RJ-45 Shielded Coupler
The Black Box FM693 is a straight-pin RJ-45 female-to-female coupler built with a silver metal shielded housing. It joins two terminated Ethernet cables to extend a run without re-termination. The metal body provides EMI shielding for reliable data integrity in Category 6 environments. This component suits installers and network technicians who need a durable inline connection.
Sustained Signal Integrity
The shielded metal enclosure maintains consistent attenuation and crosstalk performance across the full cable run. Unlike plastic alternatives, the conductive housing grounds the shield path continuously, preventing degradation during long-term operation. RoHS and WEEE compliance confirms restricted hazardous substances for safe deployment in regulated projects. TAA compliance allows use on government procurement schedules requiring domestic-origin components.
Upgrade From Plastic Keystones
This coupler replaces unshielded plastic keystone couplers where electromagnetic interference degrades throughput. The metal construction adds mechanical strength for high-vibration or frequent-reconfiguration scenarios. The jump is worth it when shielding continuity and physical durability outweigh the minimal size increase of 0.5 by 0.3 by 1.3 inches. It does not suit installers needing a tool-free punch-down termination or a keystone footprint for wall plates.

Questions about this item
Will the shielded metal housing of the FM693 generate noticeable heat during continuous PoE use?
The passive metal coupler has no active components, so it produces no measurable heat even when Power over Ethernet runs through it all day.
What cable type and termination must already be in place for this RJ-45 coupler to work?
Two terminated Cat6 patch cords with standard RJ-45 plugs are required; the coupler simply joins them pin-to-pin.
Can the FM693 connect a legacy Cat5e patch cord to a newer Cat6 run without degrading the link?
Yes, the straight-through pinout passes all four pairs, so a Cat5e cord works but the channel remains limited to Cat5e performance.
