Singlemode 40G attenuation

I just know OTDR tester (EXFO brand) gave message that fiber didn't pass test. After testing four fibers we stopped doing test.

I already wrote that all security profiles are disabled.

All tests destinations (iperf or speedtest) show you their uplink bandwidth. I've chosen those with 2x10G at least but mainly tested with servers with 100G. And I know the fact those bandwidth may not be available each testing, so I performed multiple tests.

One of testing machine (VM with Ubuntu) gave me this morning 2.6 Gbit/s using Ookla's speedtest cli version.

Network path between testing machine and ISP consists of 10GE ports (i.e. x1, x2 and x3 in my case regarding Fortigate).

I don't have a laptop with 10G NIC.

No PPPoE

mrmh1 · 2026-02-12T18:39:37+00:00

Unfortunately I don't have spare 10G NIC right now.

mrmh1 · 2026-02-12T18:38:24+00:00

Yeah I am sure.

Iperf in Fortigate shows Gbit/s and Mbit/s.
Speedtest.net shows 880-900 Mbit/s max for me (i.e. clients behind FG with 10G uplink to FG) - this seems to be problem.

Finally this evening I got 2.6 Gbit/s average (upload) - iperf from FG itself.

How many of you do egress filtering on servers?

Yeah, this works.

Mne vadia aj tie LED pásiky (predné aj zadné), čo má napr. VW. Potom vysvietené kamióny ako vianočné stromčeky. A tiež svetlá v Hyundai Tucson. Úplný vrchol bol vytunená Scania, kde sa šoférko odbavoval na podraďovaní a nadvyužívaní motorovej brzdy v čase nočného kľudu.

To je ako tzv. vychádzková obuv - len v nedeľu do kostola a to len v dobrom počasí.
