As the demand for high-volume data transmission accelerates, radio systems need capacity large enough to
accommodate the evolving market.
The optimal solution for more stable, reliable long-term performance is the 5000S-the high-capacity Synchronous
Digital Hierarchy (SDH) long-haul microwave radio system made by NEC for synchronous transport module level 1
(STM-1) and optical carrier level 3 (OC-3) data transmission.
NEC SDH (Synchronous Digital Hierarchy) transmission equipment for a range of configurations includes an
add-drop-multiplexer and an NMS (Network Management System). Various systems applications such as N+1
Frequency Diversity (FD)/Space Diversity (SD) and Hot-Standby (HS) protection switching systems are available.
Expand an existing system configuration simply by adding modules and/or sub-racks to boost transmission capacity.
Up to 10 systems with MUX (Multiplexer) can be built into a single ETSI rack.
A complete NEC broadband transmission package, including training and managed service, can maximize the value of
your capital and operating expenditures (CAPEX and OPEX). Upgrade speed and capacity at every stage from
feasibility study to survey and up to implementation. Gain advantage and apply it on a global scale. The long-term
success of your broadband transmission operation depends on it.
5000S
Features:
Total Design concept
The NEC family of SDH system equipment features a highly compatible, unified design platform. 5000S microwave system technology is based on the longstanding integrity of NEC expertise. With its advanced integrated design, the 5000S accommodates higher rack density than other systems of its kind. The equipment comprises two main shelves on a single European Telecommunications Institute (ETSI) rack. Branching (BR) and Transmitter/Receiver Equipment (TRP) sections are built on the upper shelf, with Modulator/Demodulator Equipment (MDP) and Multiplexer (MUX) sections on the lower shelf.
