Fiber Type: Single-mode (implied by SR, though SR usually refers to short-reach and is often used for multimode, this product description is a bit ambiguous and Dell's specific part number dictates the exact specs)
Connector Type: LC (standard for SFP SR transceivers)
Wavelength: 850nm (typical for SR over multimode) or 1310nm (typical for SR over single mode, but less common for 'SR' designation) - *Exact wavelength would need confirmation based on Dell's specific implementation for this part number.*
