• NTDK79 3 km Fiber Expansion Daughterboard (Single Mode glass
fiber-optic cable)
• NTDK80 3 km Fiber Receiver card (Single Mode glass fiber-optic cable)
Note: Fiber-optic cable is the only type of interconnection cable
supported on a fully expanded Chassis system.
The following safety precautions must be followed when handling fiber
equipment:
• All persons handling Fiber Expansion Daughterboards and Receiver
cards must be Electrostatic Discharge (ESD) protected. A wrist strap
provided with the cabinet also must be worn when handling fiber-optic
cables to prevent damage caused by static electricity.
• Always ensure the fiber-optic cable is routed out of the way of any traffic
through the premises.
• Never staple or bend the fiber-optic cable at an extreme angle. Do not
exceed the minimum bend radius of 1.5 in (35 mm) (90° soft bend).
Note: A conduit is not required for routing fiber-optic cable between
cabinets or chassis. However, if you require a conduit for identification
or other reasons, use a conduit measuring a minimum of 1 in. (25 mm) in
diameter.
