Transport systems based on SDH (Synchronous Digital Hierarchy) dominate today's transmission technology.
Synchronous multiplexers are suitable for use in any network structure in the edge and regional layer of a transport network and are used in particular in add-drop and terminal applications.
Synchronous line systems are utilized in chain and ring structures and in high-capacity links. They are implemented in regional and metropolitan network layers as well as in national and international backbone networks.
The Siemens TransXpress SLD16 series2 is supplied with cross-connect matrices of VC-4 granularity. All SDH line interfaces exhibit full DWDM (Dense Wavelength Division Multiplexing) capability.
TransXpress SMA1 and SMA4 - SDH multiplexer
Siemens state-of-the-art SDH transport and multiplex technology allows for optimal usage of limited resources. The unique combination of ring, card and path protection and the large bandwidth of SDH interfaces forms the basis for the creation of any network scenario imaginable. TransXpress SMA1 and SMA4 are perfectly suited for implementation in regional and metropolitan network layers as well as backbone networks.
TransXpress SMA1K - Ultracompact STM-1 multiplexer
TransXpress SMA1K, our LSI synchronous multiplexer, provides an ultracompact and flexible solution for SDH network applications. TransXpress SMA1K combines the advantages of SDH and Ethernet in a single unit. This STM-1 Mltiplexer is optimized to economically provide high-performance megabit pipelines for WAN access solutions. It allows extending reliable SDH technology to the customer's premises. Due to its compactness, it is also well-suited as a transport multiplexer for installation in street cabinets and on customer premises.
TransXpress SXA - SDH Cross-connect
TransXpress SXA is the most advanced SDH digital cross-connect available on the market. It is designed to be the most competitive solution for the collection and redistribution of 2, 34, 45 140 , 155, 622 Mbit/s and 2.5 Gbit/s signals for application areas in both metropolitan areas and in regional networks.
TransXpress SXD - SDH Cross-connect
The SXD series 3 is a broadband cross-connect system with VC-4 switching granularity.
SXD is a future-oriented network element that implements the most complete set of features of any other 4/4 network element on the market.
The architecture and design of SXD give a huge degree of flexibility to the networks in which it is installed.
SXD series 3 is the perfect solution in backbone applications in conjunction with DWDM technologies and, thanks to its concatenation features, within IP traffic networks.
Many upgrade possibilities and optional functionality have been implemented to allow better in-field deployment and to reach a broader range of customers.
Cross-connects are becoming key elements in networks as points of flexibility. They are the drivers in DWDM applications and the gateways for IP traffic.
TransXpress SMA1K-CP - STM-1 Multiplexer for CPE Application
TransXpress SMA1K-CP is a cost-effective and compact STM-1 multiplexer optimized to provide 2 Mbit/s, 34/45 Mbit/s as well as 10/100 BaseT Ethernet services to residential and business customers. TransXpress SMA1K-CP combines the advantages of SDH and Ethernet in a single unit. Through the high level of integration it was possible to implement full terminal and add/drop multiplexer functionality in a single unit. Due to its compactness, SMA1K-CP is extremely well suited for desktop installation in offices or cabinets at customer premises. Wall and rack mounting options are also available.
