Routing

Hi,

I know that this can support 1Gb SFPs, but has anyone managed to test whether you can use a copper SFP and connect a device at 100Mb?

Will the ACS5048 support 100Mb F/D speeds using a 1Gb copper SFP?

Thanks in advance,

Matt

Hi, mskipsey!

I don't personally have the ACX 5048 but reviewing the ACX 5000 series documentation it does not appear so. Here are the relevant portions of the document.

All 48 of these ports can be used for SFP+ transceivers or SFP+ direct attach copper (DAC) cables. You can use 1-Gigabit Ethernet SFP, 10-Gigabit Ethernet SFP+ transceivers and SFP+ direct attach copper cables in any access port.

And on the Interface Specifications for SFP, SFP+, and QSFP+ Transceivers for an ACX5000 Router page you can see for the Gigabit transceivers only the 1000Mbps rate is supported.

I hope this helps.

I can confirm that 100 Mbps optics are not supported on ACX5048 - with Junos 17.3R1 the smaller platform now supports for 100 Mbps but a bit strange that it wasn't a focus for ACX5000.

Interesting find, as that does appear to confirm that the other ACX platforms now do support 100Mb optics, but not the 5000 series.

Bummer.

Some of our services are handed off to us on 100Mb copper.

I guess we'll have to put an intermediary EX switch between the ACX5048 and the network provider's NTE.
