iPASOLINK EX (Ethernet)

To provide reliable digital access links and fully exploit the full potential of end-to-end advanced networks, NEC has developed the iPASOLINK EX, a 250 / 500MHz bandwidth point-to-point microwave relay system operating in the lightly licensed 71-86 GHz Millimeter Wave E-band frequency spectrum.

iPASOLINK EXThe iPASOLINK EX offers very high performance with extensive system flexibility, ease of installation, field-proven reliability and very low total cost of ownership. Supporting transmission rates up to 3Gbps out of the box, or optional pay-as-you-grow steps, the iPASOLINK EX delivers the scalability to accommodate future application and capacity needs.


With its robust hitless adaptive modulation from QPSK to 256QAM, iPASOLINK EX transports critical traffic with super high dependability. A variety of configuration options are available to meet a range of network requirements and budget mandates.


Advanced Features


Enhanced QoS functions allow finely-tuned bandwidth control and management on a per-flow basis. iPASOLINK EX provides 8 classes of QoS mapping with DWRR or Strict Priority scheduling.


High spectrum efficiency is realized with the hitless adaptive modulation switching from QPSK to 256QAM. Forward Error Correction and linear distortion cancellation techniques deliver high system gain for overall cost reduction. FCC spectrum is lightly licensed in the 80GHz band, making it quick and easy to deploy the iPASOLINK EX, even in congested metro areas. 


Ethernet OAM fault detection, fault isolation and performance measurement and monitoring offer comprehensive system manageability. Synchronization options include Sync-E (ITU-T G.8261 / G.8262 / G.8264) and precision clock synchronization protocol (IEEE1588v2). 


VLAN services are supported by an 8000 MAC ID learning table, 2048 port-based VLAN’s, MEF 9 Certified EPL/EVPL and ELAN services with L2CP tunneling, and 9600 byte jumbo frames.


Benefits of 80GHz Millimeter Wave Transport


Availability of Licensed Spectrum — Licensed frequency spectrum is difficult, and sometimes impossible to obtain in highly congested metropolitan areas. The 80GHz band utilizes highly directional "pencil-beam" signal characteristics which allows multiple system deployment in close proximity without interference. 


Low-Cost “Light Licensing” — The FCC has made it easy to deploy links in the 80GHz band by offering non-exclusive nationwide licenses, followed by coordination and registration on a per link basis through several 3rd party Database Managers. Processing times of 1-2 days is typical.


Small Antenna Sizes — Due to its short wavelengths, the millimeter wave systems achieve high system gain with highly directive transmission using very small antennas, typically either 1 or 2 ft. diameter.


Effective Frequency Reuse — The high directivity of millimeter wave antennas creates opportunity to deploy a greater quantity of systems within a given space. The resulting efficiency of “airspace” utilization provides more bandwidth for communications traffic.


Ultra-high Capacity — Wide bandwidths coupled with the high order modulation (256QAM) of the iPASOLINK EX delivers throughput in excess of 3.2GBps per channel. Use of the XPIC feature available on the iPASOLINK EX doubles that capacity. The iPASOLINK EX provides multi-gigabit capacity in a compact all outdoor enclosure. Furthermore, the iPASOLINK series boasts industry leading extreme low latency architecture and pioneered the use of Gallium Nitride (GaN) to triple transmitter output power while minimizing energy usage and costs.
