AI Thread Summary
Designing a dual port 1000Base-T Gigabit Ethernet circuit card poses space challenges, prompting a shift to fiber-optic systems for smaller connectors. Transitioning from RJ45 MagJack to a fiber optic module requires ensuring compatibility with 1000BASE-X, potentially necessitating changes to RGMII and MAC interfaces. Board layouts for fiber differ from copper, primarily in connector size and signal integrity considerations. SFP transceivers are suggested as a compact solution, capable of replacing RJ45, magnetics, and PHY components. Resources and documentation on these design transitions are sought for further guidance.

I'm currently designing a dual port 1000Base-T Gigabit Ethernet circuit card. My problem is that I do not have much space to work with on my board and the dual port RJ45 Magjack is taking up a ton of space. To save space I've been looking to switch to a fiber-optic system with much smaller connectors.

Anyone have experience laying out a fiber design? Could I essentially just switch out my RJ45 MagJack with a fiber optic module and switch my PHY to one that supports 1000BASE-X? In other words would I have to change my current RGMII and MAC interfaces to support fiber?

How is a board layout with fiber different than with copper?

Any documents on these topics would be helpful, I'm having difficult finding them.

Thank you,
-Kevin

While looking for space saving solutions for my gigabit ethernet board I found SFP transceivers. Does anyone have any experience with these? Can one 1000BASE-T SFP transceiver replace the RJ45, Magnetics, and PHY on my board?

Thanks,

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
