A: Generally speaking, the answer is "no". For example, 1000BASE-LX single mode SFP can work on multimode fiber cable by using mode. For multimode check the light, make sure Rx and Tx are connected properly. Multi-mode optical cables has wide fiber core 50 µm for OM4 (your case), In contract – single mode optical cable core is narrow – 9 µm. This leads to unreliable network performance. Here's why: Light source & beam profile: SM lasers are narrow and Coherent; they couple efficiently into a 9 µm core. MM VCSELs/LEDs produce a broader beam.
