Cable specifications and interfaces
Plastic Fiber Optic cable (Multi-mode)
The A0632902 Fiber Optic cable is a 10 m (33 ft) plastic fiber cable which is
used when the expansion cabinet is located 10 m (33 ft) or less from the main
cabinet. This cable comes equipped with a connector on each end which
connect to either the NTDK22 or NTDK84 Daughterboard in the main
cabinet and to the NTDK23 Fiber Receiver card in the expansion cabinet.
Excess cable is stored by means of cable management devices in the cabinets.
This cable, which is the only cable that can be used for this purpose, is not
intended to be cut or altered in the field.
Glass Fiber Optic cable
Glass fiber optic cable (Multimode or Single Mode, depending on interface
cards) is required when the cable length between the main cabinet and an
expansion cabinet is up to 3 km (1.8 mi).
Note: The distance between the main cabinet and expansion cabinet is
determined by the length of the fiber optic cable — not by linear distance.
This glass fiber cable, which is supplied by a local telephone company or
other facilities provider, must be dedicated to the Option 11C (it cannot be
shared with other services).
A connector is required on each end of the cable to connect to the
NTDK24 (Multimode), NTDK85 (Multimode), or NTDK79 (Single Mode)
Daughterboard in the main cabinet and to the NTDK25 (Multimode) or
NTDK80 (Single Mode) Receiver card in the expansion cabinet. Excess cable
is stored by means of cable management devices in the cabinets.
Note: The Option 11 C fiber optic link for distances up to 3 km (1.8 mi)
uses the industry standard 62.5/125 µm glass multimode duplex cable
with ST-type connectors.
The type of cable used depends on the type of installation and any local
building codes.
