Nortel Meridian 1 Option 11C Upgrade Manual page 79

Upgrade a two-cabinet system with metal cable to Option 11C
23 Locate the fiber receiver card.
— Do you want to connect the expansion cabinet with A0632902
(was A0618443) plastic fiber-optic cable within 10 m (33 ft) of the
main cabinet? If so, use an NTDK23 Fiber Receiver card.
— Do you want to connect the expansion cabinet with glass
fiber-optic cable up to 3 km (1.8 mi) from the main cabinet? If so,
use an NTDK25 (multimode) or NTDK89 (single mode) Fiber
Receiver card.
24 Connect the fiber-optic cable to the fiber receiver card as shown
in Figure 32 on page 80.
Use of the fiber-optic interface product in the Option 11C is
considered safe. However, as a precaution, do not look directly at the
optical port or the end of fiber-optic cable. The cable or port can cause
eye exposure beyond the limits of Maximum Permissible Exposure
recommended in some areas. For example, this condition can occur
during cable testing or under light magnification. Do not remove
protective caps or plugs until you are ready to connect the cable.
Use one of the following methods:
— If using the A0632902 (was A0618443) cable:
a Remove the two protective plugs from the fiber receiver card.
b Connect the cable to the fiber receiver card. Make sure the
V-shaped groove on the cable connector faces in and the
connector seats tightly. See Figure 33 on page 81. The
marking (if there is one) on the connector is not visible when
connected correctly.
— If using glass fiber-optic cable:
a Remove the protective plug from the fiber receiver card.
Remove the protective cap from the corresponding plug (Tx or
Rx) on the glass fiber-optic cable.
b Insert the plug in its identified connector on the fiber receiver
card.
