The assembly provides terminations for fiber optic cable armors under the control of 2000 or 4200 Cable Management Systems. These terminations include an LTU which terminates locate tones above 250 Hz and a 2230 STU which terminates the cable monitoring functions. Both the LTU and STU contain a high voltage surge arrestor that provides low impedance ground path for high voltage transients. Induced Voltage Filters are also included to provide a low impedance path to ground for induced 60 Hz AC current.

Features

• Terminates two cable armors
• Pre-wired to simplify office installation
• Terminations installed for both cable location and cable monitoring
• Surge arrestors located in terminations provide surge current protection and transient suppression
• Induced Voltage Filters providing low impedance path to ground for induced 60 Hz current
• Fiberglass polyester enclosure which meets NEMA and CSA standards for electrical enclosures
