Network operators that require high availability and high capacity operation under a variety of challenging environmental circumstances recognize and trust NEC’s iPASOLINK ODUs for their reliability and market-leading performance. The new IAP3 series ODUs maintain high quality while offering dramatically increased RF performance in an energy-efficient, compact, and lightweight package.

The new IAP3 improves transmission power by up to 5dB in higher modulations, which is critical for operators looking for high capacity links with good availability. The IAP3 offers channel widths up to 112 MHz and adaptive modulation (AMR) up to 4096 QAM in the 6 to 23 GHz frequencies.

The IAP3 has automatic transmitter power control (ATPC) enabled, ensuring efficient operation and support for all common radio configurations, including Cross Polarization Interference Cancellation (XPIC) and Space Diversity. The new N-on-1 hybrid coupler also fully supports the IAP3.

The N-on-1 hybrid coupler is a simple way for operators to boost capacity and availability. It also provides more versatility, allowing operators to combine channels from different frequency bands or use several channels in a single band. Furthermore, because the system uses the same IAP3 and IAG3 ODUs as other sections of the network, inventory is considerably reduced. Operators can start with a single channel and increase as spectrum becomes available in the future, reusing and redeploying ODUs from other areas of the network. The N-on-1 hybrid is available in a small, light direct mount package that reduces tower hardware requirements.

NEC also announced the availability of the next-generation Outdoor Branching Combiner (OBC2), which supports capacities up to 10 Gbps and offers customizable configurations up to 16 radio channels (8 channels in both polarizations) in ACAP, ACCP, CCDP, and CCDP+ACCP combinations. Field upgrades are easier with the new architecture, and Space Diversity is supported with a simple cascade option.

The OBC2 has been lowered in size by half and weight by up to 80%, lowering overall tower loading and aperture requirements. Furthermore, the IP66-rated structure ensures trouble-free operation even in the harshest outside conditions. The OBC2 supports larger modulations up to 4096 QAM and provides greater RF performance by reducing insertion loss and signal distortion in the branching circuit, resulting in lower transmission power losses.

“NEC continues to develop innovative products to meet the needs of our customers. The bundling of bandwidth with configurations that combine high-power and flexible channel organization, which allows for faster transport, is a critical factor for 5G. Customers can extend the capabilities and flexibility of wireless solutions for 5G by using NEC’s high-power ODUs and the next-generation Outdoor BR Combiner “NEC Corporation’s Deputy General Manager, Wireless Solutions Division, Hideyuki Muto, stated.

Both the IAP3 and the OBC2 are part of NEC’s end-to-end 5G network infrastructure solutions, which include RAN, core network, optical and wireless transport, Orchestration / Marketplace (BSS), and a variety of network infrastructure services.
