Danger —  Fiber cables transmit invisible laser light. To avoid eye 
damage or blindness, never look directly into fibers, connectors, or 
adapters.
Warning —  Be careful to maintain a bend radius of no less than 1.5 in. 
(3.8 cm) when connecting the fiber optic cable. Too small of a bend radius 
in the cable can result in damage to the optic fiber.
Note —  Fiber cable preparation varies depending on the type and size 
of the inside or outside plant fiber cable being spliced to the SC/APC or 
SC/UPC fiber optic pigtail cable.
Note —  Observe the following:
• Units must be powered by a Listed or CE approved and marked 
limited power source power supply with a minimum output rate of 
12 VDC, 2.5  A.
Note —  A new SLID or the old SLID may be used with the replacement 
ONT. If a new SLID is used, the new SLID must also be programmed at 
the P-OLT using TL1 or a network manager. If the old SLID is used, no 
changes need to be made at the P-OLT; see the operations and 
maintenance documentation for the OLT for more details.
