We decided to give MGBIC-08 1000BASE-ELX (70KM) 1 LC PORT but, its wave length is different from Cisco.<BR /> <BR /> GLC-EX-SMD wave lenght 1310nm, 40km<BR /> MGBIC-08 wave lenght 1550nm, 80km<BR /> <BR /> So, I will be glad if you tell me the equivalent Extreme SFP model of Cisco.<BR /> <BR /> Regards,<BR /> <BR /> Yasar<BR /> Wed, 22 Mar 2017 18:22:00 GMT https://community.extremenetworks.com/t5/network-architecture-design/extreme-sfp-compatibility-with-cisco/m-p/14805#M2209 Yasar_Karacan 2017-03-22T18:22:00Z https://community.extremenetworks.com/t5/network-architecture-design/extreme-sfp-compatibility-with-cisco/m-p/14806#M2210 Hi Yasar, what switch model(s) will your customer be using the EX SFP with?<BR /> Thu, 23 Mar 2017 01:24:00 GMT https://community.extremenetworks.com/t5/network-architecture-design/extreme-sfp-compatibility-with-cisco/m-p/14806#M2210 Drew_C 2017-03-23T01:24:00Z https://community.extremenetworks.com/t5/network-architecture-design/extreme-sfp-compatibility-with-cisco/m-p/14807#M2211 Hi Drew,<BR /> They will use EX SFP's on Cisco switch, I do not know the exact model, and they will use the Extreme SFP on N-Series chassis as backbone.
