Highlights at a glance
SURPASS hiT 7500 is a future-proof DWDM transport platform optimized for building ultra-high capacity regional, long-haul (LH) and ultra-long-haul (ULH) networks. The platform transports 10 Gbit/s per chan — nel and is prepared for a channel capacity of 40 Gbit/s. Additional investments in other platforms for different applications are not necessary. The system consists of several network elements (NE) including optical transport terminals (OTT), optical line repeaters (OLR), optical add/drop multiplexers (OADM) and the optical channel unit providing multiplexing transponder units. It also offers optical protection cards. Compound NEs such as OTTC (transpon — ders and transport terminals in one NE) is supported.

A major asset for carriers
The SURPASS hiT 7500 DWDM platform has a wealth of features that benefit network operators. The common nature of the platform saves staff training time and costs, simplifies the carrier’s network and also reduces the range of spare parts that need to be stocked. The system’s modularity allows optimization of network solutions according to need and minimizing the number of network components leads to lower CAPEX and OPEX. This DWDM platform is future-proof, prepared to handle 40 Gbit/s capacity per channel and its tiny footprint also saves on operational costs.
The implementation of G.709 enables the network management system to intelligently monitor and manage multiple wave — lengths with single wavelength granularity. End-to-end supervision and management is possible through-out the DWDM network. Comprehensive management support for fault localization, configuration management, performance analysis and automatic analysis of optical paths further reduce SURPASS hiT 7500 constitutes a leading and future-proof cost-optimized DWDM platform for regional up to ultra-long-haul applications for bothsmall and large carriers. The product is constantly being improved to further enhance network efficiency. SURPASS hiT 7500 helps turn band — width into positive cash flow and ensures the profitability of current business operations and a fast return on investment.Highly adaptable
SURPASS hiT 7500 can be customized for all applications, thus permitting optimum investment in DWDM technology. Transparent optical networking with 100% OADM lowers the cost of electrical regeneration. The 100% OADM can be configured remotely to redirect data streams with minimal effort simultaneously with the customer’s service request. This highly automated system using OPA enables easy and fast upgrading of new services, resulting in considerable OPEX savings. Release upgrades of SURPASS hiT 7500 are carried out by remote software download without affecting operation. Transponder and regenerator functionality for 10 Gbit/s as well as service aggregation using a 10 Gbit/s multiplexing transponder for 2.5 Gbit/scan be supported. All common protection mechanisms are supported.
SURPASS hiT 7500 is fully integrated into TNMS, Siemens’ best-in-class network management system.
Wide-ranging support
SURPASS hiT 7500 supports all kinds of network architectures (point-to-point, ring, mesh). It adapts all types of services to the DWDM layer through use of transponders, it multiplexes a high number of wave — lengths (up to 160) on one fiber, and optically amplifies the combined signal.
Due to its high system flexibility, the SURPASS hiT 7500 platform is costoptimized for regional links (500-800 km) and ULH links (3,000 km), and is well suited to the needs of carriers running networks with a wide variety of link lengths.
Additional features
Due to the flexible 100% OADM based on multi-wavelength blocker, there is no need for pre-planning of both express and add/drop wavelength. Furthermore the 100% OADM concept enables a future extension to a transparent optical net — working node (photonic switch). Built-in enhanced optical monitoring capability with OPA, based on power measurements, supports fast pre-emphasis and link control, fully automatic operation control and fast channel upgrade. The 10 Gbit/s transponder supports STM-64/OC-192 and 10GbE WAN in accordance with IEEE 802.3ae, while the 10 Gbit/s multiplexing transponder supports STM-16/OC-48 and aggregated GbE/FC/STM-4.
