using a switch as a network repeater

By trif55 ·

I have a company planning to upgrade to gigabit ethernet, they have a main floor where most of their connections will be used and a second floor where they need about 6 connections,

however its over 100m in cable length to get to the second floor, would a 12 port unmanaged switch support 6 simultaneous transfers at full speed and act as a repeater for those 6 lines?

if not what is the best solution to this problem?

Install a repeater.

I just tried googling "Gigabit Repeater" but can't find any, suggestions/links? I feel I'm missing something obvious here.

Fiber would be the best solution

Assuming you use an Ethernet switch that uses standard GBICs for uplinks, then you would use a ST fiber gbic for a link up to around 550 meters, and a SC fiber gbic for anything up to 2KM.

Aren't fibre cables/GBICs probhibitively expensive for a small company?

I use them at home...

I've been working with computer infrastructure and networking for upwards of 20 years, and if there's one thing I know, is that cutting corners to save money never ends well.

Fiber optic cable is around 75 cents a foot, and the cost to install is probably a couple of hundred. GBICs are less that $100 each, or external fiber-to-ethernet convertors go for ~$100 ea.

yes, it will likely work just fine.

Hi, I briefly explained the situation to our supplier and he said putting more than one line between switches would cause looping, is this true?

a thought....

by ---TK--- In reply to looping?

Say you have a 12 port switch. Port1 goes to the other switch/router device, and all the other ports go to PC's/servers. This situation would be fine.

Now if Port1 and Port2 both go to another switch/router, then yes it would cause a loop.

Adding in a repeater would be fine as long as it repeats only that single line.

The difference between a repeater and a switch is that a repeater will send out a mass broadcast causing alot of unnecessary traffic, all the PC's will ignore the boadcast except for the PC that wants the information. A switch on the other hand will Cache the MAC address of the PC's, and forward on the traffic to the corresponding MAC address.

My aim is to have more than 1Gbs between two main areas of the building (which are also separated by about 200 meters)
