Pleased to announce the publication of the Edition 12 of the ArubaOS CX and AOS-Switch Transceiver Guide.This is Edition 12, published Sept 2022.See the chapter titled "Updates to this edition" for a summary of the changes.Please find the official guide on our asp.arubanetworks.com site, using this link.
(Software and Documents / Switches/ search for "Transceivers")Avoid searching for this guide on Google, as it will return outdated editions.This edition covers support up to the AOS-CX 10.10 and 10.09.10xx releasesThis Edition now covers the new models of the 6300 introduced on Aug 15, 2022, along with the 50G SR optical xcvrs.(BTW: the new 9300-32D switch and new 400G xcvrs and AOCs and 200G AOCs will be covered in the upcoming Edition 13 -- ETA End of October, 2022)------------------------------Ed Kurata, Aruba Sr. Product Line Manager,Switching , Transceivers, Accessories, Power, and other thingsRoseville CA, USA------------------------------
Hi.Just skimmed through edition 12 documents, but did not manage to find information about module "R9B63A Aruba 100G QSFP28 LC FR1 2km SMF Transceiver" (maybe I just missed it?)Special interest if this module is supported in 8360?-Roy
You're getting it;Just as you're probably aware that a 40G SR4 can be split into 4 separate 10G SR connections, and a 100G SR4 split into 4 x 25G SR links,the 400G DR4 (and the eDR4 is just a bit longer reach for 2km) connects to 4 separate FR1 because the split links are of the same technology.Remember too, eDR4 <==> 4x FR1 are SMF (singlemode Fiber) connections.
We don't YET have a MMF 400G SR8 xcvr... and know that one uses an MPO16 connector (see the Corning Guide for examples of MPO12 vs MPO16 connectors).That's why I pointed out that FR1 is NOT compatible with 100G LR4; FR1 uses 2 lambdas per fiber, because it's really a 25G frequency, but since it's PAM4, it transmits 2 bits per transition.BTW: as i mentioned before about not having the 9300 and related interconnects not YET in the XCVR Guide, so too the availability of the new QSFP28 products won't be enabled for the 6400 until we get the CX 10.11 release (ETA Nov).
That Nov CX 10.11 also enables regular QSFP28 product on the 9300; we released the 9300 starting in Aug for only the interconnects listed on the Datasheet. There will be an update to include the 100G QSFP28, and 40G QSFP+ products with 10.11.
Roy, confirming your thinking: YES a 100G FR1 optic can indeed be used to create a 100G Link, and given it's a 2km optic, is significantly less expensive than a 100G LR4.Both technologies use only 2 of SMF; LR4 puts 4 wavelengths over each of the fibers, creating the 4x25G streams to get to 100G bandwidth;FR1 uses 2 wavelengths of 2x25G PAM4 so it results in 2x50G bandwidth on each fiber, and that's your 100G link.FR1 = 2 lambda LR4 (and ERL4) use 4 lambda
so you see how they are not compatible to connect to each other.The splitting (optically) of the 400G DR4/eDR4 uses 8 channels of 2x25G_PAM4(i.e. 2x50G bandwidth, 8 channels * 50 = 400G)
Note the 400G eDR4 uses a regular MPO12 connector(only 8 are used), but this time, it's SMF and each set of 2 fibers = 100G bandwidth and compatible with a 2-fiber FR1 optic up to 2km away.
