Black Box ME662A-SSC Async RS232 Extender, Fiber, DB9 Female, 30 km

Move async RS232 traffic beyond the rack without exposing the link to electrical noise, ground potential differences, or distance limits that break copper serial runs. Black Box ME662A-SSC extends serial communication over single-mode fiber and supports DB9 female connectivity for equipment that still depends on RS232 control, monitoring, and console access. This model is built for environments where serial links must stay stable across buildings, plant floors, utility spaces, or remote equipment rooms. By converting the connection to fiber, it helps preserve signal integrity over long spans while reducing susceptibility to interference that can disrupt mission-critical serial traffic. The 30 km reach gives infrastructure teams room to place devices where they belong instead of where cable length allows. For organizations maintaining legacy controllers, industrial systems, or network gear with serial management ports, this extender offers a practical way to keep those assets in service. It is a focused solution for teams that need dependable RS232 extension over fiber, not a generic converter. That specialization is what makes it worth specifying in environments where downtime, re-cabling, or device replacement carries real cost.
