Fiber Receiver cards.
Fiber Receiver cards in fiber expansion cabinets, allow for fiber connectivity
between the Main Option 11C and 11C Mini and up to four fiber expansion
cabinets/chassis.
There are three versions of the Fiber Receiver card, each of which has a
corresponding fiber daughterboard:
1 The NTDK23 Fiber Receiver card is used when the expansion cabinet is
within 10 m (33 ft.) of the main cabinet. It connects to one A0618443
Fiber Optic plastic cable.
2 The NTDK25 Fiber Receiver card is used when the expansion cabinet is
between 10 m (33 ft.) and 3 km (1.8 mi.) of the main cabinet. It connects
to one glass multi-mode fiber optic cable which is dedicated to the
Option 11C system.
3 The NTDK80 Fiber Receiver card provides the same functions as the
NTDK25 except that it connects to Single Mode fiber optic cable and is
used for connections over 3 km.
