According to your product model information, it is recommended that you use #11555 for the single-mode module (https://www.fs.com/products/11555.html). The multi-mode module uses #11552 (https://www.fs.com/products/11552.html?attribute=77&id=219724). This will ensure that the product and your device can be used normally. By D***g on 04/06/2021

Hello, thanks for your question. Yes, when used with the different brands of equipment, the transceivers need to be written with corresponding codes, for Microtik switches CRS305 & CSS610, and modules write neutral codes as #74668. Used for Mellanox NICs, the optic #65334 will be suitable. By E***o on 01/27/2021

The 10GBASE-LRM Module supports link lengths of 220m on standard Fiber Distributed Data Interface (FDDI) grade Multimode Fiber (MMF). To make sure that specifications are met over FDDI-grade, OM1 and OM2 fibers, the transmitter should be coupled through a mode conditioning patch cord. No mode conditioning patch cord is required for applications over OM3 or OM4. By B***g on 11/13/2020
