Grädden connects to Måttgränd's 1 Gbps network

We have joined forces with our neighbours and are expanding our network to almost twice the size (about 100 houses) and ten-folding the capacity of the uplink, from 100 Mbps to 1 Gbps.

Currently we are having our internet traffic via Bredbandsbolaget and our IP-telephony via Alltele (see other pages via the Back button).

I got a call from England on Saturday from a genleman trying to construct a network in Ghana. I told him about how we built our network (he found me via this page) and about the current expansion and the new technology they are using (thin hose-like tubes to each house and blowing of the fibre to each house).

I promised to take a few pictures of the current process and get some info on what kind of equipment to use (fibres, switches, converters etc.) and that combines excellent with my strive to keep this page updated (it still gets a handful of visitors each day).

This is what their Project Manager Torbjörn Tjärnhage wrote:

Hej Tomas,

Vi har lagt en Fibre Flow kanalisering från Emtelle
4 st single mode fibrer till varje hus. 2 kontakterade 2 lämnas för framtida
bruk (TV eller vad det kan vara)

Orexis FTH-3 mediakonverter (100 Mbit) i varje hus (www.orexis.se)

Cisco Catalyst 3550 SMI 48 portars kopparswitch + Orexis
(För så få anslutningar lönar det sig inte att ta en fiberbaserad switch som
klarar Single mode direkt.)
En 1 Gbit upplänk för Internetacess + en 100 Mbit uplänk för telefonin till
er + 8 okontakterade fibrer för framtida bruk.

UPS för elfiltrering.

Varje hushåll får själva installera en terminaladapter för telefoni eller
"tripple play" efter Mediakonverteraren.



In translation they are using Fibre Flow from Emtelle with 4 single mode fibres to each house, whereof 2 have contacts and 2 are left for later. They are using Orexis FTH-3 fiber converters for 100 Mbps.


Cisco Catalyst 3550 SMI 48 port copper switch and an Orexis media converter rack, since fiber based switches are too expensive for the number of users.

They connect to our network via an 1 Gbps uplink and an 100 Mbps uplink for the IP telephone. They are leaving at least 8 fibres for future use between our centrals.

UPS are used for filtering of the electrical current.

Each household gets a fibre converter and behind it, they can install tripple play adapters or IP phone converters.


This is where the network is located (click to get the dynamic page):

One of the mini excavators roaming the lawns...

Small ditch for the fibre.

(one more picture of the access road)

...it continues here...

...ends up in this bucket...

...and delivers fibre optics to these houses. If you look carefully, you can see the green hoses waiting to get fibre optics installed later this summer.

A drum of hose of some kind.

Here's the bucket again.

Pretty unique wagon for transporting hose!

The houses on the left are also connected.

Already almost no sign of the digging!

Close up of the contents of a ditch...

...leading towards the central (inside the house on the right).

This is where the central will be located.

Rolls of hose waiting to get to the central.

Huge drum!

A few more houses connected by this network.
