Whilst Metrodata's fibre product ranges use industry standard user exchangeable SFPs, it is recommended that these are purchased from Metrodata to guarantee their specification and compatibility with each other. For all fibre transceivers including vendor compatible SFP, SFP+, XFP, X2 and XENPAK transceivers, with long distance, CWDM or DWDM specifications then please contact our sales team with your requirements.
