PASOLINK NEO/c

NEC has developed the PASOLINK NEO/c, a narrow band point-to-point digital microwave relay system operating at radio frequency (RF) bands of 7/8/13/15/18/23/26/38 GHz.
This system meets an increasing demand for digital transmission services, and will satisfy the needs for common carrier access links, private links, urban area networks, rural area networks, temporary networks or emergency links for voice and data transmissions. Especially this system is very usefully for backbone network of mobile system.

This PASOLINK equipment offers very high performance with large system flexibility, which is easy to install and is a field proven to be very reliable. It means this equipment contribute to reduce the cost of CAPEX and OPEX.
The PASOLINK NEO/c system has powerful interfaces for PDH and LAN that covers 5 to 16 x E1, 2 x 10/100 Base-T(X) signals.

The systems consist of antennas, outdoor unit (ODU) and Indoor unit (IDU) same as other PASOLINK series. They are connected through a coaxial cable for each radio channel. Available configurations are non-protected type (1+0) and protected type (1+1). The protected type is available for twin-path type, hot-standby type. Furthermore for long distance transmission, space diversity system is available.
Additionally NEO/c equipment has the capability for changing modulation (QPSK / 16AM) and capacity (5 to 16 x E1) by software setting without any hardware replaces. 5 to 16 x E1.

Features:

• 10/100BASE-T(X) Interface (1+1/1+0 Expandable)
  In addition to the current E1 interfaces, two 10/100 BASE-T(X) interface ports are provided. They enable flexible allocation of bandwidth between E1 and 10BASE-T traffic. Each of the 10/100BASE-T(X) channels can be assigned any of the following data rates: 10 to 40 Mbps, and the remaining capacity can be allotted to E1 usage.
• Automatic Transmitter Power Control (ATPC)
  ATPC reduces interference affecting nearby systems, improves residual BER performance, and alleviates up-fade problem.
• Hitless Switch (1+1)
  Can be used to provide an antenna space diversity system.
• Transversal Equalizer
  Helps compensate for selective fading.
• Received Signal Level (RSL) Monitoring
  Continuous monitoring mode is available through the Local Craft Terminal.
• Powerful Forward Error Correction (FEC)
  Reed-Solomon FEC realizes excellent transmission characteristics.
• Good maintenability with advanced PNMSj

Frequencies:

• 7, 8, 13, 15, 18, 23, 26, 38 GHz

Traffic Capacities:

• 5 x 2 Mbps, 10 x 2 Mbps, 16 x 2 Mbps
