Re: [USRP-users] SFP Transceivers for N310 1/10Gbps Fiber Ethernet
I tried that FS SFP+ transceiver again with HG image and it works when the other side is connected to a correct NIC. It seems to be another confirmation of FS SFP-10GLR-31 module. Thank you Rob and Ashish.

Re: [USRP-users] SFP Transceivers for N310 1/10Gbps Fiber Ethernet
I have used this SFP+ transceiver for both the X310 and N310, both with XG images. I do not remember if I tried the X310 with the HG image, but I think so. I am using 10gbe with single mode fiber - approximately 100m.

Re: [USRP-users] SFP Transceivers for N310 1/10Gbps Fiber Ethernet
Hi Ashish, 10GBASE-LR is preferred in my project. 1GbE copper is a workaround if 10GbE fiber is not available at certain site. The only thing is that I need long distance fiber (2km-10km). So I could not use the first one you recommended. When using HG image, do I need to disconnect SFP0 so that SFP1 could work? Can I set both SFP0 and SFP1 in the same subnet? If I got the right SFP+ transceiver plugged in SFP1, should the LEDs be on? In my case, only LEDs of SFP0 on when I plugged in converter/transceiver on both ports. Thanks.

Re: [USRP-users] SFP Transceivers for N310 1/10Gbps Fiber Ethernet
Hi Rob, Thanks, I just tested FS SFP-10GLR-31 on HG image (I connected to SFP1) but unfortunately it does not work. Maybe I should do some more test. That module actually work for my Dell switch. Which FPGA image did you use? Are you connecting fiber to SFP0 or SFP1 or both? Is that 10Gb Ethernet connection? Thanks.

Re: [USRP-users] SFP Transceivers for N310 1/10Gbps Fiber Ethernet
Hi Zhongyuan, >> Does 10Gbps SFP+ transceiver backward compatible with 1Gbps socket? No it's not. Depending on what N310 FPGA image you build/use, the port speeds are locked down. The HG image is 1G on SFP0 and 10G on SFP1 whereas the XG image has 10G on both SFP ports. The transceiver might support both speeds but the USRP won't. >> Could you recommend any SFP transceivers that work on your case? both >> 1Gbps and 10Gbps. What speed do you need for your application? What is the speed of the switch that you are working with? The solutions for 1Gbps and 10Gbps are vastly different. Generally speaking fiber-optics that support 10GBASE-SR, -LR and -ER should work with the N310 when the SFP port is in 10G mode and optics that support 1000BASE-LX, -SX and -CX should work in 1G mode. For Ethernet, I should mention that certain switch and NIC vendors explicitly disallow certain non-approved optical modules, so on the switch side I would double check with the vendor that the transceiver works with your switch. On the USRP side, we accept all optics. I haven't used the specific Finisar module (FTLX1475D3BCV) but in general we have seen good results with Finisar, Amphenol FCI and Elpeus transceivers. We do most of our testing with full cable assemblies, although those might be a bit harder to find for the lengths that you are looking for. As a data point here are the ones that are known to work: https://www.mouser.com/ProductDetail/Finisar/FCBG110SD1C03?qs=sGAEpiMZZMsi6nco80NB4Pt5EfrefmupuvEijLXVquZ4ABfDcakyUQ%3d%3d https://www.serversupply.com/NETWORKING/TRANSCEIVER/10%20GIGABIT/INTEL/FTLX8571D3BCVIT1.htm Thanks, Ashish On Sat, Jul 21, 2018 at 2:17 PM, Zhongyuan Zhao via USRP-users wrote: > Has anyone tried 10G/1G Dual Rate (10GBASE-LR/LW and 1000BASE-LX) 10km > 1310nm Single Mode Datacom SFP+ Optical Transceiver? > https://www.finisar.com/optical-transceivers/ftlx1475d3bcv > > Thanks. > > > > Zhongyuan Zhao > > PhD Candidate, > Department of Computer Science & Engineering, > University of Nebraska-Lincoln > Suite 117, Schorr Center, > Lincoln, Nebraska 68588-0115 > > On Fri, Jul 20, 2018 at 2:06 PM, Zhongyuan Zhao wrote: >> >> Hi, >> >> I am working on a project where several N310s are connected to a >> fiber-Ethernet switch.

Re: [USRP-users] SFP Transceivers for N310 1/10Gbps Fiber Ethernet
Has anyone tried 10G/1G Dual Rate (10GBASE-LR/LW and 1000BASE-LX) 10km 1310nm Single Mode Datacom SFP+ Optical Transceiver? https://www.finisar.com/optical-transceivers/ftlx1475d3bcv Thanks.
