Detailed Product Description

The 3000S series synchronous digital system (SDH) long-distance microwave wireless system is designed for the transmission of a synchronous transmission model (stm-1) or optical interface (oc-3).

Its working frequency covers 4-11ghz, using 64 or 128 quadrature amplitude modulation (QAM), and its transmission capacity is stm-1 or oc-3 per rf channel.

Frequency range: 4-11ghz
Capacity: 155.52Mbps/ system
. Modulation mode: 64QAM, 128QAM
. Configuration: N+0 (N: 1-4), N+1 (N: 1-3)
In line with the latest standards
Multiple system applications and simple capacity expansion
. Digital modem demodulation: the full digital modem with the decision feedback equalizer (DFE) USES NEC's highly reliable LSI.
. MLCM and MLCM+RS modulation system with better error performance.
With automatic transmission power control function
. Co-phase (IP) and minimum dispersion (MID) synthesis space diversity technology
Space diversity system using electrical difference absolute delay equalization (DADE) a variety of synchronous clocks
. Adjacent branch circuit
Adaptive equalizer
Multiple synchronous clocks
. Sync status information (SSM)
Rich line segment SOH
. Various stm-1 interfaces
Multiplexed segment protection (MSP)
Bipolar code conversion to provide 1+1 protection port
Rich digital service channels and bypasses: in addition to the main signal transmission, 1* (192bit/s or 64 bit/s) +4*64 bit/s
. DSC and one or two (2 or 1.5M bit/s) WS channels can be separately and multiplexed to a microwave terminal or relay station.
With the functions of fast service and general service
