Subracks are the basic working units of the OptiX OSN 8800 T16. Each subrack has independent power supply.
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.
Functions and Features
Table 1 describes the functions of a fan tray assembly.
| Function | Description |
|---|---|
| Basic function | Dissipates the heat generated by a network element (NE), so that the NE can operate normally within the designated temperature range. |
| Commissioning control |
|
| Partitioned heat dissipation |
Each subrack is divided into three partitions to help provide efficient heat dissipation. The fan speed in each partition is independently regulated. |
| Hot swapping | Provides the hot swapping function for the fan tray assembly. |
| Alarming | Reports alarms of the fans, and reports the in-service information. |
| Status checking | Checks and reports on the fan status. |
The cross-connect capacity of a slot in an OptiX OSN 8800 T64 subrack vary according to the type of cross-connect board installed in the slot.
OptiX OSN 8800 T64 subracks can cross-connect ODU0, ODU1, ODU2, ODU2e, ODU3, ODU4, ODUflex, VC-4, VC-3, and VC-12 granularities at the same time. Slots IU1-IU8, IU11-IU42, and IU45-IU68 provide the same cross-connect capacity. As shown in Table 1.

a: In OptiX OSN 8800 T64 enhanced 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. b: k=0, 1, 2, 2e, 3, 4 or flex. Only the USXH+UXCT supports ODU4 granularities. c: Enhanced OptiX OSN 8800 T64 subracks must be configured with both the USXH and UXCT boards, the SXH and XCT boards or the SXM and XCT boards to cross-connect ODUk granularities. d: General OptiX OSN 8800 T64 subracks must be configured with both the SXH and XCT boards or the SXM and XCT boards to cross-connect ODUk granularities. e: All service slots share a bandwidth of 80 Gbit/s. Two functional versions are available for SXH, SXM, and XCT boards: TNK2 and TNK4. The boards can be used in OptiX OSN 8800 T64 enhanced subrack only when they are of the TNK4 version. |
