Hi All, We know that Cisco usualy OEM SFPs from Finisar and other brands. But c an anybody tell which one of those SFPs is the correct replacement for Cisco GLC-T (or if all of them work): Finisar's FCLF-8520-3 or FCLF-8521-3 It seems like the difference between Finisar's 8520-3 & 8521-3 models are in RX_LOS pin operations: http://www.finisar.com/sites/default/files/pdf/ZEBIYYxugGDBFCLF-8520-3_FCLF-8521-3_Spec_RevB .pdf but it is unclear which one of them is the closest to GLC-T. It looks like the same is true for Avago who has: Avago ABCU-5700RZ or ABCU-5710RZ If you have an experience with any other 1000BASE-T SFPs that will work with Cisco routers please let us know. Thanks.
