3-80Hardware feature descriptions

OC-3x4 optical interface circuit pack (NTN441AA, AC)

The OC-3x4 optical interface circuit pack provides the same functionality as the OC-3 optical interface circuit pack, but has four optical lines. The OC-3x4 optical interface circuit pack can provide add/drop capability for four OC-3 tributary interfaces.

Note 1: The DS1 service module (DSM) connects to the OPTera Metro 3500 network element through the ports on a host OC-3 or OC-3x4 circuit pack.

Note 2: The NTN441AA version of the OC-3x4 circuit pack is shipped from the factory with eight SC connectors located on a sliding panel and accessed from the front of the circuit pack.

Note 3: The NTN441AC version of the OC-3x4 circuit pack is shipped from the factory with four duplex LC connectors located on the front of the circuit pack.

The OC-3x4 optical interface circuit pack comes equipped with SC (NTN441AA) or LC (NTN441AC) type connectors that are located on a sliding panel and accessed from the front of the circuit pack. Pull the sliding panel out from the circuit pack just enough to complete the work required. The connectors are on the panel behind the small clear plastic doors found on each side of the panel. The clear plastic doors are labeled to ensure proper connection of the fibers. After you connect the fiber, gently push the sliding panel back into the circuit pack.

Multimode Interworking

The NTN441AC version of the OC-3x4 circuit pack supports multimode interworking for short distances (intra-office) if the following condition are met:

•The multimode fiber (MMF) complies with the characteristics as described in ANSI T1.416.01-1999:

Parameters	Value
Core diameter	62.5 ∝m
Cladding diameter	125 ∝m
Attenuation @ 1300 nm	1.0 dB/km (max)
Modal bandwidth @ 1300 nm	500Mhz-km (min)
Dispersion slope	0.093ps/nm2-km
Dispersion minimum	1365 nm (max)
