@chuc your OM4 fibre is a multimode, and will happily do 10Gbps at that length. As it is 175m you will find it hard to get 40Gbps to work, generally with only one pair of fibres (using LC connectors) the maximum distance is 150m. You could go further if you had multiple pairs in a MPO connector. The Meraki SFP data sheet, which show lengths and fibre types, is available here, https://meraki.cisco.com/lib/pdf/meraki_datasheet_sfp.pdf. Since all your links are OM4 with LC connectors I’d use MA-SFP-10GB-SR everywhere to use 10Gbps speeds. Don’t worry about your English, it is great, far better than my French.
