The following is a detailed introduction to each category of cables. Each cable is customized according to original factory specifications, 100% compatible with all Nokia Flexi Multiradio and AirScale series macro base stations, requiring no additional adapter debugging, plug-and-play, which greatly improves project efficiency and reduces operation and maintenance costs.
1. Outdoor/Indoor Fiber Optic Jumpers (Core Signal Transmission)
As the "lifeline" of base station signal transmission, this category accounts for the highest proportion (about 30 models), and its core purpose is to realize the lossless transmission of CPRI/eCPRI high-speed digital signals between BBU (Baseband Unit) and RRU (Remote Radio Unit), which directly determines the base station signal coverage and transmission quality. The products are divided into indoor dust-proof models (ID interface) and outdoor waterproof models (OD interface, IP67 protection), covering two specifications: Single Mode (SM, 9/125um) and Multi Mode (MM, 50/125um or 62.5/125um), with a cable diameter of 5.0mm and equipped with NSN Uni‑Boot special connectors. They have the characteristics of UV resistance, high and low temperature resistance (-40℃~+85℃) and strong anti-interference ability, adapting to all scenarios such as tower-mounted remote, cabinet internal connection, indoor distribution system and FTTA (Fiber to the Antenna). Among the typical models, 473905A is a Multi Mode (MM) dual-core LC OD interface with a length of 80m; 473265A and 473289A are Single Mode (SM), with DLC/ID-DLC/ID*2 interface and DLC/OD-DFC/ID interface respectively, adapting to different scenario needs.
2. DC High-Current Power Cables (Power Supply)
Its core purpose is to provide stable -48V DC power for core base station equipment such as RRU and radio frequency modules, and it is the "power source" for base station operation. It adopts high-purity oxygen-free copper conductors with excellent electrical conductivity and strong high-current bearing capacity, combined with special outer sheath that is high temperature resistant, anti-aging, tensile and torsion resistant, with firm connection and no loosening. It can be directly connected to PDU (Power Distribution Unit) and base station radio frequency modules (such as FZHF, FZJA, FSMF) to ensure zero interruption and zero loss of power transmission. The core typical model is 995281B (high-current model), which is specially designed for Nokia Flexi Multiradio base station system and perfectly matches the power supply needs of Flexi and AirScale series base stations.
3. Synchronization Clock Cables (Network Stability)
Specially designed to ensure precise synchronization of base station clocks, its core function is to realize base station frame alignment and unified global time, avoiding call freezes, data delays, signal loss and other problems caused by clock deviation, which is the key to the stable operation of 4G/5G networks. This cable is dedicated to Nokia Flexi Multiradio and AirScale base stations, with high transmission accuracy and strong anti-interference ability. The core typical model is 472685A (ESFB Sync Cable), which can realize precise synchronization between ESM module and FSMF/ASIK, escorting the stable operation of the network.
4. System Interface/Signaling Control Cables (Device Interconnection)
It undertakes the core task of interconnection between internal base station equipment and external communication, and is used for the transmission of Ethernet signals, control signals and maintenance signals between the main control module, interface board and external equipment. It is the "communication bridge" for the base station to issue instructions, exchange data and carry out operation and maintenance debugging. The interface strictly follows Nokia's original factory specifications, with stable connection and efficient transmission. The typical models are 471371A (Flexi system interface cable, used for interconnection between FSMF/FSMB and FSIP modules) and 474118A (HDMI form maintenance cable, used for connection between base station main unit and laptop/LMT terminal, transmitting Ethernet and control signals, not video signals), adapting to the Flexi Multiradio base station platform.
5. External Alarm & Control Cables (Safety Protection)
Focusing on base station environmental monitoring and safety protection, its core purpose is to connect the base station main control module with external environmental monitoring equipment (door magnetic, temperature sensor, smoke sensor, fan, lighting, etc.), collect real-time base station operation environment parameters, send alarm signals in a timely manner when abnormalities occur, and remotely control the operation of external equipment, reducing operation and maintenance risks and protecting the safety of base station equipment. The core model is 472839A (FTSI System Adapter Hub EAC Cable), which is used as an interface hub cable, compatible with all Nokia Flexi Multiradio and AirScale series base stations, waterproof, dust-proof and anti-interference, adapting to complex outdoor and cabinet environments.
6. AISG/Remote Electrical Tilt (RET) Antenna Control Cables (Coverage Optimization)
Specially designed to optimize base station signal coverage, its core purpose is to connect RRU and RET antenna, realizing remote adjustment of antenna downtilt and azimuth. Without the need for staff to work at heights, it can flexibly optimize the signal coverage range, reduce signal blind areas, improve network service quality, and reduce operation and maintenance costs and operational risks. This type of cable strictly follows the AISG 2.0 standard, adopts RJ45 waterproof interface and CAT5e shielded material, and is perfectly compatible with AirScale series base stations.
