19.1.2 Fiber Optic Cables
Twin single-mode fiber optic cables with Dual-LC plug must be connected to the PSTN
transceivers 1A and 1B on the 6310/RTM module in the rear of the chassis. For PSTN
interface redundancy, it is recommended to connect two STM-1/OC-3 links to each
6310/RTM module.
Care in Handling Fiber Optic Cabling
When handling the fiber optic cables, be sure to note the following:
• Excessive bending of the Fiber Optic Cable can cause distortion and signal
losses
• Ensure you abide by the minimum bending radius recommended by the Fiber
Optic Cable supplier
• Maximum Fiber Optic Cable length for multi-mode fiber is 2 km
• Maximum Fiber Optic Cable length for single-mode fiber is 22 km
