs down to my storage room. I would like to use Vonage and keep it in my storage room with the rest of my network. How would I configure Vonage with what I have described?

I was recently tasked at work to reinstall phone lines after a remodel. We have 2 phone lines with two phones and a credit card machine. I ran into a piece of equipment and I have no idea what it is so my research into the subject has been halted.

I am installing a network in my small business and was given a spool of Cat5 cable to run wires... I know the length in feet of cable that I was given, but I was wondering if there is some kind of markers on the cable to tell me how much is left... I will be charged for it by foot after I'm done, and I want to know how much I've used. Do I have to just use a measuring tape? Seems unnecessarily complicated... I've checked the wire but can't see any marker of the length remaining.

When I vacation in Florida my neigbour across the street gives me her wep key so I can use her internet. I have to sit by the window in order to get a signal. I purchased the range extender and set it up with her ssid and wep key I ran cat5 from that into the house. If i use the cat5 on a laptop it works fine. When I run the cat5 to a linksys router and use wireless it fails I can connet to the wirless router but no internet.

I have a computer that is directly connected to my internet broadband service via my router and modem. From that computer, by use of a router (of course), I have a wireless connection to another desktop computer in my home, about 90 feet away.From that remote wireless internet broadband connection, I'd like to connect to yet a third computer. That third computer will be 200 more feet away. I have a direct Cat5 wire from the wireless computer desktop to that point 200 feet away. I'm thinking of adding a computer at that point.So, that raises my question: Can a computer receiving a wireless signal, then relay or transmit that signal to another computer that is "hard wired" to it via a Cat5 wire?

I have a Linksys/Cisco wireless router. For the purposes of a high def throughput, I have a wired connection from the router to a Windows Media Center appliance in a separate room.However, now I have a second media appliance (Roku device) that I want to run in a wired fashion as well. Here is the thing, I don't want to run a second Ethernet line from the router to new roku device. Is there some way I can share the existing ethernet line between the roku device and the media center appliance? Ideally, since the two devices would never be used at the same time, I was hoping some other network device (another router?) could be hooked up to split the line between the devices. Worst case, is there some simple splitter I can use? Obviously I am trying to avoid the worst case scenario: switching the ethernet connection manually between the two devices every time I want to go from one to the other.

Is there an easier way to connect an RJ45 connector to a Cat5 cable, rather than the traditional method of lining up the wires by hand, inserting them in the right order into the jack, and then crimping it? It just seems like it would be very tedious if you had to do this A LOT, and I've had a good bit of practice. I saw that they make "EZ RJ45" jacks.. but do they make anything else that can make it easier? I'm asking out of curiosity, and not necessity. I have no problem wiring them, but it's just something that I hate to do (I think a lot of people would agree that it's not the most fun thing to do in the world of networking).

I live in a frat and I am currently researching how to design and configure the most efficient network for the house. However, one of the other big problems we have is connectivity of our ethernet cables. We have an IT room with 2 switches that feed ethernet cables to all parts of the house and connect to an ethernet box in the wall where we can simply wire in our internet connection. We have wireless routers too but to keep the bandwidth usage across the WAP's I want to let people use the wired connections. However, many of the connection in the house do not work at all. I plug in my laptop to the wall jack and it gives me the No Internet Access notice. I don't understand why it works in some rooms and not others. All jacks seem to go into the same switches at the other end so I cannot figure out what the problem could be.

We are setting up a network in our new house. We have the internet entering the garage. From there we have a 60 ft Cat 5 cables run through the crawl space. Orginally we had the wireless router attached to the end of the cat 5 and then attached to the computer. We could not get a connection through this wire. We then took out the cable, and ran a new one, same issue. We took the same cable, cut it down to 25 feet, installed the router in the garage and we have an excellant connection. We then ran a new wire through the crawl space from the router. Same issue, no connectivity. Taking that cable out, cutting it down we ran the wires from the router to our computers in the garage. why a Cat5 cable would not work at 60Ft.?

Our wireless router is in a room at one end of the house (beside the telephone point) from which ethernet cables can connect to the Cat5 sockets taking the broadband to the other rooms that have a Cat5 socket. That is fine for connecting devices to the sockets in the other rooms but because the house is old with thick walls our wifi signal fades to nothing in some parts of the house. Moving the wireless router only moves the problem to another area. I thought about a wifi repeater but the room I would like to locate it in to then boost the signal to the rest of the house is borderline on the range for the wireless router. Is it possible to connect another wireless router or device to the main wireless router through the Cat5 cabling so that the second router/device can offer wifi to that area of the house?

Have had ADSL installed through a router, connected the wireless router and it works fine Have since connected the original router via -120mtrs of CAT5 cable to extend to the house. Connection through LAN is fine into desktop however the minute we try to connect an additional wireless router the connection fails. We have even put the LAN from the second Wireless into the desktop and there is no connectivity.We have had a technician come to sort the problem, they advise that they have no explanation as to why the LAN works from the distance but the wireless does not. They have suggested that we need to cut the CAT5 half way and put an antenna up to connect the two routers.

I'm building a security camera system,which can connect to internet to be viewed from away.The camera receiver connects to the modem with a Cat 5 ethernet cable,which results in a cable running across the room. My modem is a wireless type,but the camera receiver only has cable support it seems.
Is there a device that I can use to get rid of the Cat5 cable in this scenario?

Im not going to lie, I'm pretty much a beginner when it comes to switches. I have recently purchased a second hand 3512 XL which I have managed to connect to via PuTTY and the console cable. I have familiarized myself with access privileges and resetting passwords and locating the IP address, etc.
I am trying to connect the switch to Cisco Network Assistant however I am unable to connect to the switch over a cat5 on the first port (nothing else is on the network, just a server directly to the switch). I have tried pinging the switch from my server, and similarly I have tried pinging the server from the switch and each time there is 100% fail rate.

I have a Sony Vaio running Windows 7 Home Premium. Yesterday I accessed the Internet at the office over a Cat5 cable. Last night I accessed the Internet at home via my USB Internet dongle (actually an O2 mobile phone). Today neither works. I have also tried to connect to the Internet via Wireless and that does not work either.Needless to say my desktop (using the same Cat5 cable) works. My mobile phone can access the Internet on it own. And others can get the wireless to work.My Vaio can connect to all three; however, all three say "No Internet access".I changed nothing between last night and this morning. I have scanned through the list of Windows Updates and nothing has been downloaded in the past week. I have turned off my firewalls (in both McAfee and Symantec Endpoint Protection). I have run the three NETSH reset commands with Administrator privileges. I have rebooted my machine numerous times. Nothing works.

I have been doing network and computer work for a small public library which will soon be needing to change internet providers. Our planned route will be to have a fiber connection directly from our local ISP, but we need to figure out the best network hardware to accommodate this network connection.We currently have two HP 1810-24G switches connected to a Sonicwall TZ100 firewall as the primary router. The firewall/router connects to the internet with Cat6 connected to a fiber optic media converter. The media converter is on lease from the current internet provider so it will be gone.Our new ISP has said that they can provide a fiber connection in our building to an SFP port termination, which is their recommendation. Ideally, this would be an SFP port in a router or firewall. However, there seems to be very few options for routers with SFP and they're all incredibly expensive compared to a network switch with SFP. While I imagine we could just terminate the fiber optic connection into a cheaper switch with SFP and connect to that with the firewall, our network is further complicated in that we have a CISCO LifeSize video conferencing system which ideally runs best without running directly through the firewall, which can cause some lag and glitches in the signal it seems. I don't believe it's possible to have the router WAN interface connect through to the ISP with a static IP and PPPoE sign on as well as another network devices using the PPPoE and a separate static IP address, am I correct?Have I just over-complicated this network issue, and everything should just be run behind the existing firewall, or should I be able to find a different firewall/router or switch that can connect with SFP to the ISP?

My carrier is dropping off a single mode fiber on LC connection 10gig port but on myrouter I am using XFP-10G-MM-SR modules. Can I still use a SMF to connect from handoff to this router or do I need a different module?

I am new to fiber connections. We are have a SM fiber comming into our data center. It will terminate with Single Mode SC Unicam connectors in the fiber panel. I want to connect these to a 3760 GB switch using Cisco GLC-SX-MM Gbics. I'm guessing all I need is a SC to LC fiber connection. My question is this; is there any issue going from Single mode to Multi-mode? Do I need an adapter or do I need to find SM GBICS? The distance between the patch panel and switch is only about 10 feet.

I just upgraded my cable modem from the Motorola Sufboard 5120 to the DOCSIS 3.0 capable 6120. Provisioned it with Comcast and their "Blast" service (supposedly it caps at 16 down, 2 up).
I had, in the past, used my desktop via N-format wireless (DWA-525 N-format PCI adapter and DIR-655 N-format router) to do a speedtest.net test. I was getting 16 down and 2 up (as advertised). When I switched to the 6120, I did a speedtest.net test again to see what kind of gains, if any, I was getting. Turns out, I was getting 20+ down (nice improvement) and 1/2 Mbps up (a fourth of what I used to be getting?). Called Comcast. They "sent signals" (don't they always?) and claimed that it fixed it. My download speeds increased a smidge (about 22), but my upload speeds were still .5. Called Motorola, they had me do a few things and now I get 1 Mbps up and 27 - 30 down via wireless.
My download speeds are great. I'm content with that. If I hardwire from the cable modem directly to a ****py old laptop, a speedtest.net shows 4 Mbps up. So why do I get such a high upload speed when hardwired (4 Mbps), but a fraction of it (1/4th) when wireless? I'm not using any other devices to sap bandwidth (some are connected -- i.e. another desktop, my Droid phone, etc., but aren't actively pulling packets). And why would it go from 2 up (on my desktop via wireless in the past) to only 1 up (via wireless now) when the setup is the same across the board (as best I recall) other than upgrading my cable modem.
Since I get 4 up when hardwired straight off the cable modem, I assume my DIR-655 is slowing me down somehow. How to pick up the pace a bit? I've already tried the standard "power cycling", etc.
Oh, and the reason I go wireless -- my cable modem and wireless router are in my game room in the basement for my PS3. My desktop computer (and the wife's desktop computer) are two floors directly above it in our "office". Signal strength is "excellent" ... always has been. And again, pretty much everything is the same.

I have had fiber optics for phone, TV, and internet (30/30 speed). They upped the price 80%! I would like to keep my internet on fiber optics but drop TV and phone to cable which is cheaper. Can I have both systems simultaneously? Also, we have a Sony L-series TV/Computer. IT's a TV and computer in one. Can we have both fiber optics and cable attach to it at the same time?

Besides the color difference, is OM3 the new revolutionary cable type being used now and days? The specs i have seen between the 2 are quite similar, both are 50 microns

When it comes to fiber optics my knowledge is very limited. All I know is that they can carry data at high bandwidth for a long range at blazing speeds etc.My boss has asked me to link several buildings to the network and I am led to believe that joining them through fiber optics to be best since we are expecting a lot of data traffic between.I have done the normal RJ-45 networking with Gigabit networking in my organisation but need your assistance on how to join each of the buildings through fibre optics.Draw up the fiber optic lines from the main building to each building.All the buildings have Gigabit Cat6e cabling and network in each.I am planning on using a single mode media converter to convert the end of the fibre optic to the normal RJ45 connector and plug it to each switch at each of the ends of the fiber optic cable .I don't even know the gadgematics required except for the cables them selves, crimping tools, the media converter. There is about 300-400 metres in between of each building from the main building.Also, I believe that we need to create cross over cables as in the normal way we do in connecting 2 switches.
