Corning CheckPoint™ PROThe Checkpoint™ PRO is a lightweight, handheld, easy-to-use tool to safely and effectively identify the transmission direction, fiber path and relative core power on live optical fibers.

The Checkpoint PRO uses the super-low insertion loss local detection method of macro-bending. This allows for detection of the optical signals during installation and maintenance without disconnecting the fiber or interrupting the traffic signal. The Checkpoint PRO eliminates the need to open the optical fiber at the splice point reducing the probability of interrupting service to your customer.

• Fixed head design
• Live traffic testing
• Tone signal testing
• Detects 2 kHz, 1 kHz and 270 Hz
