The OPTICAL CABLE CORP. UMJA609L is a UMJ-series Cat6 keystone jack with a yellow bezel, designed for structured cabling installations in commercial and residential network environments. The yellow bezel provides a visual identification aid for port management in patch panels and wall plates. This jack is sold as a single unit and is installed by low-voltage cabling technicians and network infrastructure professionals as part of a permanent link termination point.
The UMJA609L is suited for horizontal cabling runs terminating at work area outlets, patch panels, or surface-mount boxes in office, education, healthcare, and light industrial settings. Its Cat6 rating supports high-speed Ethernet data transmission at the frequencies required by current structured cabling standards. The yellow bezel is commonly used in color-coded cabling schemes for port identification and zone separation.
Designed as an OEM-style replacement or new-installation keystone jack for Cat6 structured cabling systems using standard keystone-format wall plates, patch panels, and surface-mount enclosures.
Installation should be performed by a qualified low-voltage cabling technician in accordance with ANSI/TIA-568 structured cabling standards. De-energize any adjacent powered equipment before terminating conductors at the jack. Use a 110-style punch-down tool appropriate for the jack termination type. Verify cable pair assignments against the wiring standard specified for the installation before punching down.
