- Network technicians linking buildings, floors, or wiring closets over single-mode fiber, when a 1GbE link of up to 10 km fits the network plan.
- Organizations extending an existing multimode-fiber network between nearby equipment rooms, for 1GbE links within the applicable reach of their fiber and installation.
- Network administrators who use DDM-capable equipment and want transceiver status information available to their network monitoring tools.
- Teams using an MSA-compliant switch from another listed vendor, provided they have confirmed that the specific switch accepts this uncoded SFP.
