The intelligent optical transmission equipment is an SDH-based multi-service transmission platform. It has SDH protection and recovery capabilities and OAM capabilities, and supports access and transmission of various services such as PDH, SDH, Ethernet, ATM, and PCM. At the same time, the intelligent characteristic control plane is introduced, the resource allocation is optimized, the network construction cost is reduced, and the network survivability is improved. It is widely used in electric power, transportation, energy and other industries to provide customers with high reliability and low latency optical transmission solutions.
The OSN1500 uses a "uniform switching" architecture to implement unified scheduling of packet services and TDM services, and to build flexible application modes: pure packet mode, pure TDM mode, and mixed mode (packet + TDM). The three modes can be smoothly expanded through service board level expansion, so that the most suitable mode can be used to meet the development requirements of operators' services and networks, so that operators can follow the technological development and industrial chain maturity to carry out step-by-step smooth investment.
Based on the "uniform switching" architecture, the OSN1500 device adopts packet transmission technology to achieve efficient statistical multiplexing of data services, effectively reducing the transmission cost per bit of services, and inheriting the advantages of SDH to provide native bearers for TDM services, effectively ensuring high quality. Voice service delivery.
The OSN1500 optical transceiver is generally applied to the access layer in the metropolitan area transmission network. The hybrid networking of the OptiX OSN1500 is flexible.
The access layer device uses the OptiX OSN1500, OptiX OSN2500, or OptiX OSN500.
The aggregation layer equipment adopts OptiX OSN580, OptiX OSN3500, OptiX OSN7500 or OptiX OSN7500II.
The core layer devices use the OptiX OSN7500, OptiX OSN7500II or CX 600.
At the access layer, the SDH service is transmitted on the STM-1/STM-4 ring; the packet Ethernet service is transmitted on the GE ring.
At the backbone/aggregation layer, the SDH service is transmitted on the STM-16/STM-64 ring; the packet Ethernet service is transmitted on the 10GE ring.
The OSN1500 transmission device can also be connected to the WDM device and the Metro series device. The network application is flexible. Supports traversing third-party Layer 2 networks from the network side for end-to-end configuration and management.
Radio and TV: One network meets the transmission needs of broadcasting services, data and leased lines
With the large customer line business become another business hotspot in the broadcasting industry. The MSTP device implements access, bearer, and scheduling of various types of leased line services. One network simultaneously satisfies the transmission requirements of broadcast, data, and leased line services.
In addition to meeting the basic business needs of the broadcasting industry, the OSN1500 equipment also provides large customer lines for enterprises, finance, government and other industries, so that the network connections of various industries are integrated. The access point is usually an OptiX OSN500/550 device, and the access ring is usually an OptiX OSN3500/580 device; the aggregation ring is usually an OptiX OSN7500 device. The MSTP solution is based on Smart 40G, hard and soft pipes, and MPLS-TP, and is designed to meet the needs of large and medium-sized customers.
