D21S PRO 4 Motor Fiber Fusion Splicer Officially Launched for High Precision Optical Fiber Projects

Huajun International Trade (Qingdao) Co., Ltd. proudly announces the launch of the new D21S PRO 4 Motor Fiber Fusion Splicer, a professional optical fiber splicing solution engineered for telecom operators, contractors, distributors and system integrators worldwide. Designed to deliver exceptional precision, speed and reliability, the D21S PRO offers outstanding performance for FTTH deployment, backbone network construction, metropolitan area networks, data centers and optical cable maintenance. 

Faster Installation Improves Project Efficiency

Construction efficiency is critical in modern fiber deployment projects. The D21S PRO completes fiber splicing in just 7 seconds, while heat shrinking requires only 15 seconds.

Its automatic splicing function starts immediately after the windproof cover is closed, minimizing manual intervention and reducing installation time for field technicians.

Combined with a 5200mAh rechargeable battery supporting approximately 260 splicing and heating cycles, the machine easily handles full-day outdoor operations. 

Designed for Tough Outdoor Working Conditions

Field environments often involve dust, moisture, wind and temperature fluctuations. The D21S PRO features an IP54-rated dustproof and waterproof structure together with a shock-resistant body, enabling stable operation in challenging construction environments.

The operating temperature range from -10°C to +60°C allows reliable performance across diverse climates. 

Wide Applications Across Multiple Industries

The D21S PRO is suitable for numerous fiber optic applications, including:

· FTTH network deployment

· Telecom backbone construction

· Metropolitan area networks

· Data center fiber installation

· Security surveillance systems

· Industrial fiber sensing

· Cable television networks

· Emergency optical fiber repair

Its products comply with international quality standards, including ISO 9001, ISO 14001, ISO 45001 and CE certification requirements. With OEM and ODM services available, the company supports distributors, telecom operators and brand owners with customized solutions for different regional markets. 

D21S PRO is manufactured by the same production team and manufacturing system behind INNO-branded fiber fusion splicers, delivering the same high manufacturing standards with competitive value.
