Option 11C fiber optic cable interfaces

Fiber Expansion daughterboards

Cable specifications and interfaces
Note 1: The distance between cabinets is determined by the length of the
fiber optic cable.
Note 2: The fiber optic cable interface equipment used with Option 11E
is unique to that system, and cannot be used with Option 11C. Similarly,
the fiber optic cable interface used with Option 11C cannot be used with
Option 11E.
Note 3: With 100baseF Expansion Daughterboards and third party
converters, the distance can be extended to more than 20km.
Fiber optic interface hardware used with Option 11C consists of Fiber
Expansion daughterboards mounted on the NTDK20 small system controller
card in the main cabinet and Fiber Receiver cards mounted in the expansion
cabinets.
Note 1: Any reference to Option 11C cabinets in this section equally
applies to Option 11C Mini chassis if you are using them in your IP
Expansion system.
Note 2: The MFI and EFI units used with Option 11E to interface with
fiber optic cable cannot be used with Option 11C.
Fiber Expansion daughterboards mounted on the NTDK20 SSC card allow
the connection of fiber optic cables from the main cabinet to expansion
cabinets in multi cabinet Option 11C systems. Each daughterboard also
provides an additional 16-channel conference loop and one SDI port at the
expansion cabinet. There are five types:
• The NTDK22 Fiber Expansion Daughterboard
• The NTDK24 Fiber Expansion Daughterboard
• The NTDK79 Fiber Expansion Daughterboard
• The NTDK84 Fiber Expansion Daughterboard
• The NTDK85 Fiber Expansion Daughterboard
