HUAWEI PSXCSA SST1PSXCSA 03020CGK Huawei OSN7500 Super cross clock board Functions and Features: The OptiX OSN 7500 intelligent optical switching system (the OptiX OSN 7500 for short) is the next-generation intelligent optical core switching (OCS) equipment and is developed by Huawei on the basis of the current situation and development trend of the metropolitan area network (MAN). The OptiX OSN 7500 is mainly used as a service scheduling node at the metropolitan backbone layer. That is, it functions as optical core switching equipment (OCS). As an intelligent optical transmission platform and core optical transmission system, the OptiX OSN 7500 is located at the metropolitan backbone layer to schedule and transmit services of different types and granularities. The OptiX OSN 7500 is of a universal switch architecture. That is, the OptiX OSN 7500 can be used in packet mode or in TDM mode. When used with the other equipment of Huawei, the OptiX OSN 7500 supports various networking applications, such as the pure packet mode application, hybrid networking application (overlay networking of the packet mode and TDM mode), and pure TDM mode application. By using a proper networking solution, the data service and conventional SDH service can be processed in the optimal manner. In TDM mode, the OptiX OSN 7500 supports large cross-connect capacities, that is, 360 Gbit/s higher-order cross-connections and 40 Gbit/s lower-order cross-connections. In packet mode, the OptiX OSN 7500 supports 160 Gbit/s packet switching capabilities. In packet mode, the OptiX OSN 7500 supports the following technologies: Multi-Protocol Label Switched-Transport Profile (MPLS-TP) Multi-Protocol Label Switch (MPLS) ETH PWE3 TDM PWE3 ATM PWE3 In TDM mode, the OptiX OSN 7500 supports the following technologies: Synchronous digital hierarchy (SDH) Plesiochronous digital hierarchy (PDH) Ethernet Asynchronous transfer mode (ATM) Storage area network (SAN)/Video Wavelength division multiplexing (WDM) Digital data network (DDN) Microwave Features Universal Switch Architecture, Multi-Service Transmission With a universal switch architecture, the OptiX OSN equipment meets requirements for bearing conventional services and the growing number of packet services. 3G Mobile Backhauling Support, Service Transmission Improvement To address 3G mobile backhauling requirements, Huaweis equipment provides complete transmission solutions in the packet domain, converging and grooming services at the core layer of a wireless network. Built-In WDM/Microwave, Flexible Networking The OptiX OSN equipment uses the built-in WDM technology to transmit several wavelengths over one optical fiber. In this manner, the OptiX OSN equipment can be interconnected with the WDM equipment. The OptiX OSN equipment supports the radio technologies to transmit the conventional SDH service over radio. In this manner, the radio equipment can be used as a substitute to access the SDH service. Board Software The board software runs on each board and it manages, monitors and controls the operation of the board. It receives the command issued from the NE software and reports the board status to the NE software through performance events and alarm. The specific functions include: Alarm management Performance management Configuration management Communication management It directly controls the functional circuits in corresponding boards and implements ITU-T compliant specific functions of the NE. Service Types The OptiX OSN equipment can process the following Ethernet services, ATM services, IMA services, ATM/IMA (E1) services and CES services in packet mode. Types of Ethernet services: E-Line service E-LAN service Types of CES services: CES (E1) service CES (STM-1) service Type of ATM/IMA services:ATM/IMA (E1) service Table 1 Technical specifications of the OptiX OSN 7500 subrack Dimensions (mm) 496.4 (W) x 295 (D) x 756.7 (H) Weight (kg) 30 (net weight of the subrack that is not installed with boards or fans) Table 2 Maximum power consumption of the OptiX OSN 7500 subrack Subrac Type Maximum Power Consumptiona Fuse Capacity Typical Configuration Typical Power Consumption Typical Configuration General OptiX OSN 7500 subrack 1100 W 32 A 663 W ·, Two N1SL64 (S-64.2b, LC) boards ·, Two N3SLQ41 (S-4.1, LC) boards ·, One N1SLT1 (S-1.1, LC) board ·, Three N1PEGS8 (1000BASE-LX, 1310-LC) boards ·, Two N2PEX1 (10GBASE-LR, 1310-LC) boards ·, Two N1PETF8 boards ·, Two T1PSXCSA boards ·, Two N6GSCC boards ·, Two T1PIU boards ·, One T1AUX board ·, One T1EOW board OptiX OSN 7500 type-III subrack 2300 W 63 A 986 W ·, Two N1SL64 (S-64.2b, LC) boards ·, Three N1SLQ41 (S-4.1, LC) boards ·, Two N1SLT1 (S-1.1, LC) boards ·, Four N1PEG8 (1000BASE-LX, 1310-LC) boards ·, Six N2PEX1 (10GBASE-LR, 1310-LC) boards ·, Three N1PETF8 boards ·, Two T1PSXCSA boards ·, Two N6GSCC boards ·, Two T1PIUB boards ·, One T1AUX board ·, One T1EOW board Table 3 Power supply parameters Item Specification Power supply mode DC power supply Nominal voltage -48 V or -60 V Voltage range -38.4 V to -57.6 V or -48 V to -72 V Maximum current 32 A/60 Aa Product details: If you are interested, please let us know the specific model.
