Re: breakout

Hi, yep, that's the right way to work cleanly, just add a «special patch panel» instead of dealing with plenty of additional wires. We use such method to do 10GE with routers modules full of QSFP+ configured as 4x10. On our side we went for a modular Huber+Suhner solution, 1 U with a maximum o

Re: breakout

Hello In my opinion the "nice" way of breaking out QSFP into 10G is something like this: https://www.fs.com/de-en/products/43552.html 40GBASE-PLR4 to 10GBASE-LR Breakout Panel 1U Rack-Mount, 24x LC Quad, 12x MTP Elite (0.35dB IL), Single Mode You connect your QSFP module using a MTP cable to t

Re: breakout

I doubt it applies to Randy's 48 port switch (and maybe in general), but for posterity: be advised that the QSFP28 to SFP+ adapter is physically taller than a standard QSFP28 optic, outside of the device. Inside is still to spec of course. Sort of like how RJ45 SFPs are slightly taller than fiber

Re: breakout

Old module says "10G_BASE_SX" so that is multimode fiber, which complicates things a bit. You can see about getting a single-mode handoff instead, or you may need the QSFP-SFP+ adapter (or intermediary switch). thanks, -Randy - On Jan 8, 2020, at 2:26 PM, Ben Cannon b...@6by7.net wrote:

Re: breakout

This is another good way to go, make sure you have a single mode handoff from the IX (you should, but double check this, orange fiber and yellow fiber are very different physically in size and generally not compatible. -Ben Cannon CEO 6x7 Networks & 6x7 Telecom, LLC b...@6by7.net

Re: breakout

I think you're looking for an MTP breakout cable, rather than a QSFP28 breakout. The MTP breakout requires separate optics, whereas the active breakout can plug directly into a device's SFP+ ports. Something like... https://www.fs.com/products/24422.html And https://www.fs.com/products/41426.htm

RE: breakout

You'd need something like this, which you can jumper over to the 10G port. https://www.fs.com/products/37016.html Cable to break it out. https://www.fs.com/products/68048.html Luke Ns -Original Message- From: NANOG On Behalf Of Randy Bush Sent: Wednesday, January 08, 2020

Re: breakout

AOC stands for Active Optical Cable, which means it’s really 4 SFP+ and a qsfp plus intermediate fiber all permanently attached. 1M is the length, 1 meter. This is distinct from DAC (Direct Attach Cable) which is all copper (you don’t want these, fiber for one thing isolates ground/emi) This
