Functions and features of the OptiX OSN 9500

1. As an optical-electrical-optical (OEO, with an "electrical core") bandwidth switching equipment, the OptiX OSN 9500 can cross-connect the services of VC-4, VC-3, and VC-12 granularities.
2. The OSN 9500 provides a large cross-connect capacity for multi-granularity services. The cross-connect boards of the OSN 9500 provide 2560 x 2560 or 4608 x 4608 VC-4 higher-order non-blocking cross-connect capability, and 8064 x 8064 VC-12 lower-order cross-connect capability, support flexible grooming of VC-12, VC-3, and hybrid services, and offer the service grooming function.
3. The OSN 9500 has high integration. It supports the access of SDH signals at various rates (such as STM-64, STM-16, STM-4, and STM-1) and the access of GE signals. The OSN 9500 also supports VC-4-64c, VC-4-16c, and VC-4-4c concatenated services. The OSN 9500 is highly integrated. A single subrack supports a maximum of 720G higher-order cross-connect capacity and 20G lower-order cross-connect capacity. The OSN 9500 provides 40 service board slots, and the utilization of the service board slots can be maximized because they do not need to house optical amplifier boards and dispersion compensation boards. The OSN 9500 provides 1 x STM-64 line boards, 1 x STM-16/2 x STM-16/4 x STM-16/8 x STM-16 line boards, 4 x STM-4 line boards, 16 x STM-4/STM-1 line boards, 16 x STM-1 (optical/electrical interface) line boards, and 6 x GE service interface boards. The high integration of boards increases the service access capability of the OSN 9500.
4. The OSN 9500 has flexible networking capability. It supports various topologies, such as mesh, chain, star, two-fiber/four-fiber ring, ring with chain, intersecting rings, tangent rings, and DNI. Mesh networking can effectively improve bandwidth utilization.
5. The OSN 9500 provides comprehensive protection schemes: The OSN 9500 provides equipment-level protection and network-level protection. (1) Network-level self-healing protection schemes: A. 1+1 or 1:N linear MSP. The service switching takes 0 to 50 ms. B. Two-fiber and four-fiber ring MSP. A two-fiber or four-fiber ring can be formed to protect STM-64 and STM-16 services. The service switching takes 0 to 50 ms. C. Subnetwork connection protection (SNCP). The service switching takes 0 to 50 ms. D. Mesh networking and rerouting protection. The service switching takes 50 ms to several minutes. (2) Equipment-level protection schemes: A. 1+1 hot backup of cross-connect boards. B. 1+1 hot backup of clock boards. C. 1+1 hot backup of system control boards. D. 1+1 hot backup of power input boards (JPIU boards) E. Key power supply backup for boards. The centralized backup of power supplies is implemented for line boards, JCOM boards, or optical power amplifier boards.
6. The OSN 9500 has powerful ECC processing capability. It uses powerful CPUs to provide the ECC processing capability for up to 160 channels based on an advanced system bus structure, fully meeting the requirements of complex networking.
7. The OSN 9500 has a comprehensive network management system. Based on the Windows NT and UNIX operating systems, the OptiX iManager can perform centralized operation, administration, maintenance and provisioning (OAM&P) on a complex network composed of the OSN 9500 and other OptiX optical transmission systems, thereby implementing service configuration and grooming to ensure secure network operation.
8. The OSN 9500 provides power supply and environment monitoring functions. The OSN 9500 adopts the separated power supply mode with dual –48 V/–60 V inputs, provides the maintenance monitoring bus, and monitors the voltage and ambient temperature of the power supplies. The performance is more secure and reliable. The OSN 9500 controls the power-on and power-off of boards, and backs up the key power supplies of boards. The power supplies of service boards, JCOM boards, and optical amplifier boards in line slots can be protected in a centralized manner.
9. The OSN 9500 provides complete synchronization status message (SSM) management functions. It provides the SSM management functions for synchronous clocks and the synchronization clock management and protection switching functions to enhance the reliability of network operation.
