Single-port Fiber Expansion Daughterboards
Each Single-port Fiber Expansion Daughterboard can interface with one
expansion cabinet/chassis. Each daughterboard port provides ten additional
card slots. The daughterboard port in connector one on the SSC card provides
card slots 11 to 20. The daughterboard port in connector two on the SSC card
provides slots 21 to 30. You must match each type of daughterboard with the
appropriate Fiber Receiver card. For information on Fiber Receiver cards,
refer to "Fiber Receiver cards" on page 28. The following are three types of
Single-port Fiber Expansion Daughterboards:
• NTDK22 single-port Fiber Expansion Daughterboard: used with the
A0632902 fiber-optic cable (multi-mode) and the NTDK23 Fiber
Receiver card
• NTDK24 single-port Fiber Expansion Daughterboard: used with
glass fiber-optic cable (multi-mode) up to 3 km (1.8 mi) in length and the
NTDK25 Fiber Receiver card
• NTDK79 single-port Fiber Expansion Daughterboard: has the same
capabilities as the NTDK24 except that it interfaces with single-mode
fiber-optic cable. It is used with the NTDK80 Fiber Receiver card.
Dual-port Fiber Expansion Daughterboards
Each dual-port Fiber Expansion Daughterboards can interface with up to two
expansion cabinets/chassis. Each daughterboard port provides ten additional
card slots. The daughterboard ports in connector one on the SSC card
provides card slots 11 to 20, port two provides card slots 31 to 40. The
daughterboard ports in connector two on the SSC card provides slots 21 to 30,
port 2 provides card slots 41 to 50. You must match each type of
daughterboard with the appropriate Fiber Receiver card. Refer to "Fiber
Receiver cards" on page 28 for information about Fiber Receiver cards. The
following are two types of Dual-port Fiber Expansion Daughterboards:
• NTDK84 dual-port Fiber Expansion Daughterboard: used with the
A0632902 fiber-optic multi-mode cable and the NTDK23 Fiber
Receiver card
• NTDK85 dual-port Fiber Expansion Daughterboard: used with glass
fiber-optic cable (multi-mode) up to 3 km (1.8 mi) in length and the
NTDK25 Fiber Receiver card
Note: Glass fiber-optic cable (multi-mode or single-mode) must be
