This set of photos fully displays the complete structure of D38999/20WB04A1N industrial circular fiber connection cable. One end adopts D38999 series circular metal connector with buckle locking structure, matched with anti-drop steel wire rope for protection; the other end is equipped with four LC fiber terminals for optical signal docking. The outer fiber wire adopts wear-resistant black sheath, neatly arranged with clear wire marking, which is convenient for wiring identification and on-site installation. The sealing structure of the circular connector brings good dustproof and waterproof ability, meeting the wiring requirements of various industrial scenarios.


Product overview
D38999/20WB04A1N is a rugged industrial circular fiber connection cable, professionally used for stable optical signal transmission in industrial equipment. The circular metal connector features built-in sealing and shielding design, effectively resisting electromagnetic interference, water, dust and vibration. Matched with standard LC fiber connectors, it realizes convenient plug-and-play optical access. The fiber cable has strong tensile resistance and aging resistance, adapting to long-term use in indoor and outdoor complex industrial environments such as automation equipment, industrial control systems, testing instruments and communication equipment. All products undergo strict optical performance testing to ensure consistent transmission quality in mass production, supporting customized cable length for global industrial matching and export.


Workshop
Our factory runs standardized closed production workshops dedicated to industrial fiber connectors and fiber jumpers. The production line covers CNC precision machining of metal connectors, optical fiber stripping, fiber fusion splicing, terminal assembly, sealing processing and finished product testing. Every production step implements standardized process management: raw material incoming inspection, semi-finished product sampling, optical loss testing, environmental aging test and waterproof vibration test. We equip professional optical testing instruments to verify signal transmission stability. Unified operation standards guarantee consistent product performance during mass production, capable of undertaking large-scale global orders with stable delivery cycles.



Exhibition
We regularly participate in international industrial automation, communication and electronic equipment exhibitions worldwide. We showcase full-series industrial circular fiber cables including D38999 series fiber connection lines to global buyers, equipment manufacturers and system integrators. Through offline face-to-face communication, we fully understand customers’ on-site wiring environment, signal transmission needs and length customization requirements, and provide targeted optical wiring solutions. Long-term stable cooperative relations have been established with customers from various regions relying on reliable product quality and flexible customization service.


Package
Each D38999/20WB04A1N fiber cable is individually wrapped with anti-static bubble film to prevent scratch and extrusion damage. Single product is put into an independent sealed plastic box or white carton for dust and moisture protection. Multiple individual packages are sorted and packed into thickened export corrugated cartons with shipping marks. We support multiple international shipping options including DHL, FedEx, air freight and sea freight. All packaging is shockproof and pressure-resistant to ensure intact delivery of fiber cables to overseas destinations.
