If 1Gb/s is already here, then why isn't 10Gb/s possible soon?

@EindeutigerUserName so why spend more money if 10 Gbit/s is not faster than 1Gbit/s.

The speed test server shows you 10 Gbit/s, but that’s it.

I’ve had 10Gbit/s for several years. But I have not yet found a provider that offers 10Gbit/s for its application on the WEB 10Gbit/s.

The AWS cloud offers the option of a direct access connection of 10 Gbit/s, but this can be easily paid for at a few 1000 CHF/month.

The OLT is connected to a maximum of 2×20 Gbit/s in the backbone with >64 participants.

This is also the case with Fiber7 because they mostly purchase the services from Swisscom wholesale.

@EindeutigerUserName

The 10 Gbit/sec with a Swisscom XGS-PON Anschluss is a shared medium for up to 64 parallel users.

From a technical point of view, this requires an optical splitter in the headquarters, which simultaneously forwards the same signal to the customer group at 10 Gbit/sec (and each customer router then extracts the share intended for itself).

If there is no slot available on an optical splitter in a control center, then XGS-PON cannot be activated yet.

But it’s only a matter of time before you will also be switched to XGS-PON, because for Swisscom this means lower costs at the headquarters and completely independent of the subscription you choose.

XGS-PON is therefore a cost-saving measure compared to a P2P-Anschluss directly to the “backbone” and that is why Swisscom no longer offers your existing AON-Anschluss (AON = Active Optical Network, also known internally as BX) for private customers .

It’s only available for companies, or at Init7 and a few others.

In practice, it doesn’t make a big difference for the individual customer, because even if you have to share the 10 Gbit/sec with up to 63 others, you will usually receive well over 1 Gbit/sec for your router, because the Most customer routers are always idle with very low bandwidth requirements on the XGS-PON tree, and conversely the personal 1 Gbit/sec with the current Swissom-BX is also more than sufficient (except Speedtest server) to serve every possible server on the Internet up to the performance limits of the external server.

@EindeutigerUserName I’ve never managed this, except with GoPro with 1 Gbit/s upload to the video server.

It’s clearly a chicken/egg problem.

Back when 1 Gbit/s fiber from SC was first available, only 200 Mbit/s was possible from the fastest provider.

Even with multi-connect connections it doesn’t get any faster, I’ve already tried everything.

Please believe me, without “Ischasgriff” 10 Gbit/s is not possible, even via VPN to a colleague who also has 10 Gbit/s.

A maximum of only 8 Gbit/s is possible because of the check bits.

Discussion about 10Gbit/s connection and the technology behind it.

Unfortunately there is no SC-TV on SC-Internet, otherwise I would be directly at Init7…

Blue TV works with every internet provider. Either via the TV app on a current smart TV, or on an Apple TV box, also with the corresponding app.

Sure, not quite as easy to use as with the TV-Box von Swisscom, but it works.

The plan is to expand the headquarters in 2024 (no PON equipment there, OMDF needs to be converted, etc.). Exact date is not known.

@kaetho Yes, yes. As I understand it, however, you need an SC-TV contract and that doesn’t exist without an SC Internet contract… which you would then simply not use, but pay for. Not really attractive either…

Important, there are blue TV and blue TV Air

- blue TV with the UHD Box, Swisscom Box, Box 21 or Box 5 is only available with Swisscom Internet.

- blue TV Air (pure app solution), however, can be used with any provider. Even without Swisscom Internet. There is TV Air free (without recordings, without replay, without reels) and TV Air (10 per month) with a bit of memory for recording (60 hours and 30 hours replay but completely without reels. Also important, yourself If you subscribe to additional packages such as SuperMax, Premium, Sport you do not have any rewinding because replay is only allowed for 7 days.

I personally think you have to be a bit masochistic to use blue TV Air. It’s still possible on a tablet, but on the TV with a channel list of 200 channels, scrolling through to the last channels becomes torture.

64 customers sharing the 10 returns? 😂 You dreamer, you. There are probably several thousand customers. For so little money you won’t get dedicated fiber, just “best effort”.

(Viewer discretion advised: The following numbers are assumptions and may in reality be different depending on occupancy, uplink speed, etc. The exact interpretation, especially overbooking, are closely guarded trade secrets of the respective providers.)

So:

• >=32 customers per splitter
• Each splitter hangs on a port on the OLT
• >= 16 ports per line card in OLT
• >= 12 line cards per OLT
• Uplink on the OLT: maybe 2 × 10 Gbit/s or if you’re lucky 2 × 25 Gbit/s
• Connection of all other OLTs to the core network of Swisscom, Salt and Co.?
• Peering into the “Internet”.

Here is an OLT: The inserts or Everyone can count line cards and the individual ports themselves. In the middle is the uplink of the OLT.

@millernet

Of course, every network node is overbooked by dimensions, and the idea that you can access any server on the Internet using the speed available locally at your own Anschluss without an exclusively rented direct connection is of course also absurd.

The maximum of 64 group participants in a Swisscom it because, unlike in your picture, according to information from Swisscom technicians, Swisscom does not use 32, but 64 splitters. 🙂

to shit tüpfli:

Strictly speaking, there are always 2 splitters:

1:2 and then 1:32 or

1:4 and then 1:16

It has the advantage that you have to split it into many individual fibers very close to the customer (sleeve or BEP).

Incidentally, this also applies to the energy distribution (electricity) of buildings/districts.

Here, too, “simultaneity factors” are taken into account.

This means that it is assumed that not all households are using their power lines to 100% capacity “SAME TIME”.

Proven, calculated factors are assumed. The same applies to data supply infrastructures.

Of course, there can (rarely) be situations where things sometimes get “tight” - but this is certainly the exception and not the rule

Incidentally, this also applies to the energy distribution (electricity) of buildings/districts.

It’s a shame there are no flat rate tariffs there LOL

I believe the variant you are describing corresponds exactly to the construction method that was banned by the Comco about 2 years ago 🙂

Currently, optical splitters are no longer permitted decentrally on the last mile to the customer, but only in the headquarters (CO) 🙂

Don’t get upset 😁 1:4 and then 1:16 are in P2P in front of the OMDF.

Splitter cassette in BEP

We no longer build splitters into the BEP… and existing ones are replaced with normal splice cassettes for P2P.

Thanks for the pictures @user109. So according to the picture

*OTO
*FD

• BEP
  *Drop
• Street cabinet / manhole
• Feeders
• POP / “Central”
• Splitter OMDF: 16
• Splitter before OLT: 4
• OLT Port: 16 ports per line card
• OLT line card: 7 line cards per OLT (installed 3)
• “Uplink” OLT: 2 × 10 Gbit/s (I’m assuming a LAG now… although the LED on an uplink doesn’t light up at all.)
• Aggregation OLT per POP:?
• Connection to core network (routing etc.):?

This results in an overbooking between OTO and aggregation in the core network of:

• According to the picture with 3 line cards and 2 × 10 Gbit/s uplink: 16 × 4 × 16 × 3 × ½ = 1:1536
• with 7 line cards and 2 × 10 Gbit/s uplink: 16 × 4 × 16 × 7 × ½ = 1:3584
• Full expansion with 7 line cards and 8 × 10 Gbit/s uplink: 16 × 4 × 16 × 7 × ⅛ = 1:896

So: Depending on the configuration, several hundred to several thousand customers 1 × 10 Gbit/s or approx. 8.8 Gbit/s net 😁.

And yes, in practice this will work:

• Simultaneity factor
• Only a few customers are speed test junkies and even know how fast their Anschluss is.
  *Not all customers have 10 Gbit/s as a service profile.
• Customers with 2.5 or even 10 Gbit/s equipment or Network are also rather rare.
• Most devices are connected via WiFi. In practice, gigabit is already the highest feeling there.
• Everyday applications, even large game downloads from XBox, Playstation or Steam etc. reach somewhere at 1 Gbit/s. With XBox and Playstation you’re more likely to get less than that and if you’re lucky you’ll get maybe 500 - 800 Mbit/s.
• The “bandwidth” or Data transfer rate is only one quality criterion of an “Internet connection”. Latency, jitter and packet loss rates are much more important.
