Product Description The OSN 2500 works at the 2.5Gbit/s or 622Mbit/s level, inherits all features of the MSTP technology, keeps compatible with traditional SDH and MSTP networks, and integrates the SDH, PDH, DDN, Ethernet, WDM, ATM, IMA, and RPR, ESCON, FICON, FC and DVB-ASI (Digital Video Broadcast-Asynchronous Serial Interface) . OSN 2500 is used in aggregation layer & access layer, and its service board is compatible with OSN 9560 /7500II /7500 /3500 /2500 /1500. OSN 2500 supports intelligent features, automatic end-to-end service configuration, SLA, traffic engineering, timeslot defragmentation, MESH clock synchronization etc. to enhance network utilization. The OptiX OSN 2500 intelligent optical transmission system (hereinafter referred to as the OptiX OSN 2500) developed by Huawei is the next-generation intelligent optical transmission equipment. The OptiX OSN 2500 integrates the following technologies to transmit voice and data services on the same platform with high efficiency: Synchronous digital hierarchy (SDH) Plesiochronous digital hierarchy (PDH) Ethernet RPR(Resilient Packet Ring) Asynchronous transfer mode (ATM) Storage area network (SAN) Wavelength division multiplexing (WDM) Digital data network (DDN) Automatically switched optical network (ASON) Microwave Technology The OptiX OSN 2500 subrack has a one-layer structure. The subrack consists of the slot area for processing boards, slot area for interface boards, slot area for the auxiliary interface board, power supply area and fan area.
