En Coriant HiT 7025 is a compact, carrier-grade Multi-Service Provisioning Platform (MSPP) designed to deliver both traditional TDM and modern Ethernet-based services within a unified architecture. It supports STM-1, STM-4, and STM-16 interfaces, making it ideal for metro and access network environments where flexibility, reliability, and efficient service delivery are critical. With support for PDH, SDH, and Ethernet payloads, the HiT 7025 allows seamless integration into diverse network infrastructures while maintaining interoperability across multi-vendor systems.
Its modular, scalable design allows the HiT 7025 to function as a terminal multiplexer, add-drop multiplexer, or cross-connect, supporting a variety of deployment topologies including linear, ring, and mesh. The platform offers non-blocking cross-connect capacity of up to 33 Gbps for high-order traffic and 10 Gbps for low-order, supporting key technologies such as GFP, LCAS, and VCAT to enable flexible bandwidth management and dynamic Ethernet service delivery.
At Carritech, we support the full Coriant HiT 7025 system with a comprehensive inventory of tested equipment, spare modules, and replacement parts. Our expertise helps service providers maintain operational continuity, extend the life of their network assets, and plan cost-effective transitions to next-generation technologies. Whether maintaining active networks or securing critical spares, Carritech ensures your HiT 7025 platform continues to perform reliably and efficiently.
