10Gtek 25G Sfp28 Sfp+ Dac Cable - 25Gbase-Cr To Passive Direct Attach Copper Twinax For Cisco Sfp-H25Gb-Cu0.25M, 0.25-Meter(0.8Ft)

Having built out over well over 100 data rooms/closests/cabinets/data centers I can say when you purchase a Gtek adapter you just know it is going to work. I have installed these the last few years and have never had an incompatibility issue (make sure you get the one unlocked to a brand if needed or open compatible if you are ok with warnings and bypass them). The quality is very high with each being QCd before placing in to bags. The colors are vibrant and hard to miss with the cord lengths available to cover most situations or overkill for others. (I mean who needs a 3ft cable when a 2ft is needed. That’s what cable management is all about). Accidentally ordered the wrong interface and they returned items graciously and helped point to the correct cables. I just can’t say enough good things about this company, their products and their professionalism. If you aren’t buying cables from them then why not?

This is the first DAC cable I've purchased. This product works fine if you plug the transceiver in the correct orientation. The communication speed definitely exceeded 10G, but did not exceed 20G.

Confirmed Compatible with Dell/EMC Broadcom NetXtreme E-Series Quad-Port 25Gb OCP 3.0 And a DAS-SAN connection to Synology DS-series with Dual SFP28 on other side.

I set these up on my server network card from my MikroTik router. Success!!!

These were 1/3 the price of the nearest competition, and a simple replacement and no other steps took me from 10 GB To 25 GB ! Bought 10, zero issues!
