a: In enhanced OptiX OSN 8800 T32 subrack, the maximum OTN service cross-connect
capacity of a single slot can be smoothly increased from 40 Gbit/s to 100 Gbit/s by
replacing the cross-connect board. In general OptiX OSN 8800 T32 subrack, the maximum
OTN service cross-connect capacity of a single slot can be smoothly increased from 40
Gbit/s to 80 Gbit/s by replacing the cross-connect board.
b: k = 0, 1, 2, 2e, 3, 4, or flex. Only the UXCH or UXCM supports ODU4 granularities.
c: Theoretically, the enhanced subrack supports grooming of a maximum of 1.6 Tbit/s
packet services. In practice, however, the packet service grooming capability of the
enhanced subrack is determined by packet boards. The current version provides a packet
service grooming capability up to 1.28 Tbit/s.
d: All service slots share a bandwidth of 80 Gbit/s.
4.3.5 Fan and Heat Dissipation
Each OptiX OSN 8800 T32 subrack has two fan tray assemblies, each of which includes three
independent fans. In each subrack, the lower fan tray assembly has an air filter, but the upper
fan tray assembly does not have an air filter. The air filter can be drawn out, cleaned and
replaced.
Version Description
Only one functional version of the fan tray assembly is available, that is, TN51.
