Nokia 472501A.103 FXEB Flexi series base stations

Nokia 472501A.103 FXEB is a tri-channel RF module dedicated to Nokia Flexi series base stations, operating in the 1800MHz frequency band. Commonly used as a base station radio frequency unit, it is a key device supporting signal transmission in wireless communication networks and is compatible with Nokia NSN base station systems. Based on circulating product information, the detailed introduction is as follows:

I. Core Technical Parameters

This module supports three-channel 80W power output and is adapted to the 1800MHz communication frequency band. Specifically, its transmit frequency range is 1805 - 1880MHz, and the receive frequency range is 1710 - 1785MHz. It features an instantaneous downlink bandwidth of 35MHz, an instantaneous uplink bandwidth of 60MHz, and a filtering bandwidth of 75MHz for both uplink and downlink, fully meeting the requirements of wireless communication signal transmission and reception in this frequency band. Equipped with a rich interface configuration, it includes a power input interface, 6 7/16 female antenna interfaces, 3 QMA female receiving interfaces, an 8-pin circular interface, a shielded RJ45 female interface, and SFP optical module interfaces supporting 3GB or 6GB rates, enabling multiple functions such as power supply, signal interaction, and data transmission.

II. Adaptation & Compatibility Characteristics

As a member of the Nokia Flexi RF module series, it is perfectly compatible with Nokia Flexi series base station systems and can seamlessly connect with modules such as baseband processing units in the system to form a complete communication link, without the need for major modifications to the existing base station architecture. Meanwhile, as a dedicated accessory for Nokia NSN base stations, it adheres to the general adaptation standards of this series of base stations, facilitating equipment replacement and capacity expansion for operators in existing network maintenance.

III. Application Scenarios

This module is widely used in 1800MHz frequency band wireless communication base stations built by Nokia, including scenarios such as base stations undertaking high-traffic communication services in dense urban areas and wide-coverage base stations in suburban regions. It can efficiently complete the conversion between optical signals from baseband units and wireless RF signals, ensuring signal transmission between terminal devices and the core network. In addition, it is also a common spare part in base station operation and maintenance. When the original RF module of a base station experiences faults such as abnormal power output or signal interruption, replacing it with this module can quickly restore the normal communication capability of the base station and reduce network downtime.

IV. Product Supply & Packaging

Both brand-new and refurbished products are available on the market. Most suppliers conduct comprehensive inspections on the products and provide a one-year warranty service, while some suppliers also offer after-sales technical support. The single unit weight of the product is approximately 25kg, with dimensions of 560×530×170mm. The packaging usually adopts standard export packaging, generally a combination of anti-static packaging and cartons. For bulk purchases, customized packaging can be negotiated, and transportation is often carried out through international courier channels such as DHL and UPS.
