QSFPTek SFP and SFP+ Transceivers - Fiber and Copper

A quick overview of various types of QSFPTek SFP+ and SFP transceivers. We discuss the different types of fiber versions, such as Long Range and Short Range models, as well as the copper RJ45 type that allow you to use a standard ethernet cable.

Thank you so much for acually showing the ends of the transceivers and how they work in relation to a switch, have networking+ next tuesday and this has been stressing me out

missed this video. thx for sharing

this covered exactly what i needed to know. this video is certainly worth 1k+ likes considering the useful info for beginners getting into sfp+ the first time.

None of the other videos by others i've covered it this well.

Thank you, I'm planning my move from 1G copper to 1G fibre and then onto 10G, this video was helpful.

Hei Mike, i managed to upgrade to sfp+ 10g. Your video helped me a lot. i particularly watched how you inserted the fiber optic multi mode om3 cable into the transceiver. so that helped.

So with the Ethernet cable plugged into the transceiver as at 3:17, can that cable then simply go to an Ethernet switch?

DAC > fiber > RJ-45 transceiver for "local" connections, i.e., where you can find a DAC cable of the proper length. DAC is cheaper, lower power and more compatible than any transceivers.

Do the fiber transceivers run cooler than the Rj45 counter parts?

Good afternoon You are doing a great job! thereby making life easier for the engineer! Thank you!
I have an unusual case, I want to make a small board that connects 2 DAC passive cables at 100GB speed.
But I can't get the host system to work through my board and 2 DAC passive cables. The DAC cable is 50cm long. The lines on the board are 15 cm long; there is an overlap of RX <-> TX signals on the board.
Tell me where to look? Who did something like this?

[Notmy]

can give you an explanation about db db/m for fiber

Are these compatible with Cisco Catalyst switches?
