Hello,

we are awaiting our 200mbps BT NET Lease Line order to be fulfilled by BT which should be happening within the next Month or so.

i just want to clarify (Since BT are not helpful) that our setup will work.

we have a UDM Pro Router for which we want BT net to use WAN 1 on it as our primary line.

BT have said they are providing an NTE which i presume will be an ADVA FSP150CP ?

i want the connection to go from the NTE into the UDM Pro, happy to connect in what ever way will work, CAT6, DAC, etc.

can someone confirm this setup will work?

The ADVA will by default be provisioned with your connection to it being via the SFP (eg Fibre). The service provider (so BT in your case) can ask for it to be on the copper port if you wish. In your case it won't really make any odds if you're only doing 200 meg.

You then just configure the IP addressing in that BT will presumably provide to you once the line is in, and you'll be away.

Hey, thanks for the reply, annoyingly, we are extremely rural… 10 miles from the nearest Exchange. We’re in the middle of a woods in the middle of no where so they’re laying 15km of cable to us. It’s a pretty big project for them. Yeah there’s a huge upfront cost to it also, because of what we do it’s a must have at this point however so we have no choice and BT are the only company that would do it let alone cost wise… no one else would even bother. So I won’t have 2 firewalls or anything or any problems like that having the Cisco router in place? Is there an option not to use the Cisco router now djist use the UDM and the NTE?

I doubt only BT would have provided it - anyone else that uses Openreach for Ethernet would have - I can think of several companies who would.

The other benefit of keeping the interface optical is that the service between the NTE and router can extend beyond 90+10m limits on copper. Useful if the router is in another building etc for example. Otherwise yes there’s not much else in it.

I mean sure, that's a fringe scenario. You may find however running copper is more power efficient too for a small connection. SFPs can be hungry beasts. Every watt counts!

In terms of power consumption, in my experience fibre is actually very power efficient especially the low power LX variety. 10G copper and pluggable copper SFPs are another matter entirely and yes can consume quite a bit.

Anyhow. To be fair deciding to take a managed router as part of the bargain (or not) is going to have a far more impressive quantum on power consumption than the difference between 1G on copper or fibre interface.

You say this, but with quotes for businesses how hitting £1.04 per unit, every single watt matters…

Somehow this has morphed in an energy efficiency thread...😂

In which case if the object is absolute power consumption - delete the managed router, go wires only, and use a DAC cable between the Adva and customer router.

Apologies for taking this completely off course...

Small margins, but to be honest geeks technology enthusiasts will want SFP+ and the rest including me will be happy with a Cat 5 (or above) RJ45 patch lead 😎🤣

It's a bit of nonsense in this particular case - the difference between 0.5W and 0.8W - yes 0.3 of a watt between a GigE copper port and SFP fibre port. There's probably more natural variation in the basic power supply of the NTE as they roll of the production line

I love a good energy efficiency argument, BUT if your business margins are so tight that 0.3W matters then I suggest other more tangible savings could be made....like not putting in a managed router. A whole box will save a ton more energy than choosing one interface type over another.

...or for that matter taking the microwave out of the lunch room or the kettle. 🙈😂

That aside, no joking, this winter is going to a rough one for lots of folks and a lots of small business will simply stop if the cost of utilities gets increasingly insane.

My comment was around practicalities of simply using a RJ45 copper patch lead over the whole fibre thing for a 200Mbps circuit that may only need to go a few metres. Sometimes people want to over engineer the solution because technology gives them a buzz 😎
