Product characteristics ? Platformization with high performance-price ratio: it is fully compatible with OptiX OSN7500/3500/2500 business boards and software, forming a unified platform, greatly reducing the cost of maintenance and spare parts. In terms of business capabilities, it can be combined efficiently to provide operators with the most cost-effective solutions, At the same time, it can be mixed with Huawei's existing equipment to form a network, and can be integrated into Huawei's optical network management solution for unified management. ? Multi-service provision: the service interface supports STM-1 (O/E), Support STM-1/4/16 standard or cascade service, Support E1/T1/E3/T3/E4, Support the transparent transmission and exchange of FE and GE businesses, Support ATM business, Support SAN business and video business and provide GMPLS-based fast end-to-end business. It can realize flexible equipment configuration and support online upgrade of network equipment from 622M to 2.5G. ? Large-capacity scheduling: support 20G high-order full crossover, high-order 128 ? 128 VC-4, low-order 8064 ? 8064 VC-12 or equivalent VC-3 crossover capability. ? Built-in wavelength division technology and flexible networking: OSN1500B equipment supports built-in WDM technology to realize the transmission of multiple wavelengths in a single optical fiber, and can realize flexible networking scheme of docking with wavelength division equipment. ? Highly integrated subrack and: single subrack has 9 business boards and 4 interface boards. ? Flexible installation mode: box-type equipment, with a height of 5U [the upper 2U is the interface area, and the lower 3U is the processing board], can support the installation of 19 'cabinets, ETSI 300 deep cabinets, and wall-mounted three installation modes. SQB9RACK03 N66T assembled cabinet (2200x600x600mm) (19 inches) can generally meet most user needs. The specific model and size need to be adjusted according to the user's actual machine room environment requirements.
