NEC's 5000 and 3000 Series SDH (synchronous digital hierarchy) Microwave Radio Systems cover frequency from 4 to 11 GHz for long-haul transmissions.

The 5000S is designed using the latest technology, and ITS footprint is only an half of the 3000S one. Thus, 5000S can equip up to 10 systems and its complete repeater system occupies only one ETSI rack.
 

Features:

* High system gain due to new forward error correction circuit
* Ten systems per rack
* Two branching circuits per rack
* Built-in multiplexer (optional)

Frequency band:

* 4 to 11 GHz

Transmission capacities:

* STM-1 or OC-3 (155.52 Mbps, electrical or optical interface)
* Fast Ether or Gigabit Ether (with optional multiplexer)
