FTTP splitter markings

So, a couple of fibre splitters have appeared on poles near to us in the past month, each having writing on them. The nearest one is pictured below. I'm guessing the writing means something to someone, but what?

The exchange is SWLKD so I guess that's the "LKD" after FTTP on the third line.

Any advances on the rest?

The I may be 1

Have a look at this splitter node, you can see some similarities in the markings.

All the splitter nodes I have ever seen the ID always begin 'TS', but maybe thats a local thing to here.

I have uploaded their image onto my server here (JPG) or here (PNG) I think that's FTTP and not a Splitter Node, but I might be wrong.

Top line probably refers to contractor/engineering ID.
Two up from the bottom is an internal "estimate" number for the job to install the equipment.
Last lines are the contractor that installed it CT Carillion Telent and BNE Barden Network Engineering.

How many premises does each one of these serve?

The reason I ask is that of the two mentioned in my original post, one is here, and the other is two posts along outside the next property along the road in the direction seen on the map.

I can't imagine that each property will have one each so what geographical radius or line length would each one serve?

Yeah exactly right. Fourth line down is the Optical Network ID "ON". That just the unique ID for the fibre circuit in the system.

or line length would each one serve?

I suspect you may have misunderstood something, this is FTTP, nothing to to with line length at all.

The 'next one down' as you put it might be a DP node rather than a splitter node.

Yes, I know that it's not like copper but was thinking more along the lines of how long a fibre line can be before it needs connecting with some hardware that requires power or what not.

The 'next one down' is the photo in the OP.

Both boxes look the same but I'll try and get a photo of the one on the post on the map later.

When the kit is pole mounted the housing is the same for splitter and DP nodes.

Openreach's FTTP is GPON and is passive so no electric powered hardware needed between exchange and property.

It all depends on how many splits and chains in the fibre is needed to cover the number of properties/area.

Thanks.

Is there any loss when two lengths are connected, say to connect a distance longer than the length of one length of fibre?

Any fibre joint carries the risk of loss, but this is measured and deployments are planned so that there is no loss of useful signal at the distances involved.

FTTP/FTTH is essentially a fixed connection speed service rather than the variable connection speed services of xDSL
