if anyone wants to no about gigbit routers

[mimp]

Talking of gigabit ethernet, has anyone made a gigabit wireless modem/router yet?

What i mean by that is a wireless AP, gigabit wired router + ADSL modem built all built into one box. Loads of 10/100 wireless modem/routers about, but not been able to find one with gigabit. would save on the clutter..

gigabit = 1000

normal = 10/100

my gd lan works fine through cat5-e cable and a linksys gb router

ok lets iron this out.

Cat stands for category. Every one seams here seams to know a little about each and i think i need to iron ouot the differences.

CAT-5 is rated to 100M

CAT-5e is rated to 350M

CAT-6 and CAT6e is rated to 550M or 1000M depending on your source

CAT-7 is supposedly rated to 700M or presumably 1000M

Today there is no approved CAT-6 or CAT-7. While some folks are selling products they call Level 6 or 7, there aren't even specs for them, making CAT-5e the best available option. CAT-6 cable is being made with 23 guage conductor wire as opposed to the slightly smaller 24 guage for CAT-5e and also has a separator to handle crosstalk better.

Both CAT-5 and CAT-5e have 100 ohm impedance and electrical characteristics supporting transmissions up to 100 MHz. The differences between CAT-5 and CAT-5e show in all aspects of performance: capacitance, frequency, resistance, attenuation, and NEXT. CAT-5e components were designed with high-speed gigabit Ethernet in mind. While CAT-5 components may function to some degree in a gigabit Ethernet, they perform below standard during high-data transfer scenarios. CAT-5e cables work with ATM and gigabit speed products. Simply, if you are using a 100Mbps switch, get CAT-5e cable instead of CAT-5.

Cat-5e (the e stands for 'enhanced'). CAT-5e is completely backward compatible with current CAT-5 equipment. The enhanced electrical performance of CAT-5e ensures that the cable will support applications that require additional bandwidth, such as gigabit Ethernet or analog video.

So basically:

cat 5 is good for 10/100

Cat 5e is good for gigabit

cat 6 or 7 although there is no official standard for then is basically only any good for long distances and its maintains the chances of loosing data packets on the network

ok lets iron this out.

yer. Maybe I shall because you've made a mess of it.

Cat5 will do 100mb.

Cat5e is fine for 1gb.

Cat6 will do 10gb.

CAT-5 is rated to 100M

CAT-5e is rated to 350M

CAT-6 and CAT6e is rated to 550M or 1000M depending on your source

CAT-7 is supposedly rated to 700M or presumably 1000M

Very true, but M in this case is Mhz and not Mb, as in the frequency down the wire, not the transfer speed.

There's no point in a gigabit router, as there's no readily available SoHo connection that can provide more than 100mb.

 

[PHILIP1193]

M stands for Meters as in 100 meter and 350m meters before you need a switch or hub to boost it on!!!

Gigabit is very readily avaliable like the netgear GS605/GS608 (5 and 8 port respective)

If you are transphering large files around your SOHO network like image/cad/video files then you need it, especially when gigabit is not much more expensive than 10/100mb cards

So i feel i didn't make a hash of it !!!

You wish. There's no way you can have 350m of cat5e without three repeaters, and get more than like 1mbps.

Cat 5e cable does not enable longer cable distances for Ethernet networks: horizontal cables are still limited to a maximum of 90m (295ft) in length. Cat 5e cable performance characteristics and test methods are defined in TIA/EIA-568-B.2-2001.

From Here

Category Type Spectral B/W Length LAN Applications Notes

Cat3 UTP 16 MHz 100m 10Base-T, 4Mbps Telephone Cables

Cat4 UTP 20 MHz 100m 16Mbps Rarely Used

Cat5 UTP 100MHz 100m 100Base-Tx,ATM, CDDI LAN

Cat5e UTP 100MHz 100m 100Base-T LAN

Cat6 UTP 250MHz 100m 1000Base-T LAN

Cat7 ScTP 600MHz 100m 1000Base-T LAN

I think you made a hash of it.

And why have a gigabit router when you can get a gigabit switch for 1/3 the price, and then just add the router to the switch?

lol it even says it in the source where you got your first post from.

What are the maximum lengths for cables?

For Solid UTP:

Fast Ethernet 100baseT 100 Meters (328 feet)

Twisted Pair Ethernet 10baseT 100 Meters (328 feet)

Recommended maximum lengths for Patch Cables made from stranded cable:

Fast Ethernet 100baseT 10 Meters (33 feet)

Twisted Pair Ethernet 10baseT 10 Meters (33 feet)

well on the cable it says gigabit

CAT5e is fine, just remember that you can only have 100 meters per segment.

Edit: Sorry kinda been said by the time I posted.
