Is there any cheap way to convert from CX4 to RJ45?

sh flag

I have an HP ProCurve 2900 with 2 x CX4 10Gb ports in the back. And I want to somehow link it with my internet provider 10Gb hub, which only has a 10Gb RJ45 connector.

So far I was only able to find on Google, CX4 to CX4 cables, or 10Gb CX4 network cards, but I am not able to find any cheap converters from CX4 to RJ45.

Any idea where can I find such an adapter, if it exists ?

Thanks

You might need to brush up your Google skillz, see: https://dcscom.net/data-communications-en/media-converters-en/copper-to-fiber-media-converters-en/10g-media-converters/s-10gt-xfph-media-converter/

At that amount of money I can by a handful of 10Gb new switches. I'm looking for something with a decent price. up to 50$ if possible. (I've only payed 20$ for the ProCurve switch)

@Draco There used to be a D-Link converter for $500 but $50 is a dream (unless you find it used). -CX4 and -T use vastly different encoding and there's only a teeny tiny market, so the price badge is justified.

CX4 is a dead connector and fell into disuse a long time ago.

The ProCurve 2900 went end-of-life ~13 years go.

Your internet provider is giving you a 10GbE handoff, but you can use a 1GbE port on your existing switch.

If you require 10GbE connectivity, you should plan for a newer switch.

Yes I know it is an old switch and an old connect. My internet provider service offers speeds up to 3Gb. If I connect it over 1Gb port i loose 2/3 of my bandwidth.

@Draco Do you need the bandwidth? Then it's a new switch.

For whoever will be interested, I've managed to find a module for my swich which exposed 2 x SFP+ modules: HP ProCurve 2- Port 10-GbE SFP+ al Module (J9008A) . https://support.hpe.com/hpesc/public/docDisplay?docId=emr_na-c02620659 and managed to find a second had one for about 70$

@Yonoss That module is for the 29**10**al switch series. The 29**00** in your question only supports CX4 and X2.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
