400G ER4 wavelengths - two grids
by Joel Busch 29 Nov '25

29 Nov '25

Dear colleagues I have come across a weird mishmash of offers for QSFP56-DD 400G ER4 and ER4 lite transceivers in the market, and now I'm looking to compare notes. It seems to me that there were two separate development trains going on at once. Resulting in two incompatible grids of four wavelengths being used (and sold, see below): - 1295.56 nm 1300.05 nm 1304.58 nm 1309.14 nm - 1304.58 nm 1306.85 nm 1309.14 nm 1311.43 nm Why you would go tighter seems obvious to me: To stay close to the zero point of dispersion with all four lanes, and perhaps to make all four experience more similar levels of dispersion, to make dispersion compensation in the receiver easier. It seems that the wider spaced set is based on IEEE802.3 clause 122 (added in IEEE802.3bs), more specifically in Table 122–6 "200GBASE-LR4 and 200GBASE-ER4 wavelength-division-multiplexed lane assignments". (Note that it doesn't officially specify 400GBASE-ER4, this was apparently added in the 50G-per-lambda-time.) The tighter spaced seems to be based on the 100G Lambda MSA specification called "400G-ER4-30 Technical Specification 1.0" specifically Table 2-1 "Wavelength-division-multiplexed lane assignments" [0] FS.com and Fibermall sell transceivers with the wide spacing [1][2] Flexoptix sells transceivers with the narrow spacing [3] According to a contact at one of the shops the wide spacing is also called LWDM and the tight one is called nLWDM. Both now exist and are out there, so caveat emptor, I guess... Does anyone have any parts sourced directly from a router manufacturer? Could you share what they went with optically? Or any other pertinent insider knowledge? :-) Best regards, Joel [0] https://100glambda.com/specifications [1] https://resource.fs.com/mall/resource/qdd-er4l-400g-data-sheet.pdf [2] https://www.fibermall.com/sale-461143-qsfp-dd-400g-er4-lite-lwdm4-30km.htm [3] https://www.flexoptix.net/en/d-164hg-30-e.html?option875=1 -- Joel Busch, Network Engineer Switch, AS559

CAMTEL leaking 4/8 and 8/8
by John Kristoff 21 Nov '25

21 Nov '25

CAMTEL (AS15964) has been originating routes for 4.0.0.0/8 and 8.0.0.0/8 for awhile, which Telxius Telephonica (AS12956) seems to be accepting and relaying to anyone else who will listen. There are some more specific prefixes for much of the covered space, but not all. Presumably a fair bit of traffic to that unused space is reaching Telxius/CAMTEL and some seems to be looping. I imagine AS 3356 might wish to see these announcements cease. I tried a few listed contacts for 12956, but if anyone has a better path to reach out to someone it might be helpful. John
